The Claim

Daily supplementation with 5.0 grams of porcine collagen peptides for three months significantly reduces facial erythema and improves skin tone uniformity in healthy adults, potentially through anti-inflammatory mechanisms or modulation of cutaneous blood flow.

Cause and effect

In plain English

Taking 5 grams of collagen pills every day for three months might help reduce redness in your face and make your skin tone look more even. This could happen because the collagen calms inflammation or changes how blood flows to your skin.

See the scientific wording

Three months of daily 5.0-gram porcine collagen peptide supplementation significantly reduces facial redness in healthy adults, as measured by standardized dermatological imaging. This reduction in erythema suggests that oral collagen intake may exert anti-inflammatory effects or modulate cutaneous blood flow, offering a non-topical approach to managing facial redness and improving overall skin tone uniformity over a quarter-year period.

What the research says

  1. Study: Effect of Reducing Pigmentation by Collagen Peptide Intake: A Randomized, Double-Blind, Placebo-Controlled Study

    Taking 5 grams of collagen peptides every day for three months was found to significantly reduce facial redness in healthy adults, supporting the idea that oral collagen can help improve skin tone.
