Brief Summary
The aim of the randomized, double-blind, placebo-controlled, one-period effectiveness study is to compare the effects of multiple-dose 12 weeks daily dietary supplementation with 10 g collagen alone or 5 g or 10 g of collagen in combination with MSM on skin in healthy human subjects in comparison to placebo product. The main objective is to show that test products have beneficial effects on dermis density, and also on other skin parameters and to investigate differences in the effects among test products.

Conditions
Outcome Measures
Primary Outcomes (1)
Change of dermis density from baseline in all test groups in comparison to placebo group after 12 weeks of dietary supplementation
Significant change of dermis density from baseline in test groups, in comparison to placebo group after 12 weeks of dietary supplementation with study product is expected. Dermis density will be assessed through ultrasonographic dermis intensity measurement. Differences in change of dermis density between test groups under primary objective conditions will also be evaluated.
12 weeks
Secondary Outcomes (6)
Change of wrinkle volume from baseline in test groups, in comparison to placebo group after 12 weeks of dietary supplementation
12 weeks
Change of skin texture from baseline in test groups, in comparison to placebo group after 12 weeks of dietary supplementation
12 weeks
Change of skin hydration from baseline in test groups, in comparison to placebo group after 12 weeks of dietary supplementation
12 weeks
Change of TEWL from baseline in test groups, in comparison to placebo group after 12 weeks of dietary supplementation
