Two-Dimensional TiO2 Ultraviolet Filters for Sunscreens (IMAGE)
Caption
- Two-dimensional (2D) TiO2 was developed with > 99% visible light transmittance for non-whitening UV protection, outperforming conventional 0D TiO2 in aesthetics while matching UV-blocking efficacy.
- 2D TiO2 achieves ultralow skin penetration and 90% reduced reactive oxygen species generation versus 0D TiO2, eliminating photocatalytic toxicity and DNA damage risks.
- 2D TiO2 enabled tunable UVA/UVB coverage via metal doping without compromising visible light transmittance, ensuring Scientific Committee on Consumer Safety compliance and biocompatibility.
- We integrated high UV protection, natural appearance, and photoinertness into a single material, redefining aesthetic-safe sunscreen design through 2D structural innovation.
