How it works
Mechanism before marketing.
Controlled exposure studies have found that repeated visible light can produce immediate darkening and delayed tanning, with stronger effects in darker phototypes in some research.
Red and near-infrared light have separate research on collagen and rejuvenation. That does not make red light a proven treatment for pigmentation, and it should not be presented as one without matching evidence.
What controls the exposure
The variables that change the biology.
What the evidence supports
The evidence supports being cautious with visible-light claims for pigmentation. Wavelength, dose, skin tone, condition, and sun exposure all matter.
What we cannot assume
Research has boundaries.
SkynthGoods devices are not presented as treatments for melasma or post-inflammatory hyperpigmentation. A dermatologist can help identify the cause and select evidence-based care.
Practical use
Use the technology thoughtfully.
- Use daily broad-spectrum sun protection; ask a dermatologist whether tinted visible-light protection is appropriate for you.
- Avoid using blue light directly over an area that is prone to pigmentation unless a clinician or the device’s validated instructions support it.
- Seek professional advice for new, changing, persistent, or unexplained dark marks.
Primary and regulatory sources
Read the research.
- Repeated visible-light exposure across skin tones
- 450 nm blue-light pigmentation trial
- Visible-light wavelength contribution study
