What is LED light therapy and how does the mask work?

What is LED light therapy and how does the mask work? What is LED light therapy? LED stands for Light Emitting Diode. LED light therapy uses specific wavelengths of light to interact with the skin at a cellular level — stimulating natural processes like collagen production, cell regeneration, and bacterial reduction without heat, UV, or any invasive treatment. It has been used in professional skincare clinics and dermatology settings for decades, and at-home LED devices have made the technology accessible for daily use. How does light affect the skin? Different wavelengths of light penetrate the skin to different depths and trigger different biological responses. The CHOUOHC Radiance LED Mask uses four wavelengths: Red LED Penetrates into the dermis (the deeper layer of skin) to stimulate collagen and elastin production. Helps improve skin firmness, reduce the appearance of fine lines and wrinkles, and support skin cell renewal. Blue LED Works primarily at the surface of the skin. Has antibacterial properties that help reduce acne-causing bacteria, calm inflammation, and support clearer skin. Yellow LED Targets the epidermis (the outer skin layer) to stimulate cell metabolism and improve the skin's natural renewal process. Helps with skin brightening, dark spots, and an uneven skin tone. Near-infrared (NIR) Near-infrared light is invisible to the human eye, but it penetrates the deepest of all four wavelengths — reaching into the dermis and beyond. It enhances the collagen-stimulating effects of red light, supports tissue repair, and improves overall skin elasticity. If you don't see it glowing, that's normal — it's working beneath the visible surface. Does it work on darker skin tones? Yes. The CHOUOHC Radiance LED Mask works across all skin tones. LED light therapy operates at the cellular level using light wavelengths — it is not affected by the amount of melanin in the skin, and there is no adaptation or adjustment needed for deeper skin tones. The mask is equally effective whether your skin is fair, medium, or dark. Is it safe? LED light therapy does not use UV light and does not damage the skin. It is non-invasive, non-thermal (the warmth you may feel is mild and normal), and has no downtime. It is one of the most well-tolerated skincare technologies available. For guidance on whether it is right for your specific situation — including if you have any medical conditions, take certain medications, or are pregnant — see our Is the mask safe for me to use? article. What results can I expect? Results are gradual and cumulative — LED therapy is not an instant fix, but a sustained practice. Most users begin noticing texture and tone improvements within 2–4 weeks of consistent use, with more significant changes to firmness and fine lines becoming visible at 8–12 weeks and beyond. See our How often should I use the mask? article for guidance on frequency and realistic timelines.

Can I use the mask if I've had fillers, Botox, or cosmetic procedures?

Can I use the mask if I've had fillers, Botox, or cosmetic procedures? This is one of the most common questions we receive, and the honest answer is: it depends on the procedure and how recently it was done. We always recommend checking with your treating practitioner before use, as they know the specifics of your treatment. Here is general guidance for the most common situations. Botox (botulinum toxin injections) Most practitioners advise waiting at least 2 weeks after Botox before using any facial devices, including LED masks. This allows the product to fully settle and reduces any risk of it migrating from the injection site. After the settling period, LED light therapy is generally considered compatible with Botox and may even support skin quality between treatments. When in doubt, ask your injector — they can give you a specific clearance timeline based on your treatment. Dermal fillers (hyaluronic acid, etc.) Similarly, it is generally recommended to wait 2–4 weeks after filler injections before using LED devices — particularly any that involve heat or light near the treated area. LED therapy is low-heat and non-invasive, but giving your skin adequate time to settle after any injectable treatment is good practice. Your practitioner may clear you sooner depending on the product used and the treatment area. Recent surgical or cosmetic procedures (facelifts, laser treatments, chemical peels) If you have recently undergone a surgical procedure such as a facelift, or a more intensive treatment like ablative laser resurfacing or a deep chemical peel, wait until your skin is fully healed before introducing any new device. This typically means receiving explicit clearance from your surgeon or dermatologist before resuming device use. Mild chemical peels or superficial treatments may have a shorter recovery window — again, your practitioner is the best person to advise on this. Active skin conditions in the treatment area Do not use the mask over areas with active wounds, open skin, infections, or skin that is still in the healing phase from any procedure. Once the skin has fully healed and you have been cleared by your provider, use can resume. The bottom line LED light therapy is gentle and non-invasive, and is commonly used by skincare professionals alongside injectable and cosmetic treatments. The main consideration is timing — giving your skin adequate recovery time after any procedure before introducing a device. If you have a specific procedure or treatment in mind and are unsure, your treating practitioner is always the right person to ask. You're also welcome to reach out to us at support@chouohctokyo.com and we'll do our best to help.

