Tiger Grass Is the Korean Skincare Ingredient That Fights Redness

Sourced from regions as far-flung as Madagascar and Asia, centella asiatica—also known as Tiger Grass, Gotu Kola, or Cica—thrives in swampy terrain and shaded, moisture-rich forests. Long used for its hydrating, toning, and reparative qualities, this botanical ingredient has become a cornerstone of modern Korean skincare, and is especially beloved by those with sensitive or reactive skin. Fans say it can be a game-changer when it comes to fighting redness caused by irritation, and some studies even show that it may be an effective ingredient for soothing symptoms of rosacea.

Its therapeutic use dates back centuries: in traditional Chinese and Ayurvedic medicine, fresh leaves were applied to wounds to accelerate repair. Today, the beauty world turns to the ingredient for its calming, fortifying, and barrier-protective effects—just ask Vogue beauty writer Kiana Murden who uses the ingredient in her bedtime skincare routine.

What is centella asiatica?

Centella asiatica is a medicinal herb native to Asia. Its feline-associated nickname comes from the legend that tigers roll in its leaves to help heal their wounds. Rich in vitamins, beta-carotene, fatty acids, and antioxidants, Cica is celebrated for its ability to soothe irritation, support repair, and protect the skin’s barrier. It is also known to stimulate microcirculation—a mechanism that encourages cellular renewal and helps reduce inflammation while boosting hydration.

The key benefits of centella asiatica for skin

Centella asiatica is frequently featured in formulas designed for dry, sensitive, or irritation-prone skin. Its reparative and anti-itch properties can help provide relief in conditions such as rosacea, psoriasis, and eczema, though, of course, it should not replace medical care for chronic or severe concerns. Its anti-inflammatory action also strengthens the epidermis, helping prevent redness and flare-ups. “Several in vitro and in vivo studies have demonstrated the therapeutic potential of Centella asiatica in the treatment of acne, burns, atopic dermatitis, and wounds,” notes a recent study that looked at the pharmacological effects of Centella asiatica on skin diseases.

Beyond soothing, Cica offers visible anti-aging benefits. Its triterpenes support collagen synthesis and neutralize free radicals—two actions that help soften the look of fine lines and maintain a smoother, more resilient complexion. “Research results indicate that it can be used in the treatment of photoaging skin, cellulite and striae,” note a scientific review that looked at its uses in cosmetology.

This means the herb also has a role in body care. Because it enhances circulation and supports collagen production, it can aid in improving skin tone and firmness, and, as the study above notes, is often used in formulations targeting cellulite, where its flavonoid content helps encourage drainage and reduce fluid retention.

How to add centella asiatica to your skincare routine

Centella asiatica’s versatility makes it easy to incorporate into nearly any routine. You’ll find it in cleansers, creams, serums, toners, and facial oils, where it pairs well with synergistic actives such as plant extracts, probiotics, ceramides, vitamins, and niacinamide. Depending on your skin’s needs, Cica can help refine texture, diminish blemishes, calm redness, and keep the skin supple and well-balanced.
