What is different about this stage

The prevention decade. Skin still recovers quickly, which makes it the cheapest possible time to build sunscreen and barrier habits.

What sun damage & photoageing looks like here

The cumulative account — mottled tone, freckling, roughness and lines that track exactly where the sun reached.

Ingredients to lean on
