What's actually doing the work
Niacinamide
Vitamin B3 / Nicotinamide
Vitamin
The most versatile and universally tolerated skincare active. Inhibits melanin transfer (fading dark spots), reduces sebum by up to 68%, strengthens the skin barrier via ceramide synthesis, calms inflammatory pathways to reduce redness, and visibly minimises pores over 4–8 weeks. Works at any pH and pairs with virtually every other active.
Centella Asiatica
Cica / Gotu Kola / Tiger Grass
Botanical
One of the most clinically validated plant-based actives. Rich in triterpenoid saponins (asiaticoside, madecassoside, asiatic acid) with wound-healing, collagen-stimulating, anti-inflammatory and antioxidant effects. Asiaticoside stimulates collagen I and III; madecassoside shown efficacious for atopic dermatitis in RCTs.
Zinc
Zinc PCA / Zinc Oxide / Sebum Regulator
Mineral
Topical zinc PCA regulates sebum via 5-alpha reductase inhibition, kills C. acnes, reduces inflammation, and accelerates wound healing. Zinc oxide in SPF provides broad-spectrum UV protection. Orally, zinc deficiency is linked to acne severity — supplementation at 25–45mg/day shows clinical efficacy comparable to some antibiotics in studies.