What skincare products can I use with the mask?

What skincare products can I use with the mask? Before your session — clean skin only For best results, use the mask on a completely clean face with no products on the skin. That means no serum, moisturiser, SPF, makeup, or oils before or during your session. LED light therapy works by delivering specific wavelengths of light directly to the skin. Applying products beforehand can create a barrier that reduces how effectively the light penetrates — so a clean face gives you the best treatment. Your pre-session routine: 1. Cleanse your face thoroughly 2. Pat dry 3. Put the mask on — no products needed After your session — apply products as normal Once your session is complete, your skincare routine continues as normal. You can apply serums, moisturisers, SPF, or any other products you use after cleansing. Many people find this a good time to apply treatment products as the skin has just been stimulated. Do not leave products on the mask If any serum, gel, or skincare product gets onto the mask itself during or after use, wipe it off with a soft damp cloth before storing. Leaving product residue on the device can degrade the surface over time.

Is the LED light safe for my eyes?

Is the LED light safe for my eyes? Yes. The CHOUOHC Radiance LED Mask has built-in eye protection — the eye pad sits directly over your eyes during use, shielding them from direct light exposure throughout the session. Do I need to wear goggles or additional eye protection? No. The built-in eye pad is designed specifically for this purpose. You don't need to source or wear any additional eye protection — just make sure the eye pad is properly attached and seated against your face before starting a session. Should I avoid looking at the lights? The eye pad covers your eyes during normal use, so you shouldn't be looking at the LEDs at all. As a general rule, avoid looking directly into any bright light source — not because LED therapy light is dangerous, but simply because staring at any concentrated bright light can cause eye strain. This is the same reason you wouldn't stare directly at a bright lamp or the sun. As long as you're wearing the mask correctly with the eye pad in place, your eyes are protected. A note on the eye pad The eye pad is removable for cleaning. If it becomes heavily soiled, you can detach it, rinse it with water, and allow it to dry completely before reattaching. Do not use the mask if the eye pad is not fully and securely attached — confirm there are no gaps between the pad and the mask before each session. See our Caring for your mask article for full cleaning instructions.

Can the mask help with dark spots and hyperpigmentation?

Can the mask help with dark spots and hyperpigmentation? Yes. The CHOUOHC Radiance LED Mask specifically targets dark spots, uneven skin tone, and hyperpigmentation through Mode 5 — a dedicated 20-minute brightening treatment using red and yellow LED light. Why yellow and red light work for hyperpigmentation Dark spots form when melanin — the pigment responsible for skin colour — accumulates unevenly in the epidermis, typically as a result of sun exposure, hormonal changes, post-acne scarring, or skin inflammation. Yellow LED light works directly at the epidermal level, stimulating cell metabolism and accelerating the skin's natural process of breaking down and dispersing excess melanin. Over time this helps fade existing dark spots and even out skin tone. Red LED supports this process by promoting cell renewal and improving overall skin health at a deeper level, helping the skin turn over and replace pigmented cells more efficiently. Which mode to use Mode 5 is the dedicated mode for dark spots, hyperpigmentation, and dullness. It runs for 20 minutes using red and yellow LEDs only — it is also the only mode with no near-infrared light, which makes it suitable for anyone who has been advised to avoid NIR. For more targeted collagen support alongside brightening — for example if you're dealing with both dark spots and signs of ageing — you can rotate Mode 5 with Mode 1 or Mode 3 throughout the week. What types of hyperpigmentation does it help with? The mask can help with a range of hyperpigmentation types: - Sun damage / age spots — one of the most common and responsive concerns for yellow LED - Post-acne marks (PIH) — post-inflammatory hyperpigmentation left behind after breakouts - Uneven skin tone and dullness — overall tone improvements typically noticed first - Hormonal pigmentation (melasma) — LED therapy can support management but results may be slower and more variable for melasma specifically; consistency is particularly important Does it work the same on darker skin tones? Yes. LED light therapy is not affected by melanin levels in the skin — the wavelengths work at a cellular level regardless of skin tone. The mask is equally effective across all skin tones, and many customers with deeper complexions specifically use Mode 5 to address hyperpigmentation and uneven tone. When will I see results? Results depend on the type and depth of pigmentation and how consistently you use the mask: - 2–4 weeks: Early improvements in overall skin brightness and dullness - 4–8 weeks: Noticeable fading of surface-level dark spots with consistent use - 8–12 weeks and beyond: More significant and sustained improvement in tone evenness Daily use gives the best results. If daily isn't possible, 3–5 sessions per week is still highly effective. Consistency over time is what drives results with LED therapy — it is a cumulative treatment, not an instant fix.

