Mechanistic Highlights |
Representative Evidence (textual citation) |
| Skin-brightening / anti-hyperpigmentation |
0.3 – 0.5 % in gels, lotions, serums |
Competitive tyrosinase inhibitor; down-regulates MITF/CREB signalling, reducing melanin synthesis |
Dahl A. et al., 2013 – 12-week double-blind RCT (54 subjects) showed 0.5 % EA + 0.1 % salicylic acid cream lightened dark spots as effectively as 4 % hydroquinone with better tolerability. (pubmed.ncbi.nlm.nih.gov) |
| Photoprotection & anti-photo-ageing |
0.1 – 0.5 % daily sunscreen boosters or after-sun essences |
Scavenges UV-induced ROS, restores glutathione, up-regulates Nrf2/HO-1, suppresses MMP-1/2 → less collagen breakdown, wrinkle depth ↓ |
Bae J.Y. et al., 2010 – UV-B-irradiated hairless-mouse model showed EA prevented wrinkle formation and epidermal thickening. Chaiprasongsuk N. et al., 2024 – human dermal fibroblast study confirmed Nrf2-mediated antioxidant defence. (pmc.ncbi.nlm.nih.gov, pmc.ncbi.nlm.nih.gov) |
| Anti-inflammatory / barrier support |
0.2 – 1 % in creams, masks |
Inhibits IL-1β, IL-6, TNF-α and ICAM-1 expression in keratinocytes; stabilises epidermal barrier proteins |
Alfei S. & Zuccari G., 2025 – review summarises EA’s down-regulation of pro-inflammatory cytokines in UV-B-exposed skin cells. (mdpi.com) |
| Wound-healing acceleration |
0.25 – 1 % in hydrogels, film dressings |
Enhances antioxidant status, collagen deposition, TGF-β signalling; decreases MMP-9 → faster contraction & re-epithelialisation |
Gürsoy E.N. et al., 2024 – diabetic‐rat full-thickness wounds treated topically with EA + carnosic acid healed markedly faster and showed lower oxidative markers. Primarizky H. et al., 2024 – 2.5 % EA ointment improved histological scores in rat incision model. (researchgate.net, researchgate.net) |
