Arm 3: enhancement of skin firmness
The DermaLab SkinLab USB elasticity module was used to assess the effect of Pure Gold Collagen on skin firmness in 67 healthy volunteers. Measurements were carried out on the ventral left forearm after 50, 80, and 130 days of treatment with Pure Gold Collagen. Mean values were recorded and considered significant when P was ≤0.05 (by analysis of variance). In 37% of subjects taking Pure Gold Collagen, an increase in skin firmness was observed at 80 and 130 days. This improvement was statistically significant at 80 days (83%; P≤0.05) and at 130 days (94%; P≤0.01; Figure 6).
