Core Product Details

10% Glycolic Acid for a Freshly Refined Complexion

COS DE BAHA G Glycolic Acid 10% AHA Serum transforms exfoliation into a polished South Korean skincare ritual. Powered by 10% glycolic acid, this overnight treatment helps lift away accumulated dead skin cells that can leave the complexion looking dull, rough or uneven. As the skin's surface is refined, it appears smoother, brighter and increasingly radiant, making this Korean AHA serum an alluring choice for those seeking visible texture renewal without the physical friction of a facial scrub.

An AHA Exfoliating Ritual for Smoothness & Luminosity

Glycolic acid belongs to the alpha hydroxy acid family and acts as the defining exfoliating ingredient within the formula. COS DE BAHA positions its 10% concentration to support exfoliation and skin renewal while improving the appearance of uneven texture, dullness and visible signs of aging. Used consistently and according to tolerance, it encourages the polished look that makes freshly exfoliated skin so captivating—soft, clear and seemingly illuminated beneath the surface.

Brightness Without the Scrub

Rather than relying on abrasive particles, this Korean chemical exfoliating serum loosens dead surface buildup through AHA exfoliation. This makes it particularly suited to a beauty ritual focused on smooth texture and renewed radiance. Skin that appears lacklustre from accumulated dead cells can gradually reveal a fresher-looking surface, while the serum's fluid consistency allows exfoliation to feel elegant and effortless rather than coarse or cumbersome.

Aloe Vera Softens the Experience of Active Exfoliation

The current manufacturer formula complements glycolic acid with aloe vera leaf extract, giving the exfoliating treatment a soothing and moisturizing dimension. Green tea, elderflower, bitter melon and edelweiss extracts further enrich the formula with botanical skin-conditioning and antioxidant care. It is a thoughtful contrast: a high-performance exfoliating acid surrounded by ingredients selected to make the ritual feel more considered and comfortable.

A Clear, Watery Texture Created for Evening Renewal

COS DE BAHA describes G Serum as having a clear, watery texture that absorbs quickly into the skin. After cleansing and toning in the evening, apply an appropriate amount before moisturizer, allowing the fluid treatment to settle into the complexion. The manufacturer recommends using it two to three nights per week rather than treating it as an unrestricted daily exfoliant, making each application a deliberate moment of resurfacing care.

Respect the Power of a 10% Glycolic Acid Formula

Effective exfoliation deserves thoughtful use. Glycolic acid can increase skin sensitivity to sunlight, so diligent daytime sunscreen is essential while incorporating an AHA treatment into your routine. Patch testing is equally important, particularly for sensitive skin or anyone new to chemical exfoliation. By pairing potency with restraint, this Korean glycolic acid serum becomes less about aggressive peeling and more about the gradual pursuit of smooth, luminous, beautifully refined skin.

An Evening Ritual for Skin That Awakens Looking Renewed

Made in South Korea, COS DE BAHA G Glycolic Acid 10% AHA Serum captures the transformative side of modern K-Beauty: the pleasure of allowing one carefully chosen treatment to quietly refine the complexion while the evening unfolds. Its 10% glycolic acid concentration meets soothing aloe and botanical extracts in a fluid formula dedicated to exfoliation, smoothness and brightness. Used thoughtfully, it turns nighttime skincare into a ritual of renewal, revealing the fresh luminosity that can hide beneath dull surface buildup.
