Tinted sunscreens offer superior protection against visible light (VL) photodamage compared to non-tinted options. However, limited shade diversity and lack of standardized guidelines hinder their widespread adoption for skin protection.
Area of Science:
- Dermatology
- Photoprotection
- Cosmetic Science
Background:
- Visible light (VL) contributes to skin photodamage, including hyperpigmentation and erythema.
- Tinted sunscreens are increasingly recognized for mitigating VL-induced effects.
- Challenges persist in the adoption and utilization of tinted sunscreen formulations.
Purpose of the Study:
- To review recent clinical evidence on the efficacy of tinted sunscreens.
- To explore obstacles limiting the recognition and utilization of tinted sunscreens.
- To update the understanding of tinted sunscreens in visible light photoprotection.
Main Methods:
- Comprehensive literature search conducted across major databases (MEDLINE, PubMed, Cochrane, Web of Science).
- Keywords included "visible light," "sunscreens," and "tinted sunscreen."
- 67 relevant articles were selected for detailed review from an initial retrieval of 89.
Main Results:
- Tinted sunscreens demonstrate superior efficacy over non-tinted products in protecting against visible light-induced photodamage.
- Tinted sunscreens are effective in managing melasma relapse.
- Photoprotection extends beyond ultraviolet (UV) radiation to include visible light spectrum.
Conclusions:
- Tinted sunscreens offer enhanced photoprotection against visible light.
- Barriers to adoption include lack of standardized guidelines, unified evaluation metrics, and inadequate shade diversity.
- Future research should prioritize expanding shade ranges and establishing comprehensive evaluation standards.
