Efficacy and safety of a proprietary Punica granatum extract in skin health - a randomized, placebo-controlled clinical study in healthy volunteers

Objectives: The concept of beauty from within is a growing trend in the market and people now look for oral supplements that can enhance the well-being of skin from within. Within this principle, a proprietary pomegranate extract (Grantria^®), standardized to ellagic acid, punicic acid and punicalagin, was developed using ADOP (Advanced Oil-Powder) technology and was clinically evaluated for its efficacy and safety in healthy adults.

Methods: This evaluation was carried out as a randomized, placebo-controlled clinical study for 60 days at a daily dose of 300 mg. This study involved a total of 60 subjects randomized in the ratio of 1:1 to test group and placebo group. Multiple skin health parameters were evaluated before and after the intervention.

Results: Data from this study indicated that Punica granatum extract significantly reduced crow's feet wrinkles, tactile roughness, forehead fine lines, forehead wrinkles and improved skin radiance compared to the placebo in 60 days. Other skin health attributes like pores, spots and UV pigmentation were also observed to exhibit significant changes. The test group showed a significant improvement in skin tone evenness, skin moisturisation, elasticity and firmness compared to the baseline. The Tyrosinase biomarker levels were observed to drop by 3% in the Grantria^® supplemented group.

Conclusions: Grantria^® was found to be effective, safe, and well accepted by the subjects making it a potential candidate for use in the supplements intended for maintaining healthy and glowing skin.
