Notes on Biologique Recherche Quintessential Serums
I’ve used Biologique Recherche Quintessential Serums on my own skin for over 20 years now, and when it comes to a truly bespoke approach, they remain unmatched. These little workhorses are formulated as raw, small-molecule extracts to do the heavy lifting at a cellular level. The serums are cocktailed to create a targeted treatment to correct specific concerns and imbalances whilst also repairing damage as it occurs, allowing for a hyper-customized solution in real time. Because they are pure concentrates the serums tackle issues at their source, whether that be dehydration, fine lines, loss of structural integrity, uneven tone, or persistent congestion. Pick your poison 🧪
To Hydrate
Sérum Amniotique VG: A primary source of hydration that reaches deep into the epidermis to replenish moisture. Best for: Dehydrated and stressed skin.
Sérum Colostrum VG: An intensive lipid-restoring “emergency” treatment that repairs the skin barrier. Best for: Very dry, depleted, or devitalized skin.
Sérum Extraits Tissulaires: A foundational moisture-balancer that prevents dehydration and maintains a dewy glow. Best for: Oily, sebaceous, and blemish-prone skin lacking moisture.
To Correct
Sérum Iso-Placenta: A specialist for skin repair that focuses on regenerating damaged tissue and fading post-breakout marks. Best for: Blemish-prone skin with traces of acne or scarring.
Complexe Iribiol: A balancing act that regulates sebum and purifies the complexion. Best for: Seborrheic, acne-prone, or congested skin.
Sérum Dermopore: Specifically targets dilated pores to refine texture and regulate shine for a matte finish. Best for: Seborrheic or coarse-textured skin with visible pores.
Sérum Oligo-Protéines Marines: A shot of energy that oxygenates cells to unify the complexion and target dark circles. Best for: Dull, lackluster, or “smoker’s” skin.
Sérum Liposmose: A targeted anti-puffiness treatment for the eye contour. It reduces water retention and strengthens the skin’s resistance to external stress. Best for: Congested or heavy under-eyes.
