Mechanism of Action
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.
Propolis
CAPE (caffeic acid phenethyl ester) inhibits NF-kappa B nuclear translocation by preventing I-kappa B alpha degradation and blocking p65/p50 nuclear import — suppresses TNF-alpha, IL-1beta, IL-6, COX-2 transcription. Flavonoids (chrysin, pinocembrin, galangin) provide antioxidant protection through free radical scavenging and metal chelation. Bacteriostatic and bactericidal against Cutibacterium acnes and Staphylococcus aureus via cell wall disruption and protein synthesis inhibition. Promotes wound healing: stimulates fibroblast collagen I/III synthesis, keratinocyte migration (integrins, matrix metalloproteinases), angiogenesis. Inhibits hyaluronidase, preserving skin hyaluronic acid. Effective for acne (reduces inflammation, bacterial load) and sensitive skin (calming barrier disruption).

Full Profiles
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.
Propolis →
A resinous substance produced by honeybees from tree buds, used to seal and protect the hive. Propolis contains over 300 bioactive compounds including flavonoids, phenolic acids, and caffeic acid phenethyl ester (CAPE). In skincare, it provides potent anti-inflammatory, antimicrobial, and wound-healing effects. Popular in Korean skincare for acne-prone and sensitive skin.
