Peptides: all products

Peptides represent one of the most studied categories in modern cosmetics and supplementation. They are short chains of amino acids that perform specific biological roles and, thanks to research over the last few decades, have become key ingredients in formulations for skin care, hair care, and more. In this collection, you will find 176 selected products with peptides as the declared active ingredient, to help you navigate with clarity.

How to choose the right peptide product for you

The first criterion for selection is the form and intended use: peptides can be found in serums, creams, ampoules, shampoos, and in the context of supplementation, in powders and capsules. Each format addresses different needs. For facial routines, water-based serums promote greater penetration of active ingredients compared to more occlusive creams; for systemic use, it is essential to read the label carefully and, in case of any doubts, consult your doctor or pharmacist. The second criterion is the type of peptide: there are signaling peptides, carrier peptides, neuromodulators, and structural peptides on the market, each with a different action profile indicated in the technical data sheet. Always check the declared concentration and the position of the ingredient in the INCI or ingredient list.

A common mistake is layering too many active products in the same routine without considering compatibility: for example, peptides may be less stable in the presence of exfoliating acids at very low pH. It is also common to purchase based solely on the name of the peptide without considering the overall formulation, which largely determines the effectiveness of the finished product. Take the time to read the product sheet and, if necessary, seek advice.

Frequently Asked Questions

Are peptides suitable for all skin types?

In general, peptides are considered well-tolerated and compatible with most skin types, including sensitive skin. However, as with any active ingredient, it is advisable to perform a patch test on a small area before full use.

Can I use a peptide-based supplement without consulting a doctor?

For dietary supplements, it is always advisable to read the warnings on the label carefully and consult your doctor or pharmacist, especially in cases of specific conditions, pregnancy, or medication use.
