Solawave Neck & Chest Pro Light Therapy Mask is an FDA-cleared at-home LED mask designed specifically for the décolletage — the neck and chest area where signs of aging often appear first and that face-only treatments miss. Features 320 LEDs across 4 scientifically-proven wavelengths: red light (630nm) for mid-dermal collagen support, near-infrared light (830nm) reaching the deepest skin layers, deep red light (660nm) for mid-to-deep dermal renewal, and amber light (605nm) for surface tone evenness and visible redness reduction. Edge-to-edge coverage targets the visible signs of aging the face-only LED masks can't reach: neck and chest wrinkles, sagging, dullness, redness, texture irregularities, and uneven skin tone. 3-minute treatments used 3-5 times weekly on clean skin. Pair with Solawave LightBoost Face & Neck Serum applied before and LightBoost Face & Neck Rich Cream applied after to optimize results — the LightBoost ingredient combined with light therapy has been shown to produce significantly better outcomes than light therapy alone in studies. Flexible silicone form contours to the décolletage. Not recommended during pregnancy, for individuals under 18, those with active skin cancer, those with Fitzpatrick Skin Type V or VI without dermatologist consultation, those with seizure or photosensitivity conditions, or those taking light-sensitizing medications. Rechargeable. 1-year warranty, 60-day money-back guarantee.
