A real shock treatment to boost hydration, Sérum Yall~02 contains ultra-high doses of hyaluronic acid and antioxidant plant extracts. This intense hydrating treatment provides the amount of moisture skin needs to function properly and feel comfortable. The effect is instant, as the fine lines caused by dehydration are plumped up.

This serum's innovative formulation based on nano-technology and oxygenating vectors provides intensive treatment and instant effects which are prolonged with regular application. This plumping, regenerating elixir is a highly effective anti-aging fluid, rich in Hyaluronic Acid and antioxidant botanical extracts which restructures and protects the epidermis. 

Recommended for skin that is dehydrated and lacking in lipids.

This serum is pricey but so effective for plumping and hydrating the skin, some clients refer to it as "liquid filler". In the summer months you can try this mixed with another finishing serum like Fluide vip02 in place of your moisturizer over your quintessential serum. It's also really nice under Biokiss to plump the lips.


1. Apply 4 to 5 drops of finishing serum to the entire face, eye contour, lips,  neck and décolleté, in the morning and/or at night

2. This product is applied as the final touch of the Biologique Recherche skincare program


For external use only.
