Side by side

Centella asiatica compared with Retinal
Attribute	Centella asiatica	Retinal
INCI name	Centella Asiatica Extract	Retinal
Korean name	병풀 (병풀)	레티날
Gentleness score	Gentle — four of five	Use with care — two of five
Evidence grade	Indicative	Indicative
Routine placement	Hydrate	Treat
Boundary	Anti-wrinkle miracle: While Centella stimulates collagen in vitro and improves scar thickness clinically, it cannot replace medical-grade retinoids or injectables for deep wrinkle reversal. Acne curing: Centella calms active inflammation, but it does not possess salicylic acid's pore-clearing (lipophilic) or benzoyl peroxide's direct antibacterial activity against C. acnes.	The superior conversion kinetics and anti-aging benefits of encapsulated Retinaldehyde cannot be assumed for unencapsulated, free Retinal, which degrades rapidly in the presence of light and oxygen. Clinical efficacy demonstrated in nighttime leave-on creams cannot be directly generalized to wash-off cleansing products, which have a very limited skin contact time. In-vitro antibacterial activity against Cutibacterium acnes cannot be used to make medical, drug-like acne clearance claims on cosmetic packaging under general retail guidelines.

Consider Retinal if…

A vitamin-A derivative one step from active retinoic acid — it visibly firms and smooths, and works faster than retinol.

You want a use with care option.

Deep-dive Q&A

Centella asiatica

Why is Centella asiatica often called 'Cica' or 'Tiger Grass' in skincare?

**A:** The term 'Cica' is a marketing abbreviation derived from 'Centella asiatica'. The historical name 'Tiger Grass' originates from traditional observations in Asia, where wounded tigers were observed rolling in wild Centella asiatica patches to heal their wounds. This botanical folklore has been scientifically validated, as modern research demonstrates that Centella's triterpenoids accelerate cellular repair and wound contraction [S004, S009].

Can I use Centella asiatica if I have extremely sensitive, eczema-prone skin?

**A:** Yes, Centella asiatica is highly recommended for sensitive and eczema-prone skin due to its potent anti-inflammatory and barrier-strengthening properties. However, because raw plant extracts can contain trace botanical impurities that act as weak sensitizers, individuals with severely compromised barriers should perform a patch test on their inner forearm for 3 consecutive days before facial application [S007].

What is the difference between a product with '95% Centella Extract' and '0.2% Madecassoside'?

**A:** This is a common source of confusion in cosmetics. A '95% Centella Extract' usually refers to a bulk raw material where dried Centella is steeped in a solvent (typically water and glycols); the actual active molecule concentration in this extract is often less than 0.1%. Conversely, '0.2% Madecassoside' represents a highly purified, isolated active compound that is standardized and tested at precise therapeutic levels. Purified active markers (like Madecassoside or TECA) are significantly more potent and reliable than bulk crude extracts [S006, S008]. ---

What is the biological mechanism and dermatological evidence for Centella Asiatica Extract in skincare?

Centella Asiatica Extract (Centella Asiatica Extract) functions as a Botanical Extract. Botanical extract rich in asiaticoside, madecassoside, and asiatic acid that dampens IL-1beta and TNF-alpha.
