Scientists at UCLA have successfully redesigned zinc oxide particles to address one of the most common complaints regarding mineral sunscreens: the visible white cast left on the skin. By modifying the structure of these particles, the team has created a formula that maintains high levels of protection against ultraviolet radiation while remaining virtually transparent upon application.
Improving Accessibility for All Skin Tones
The new SPF 30 formula aims to make sun protection more appealing and effective for a broader demographic. Traditional mineral blockers often appear prominent on darker skin tones, leading to lower compliance with sun safety recommendations. This innovation ensures that the physical barrier benefits of zinc oxide—which is often preferred for sensitive skin—are available without aesthetic drawbacks.
This development represents a significant step forward in dermatological science, potentially increasing the regular use of sunscreen and reducing the long-term risks associated with UV exposure across diverse populations.