Can the mask help with anti-aging, wrinkles, and sagging skin?

Can the mask help with anti-aging, wrinkles, and sagging skin? Yes — anti-aging is one of the primary purposes the CHOUOHC Radiance LED Mask was designed for. Red and near-infrared light, which feature prominently across multiple modes, are among the most well-researched wavelengths in skincare for their ability to stimulate collagen and improve skin firmness over time. Why LED light therapy works for aging skin As skin ages, collagen and elastin production naturally slows down. This leads to the visible signs most people want to address — fine lines, deeper wrinkles, loss of firmness, sagging along the jaw and neck, and a general loss of skin density. Red LED light penetrates into the dermis, where collagen and elastin are produced. It stimulates fibroblast activity — the cells responsible for producing these structural proteins — encouraging the skin to rebuild what it gradually loses with age. Near-infrared (NIR) light penetrates even deeper, amplifying this collagen-stimulating effect and supporting tissue repair at a level that visible light alone cannot reach. Yellow LED works at the epidermal level to promote cell turnover and renewal, helping the skin shed older, duller cells and replace them with fresher ones — improving overall texture and radiance. Together these wavelengths address aging from multiple depths simultaneously, which is what makes the mask particularly effective as an anti-aging tool. Which modes to use Mode 1 — 20 minutes (recommended for evenings) The flagship anti-aging mode. Runs through three phases — red, blue, then red again — with near-infrared running throughout. Designed specifically for overall skin tightening, pore refinement, and sagging improvement. Ideal as a nightly treatment. Mode 3 — 20 minutes (deeper collagen focus) A more targeted collagen-stimulation mode using red, yellow, and near-infrared. Best for those with more pronounced wrinkles and sagging who want to go deeper. A great companion to Mode 1 — use one some nights and the other on alternating nights. Neck Mode — 20 minutes Uses red and near-infrared specifically targeted at the neck. The neck is one of the first areas to show signs of aging and is often overlooked. If neck wrinkles and sagging are a concern, this is essential. Suggested weekly rotation for anti-aging: - Evenings: alternate between Mode 1 and Mode 3 - Add Neck Mode as part of the same session whenever possible Does it work for mature skin? Yes — LED light therapy is effective across all ages. In fact, mature skin often responds particularly well because the fibroblasts are still capable of producing collagen when properly stimulated — they simply need the signal that LED light provides. There is no upper age limit for benefit. When will I see results? Anti-aging results from LED therapy are cumulative and build over consistent use: - 2–4 weeks: Improved skin texture, brightness, and a more rested appearance - 4–8 weeks: Noticeable improvement in skin firmness and fine line appearance - 8–12 weeks and beyond: More significant changes to deeper wrinkles, sagging, and skin density Daily use gives the best results. 3–5 sessions per week is realistic and still highly effective. Think of it like skincare exercise — the benefits compound the more consistently you show up.

Can the mask help with acne and breakouts?

Can the mask help with acne and breakouts? Yes. The CHOUOHC Radiance LED Mask has a dedicated acne mode, and LED light therapy — particularly blue light — is one of the most well-established non-invasive treatments for acne-prone skin. Why LED light therapy works for acne Acne is primarily caused by the overproduction of sebum, clogged pores, and the proliferation of Cutibacterium acnes (acne bacteria) and other bacteria beneath the skin's surface. Inflammation driven by this bacterial activity is what turns a blocked pore into a visible, painful breakout. Blue LED light has a natural antibacterial effect — it targets and destroys acne-causing bacteria at the skin's surface without damaging surrounding tissue. It also helps calm the inflammation that makes breakouts more severe and longer-lasting. Red LED complements this by reducing inflammation deeper in the skin and supporting the healing process — helping existing breakouts resolve faster and reducing post-acne redness. Yellow LED assists with skin cell turnover and helps address the uneven tone and marks that breakouts leave behind. Which mode to use Mode 6 — 15 minutes is the dedicated acne mode. It uses red, yellow, blue, and near-infrared LEDs in combination to target bacterial activity, calm inflammation, and begin the repair process in a single session. For ongoing acne management, Mode 6 is your primary mode. You can also rotate it with Mode 4 (25 minutes, targets sebum production and pore congestion) to address the root cause of breakouts alongside the active ones. Suggested approach for acne-prone skin: - Active breakouts: Mode 6 as your primary daily mode - Between breakouts / prevention: alternate Mode 6 with Mode 4 - If post-acne marks are also a concern: introduce Mode 5 into your rotation (brightening, dark spots) Is it safe to use on active breakouts? Yes — unlike many topical treatments or physical exfoliation methods, LED therapy is non-invasive and does not involve touching or disturbing the skin. It is safe to use over active breakouts. Do not use the mask over any open wounds or skin that is broken, but closed breakouts are fine. Can it help with cystic or hormonal acne? LED therapy can help manage cystic and hormonal acne by reducing the bacterial and inflammatory component of breakouts. It is not a hormonal treatment, so it won't address the root hormonal cause — but it can meaningfully reduce the severity, frequency, and healing time of breakouts. Many people with hormonal acne use it as a consistent management tool alongside other treatments. What about acne scars and post-acne marks? For red or pink post-acne marks (post-inflammatory erythema), red light in Mode 1, Mode 3, or Mode 6 helps accelerate healing. For dark post-acne marks (post-inflammatory hyperpigmentation), Mode 5 is the most targeted option — see our dark spots and hyperpigmentation article for more detail. When will I see results? - 1–2 weeks: Reduced redness and inflammation in active breakouts - 2–4 weeks: Fewer new breakouts with consistent use, faster healing of existing ones - 4–8 weeks: Noticeable reduction in breakout frequency and improved overall skin clarity - 8–12 weeks: Sustained improvement in skin tone, texture, and acne frequency Consistency is key — LED therapy works as a cumulative treatment. Daily use is ideal; 3–5 times per week is effective and realistic.

