AllantoinvsPropolis

Allantoin (5-ureidohydantoin) stimulates cell proliferation and tissue regeneration by promoting fibroblast activity, keratinocyte proliferation, and extracellular matrix synthesis including collagen and glycosaminoglycans. It acts as a mild keratolytic by promoting the natural desquamation process—loosening corneocyte adhesion and facilitating shedding—without the irritation, pH disruption, or barrier compromise associated with alpha- or beta-hydroxy acids. Allantoin has anti-inflammatory properties through modulation of prostaglandin synthesis (inhibiting COX-2 and reducing PGE2) and may downregulate pro-inflammatory cytokines. Its moisturizing effect comes from increasing the water-binding capacity of the extracellular matrix and stratum corneum; it is highly soluble and forms hydrogen bonds with water. Allantoin also promotes wound epithelialization. Its safety profile—non-irritating, non-sensitizing, non-comedogenic—makes it suitable for compromised skin, post-procedure care, and infant formulations.

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).
