Biologique Recherche and I agree completely on the importance of customization. No two skins are alike, and their conditions can change daily depending on many factors including climate, diet, health, age, and lifestyle. Skin Serums are a vital step in our daily skincare routines. They contain the most potent form of active ingredients with the lowest molecular weights, so that they can penetrate the skin more easily and are ale to treat specific skin conditions.  

The Biologique Recherche Quintessential Serums are the purest formulations in the  Biologique Recherche  range. They are designed to treat a variety of skin imbalances including dehydration, excess sebum, fine lines, elasticity, and devitalized skin, while penetrating the epidermis rapidly and efficiently, creating outstanding and powerful results. They are water-based and the main active ingredients are amino acids or short peptides and a bare minimum of preservatives. 

Below is a breakdown of some of my favorites:

Serum A-Glyca

This Ultra-Pure Quintessential Serum is designed to block glycation. Glycation is the breakdown of collagen and elastin in the skin as a reaction to excess sugar in the body. Serum A-Glyca works like a magnet to the extra sugars. Undigested sugars can cause fragility of collagen which results in fine lines and wrinkles. Two months of continued use of this serum can reverse up to two years of glycation.  

Serum A-Glyca Benefits Include: 

• Acts against the phenomenon of glycation

   

• Protects proteins within the skin’s structure

   

• Reduces seep lines and wrinkles

   

• Reduces signs of tiredness on the face

   

• Contributes to the skin’s firmness

   

• Brings radiance to the complexion

   

How to Use 

Take a few drops of the Serum A-Glyca. Onto clean skin, apply the serum morning and night over the entire face, neck and décolleté using gentle ascending movements until the complete absorption of the product.
