Sérum Bio-Exfoliant Ultra-Clarifiant 4% Acide Glycolique

A biotech-driven overnight exfoliating serum formulated to resurface gently while preserving barrier integrity.

Powered by 4% glycolic acid, renewal-supporting peptides and antioxidant protection, it helps refine texture, improve tone clarity and maintain skin comfort during active exfoliation. Nutrient-rich oils and humectants replenish hydration to prevent the dryness commonly associated with acids.

Dermatologically tested · Non-irritant · Alcohol-free · Fragrance-free · Silicone-free · Paraben-free · Vegan

Ideal for dull or uneven tone, visible pores, rough or textured skin, early fine lines and post-blemish marks. Suitable for combination, breakout-prone or mildly sensitive skin that tolerates low-percentage AHAs. Not recommended for compromised, highly reactive or freshly treated skin until the barrier has stabilised.

Size: 50 ml

• Controlled exfoliation — 4% glycolic acid helps dissolve surface cell build-up to smooth and clarify.
• Visible brightness — promotes a fresher, more even-looking complexion.
• Renewal support — biomimetic peptides help maintain firmness and structural integrity during resurfacing.
• Barrier comfort — prickly pear and argan oils replenish essential lipids to reduce dryness and tightness.
• Hydration balance — glycerin and propanediol attract moisture to support suppleness post-exfoliation.
• Antioxidant protection — vitamin E and botanical extracts help defend against oxidative stress associated with renewal.

• 4% Glycolic Acid — the smallest AHA molecule; gently loosens the bonds between dull surface cells to smooth texture, refine the look of pores and brighten uneven tone.
• Myristoyl Tripeptide-31 — supports surface renewal and improves the look of early fine lines without retinoid-type irritation.
• Myristoyl Tetrapeptide-6 — improves firmness and elasticity by supporting the skin's natural repair mechanisms.
• Myristoyl Tetrapeptide-34 — helps calm visible redness and protect against environmental stress.
• Palmitoyl Pentapeptide-4 — a signal peptide that supports collagen pathways, improving smoothness and visible firmness.
• Prickly Pear & Argan Oils — replenish lipids and reinforce the barrier to reduce tightness during exfoliation.
• Glycerin & Propanediol — humectants that draw moisture into the skin and support hydration after resurfacing.
• Clary Sage Extract (Salvia Sclarea) — a soothing botanical that helps reduce visible redness and rebalance stressed skin.
• Vitamin E Acetate — an antioxidant that helps neutralise oxidative stress associated with exfoliation.

Surface dullness and congestion occur when dead cells accumulate and renewal slows. This serum accelerates desquamation using a calibrated 4% glycolic acid concentration, loosening surface cell bonds to promote fresher turnover.

Peptides support the structural proteins involved in firmness, helping maintain resilience during exfoliation. Humectants restore hydration to newly revealed cells, while omega-rich botanical oils reinforce the lipid barrier to minimise irritation. Antioxidants help counteract the oxidative stress triggered during active resurfacing.

The result is renewed skin clarity without compromising comfort.
