Cos De BAHA Glycolic Acid 10% AHA Serum 30ml (G)

Cos De BAHA Glycolic Acid 10% AHA Serum (G) is a lightweight, fast-absorbing gel serum positioned as a professional-grade chemical exfoliant for normal, oily, and combination skin types seeking smoother texture, brighter tone, and refined pores.

Best used in your PM routine after cleansing and toning, applied before moisturizer. Because glycolic acid increases sun sensitivity, this serum is strictly an evening step — always follow the next morning with SPF.

At its core is Glycolic Acid at a clinically active 10% concentration, the smallest-molecule AHA for deep exfoliation and collagen support. Arginine, an amino acid, pairs with glycolic acid to create a time-release effect that softens irritation while boosting collagen and moisture retention. Propanediol (from non-GMO corn) enhances ingredient absorption and adds emollient softness. Botanical extracts — Witch Hazel, Rosemary, Eucalyptus, and Thyme — deliver antioxidant protection and help regulate sebum.

• Exfoliates dead skin cells and accelerates cell turnover to reveal a visibly smoother, more radiant complexion.
• Fades hyperpigmentation, post-acne marks, sun spots, and uneven tone with consistent use.
• Supports collagen production to soften the appearance of fine lines and improve skin elasticity.
• Unclogs pores and controls excess sebum, reducing blackheads and breakout frequency over time.

How to Use: After cleansing and applying a hydrating toner, dispense a moderate amount of serum and gently massage onto face and neck on dry skin. Allow full absorption before sealing with moisturizer. Begin with 2–3 evenings per week, increasing frequency gradually as tolerance builds. Patch test behind the ear before first use, as sensitivity to glycolic acid varies. Always apply SPF the following morning.
