The Effect of 16-week Dietary Intake of Food Supplements Containing Collagen and MSM on Facial Erythema and Other Skin Parameters

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 women aged 40 to 65 years 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 objectives are to evaluate the effect on facial erythema after 8 weeks and the effects on telangiectasiae severity and other redness-related skin parameters. Other skin parameters will be assessed as supportive endpoints, and differences between the two investigational formulations will also be explored.
