NCT06755892

Brief Summary

The aim of the study is to compare the effects of multiple-dose 16 weeks daily dietary supplementation with 5 g or 3 g of collagen in combination with 1 g or 1.5 g of MSM and 80 mg vitamin C (see 1.2. Investigational and placebo product profile) 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.

Outcome Measures

Primary Outcomes (1)

  • Change of dermis density from baseline in all test groups in comparison to placebo group after 16 weeks of dietary supplementation

    Significant change of dermis density from baseline in test groups, in comparison to placebo group after 16 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.

    16 weeks

Secondary Outcomes (5)

  • Change of wrinkle volume from baseline in test groups, in comparison to placebo group after 16 weeks of dietary supplementation

    16 weeks

  • Change of skin texture from baseline in test groups, in comparison to placebo group after 16 weeks of dietary supplementation

    16 weeks

  • Change of skin redness from baseline in test groups, in comparison to placebo group after 16 weeks of dietary supplementation

    16 weeks

  • Change of dermis thickness from baseline in test groups, in comparison to placebo group after 16 weeks of dietary supplementation

    12 weeks

  • Change of skin elasticity from baseline in test groups, in comparison to placebo group after 16 weeks of dietary supplementation

    16 weeks
