Summary

The aim of this study is to compare the effects of 16 weeks of daily dietary supplementation with two investigational products containing collagen, methylsulfonylmethane (MSM), and vitamin C on skin parameters in comparison to a placebo product. The study will be conducted in healthy human subjects with visible facial erythema and telangiectasiae (cheeks), stable for ≥3 months, without active rosacea. The primary objective is to demonstrate beneficial effects of the investigational products on facial erythema. The secondary objective is to evaluate the effect of the investigational products on facial telangiectasiae severity. Other skin parameters will be assessed as supportive endpoints, and differences in efficacy between the two investigational formulations will also be evaluated.

Detailed description

This is a single-centre, randomized, double-blind, placebo-controlled, one-period effectiveness study designed to evaluate the effects of multiple-dose, daily dietary supplementation over a 16-week period on skin parameters in healthy human subjects. The study population consists of subjects with visible facial erythema and telangiectasiae predominantly on the cheeks, stable for at least 3 months prior to inclusion, and without clinical signs of active rosacea. Eligible participants will be randomized to receive one of two investigational products or a placebo product, administered as a daily oral dose of 30 mL for 16 consecutive weeks. The investigational products contain the following compositions: Investigational Product 1 (IP1): collagen 10 g, methylsulfonylmethane (MSM) 2.0 g, and vitamin C 160 mg; and Investigational Product 2 (IP2): collagen 5 g, MSM 1.5 g, and vitamin C 160 mg. The primary objective of the study is to evaluate whether 16 weeks of supplementation with the investigational products results in a beneficial effect on facial erythema compared with placebo. The secondary objective is to assess the effect of the investigational products on facial telangiectasiae severity. Supportive objectives include the evaluation of additional skin parameters and the assessment of differences in efficacy between the two investigational formulations.
