Science
Mechanism of Action
HYDROLYZED PUNICA GRANATUM FRUIT EXTRACT functions through multiple pathways to enhance skin health. Abundant in polyphenols, ellagic acid, punicalagins, and vitamin C, it acts as a powerful antioxidant, neutralizing free radicals induced by UV radiation and pollution, thereby mitigating cellular damage and reducing visible signs of aging. Its anti-inflammatory action suppresses nitric oxide production and inhibits pro-inflammatory cytokines, calming irritated skin and potentially aiding in conditions such as eczema and acne. Ellagic acid specifically targets melanin synthesis by chelating copper ions in tyrosinase, leading to a reduction in hyperpigmentation and improved skin tone uniformity. Furthermore, it supports enhanced skin hydration, stimulates collagen production for improved elasticity and firmness, and helps to regulate sebum levels.

Key findings
- 01 Significantly reduced crow's feet wrinkles, tactile roughness, forehead fine lines, and forehead wrinkles, while improving skin radiance, tone evenness, moisturization, elasticity, and firmness over 60 days. Also reduced tyrosinase biomarker levels by 3%.
- 02 Observed significant decreases in melanin content over a 60-day study in 25 healthy volunteers, with no dermal irritation.
- 03 Sensitization tests in humans were negative.
- 04 Notably decreased hydrogen peroxide-induced Reactive Oxygen Species (ROS) production and exhibited promising antioxidant effects by decreasing hydrogen peroxide-induced apoptosis and downregulating caspase-3 and caspase-7 levels in HaCaT cell cultures.

Stability
Aqueous extracts of pomegranate demonstrate high storage stability at low pH, ideally around 3.5, and when preserved in dark packaging. Elevated pH levels can negatively impact the spectral and antioxidant characteristics of the extract.
Safety
Safety Profile
The CIR Expert Panel has deemed Punica Granatum Fruit Extract (a related ingredient) safe for cosmetic use under specified conditions. The FDA generally recognizes related pomegranate extractives as safe (GRAS) for food use. Human studies with Punica Granatum Fruit Extract and concentrated pomegranate juice have shown no dermal irritation or sensitization, indicating a very low irritation potential at standard concentrations. The 0.1% max concentration guideline applies to Punica Granatum Fruit Extract in face/neck/night skin preparations.
