Centella asiatica (cica): the calming barrier-repair herb

6 min readingredient

Centella asiatica (also called gotu kola, tiger grass, Indian pennywort, and the K-beauty term 'cica') is a small herb that has been used in traditional Asian medicine for centuries for wound healing and skin repair. K-beauty popularised it in Western skincare in the late 2010s, and it has become one of the most-cited ingredients for sensitive, reactive, and barrier-compromised skin.

What it does, in one line

What centella does

Centella asiatica contains several active compounds, principally madecassic acid, asiatic acid, madecassoside, and asiaticoside. These compounds together stimulate collagen synthesis, modulate inflammation, and accelerate wound healing in animal and human studies.

The visible skincare effects include: reduced redness and reactivity within 2-4 weeks of consistent use, accelerated healing of acne scars and minor wounds, calming of post-laser or post-peel redness, and visible barrier strengthening when used alongside ceramide-rich moisturisers.

The brand Dr Jart+ (Korea) built its Cicapair line around centella and remains one of the most-cited K-beauty centella entry points. La Roche-Posay's Cicaplast Baume B5 (France) uses centella alongside other repair ingredients and is heavily prescribed by dermatologists post-procedure.

How to use centella in your routine

Apply morning, evening, or both. Centella formulations come as serums, ampoules, sleeping masks, and barrier creams. The most-effective placement is as a layer between active treatments (retinol, acids) and the final moisturiser, where it can buffer irritation.

Pair particularly well with: retinol (to buffer irritation), barrier-repair ceramides (for compounded effect), and niacinamide (anti-inflammatory stacking). Avoid combining with strong acids in the same routine; let centella have its own slot.

For post-procedure use (after laser, peel, microneedling, or extractions), centella is one of the most-recommended ingredients for the first 5-7 days. Most dermatologists provide or recommend a centella-based barrier cream for this window.

The K-beauty cica trend

The K-beauty 'cica' trend that broke into Western beauty around 2018 specifically positioned centella products for skin recovery from over-exfoliation and routine fatigue. The 'cica trend' was downstream of the 2016-2018 Western over-acid-exfoliation phase that produced widespread barrier damage, and centella offered a gentle alternative.

The trend has matured into a stable category. Centella-based products are now standard in dermatology-influenced skincare across markets. The K-beauty origin remains visible in product names and packaging, but the ingredient itself has been adopted globally.
