Not medical advice
Peptide Skin Science publishes general educational information about cosmetic skincare ingredients. It is not medical advice and must not be used to diagnose, treat, cure, or prevent any condition. Always consult a qualified healthcare professional (such as a doctor, dermatologist, or pharmacist) about your individual situation, especially if you are pregnant or breastfeeding, have a skin condition, or take medication.
Cosmetic peptides are not medicines
Throughout this site we distinguish cosmetic peptides (topical skincare ingredients regulated to make appearance claims) from medical and injectable peptides (regulated as medicines, or sold as unapproved “research” chemicals). Nothing here should be read as guidance to buy, prepare, ingest, or inject any peptide product intended for research or non-cosmetic use. Doing so can be dangerous and, in many places, unlawful.
No guarantees
Cosmetic outcomes vary between individuals. Descriptions of what an ingredient may support are general and do not guarantee any specific result for you.
Product references
Where we describe ingredient types or how to evaluate a product, we are offering educational criteria, not a personalised recommendation. If we ever introduce products or affiliate links, any commercial relationship will be disclosed clearly.
External links
We link to third-party sources for verification. We are not responsible for the content, accuracy, or policies of external sites.
Use at your own discretion
By using this site you agree that you are responsible for your own skincare decisions and that Peptide Skin Science is not liable for outcomes arising from reliance on general educational content. Patch test new products and stop use if irritation occurs.
