Mechanism of Action
Centella Asiatica
The four key triterpenoid saponins—madecassoside, asiaticoside, madecassic acid, and asiatic acid—exert distinct but complementary mechanisms. Madecassoside and asiaticoside are anti-inflammatory: they inhibit NF-κB nuclear translocation and IκB kinase activity, reducing TNF-α, IL-6, and IL-1β production in keratinocytes and dermal cells. Madecassic acid and asiatic acid (the aglycone forms) stimulate type I and III collagen synthesis in fibroblasts by upregulating collagen gene expression and procollagen production. All four compounds promote wound healing by stimulating angiogenesis via VEGF (vascular endothelial growth factor) upregulation, fibroblast proliferation and migration, and extracellular matrix remodeling. Centella extracts also increase superoxide dismutase (SOD) and catalase activity in skin cells, enhancing endogenous antioxidant defense. The triterpenes may modulate TGF-β and Smad signaling. TECA (Titrated Extract of Centella Asiatica) standardizes these actives for consistent clinical efficacy.
Panthenol (Pro-Vitamin B5)
Panthenol (D-pantothenic acid alcohol) penetrates the stratum corneum and is converted to pantothenic acid (vitamin B5) by pantetheinase and alkaline phosphatase enzymes in the skin. Pantothenic acid is a precursor to coenzyme A (CoA), which is required for the synthesis of fatty acids (via acetyl-CoA carboxylase and fatty acid synthase) that form the ceramides, cholesterol, and free fatty acids of the stratum corneum lipid barrier. This supports barrier repair, improves lamellar structure, and reduces transepidermal water loss (TEWL). Panthenol has direct humectant properties—its hydroxyl groups attract and bind water in the stratum corneum. It stimulates fibroblast proliferation and migration, accelerating wound healing and re-epithelialization. Panthenol may also have mild anti-inflammatory effects. As a provitamin, it is stable in formulations and well-tolerated. The Bepanthen/Bepanthol healing creams leverage these mechanisms for wound care and barrier repair.
Risks & Safety
Centella Asiatica
Common
Very well-tolerated. Occasionally mild tingling.
Serious
None documented.
Rare
Allergic contact dermatitis (uncommon). Purified extracts are less likely to cause reactions than crude extracts.
Panthenol (Pro-Vitamin B5)
Common
None — extremely well-tolerated.
Serious
None. One of the safest skincare ingredients available.
Rare
Contact allergy is extremely rare.
Full Profiles
Centella Asiatica →
Also known as Cica, Gotu Kola, or Tiger Grass, Centella Asiatica is an herb used in traditional medicine for wound healing that has become one of the most popular soothing ingredients in Korean and global skincare. Its active compounds (madecassoside, asiaticoside, madecassic acid, asiatic acid) reduce inflammation, stimulate collagen production, and accelerate wound healing. Essential for sensitive and compromised skin.
Panthenol (Pro-Vitamin B5) →
The provitamin form of vitamin B5 (pantothenic acid) that provides deep hydration, barrier repair, and wound healing support. When applied to skin, panthenol is converted to pantothenic acid, which is a component of coenzyme A — essential for fatty acid synthesis and skin barrier function. It is one of the most common ingredients in moisturizers and healing creams, and is the active ingredient in products like Bepanthen/Bepanthol.
