What this trial studies

This clinical trial aims to assess the efficacy of a food supplement compared to a placebo in enhancing skin physiological parameters over a 2-month period. Participants will take either the supplement or placebo daily and will visit the study center at the start, after 28 days, and after 56 days for evaluations. They will also maintain a diary to track their skin status and tolerability. The study is designed as a double-blind, randomized pilot study conducted at a single center.

Who should consider this trial

Good fit: Ideal candidates are non-smoking individuals with normal to dry skin, aged between 18 and 33 BMI, and without any significant skin conditions.

Not a fit: Patients with existing skin pathologies or those currently using medications that may interact with the study product may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a nutritional approach to improve skin and hair conditions for patients.

How similar studies have performed: While similar studies have explored nutritional supplementation for skin health, this specific approach is relatively novel and untested.