Is the mask used by professionals? How does it compare to clinic treatments?

Is the mask used by professionals? How does it compare to clinic treatments? Used in professional settings The CHOUOHC Radiance LED Mask is used not only by individuals at home but by professionals in medspas, salons, and clinics. It is a professional-grade device that happens to also be designed for comfortable, effective daily home use. If you've had LED therapy in a professional setting before, you'll recognise the technology — the same wavelengths (red, blue, yellow, near-infrared) that practitioners use are built into the Radiance mask. At-home vs. in-clinic LED therapy The core technology is the same. The meaningful difference is frequency and cost. In-clinic LED sessions are typically done once a week or less, partly because of the cost per session and partly because of the logistics of getting to an appointment. A single professional LED session can cost anywhere from $75 to $200+, and most practitioners recommend a course of 6–12 sessions to see results. At-home with the Radiance mask, you can treat your skin daily — or as often as 3–5 times per week — for the cost of the device. Consistent, frequent exposure is what drives LED therapy results. More sessions over time means more cumulative benefit. The advantage of at-home use isn't that it's the same as one clinic session — it's that you can do it every single day, which over weeks and months produces results that are difficult to achieve with weekly clinic appointments alone. The Radiance mask by the numbers - 1,026 LEDs in the face mask - 502 LEDs in the neck piece - 4 wavelengths: red, blue, yellow, near-infrared - 7 modes targeting specific skin concerns - Designed and manufactured in Japan If you're a professional or business interested in the device If you're a medspa, clinic, salon, or skincare professional interested in the CHOUOHC Radiance for professional use, please reach out to us directly at support@chouohctokyo.com and we'll be happy to discuss your needs.

Can men use the mask?

Can men use the mask? Absolutely. The CHOUOHC Radiance LED Mask is designed for all skin types and works equally well for men. LED light therapy is not gender-specific — the wavelengths interact with skin at a cellular level, and skin biology is fundamentally the same regardless of gender. Common skin concerns for men the mask addresses Razor burn and irritation Red light's anti-inflammatory properties make it well suited for calming post-shave irritation and redness. Mode 1 or Mode 3 used after shaving can help reduce inflammation and support faster skin recovery. Ingrown hairs The antibacterial and anti-inflammatory properties of blue light (Mode 6) can help address the inflammation associated with ingrown hairs. Anti-aging Men's skin tends to be thicker and oilier than women's, but it still loses collagen and elastin with age. The same collagen-stimulating effects of red and near-infrared light apply fully — Mode 1 and Mode 3 are just as effective for men targeting firmness, jawline definition, and fine lines. Acne and oily skin Men tend to produce more sebum than women, making oily skin and breakouts a common concern. Mode 4 targets sebum production and enlarged pores; Mode 6 targets acne-causing bacteria and inflammation directly. General skin health and texture Mode 2 (10 minutes, morning) is an easy addition to any morning routine — quick, effective, and a great way to start the day with tighter, more even skin. Does it fit men's faces? The mask is adjustable and designed to fit a range of face shapes and sizes. The head stopper and temples open to accommodate different head sizes. If you have any questions about fit, feel free to reach out at support@chouohctokyo.com.
