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.

Below is a breakdown of some of my favorites:

This Ultra-Pure Quintessential Serum is designed to block glycation. Glycation is the break down in 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. 

Apply a few drops of the serum to clean skin in the morning and evening, gently massaging the product in.

Sérum Collagène Natif is an intense treatment to restore and improve volume, tone strength and plumpness. It is recommended for dehydrated skin and specifically formulated with biological collagen extracts. The skin will be left hydrated, silky soft and glowing. 

Apply 0.5ml (10 drops) of Serum Collagène Natif on clean skin over the whole face, neck, and cleavage in a light ascending massage until the product has been completely absorbed. Serum Collagène Natif can be combined with all the other biological Quintessential Serums.

Serum Colostrum is intended for severely dry, or damaged skin. With intense moisturizing properties, this serum is the saving grace for damaged skin. Colostrum extracts help to prevent future drying, and repair dehydrated skin. This serum is intended for use after exposure to sun or harsh conditions, restoring comfort and plumpness to the skin. 

To apply, put 0.5 ml (10 drops) on the face, skin and cleavage and allow time to absorb. Serum Colostrum can be combined with all other Quintessential Serums. 

For those who struggle with acne prone and oily skin, the Serum Complexe Iribiol is the answer. The combination of salicylic and zinc helps to clean the skin while simultaneously healing the epidermis. Salicylic acid works to clear out dead skin and excess oil from your pores, targeting the acne causing buildup. Complexe Iribiol can be used on congested areas of the skin with excess oil to treat acne and imperfections. 

To use, apply 0.5 ml (10 drops) onto the face and neck, focusing on the T-Zone. Leave the product until it is fully absorbed into the skin. 

Serum Dermopore is a rebalancing serum that is good for skin with oily conditions. Containing java tea, it works to reduce sebum secretion, tighten pores, refine skin irregularities and purify the epidermis. Pores play a vital role in the physiology of the skin, allowing it to “breathe”, but it is essential to prevent and treat dilated pores before inflammation sets in and acne appears. This serum is, therefore, a care product for daily prevention for seborrheic skin types, which are prone to acne and skin imperfections. Your skin will be left perfectly matte, more balanced and even.

Extract 1 ml (20 drops) of Serum Dermopore. On clean skin, apply the serum to the whole face, neck and décolleté by lightly massaging upwards until complete absorption of the product. Apply well on the median zone which is generally denser in sebaceous glands.

Early signs of dehydration in the skin can be stopped with the Serum Extraits Tissulaires, which contains cellular oligopeptides. These peptides work to moisturize the upper layers of the skin, where the first signs of drying appear. This serum works to hydrate and strengthen the skin and is suitable for all skin conditions. It can be combined with other Quintessential Serums. 

To use, apply 0.5 lm (10 drops) to clean skin on the face and neck, allowing time to absorb. 

Serum Placenta is an intensive repairing serum intended to brighten the complexion. Containing placental biostimulant protein extracts, it works to strengthen and rebuild the epidermis. With healing, strengthening, and restorative properties, this serum is great for those with acne scarring. 

To use, apply 0.5 ml (10 drops) to the face and neck, or directly to imperfections. The intensive treatment is effective enough for targeted spot treatment.

This serum is an advanced, intensive treatment intended to give the skin an overall boost. It is recommended for dull or sagging skin conditions. The formula contains plant extracts of rye and hazelnut oligopeptides, which help to firm and tone the muscles supporting the skin. It  was formulated to regenerate the skin’s fibrous network which supports its structure. This intense serum is formulated for regular use or special events where you want to look your best. 

To use, apply 10 ml (20 drops) to perfectly clean skin, allowing it time to absorb.
