What is the new sunscreen developed by UCLA?

UCLA researchers developed a new mineral sunscreen using zinc oxide in a unique 'tetrapod' shape, which prevents clumping and eliminates the chalky white appearance on the skin.

How does the new tetrapod sunscreen work?

The tetrapod shape of the zinc oxide particles prevents them from clumping, forming an even, mesh-like network on the skin that provides protection without a visible white cast.

What is the benefit of the new tetrapod sunscreen for skin cancer prevention?

By eliminating the chalky white appearance, the new sunscreen aims to improve cosmetic appeal, encouraging more consistent and widespread use, which could lead to better skin cancer prevention.

UCLA researchers developed a new mineral sunscreen using tetrapod-shaped zinc oxide.

This innovation aims to improve consistent sunscreen use for better skin cancer prevention.

A groundbreaking mineral sunscreen developed at UCLA addresses the persistent problem of a visible white or gray cast on the skin. Traditional mineral sunscreens often leave a chalky film due to the clumping of round zinc oxide particles, which is particularly noticeable on darker skin tones.

Scientists at the UCLA Health Jonsson Comprehensive Cancer Center have engineered a solution by using a patented process to create microscopic, four-armed structures, known as 'tetrapods,' from zinc oxide. This unique shape prevents the particles from packing tightly together.

Instead, the tetrapods form a porous, mesh-like network that spreads evenly across the skin. This structural innovation not only eliminates the undesirable white cast but also maintains strong protection against harmful UV rays, achieving an SPF of 30 in laboratory tests.
