Centella asiatica is a small marsh herb native to Asia that has been used for thousands of years across Ayurvedic, Traditional Chinese, and Korean medicine to heal wounds and calm inflammation. When applied to the skin, its active compounds — especially madecassoside and asiaticoside — work directly in the deeper layers of the skin to prompt repair and reduce irritation. It became a global skincare staple largely through Korean beauty culture, where it earned the nickname 'Cica' and is now found in hundreds of barrier-repair and sensitive-skin formulations worldwide.

Centella's triterpenoid compounds stimulate the skin's own collagen-making cells (fibroblasts), helping to rebuild damaged tissue and fill in scars over time. At the same time, they calm the inflammatory signals that cause redness, stinging, and sensitivity, making the skin feel more comfortable quickly. The extract also helps reinforce the skin's outer barrier layer, reducing water loss and making skin more resilient against everyday irritants.

Topical cica products range from lightweight serums and toners suited for oily or combination skin, to rich balms and ointments ideal for very dry, compromised, or post-procedure skin. Sheet masks and ampoules deliver a concentrated short-term soothing hit. Most dermatologists recommend starting with a cream or serum applied twice daily. Standardized pharmaceutical-grade extracts (TECA or TTFCA) are the most clinically validated forms and are used in some medical-grade wound-healing dressings.

• Wound healing and post-procedure skin
• Acne scars and keloids
• Sensitive and reactive skin
• Redness and rosacea-prone skin
• Dry and damaged skin barrier
• Stretch marks
• Eczema and atopic dermatitis
• Sunburn and UV-damaged skin
• Fine lines and early skin aging

• Formation of new stretch marks during pregnancy with early and consistent topical use
• Hypertrophic scarring after minor wounds, burns, or dermatological procedures
• Skin barrier breakdown from repeated exposure to irritants or harsh skincare actives

Centella asiatica is consumed as a leafy herb in parts of Southeast Asia and Sri Lanka — eaten fresh in salads, blended into juices, or added to curries — but the concentrated triterpenoid compounds responsible for topical skin benefits are present at much lower levels in food form than in standardized topical extracts. For skin-focused use, the topical route is what the evidence supports. To support the same skin-repair and anti-inflammatory goals from within, a diet rich in vitamin C (citrus, kiwi, bell peppers), zinc (pumpkin seeds, legumes), omega-3 fatty acids (fatty fish, walnuts, flaxseed), and polyphenols (berries, green tea) provides the building blocks for collagen synthesis, barrier function, and inflammation control. Reducing ultra-processed foods and excess sugar also helps protect skin structure over time. Foods to limit: High-glycemic foods (white bread, sugary snacks) — promote skin inflammation and impair wound healing, Alcohol — impairs skin barrier function and delays tissue repair, Excess omega-6 vegetable oils (refined corn, soybean oil) — can shift the body toward a pro-inflammatory state that counteracts barrier repair.

• Mild contact dermatitis — itching, redness, or rash at application site (uncommon, more likely in those with known plant allergies in the Apiaceae/carrot family)
• Stinging on application to actively broken or very compromised skin
• Rare allergic sensitization with repeated exposure — patch test recommended before widespread use
• Comedogenicity is low, but heavier occlusive cica balms may cause breakouts in very oily or acne-prone skin if used excessively

• Recommended daily: Apply a pea-to-dime-sized amount of centella-containing product (look for madecassoside or asiaticoside in the first half of the ingredient list, or a total centelloid content of 1% or higher for therapeutic effect) to clean skin 1–2 times daily. For wound healing or post-procedure use, apply a thin layer 2–3 times daily until the skin has closed.
• Best time of day: Morning and evening. In the morning, apply before sunscreen. In the evening, apply after any active ingredients (retinoids, acids) as a calming, repairing final layer. For dedicated repair, an evening-only routine focusing on a richer cica cream or balm is effective.
• With or without food: Not applicable — topical use only. Apply to clean, slightly damp skin for better absorption, especially with serums and lighter formulations.
• Time to effect: Redness and soothing: 3–7 days; barrier improvement: 2–4 weeks; scar and texture improvement: 6–12 weeks; stretch mark prevention: benefits accumulate over the full duration of use
• How long to take it: No cycling required — centella is safe for continuous daily use. For scar treatment or stretch mark prevention, commit to at least 8–12 weeks of consistent use before evaluating results. Can be used indefinitely as part of a daily skincare routine.
