Mechanism of Action
Madecassoside
Madecassoside (triterpene glycoside from Centella asiatica) inhibits NF-kappa B nuclear translocation by preventing I-kappa B alpha degradation, suppressing transcription of pro-inflammatory cytokines (TNF-alpha, IL-1beta, IL-6) and COX-2. Activates Nrf2, upregulating antioxidant enzymes (heme oxygenase-1, NQO1, glutathione peroxidase). Stimulates collagen type I synthesis through TGF-beta/Smad3 signaling in fibroblasts, upregulating COL1A1. Promotes keratinocyte migration (wound closure) by enhancing integrin expression and matrix metalloproteinase activity. Inhibits hyaluronidase, preserving skin hyaluronic acid. Reduces VEGF expression, inhibits MMP-1. Comprehensive: anti-inflammatory, antioxidant, pro-collagen, wound-healing. Used in pharmaceutical wound care (Madecassol) and K-beauty. Ideal for post-procedure recovery, retinoid irritation, sensitive skin.
Witch Hazel
Hamamelitannin (a gallotannin) and polyphenols cross-link and precipitate stratum corneum proteins via hydrogen bonding and hydrophobic interactions, temporarily tightening skin surface, reducing pore appearance, creating matte finish by binding sebum. Tannins inhibit 5-lipoxygenase (reducing leukotriene B4) and scavenge reactive oxygen species. Gallic acid, catechins, proanthocyanidins provide antioxidant protection. Hamamelitannin inhibits elastase, potentially protecting elastin. Astringent effect temporary (hours) — does not alter pore size or sebum production long-term. Alcohol-free witch hazel (distillate or hydrosol) preserves benefits; alcohol formulations add drying and barrier-disrupting effects. Polyphenols may have mild vasoconstrictive effects, reducing erythema.

Full Profiles
Madecassoside →
A purified triterpene glycoside from Centella asiatica that is the primary anti-inflammatory and wound-healing compound in the 'cica' family. While Centella asiatica extracts contain a mix of four triterpenes, isolated madecassoside provides the most potent soothing and barrier-repair effects. It is particularly effective for post-procedure recovery, sensitive skin, and skin exposed to environmental stressors like pollution and UV.
Witch Hazel →
An astringent extract from Hamamelis virginiana bark and leaves with anti-inflammatory and antioxidant properties. Traditional uses include treating acne, reducing pore appearance, and soothing irritated skin. However, many commercial witch hazel toners contain high concentrations of alcohol that can dry and damage the skin barrier. Alcohol-free witch hazel is the preferred form for skincare.
