Side by side

Centella asiatica compared with Spicules
Attribute	Centella asiatica	Spicules
INCI name	Centella Asiatica Extract	Hydrolyzed Sponge
Korean name	병풀 (병풀)	스피큘
Gentleness score	Gentle — four of five	Gentle — four of five
Evidence grade	Indicative	Indicative
Routine placement	Hydrate	Micro-channel
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 73.4% dermal absorption and penetration benefits demonstrated with 200-320 micrometer spicules cannot be assumed for lower-grade or completely broken sponge powders, which lack intact needle geometry. The micro-channel delivery advantages shown in leave-on gel or cream formulations cannot be translated to wash-off foaming cleansers, which are quickly rinsed off before penetration can occur. Topical micro-needle application cannot be assumed to replace or replicate the depth of clinical microneedling procedures, which reach depths of up to 2.0 mm into the dermis.

Consider Spicules if…

Tiny mineral micro-needles that create temporary channels in the skin to help other active ingredients penetrate deeper — best paired with, not used alone.

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.
