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]. ---

Tea tree oil
Can I use 100% pure tea tree oil directly on my skin?
No. Applying 100% pure tea tree oil directly to the skin is highly discouraged by dermatologists and regulators. It is a concentrated essential oil that can cause severe irritation, burning, peeling, and trigger permanent contact sensitization (allergy). Always dilute it in a carrier oil (such as jojoba or rosehip) to a concentration of 1% to 5% before topical use, or use a pre-formulated cosmetic product.
Why does my tea tree oil smell different over time, and is it still safe?
If your tea tree oil has developed a strong, sour, or rancid odor, or has turned viscous, it has likely oxidized. When exposed to light, heat, and air, monoterpenes in the oil degrade into highly sensitizing peroxides and epoxides. Using oxidized tea tree oil carries an extremely high risk of causing severe contact allergy and skin rashes. It should be discarded immediately. ---
