La Rosée founders' tips:

- Remember to apply our Hydrating Serum to your neck and neckline!
Our Hydrating Serum combines two types of hyaluronic acids with high and low molecular weight, for a double action.
Hyaluronic acid with high molecular weight remains on the surface to smooth the skin, and act as a hydrating water reservoir. It forms a non-occlusive film that helps retain water in the cells. Therefore it helps regulate transepidermal water loss.
Hyaluronic acid with low molecular weight penetrates deep into the skin thanks to its small size. It plumps up the epidermis with water and repairs cells.
Organic aloe vera hydrates and soothes the skin. Organic apple extract protects the skin from aging thanks to its antioxidant effect.
It leaves the skin quenched, soft and plumped. Wrinkles are smoothed.
The complexion regains its freshness and radiance!
