Centella asiatica — or "cica" in the cosmetic world — has become the most beloved soothing ingredient for sensitive, reddened, and irritated skin in recent years. This plant, used for centuries in traditional medicine as a wound healer, is now a proven active in modern dermatology for barrier repair and inflammation control. In this guide, we, from a pharmacist's perspective, explore what cica is, how it works on the skin, and for whom it is ideal.
What is Centella Asiatica (Cica)?
Centella asiatica is a plant that grows in the tropical regions of Asia and is also known as "tiger grass." Its power in skincare comes from four main active molecules: asiaticoside, madecassoside, and their corresponding forms asiatic acid and madecassic acid. These pentacyclic triterpenes are the ingredients behind the soothing and restorative effects of "cica" products.
How Does it Work on the Skin?
Centella asiatica's actives work in multiple ways. It suppresses inflammatory signaling pathways, reducing redness and irritation; it stimulates fibroblasts, supporting collagen synthesis; it has an antioxidant effect, reducing free radical damage, and contributes to different stages of wound healing. Therefore, cica is not just a "soothing" ingredient, but also a barrier-repairing and regenerating component. We explained why the skin barrier is so important in detail in our skin barrier guide.
Effects on the Skin
| Effect | Description |
|---|---|
| Soothing and redness reduction | Rapidly calms irritation and erythema by suppressing pro-inflammatory signals. |
| Barrier repair | Supports the recovery of damaged skin; increases sensitivity threshold. |
| Collagen synthesis support | Stimulates fibroblasts, contributing to tissue repair and improved appearance of scars. |
| Antioxidant protection | Supports the skin against free radicals, reducing the effects of environmental stress. |
Scientific Evidence
A comprehensive review on asiaticoside and madecassoside summarizes that these two triterpene glycosides demonstrate wound healing, anti-inflammatory, antioxidant, and anti-allergic effects; furthermore, they are cosmetically valuable for skin hydration, collagen synthesis, UV protection, and improving the appearance of scars. Another review cited Centella asiatica among the most effective herbal options for burn wound healing, identifying madecassoside and asiaticoside as the main active components. These data form the scientific basis for cica's popularity, especially in sensitized and post-procedure skin.
Who Should Use It, How to Use It?
Cica-containing products are ideal for sensitive, redness-prone skin, those with a history of rosacea and eczema; individuals experiencing irritation from retinol/acid use, and skin in the recovery period after procedures (microneedling, peeling, laser). Cica serum or cream can be used in the soothing step of the routine; after serum, with a moisturizer, or instead of it. We discussed post-procedure care in our post-laser guide, and sensitive skin routines in our sensitive skin article. Cica is a gentle ingredient; it is well-tolerated by most skin types.

Frequently Asked Questions
Can cica be used with retinol?
Yes. Cica pairs very well with retinol because it soothes the redness and irritation caused by retinol. Using a cica-containing cream as a moisturizer on retinol nights helps with tolerance.
Is cica only for sensitive skin?
No. While cica is prominent for sensitive skin, its antioxidant and collagen-supporting effects make it suitable for all skin types. Oily skin can opt for light, water-based cica serums; dry skin can prefer richer cica creams.
When can I use cica after a procedure?
After procedures like microneedling, peeling, or laser, cica-containing products are often recommended from the first few days due to their soothing and repairing effects. However, it is always best to follow the guidance of your specialist who performed the procedure.
Do I need sunscreen when using cica?
Cica does not cause photosensitivity; however, as with any skincare routine, broad-spectrum sunscreen use during the day is essential. Especially for post-procedure and sensitive skin, sun protection supports healing.
Conclusion
Centella asiatica (cica) is a versatile active that combines its traditional use with modern scientific evidence, offering soothing and barrier-repairing benefits.
