HYDROXYTYROSOL.

Valuable CAS 10597-60-1 / BLEACHING, SKIN CONDITIONING

Hydroxytyrosol, a polyphenol found in olives, is a potent antioxidant surpassing vitamins C and E in efficacy. It offers comprehensive protection against environmental aggressors while actively reducing inflammation and supporting skin's structural integrity. This ingredient is ideal for addressing premature aging, sensitivity, and barrier compromise.

Science

Mechanism of Action

Hydroxytyrosol operates through multiple pathways to improve skin health. As a powerful antioxidant, it neutralizes free radicals generated by environmental stressors like UV radiation and pollution, thereby mitigating oxidative damage linked to premature aging. Its strong anti-inflammatory action reduces key inflammatory markers, including IL-1β, IL-6, IL-8, and TNF-α, effectively calming redness and irritation. It also supports collagen health by promoting its synthesis and inhibiting matrix metalloproteinase (MMP-1 and MMP-3) activity, which protects existing collagen from degradation, leading to improved skin elasticity and firmness. Furthermore, Hydroxytyrosol strengthens the skin barrier, enhances hydration by improving moisture retention, and promotes cell regeneration and proliferation for healthier skin turnover. It exhibits antibacterial properties to help manage skin issues and supports healing processes. Additionally, it provides protective benefits against both blue light and UV-induced damage.

Key findings

  1. 01 An HT-based formulation demonstrated robust transdermal absorption (56% within 24 hours) and exhibited statistically significant anti-inflammatory effects through the reduction of IL-1α and IL-8 release. This formulation also stimulated cell proliferation (evidenced by increased Ki67 expression) and enhanced the epidermal barrier function in reconstructed human epidermis models.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Generally considered safe for topical cosmetic application with minimal reported side effects. However, rare cases of mild skin irritation or allergic reactions may occur in individuals with hypersensitivity to olive-derived products. While a raw material Safety Data Sheet indicates it 'Causes skin irritation' and 'Causes serious eye irritation,' it is 'Shall not be classified as a respiratory or skin sensitiser.' The European Food Safety Authority (EFSA) deemed hydroxytyrosol safe for ingestion at proposed levels for the general population, excluding children under 36 months, pregnant, and breastfeeding women.
