3 key assets

Hyaluronic Acid

Attracts and retains up to 1000 times its weight in water. Deeply plumps the skin and maintains hydrating comfort all day long.

Gotu Kola

Repairs and strengthens the skin barrier. Helps skin better resist external aggressions and maintains long-lasting comfort.

Dragon's Blood

Soothes, repairs and promotes natural skin regeneration. Helps strengthen the skin barrier and protects against external aggressions for more comfortable and visibly revitalized skin.

Signature Annaïs Paris
"The first step of your In&Out ritual."

"A sensorial formula, recognized active ingredients, integrated into the In&Out Annaïs Paris vision, to support dehydrated skin, both on the surface and deep down."

Reviews that speak for themselves

Aliénore P.
23 years old, France

My skin is visibly more hydrated after just the first few applications. No more tightness when I wake up. I highly recommend it.

Claire U.
29 years old, France

Lightweight texture, absorbs immediately. My skin is soft and plumped by the next morning.

Laure B.
26 years old, France

No more tightness since I started using this serum. My skin feels comfortable all day long without any heaviness.

Why combine the three products?


The serum intensely hydrates the skin, the cream helps preserve this hydration, and the supplement works from within. Together, they form a complete In&Out routine for lasting hydration.
