Peptides
Peptides are small chains of amino acids that are important ingredients in modern skincare products. They work like tiny messengers that tell skin cells to perform specific functions, such as producing more collagen or helping skin repair itself. When someone mentions peptides in their resume, they're usually referring to their experience with formulating or working with advanced skincare ingredients. This is similar to other active ingredients like retinol or hyaluronic acid. You might see this term in job descriptions for cosmetic chemists, product formulators, or skincare specialists who develop or work with high-end beauty products.
