The Claim
Daily oral supplementation of 5.0 grams of porcine collagen peptides significantly reduces the number and surface area of visible facial pigmented patches and macules in healthy adults over a one to two month period, demonstrating a measurable improvement in skin appearance through the modulation of skin pigmentation processes.
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 pig collagen pills every day for one or two months can visibly reduce dark spots and patches on the face. This happens because the collagen helps regulate how your skin produces pigment, leading to a clearer complexion.
See the scientific wording
Daily oral supplementation of 5.0 grams of porcine collagen peptides significantly reduces the number and surface area of visible facial pigmented patches and macules in healthy adults within one to two months of consistent intake. This intervention demonstrates a measurable improvement in skin appearance by targeting hyperpigmented areas, suggesting that specific collagen-derived peptides can modulate skin pigmentation processes when consumed regularly over a short-term period.
What the research says
1 studyTaking 5 grams of collagen peptides daily for one to two months was shown to significantly reduce dark spots and patches on the skin. This supports the idea that regular collagen supplements can help improve skin pigmentation.
