Biologique Recherche and I see eye to eye on the importance of customization.  No two skins are alike, and our own skin’s conditions can change daily depending on many factors including climate, diet, health, age, and lifestyle.  I believe that serums are a vital step in our daily skincare routines, they should be used after toning and before moisturizing. 

The Quintessential Serums are the purest formulations in the Biologique Recherche range. Their only active ingredients are amino acids or short peptides and a bare minimum of preservatives. They can be used alone or you can ‘cocktail’ 3-4 of them at a time to treat each unique skin. To extract the product, squeeze the number of drops from the neck of the dropper onto the palm of the hand.
