Who should use peptides in their skincare routine?

Peptides benefit anyone concerned with early signs of aging, loss of firmness, or skin barrier integrity. They are particularly valuable for those in their 30s and beyond who want to support collagen levels. Because they are generally non-irritating, peptides are also a great option for sensitive skin that cannot tolerate retinol or acids. They work best in a leave-on serum or moisturizer, not a rinse-off product.
