Sérum Yall~O2

Fundamental hydration elixir

Recommended for Skin Instants© that are dehydrated.

Serum Yall~O₂ combines high- and low-molecular-weight hyaluronic acids with a kale-derived concentrate to deliver long-lasting hydration, proven to significantly increase skin moisture for several hours after application. Designed to work both on the surface and within the upper layers of the epidermis, it leaves the skin feeling more supple and visibly plumper. Over time, skin appears softer and more comfortable.

Skin Science:

Hyaluronic acid is an essential molecule naturally found in the skin. Its role is to fill the gap between epidermal cells to plump up the skin and protect it against dehydration. In cosmetics, it comes in various forms, the first type, known as "high molecular weight", stays on the surface of the epidermis and creates a protective film which prevents the water in the skin from evaporating. The second, known as "low molecular weight", takes the form of smaller molecules which penetrate more deeply into the epidermis to help support and maintain the skin’s natural hyaluronic acid reserves.

Application Instructions:

1. Apply to the face, neck and décolleté, in the morning and evening, at the end of your skincare routine or before a foundation.
