What it is
A tone-up sun serum.
A fluid SPF50+ PA++++ with ectoin, made to shield reactive skin from UV while subtly evening tone.
Why it works
Defend, don't weigh down.
Broad-spectrum SPF50+ blocks the daylight that drives most visible aging and reactivity; ectoin keeps the barrier hydrated under it. Light enough for daily wear.
How to use
