Boundaries & caveats

Boundaries and caveats, Centella asiatica compared with Salicylic Acid
Attribute	Centella asiatica	Salicylic Acid
Direct contraindications	Published case reports describe hepatotoxicity (liver injury, including jaundice and granulomatous hepatitis, with one case recurring on re-exposure) following oral ingestion of Centella asiatica as an herbal remedy or dietary supplement; this concern is specifically tied to oral ingestion, not topical cosmetic use, and no report of topical hepatotoxicity was located [S014]. Separately, no published report of photosensitivity or a phototoxic reaction to topical Centella asiatica extract was located in this research -- an explicit absence of evidence, not a demonstration of safety in sun exposure.

Before you start	Documented as a weak sensitizer; may cause allergic contact dermatitis when applied repeatedly to severely compromised or post-procedure skin.	Lipophilic keratolytic active that can cause mild dryness, peeling, or tingling during initial use. Daily broad-spectrum sun protection is recommended.
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 30% professional chemical peel outcomes cannot be expected from low-dose 0.5% daily consumer cleansers or leave-on toners. The lipophilic, follicular-penetrating properties of free Salicylic Acid differ from hydrophilic AHAs like Glycolic Acid, making BHA superior for sebum-clogged pores but less hydrating on surface dry skin. In-vitro antibacterial signals against Cutibacterium acnes do not replace systemic antibiotics in severe nodulocystic acne.

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, 병풀'. 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]. Documented as a weak sensitizer; may cause allergic contact dermatitis when applied repeatedly to severely compromised or post-procedure skin. Documented as a weak sensitizer; may cause allergic contact dermatitis when applied repeatedly to severely compromised or post-procedure skin.

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

**A:** Yes, Centella asiatica, 병풀 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]. --- Documented as a weak sensitizer; may cause allergic contact dermatitis when applied repeatedly to severely compromised or post-procedure skin. Documented as a weak sensitizer; may cause allergic contact dermatitis when applied repeatedly to severely compromised or post-procedure skin.

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

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