The Claim
Daily oral supplementation with 5.0 grams of collagen peptides fermented with Aspergillus sojae significantly reduces visible facial pigmentation in healthy adults, with statistically significant improvements in pigmented macules observed within one month and larger patches within two months, demonstrating comparable or superior efficacy to standard collagen peptides.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 5 grams of a special fermented collagen supplement every day can help fade dark spots on your face. You might start seeing results in just a month, and it works just as well or even better than regular collagen supplements.
See the scientific wording
Daily consumption of 5.0 grams of collagen peptides fermented with Aspergillus sojae effectively decreases visible facial pigmentation in healthy adults, with statistically significant reductions in pigmented macules appearing after one month and larger pigmented patches reducing after two months. This fermented formulation provides a comparable or potentially accelerated benefit for visible skin spots compared to standard collagen peptides, indicating that fermentation processes may enhance or maintain the efficacy of collagen-derived supplements on skin pigmentation.
What the research says
1 studyThe study directly compared fermented collagen peptide (FCP) intake to a placebo over 3 months. The time-course analysis showed significant reductions in macules at 1 month and patches at 2 months, providing evidence that the fermented formulation actively reduces visible pigmentation over time.
