Peptides are one of the top skincare trends for 2023 – and for good reason. If you want an active that smoothens, plumps, and helps make your skin firmer without any irritation, they are exactly what you’re looking for. Made of amino acid chains which are essentially the building blocks of protein in our skin, peptides help your skin go into repair mode and signal for more collagen and elastin production. The result is younger-looking skin. Pair it with retinol to double up on the benefits. Bonus: Peptides also help battle irritation, making them ideal for sensitive skin.
