Efficacy of an Oral Skincare Supplement on Skin Aging: A 12-Week Randomized, Double-Blind, Placebo-Controlled Trial

Aging leads to structural and compositional changes in the skin, contributing to more wrinkles, less smoothness, and dryness. There is growing interest in oral non-invasive interventions to help ameliorate visual signs of skin aging. The purpose of this study was to evaluate the efficacy of an oral skincare supplement containing hyaluronic acid and wheat oil extract on parameters of skin aging in a diverse population. Healthy adults (ages 26–64) were recruited and randomly assigned to the intervention group (n = 31) or placebo group (n = 32). The intervention group received an oral skincare supplement consisting of wheat oil extract and low molecular weight sodium hyaluronate, with a 12-week follow-up period. The intervention group demonstrated a significant reduction in crow's feet wrinkles and improvements in both facial and global skin smoothness beginning at week 8 and continuing to week 12, compared to the placebo group. Additionally, the intervention group exhibited significant increases in skin hydration and elasticity in the leg region relative to the placebo group. Dermatologists' evaluations revealed significant reductions in global scores of both deep and fine wrinkles from baseline to week 12, but only in the intervention group. By week 12, a greater proportion of participants in the intervention group reported improvements in fine lines and wrinkles, skin radiance/glow, skin resilience/elasticity, and overall signs of aging, with these changes being significantly different from the placebo group. An oral skincare supplement combining wheat oil extract and hyaluronic acid offers a comprehensive method for addressing skin aging, providing measurable clinical improvements in various skin parameters and enhancing subjective perceptions of skin health and appearance. ClinicalTrials.gov identifier, NCT06083402. As we age, our skin undergoes changes that result in wrinkles, dryness, and reduced smoothness. This study examined whether taking a daily oral supplement containing hyaluronic acid and wheat oil extract could improve signs of skin aging. We conducted a 12-week study with 63 adults aged 26–64 years who were randomly assigned to take either the skincare supplement or a placebo. Using specialized equipment and dermatologist evaluations, we found that participants taking the supplement showed significant improvements in crow's feet wrinkles and skin smoothness starting at week 8. They also experienced better skin hydration and elasticity in the leg area compared to those taking the placebo. Dermatologists observed reductions in both deep and fine wrinkles in the supplement group. By the end of the study, more participants taking the supplement reported improvements in fine lines and wrinkles, skin radiance, elasticity, and overall signs of aging compared to the placebo group. These findings suggest that this oral supplement may provide a non-invasive approach to improving multiple aspects of skin aging in a racially diverse study population.
