Fact-Checking Standards

We hold ourselves to strict verification standards:

  • Medical and mechanism claims are grounded in peer-reviewed research where available
  • Where clinical evidence is limited or emerging, this is stated explicitly in the article
  • Manufacturer and clinic claims are treated as marketing input, not evidence
  • Dated content is reviewed periodically against new literature

Content Updates & Corrections

Update Policy: Core reference content is reviewed at least annually and whenever material new research is published.

Correction Policy: Substantive errors are corrected promptly; factual corrections are noted on the article with an update date.

Transparency Note

Every article displays its publication date, last update date, and author attribution. We believe in complete transparency about who creates our content and when it was last verified.

Editorial Independence

PDRN Guide is editorially independent. No skincare brand, clinic, or manufacturer pays us to write, review, or recommend their product, and no third party has editorial approval or veto over our content.

Affiliate disclosure: PDRN Guide is a participant in the Amazon Associates program. Some articles — particularly product reviews and comparative guides — contain affiliate links. When you purchase through those links, we may earn a commission at no additional cost to you. Which products we cover, how we rate them, and the recommendations we make are determined by ingredient evidence, formulation quality, and clinical applicability — not by commission rate. Affiliate links are attributed with rel="sponsored".

We do not accept payment for editorial reviews, sponsored placements in core educational content, or undisclosed paid partnerships. If that ever changes, disclosures will appear both site-wide and on the specific article.
