SkinCited is an evidence-based platform that evaluates supplements and natural compounds for skin health. We analyze peer-reviewed clinical research to help consumers understand which ingredients have scientific support for various dermatological concerns, from acne and aging to sun protection and skin barrier function.

How does SkinCited evaluate skin health supplements?

We review randomized controlled trials, systematic reviews, and meta-analyses published in dermatology and nutrition journals. Each ingredient is assessed for its level of clinical evidence, studied dosages, and safety profile, with particular attention to both oral and topical routes of administration.

Are the supplements on SkinCited FDA-approved for skin conditions?

Dietary supplements are not FDA-approved to treat, cure, or prevent any disease, including skin conditions. The FDA regulates supplements under different rules than prescription drugs or over-the-counter topical treatments. SkinCited presents published research findings, not medical recommendations.

Can I use SkinCited to replace my dermatologist's advice?

No. SkinCited is an educational resource and should not replace professional dermatological care. Skin conditions can indicate underlying health issues and may require prescription treatments. Always consult a dermatologist for persistent or severe skin concerns before relying on supplements.

Is SkinCited free to use?

Yes, SkinCited provides free access to evidence-based information about skin health supplements. Our goal is to help consumers navigate the complex landscape of beauty-from-within supplements with reliable, research-backed information.

Evidence Grading System

Every supplement claim on this site is graded on an A–D scale based on peer-reviewed clinical research from PubMed. Our algorithm evaluates study design (RCTs rank highest), consistency of results, sample sizes, and the overall body of evidence. No manufacturer sponsorship influences our grades.

A Strong Evidence

Multiple randomized controlled trials (RCTs) or meta-analyses with consistent positive results and large sample sizes.

B Good Evidence

At least one RCT with mostly consistent results across studies. Evidence suggests benefit but more research may be needed.

C Some Evidence

Small studies or observational data with some positive signals. Promising but insufficient for strong recommendations.

D Very Early Research

In vitro studies, case reports, or pilot studies only. Early-stage research that requires clinical validation.
