Wavelengths in the 630-850nm range are the most studied for improving décolletage elasticity, hydration, and the appearance of crepiness.
One 2021 clinical study found that daily use of an at-home LED device on the neck for 16 weeks visibly improved elasticity, skin density, and hydration, with no adverse effects.
Devices with a higher concentration of LEDs can shorten treatment times compared to standard treatments that require 10 or more minutes.
A good starting point at home is a 3-minute session repeated 3 to 5 times per week.
Décolletage skin is thinner with fewer oil glands than facial skin, which is why it often needs a dedicated routine rather than facial leftovers.
For crepey chest skin, wavelengths between 630 and 850 nanometers, moving from red into near-infrared, delivered in short, consistent sessions, about three minutes, three to five times weekly, are the combination most supported by current research and dermatology-informed guidance.
Why Décolletage Skin Ages Differently
The décolletage has far fewer sebaceous glands than facial skin, leaving it prone to crepiness. It also experiences collagen loss, tech neck, and sun exposure.
Because this area behaves differently, the décolletage benefits from a dedicated routine built for its unique structure rather than facial skincare leftovers.
Which Wavelengths Help Crepey Chest Skin?
Red, deep red, and near-infrared light (630 to 850 nanometers) are widely studied for helping revive skin cells. They work through photobiomodulation, which supports mitochondrial function and cellular repair.

These depths matter because devices that combine overlapping wavelength ranges can offer more layered skin benefits than tools that rely on a single wavelength alone, since each depth targets a slightly different layer of tissue.
In plain terms, boosting cellular energy production, known as mitochondrial function, helps skin cells repair and renew more efficiently. Over time, that can translate into smoother texture, better hydration, and a firmer feel, the kind of visible change most people actually notice.
Neck & Chest Pro Light Therapy Mask
The Solawave Neck & Chest Pro Light Therapy Mask helps visibly improve chest and neck skin texture and firmness in minutes. It delivers red, deep red, near-infrared, and amber wavelengths simultaneously for layered, efficient coverage.
This mask has 180% more LEDs than the original Solawave neck and chest device, delivering multi-wavelength treatment in a single three-minute session.
Your purchase is fully covered. Every mask comes backed by a 1-year warranty and a 60-day risk-free return period, so you can try your new routine with peace of mind.
How Long Is a Light Therapy Session?
A three-minute session, done three to five times a week, is a recommended starting point for at-home light therapy on clean, dry skin. Higher LED density allows for more consistent coverage. This is why newer devices can shorten sessions compared with standard 10-plus minute treatments.
Always perform a light-sensitivity patch test before your first session. Light therapy is generally not recommended for anyone under 18, pregnant or breastfeeding, or with active cancer, a severe skin condition, photosensitivity, or a recent sunburn.
Cleanse and dry your neck and chest completely so light can reach skin without a barrier of product or moisture.
Position the mask or wand snugly against the décolletage, keeping it flush against skin for even light exposure.
Run one timed three-minute session, letting the built-in timer signal when treatment is complete.
Keep your eyes closed or shielded throughout the entire session to avoid direct light exposure.
Patch testing matters because it lets you confirm how your skin responds to light exposure before committing to a full routine, which helps reduce the chance of irritation on a sensitive area like the chest.
A little upkeep keeps results consistent. Charge the mask fully before first use, wipe the inside with a soft, dry cloth after each session, and store it in a cool, dry place between uses.
Pair Serum and SPF for Best Results
Pairing a hydrating serum and daytime SPF with light therapy sessions locks in moisture. Apply LightBoost Face & Neck Serum, formulated with 5 biomimetic growth factors and 2 neuropeptides, to support skin renewal. Follow with LightBoost Rich Cream, featuring vegan collagen, multi-peptides, and ceramides. This rich cream helps seal in moisture on naturally drier skin. Because the neck and chest receive frequent sun exposure, applying a daytime SPF is a crucial final step to help protect your skin.
Which wavelengths work best for chest skin?
The 630-850nm band, spanning red through near-infrared light, is the most studied range for reviving skin cells. Devices combining these wavelengths offer layered benefits compared to single-wavelength tools.
How long should chest sessions last?
A commonly recommended starting point is 3 minutes per session, done 3 to 5 times weekly, especially with high-LED-density devices designed for full-coverage neck and chest treatment.
Can I use facial masks on chests?
Facial devices are sized and shaped for the face, so a dedicated chest and neck mask is the better fit. It matches the contours of this area, where skin is more delicate, for even coverage.
Is red light safe for the chest?
Light therapy is generally considered non-invasive, and a patch test is recommended before first use. It is best avoided by minors, during pregnancy or breastfeeding, and by those managing cancer, photosensitivity, severe skin conditions, or a fresh sunburn.
When will I see chest results?
Based on clinical studies, one can expect gradual change over weeks of steady sessions, not an instant transformation. Results vary based on the individual, which is why Solawave offers a 60 day money-back guarantee.
What should I apply after sessions?
Following with a hydrating serum, a rich cream, and daytime SPF is recommended to help lock in results and protect your skin.
