BENEFITS OF HYDROLYSED COLLAGEN SUPPLEMENTATION IN SKIN’S PHYSIOLOGY OF MIDDLEAGED PORTUGUESE WOMEN
N. Tavares Ann Nutr Metab 2013;63(suppl 1):1552
Background and objectives:Collagen play a key role in normal dermatologic functioning. However, very few is known about the effects of hydrolysed collagen supplementation on skin’s functions.We evaluated the effects resulting fromhydrolysed collagen intake in skin’s water profile and biomechanicsin mature women.
Methods:Using data from measurements of transepidermal water loss, epidermal capacitanceand biomechanical behaviour, before and after 30 days of supplementation we evaluated effects on skin’s physiology in 18 women, 52.3y (SD±7.3). Volunteer’s hydration status was assessed by plasma osmolality.
Supplementation consisted in 2,5 g hydrolysed collagen or placebo each day for 30 days. A randomized, placebo-controlled, double-blind trial was chosen.
Results: The marker of hydration status was within the range of normalcy for all women. Hydrolysed collagen supplementation significantly increased skin hydration (p=0.000) and elasticity (p=0.000). Significant variation in transepidermal water loss could not be observed.
Conclusions: In the present experimental conditions, a 2,5 g per day oral hydrolysed collagen supplementation improved skin hydration and elasticity.
