Non-ablative fractional laser (NAFL) technology delivers laser energy in a grid of thousands of microscopic columns — called micro-treatment zones — deep into the dermis, while leaving the surrounding skin and the epidermis (outer skin layer) intact. Unlike ablative lasers, which remove the outer skin layer entirely, NAFL treatments require no recovery period because the skin surface is never broken.

The controlled thermal micro-injuries trigger the body's natural wound-healing response — stimulating collagen and elastin production in the treated zones. Over 6–8 weeks, new collagen fibers replace damaged tissue, resulting in improved skin texture, reduced fine lines, and more even skin tone.

OYAY LAB home devices use Non-Ablative Fractional Laser technology at clinically validated wavelengths, delivering the same biological mechanism used in professional dermatology practices — in a safe, Class 1 certified at-home format.

Laser wavelength determines which biological target (chromophore) in the skin absorbs the energy. OYAY LAB devices use four clinically validated wavelengths:

These are not approximations — they are the precise wavelengths documented in peer-reviewed dermatology literature and used in professional clinical settings worldwide.

LED (Light Emitting Diode) devices emit broad, low-intensity light that affects primarily the epidermis (skin's surface layer). They can support surface skin health but do not generate sufficient energy to penetrate the dermis and stimulate meaningful collagen remodeling.

OYAY LAB devices are true laser devices — they emit coherent, focused, high-energy light at a single precise wavelength. This allows energy to be delivered to a targeted depth in the dermis with the intensity required to trigger genuine collagen neogenesis (new collagen formation).

The distinction matters clinically: LED devices are cosmetic; NAFL laser devices like those in the OYAY LAB range produce measurable structural changes in dermal collagen that are detectable by ultrasound imaging in clinical studies.

Dreame Technology is a global leader in precision consumer device engineering, known for sub-millimeter motor accuracy and advanced sensor integration. OYAY LAB's partnership with Dreame brings that hardware engineering standard into aesthetic devices — ensuring the multi-dimensional skin contact sensors, optical path alignment, and energy delivery systems meet tolerances normally reserved for medical instruments.

Additionally, OYAY LAB's microprocessor chips are sourced from the same semiconductor supply chain as NVIDIA — enabling real-time fluence calculation and pulse-by-pulse energy calibration that ensures consistent, safe dosing across every treatment session.

Yes. All OYAY LAB home devices are certified to IEC 60825 Class 1 — the highest safety classification under international laser safety standards. Class 1 means the device is safe under all reasonably foreseeable conditions of normal use, including direct viewing of the beam.

In addition to the IEC 60825 Class 1 certification, OYAY LAB home devices incorporate a multi-dimensional skin contact sensor that prevents the laser from firing unless the device is in full, stable contact with skin — and immediately deactivates if contact is lost. This eliminates the risk of accidental exposure to eyes or non-target tissue.

The 360° icy crystal cooling system (Iris Ice Plus) and energy-limiting design across all home devices ensures the epidermis is never over-treated. Five smart zones and three energy levels allow users to match treatment intensity to their skin's individual needs.

OYAY LAB home devices are designed for healthy adults aged 18 and over. The following individuals should consult a qualified dermatologist or physician before use:

• —  Individuals with active skin infections, open wounds, or inflammatory skin conditions (e.g., active eczema, psoriasis, rosacea) in the treatment area
• —  Those currently taking photosensitizing medications (e.g., certain antibiotics, retinoids, or isotretinoin)
• —  Individuals who have undergone ablative laser resurfacing, chemical peels, or dermabrasion within the past 3 months
• —  Pregnant or breastfeeding individuals
• —  Those with a personal or family history of keloid scarring
• —  Individuals with implanted electronic devices (e.g., pacemakers) in or near the treatment area

The Nova acne device includes a Child Safety Mode and First-Usage Safety Procedure. Do not use any OYAY LAB device on skin with tattoos, permanent makeup, or suspicious lesions without first consulting a dermatologist.

IEC 60825 is the international standard published by the International Electrotechnical Commission governing the safety of laser products. Class 1 is the safest laser classification — it indicates that the accessible laser radiation during normal operation is below the level that is known to cause injury under all reasonably foreseeable conditions, including the use of optical instruments.

Achieving Class 1 certification requires engineering controls (such as interlocks, beam limiters, and skin contact sensors) that prevent unsafe exposure — not simply low power output. OYAY LAB home devices achieve Class 1 status through active safety systems, not by limiting therapeutic efficacy.

Laser-stimulated collagen remodeling is a biological process — results appear progressively, not immediately. Most users report the following timeline:

• —  Weeks 1–2: Improved skin hydration and subtle radiance from increased circulation
• —  Weeks 3–4: Visible improvement in skin texture; pores appear tighter
• —  Weeks 6–8: New collagen fibers become structurally significant; fine lines visibly reduced
• —  Month 3+: Cumulative results from continued use; improvements in firmness and tone

Consistency is the key variable. OYAY LAB devices are engineered for regular use — the cumulative benefit of sustained collagen stimulation significantly exceeds what any single treatment can deliver.

Recommended usage frequency varies by device:

• —  Iris Ice Plus (1450nm anti-aging): 2–3 times per week per treatment zone
• —  Dora (1927nm skin lightening): 2–3 times per week; allow 48 hours between sessions on the same zone
• —  RelaxLight (940nm soothing): Daily use is suitable for most users
• —  Nova (acne treatment): 8-second sessions per spot; up to twice daily during active breakouts

Always follow the detailed usage guide included with your device and accessible via the OYAY LAB companion app. The IOT chip in compatible devices tracks your usage history and can provide personalized reminders and session recommendations.

No. OYAY LAB home devices use Non-Ablative Fractional Laser (NAFL) technology, which preserves the skin's surface (epidermis) throughout treatment. Because the outer skin layer is never damaged or removed, there is no wound to heal, no peeling, and no social downtime required.

You may notice slight transient redness in the treatment area for 30–60 minutes after use, particularly at higher energy settings — this is a normal physiological response indicating dermal stimulation and resolves without intervention. Sunscreen application is recommended after daytime treatments.

Yes, with some considerations. Laser treatment temporarily increases skin permeability — meaning active ingredients in topicals applied immediately after treatment may penetrate more deeply than usual. This can be beneficial (enhanced absorption of peptides, hyaluronic acid, and antioxidants) or a sensitivity risk (avoid applying retinoids, AHAs, BHAs, or vitamin C directly after treatment).

Recommended post-treatment routine: Apply a gentle, fragrance-free moisturizer or hyaluronic acid serum immediately after treatment. Wait at least 4 hours before applying active exfoliants or prescription topicals.

Avoid on treatment days: Retinol, retinoids, AHAs (glycolic, lactic acid), BHAs (salicylic acid), benzoyl peroxide, and physical exfoliants in the treatment area.

Many users combine devices — for example, Iris Ice Plus for anti-aging and Nova for acne management. There is no contraindication to using multiple OYAY LAB devices; simply allow 24 hours between treatments on the same skin zone.
