Peptides are a popular anti-aging ingredient that functions as a structural building block for the skin. Essentially, they are short chains of amino acids that act as messengers, signaling the skin to perform specific tasks. Because they are not artificial concoctions or very potent acids, they are generally well-tolerated by most skin types. In my experience, they have a low risk of causing irritation when integrated into a standard routine.

When we discuss the potential for a reaction, it is crucial to distinguish between the ingredient itself and the product formulation. Peptides themselves rarely irritate the skin. In fact, many high-quality peptide complexes are designed to soothe, possessing soothing properties that assist in calming signs of irritation.
