Why Centella Asiatica Is K-Beauty's Favorite Ingredient
Centella asiatica — known as cica, tiger grass, or gotu kola — is arguably the most important ingredient in Korean skincare. Used in traditional Asian medicine for centuries to heal wounds, centella has been validated by modern dermatological research for its powerful anti-inflammatory, barrier-repairing, and collagen-stimulating properties.
Its four key active compounds — madecassoside, asiaticoside, madecassic acid, and asiatic acid (collectively called the TECA complex) — work synergistically to calm redness, accelerate skin healing, and strengthen the moisture barrier. This makes centella asiatica products ideal for anyone with sensitive, irritated, or acne-prone skin.
Centella for Acne Scars and Post-Inflammatory Hyperpigmentation
One of centella's most valuable properties is its ability to regulate collagen synthesis. This means it helps normalize scar tissue formation, reducing the likelihood of raised or discolored scars after breakouts. Studies show that madecassoside specifically inhibits excess collagen deposition while promoting healthy skin regeneration — making it uniquely effective for both preventing and fading acne scars.
