Background: This study aimed to evaluate the efficacy and safety of oral hydrolyzed collagen peptide (HCP) in healthy females by assessing the skin parameters via biophysical and skin imaging techniques. Methods: 112 females were randomly assigned to receive either HCP (n = 57; 10 g CollaSel Pro®) or placebo (n = 55; 10 g maltodextrin) daily for eight weeks. The contribution of HCP to skin elasticity, hydration, and roughness was investigated against a placebo, while the facial soft tissue sagging (RMS) and safety data were also recorded. Results: HCP was associated with significant improvements in skin elasticity (p = 0.009), skin hydration (p ranged from 0.003 to <0.001), and skin roughness (p ranged from 0.002 to <0.001). In the HCP vs. the placebo group, week eight values for skin elasticity (43.0 (7.4) vs. 40.3 (3.3) mPa, p = 0.017), skin hydration (65.8 (18.9) vs. 53.1 (14.9) g/m3, p < 0.001) and skin roughness (40.2 (20.4) vs. 24.9 (20.9) g/m3, p < 0.001) were significantly higher. In the HCP group, week 8 RMS values were significantly lower than baseline values (1.02 (0.21) vs. 1.10 (0.21) mm, p = 0.012). Conclusions: CollaSel Pro® HCP can be considered a well-tolerated, safe product that effectively improves dermal health and the appearance of sagging and ameliorates the signs of the aging process.
