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. Designed to be cocktailed to create a targeted treatment to correct specific concerns and imbalances whilst also repairing damage as it occurs, allowing for a hyper-customised 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 devitalised 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, lacklustre, 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.
To Firm and Sculpt
- Sérum Progeskin: A breakthrough in longevity that targets senescence to defy the signs of aging. Best for: Mature skin or those showing early signs of structural decline.
- Sérum Collagène Originel: The ultimate re-densifier that stimulates four primary types of collagen to "re-anchor" the skin and fill deep wrinkles. Best for: Skin with established fine lines, deep wrinkles, and a loss of density.
- Sérum Elastine: Designed to restore the skin’s natural "snap-back" by reinforcing the structural network. Best for: Skin with fine lines and a loss of elasticity.
- Sérum A-Glyca: The specialist for glycation. Designed to both prevent and reverse the "sugar-crust" that attaches to collagen fibres, causing them to stiffen and snap. Best for: Skin showing signs of premature aging, dullness, or a loss of suppleness.
To truly get the most out of these formulas, I recommend mixing them into a targeted cocktail to address your concerns simultaneously.
The Clarifying Cocktail (Blemish-Prone)
