Optimization of dose of collagen hydrolysate to prevent UVB-irradiated skin damage

Collagen hydrolysate (CH) was orally administered to UVB-irradiated hairless mice at doses of 20, 200-2000 mg/kg BW/day. The low dose of CH increased the skin hydration and reduced the transepidermal water loss on damaged skin. These results suggested the optimal dose of collagen to improve the UV-damaged skin condition.
