Beauty By Peptides is an independent blog about peptides in skincare and wellness. We break down what peptides are, what they may do, and which products and trends are worth your attention, in plain language.
What we cover
- Skincare peptides: copper peptides (GHK-Cu), Matrixyl, Argireline, PDRN and the serums, creams and eye creams that use them.
- Collagen: collagen peptide supplements, powders and what they can and can’t do for skin, hair and joints.
- Wellness and weight-loss peptides: explainers on peptides people are searching for, such as BPC-157, sermorelin and GLP-1 medications, including their risks and regulatory status.
- Reviews, comparisons and news: product launches, ingredient comparisons and new research as it comes out.
How we research our posts
We start with the questions people are actually asking about peptides. For each topic, we look at published studies, product ingredient lists, brand information and guidance from regulators such as the U.S. Food and Drug Administration (FDA). When a post refers to a study or official source, we link to it so you can read it for yourself. We update posts when new information changes the picture.
Our goal is to explain what the evidence shows, including where it is limited. Many peptides, especially injectable ones, have little human research behind them, and we say so.
Not medical advice
Everything on Beauty By Peptides is for general educational purposes only. It is not medical advice and is not a substitute for advice from a doctor or other licensed healthcare provider. Some of the peptides we write about are not approved by the FDA for human use. Always talk to a qualified professional before starting any new treatment, supplement or injectable, and never ignore professional advice because of something you read here.
