Can I use peptides withvitamin C Navigating the world of skincare ingredients can feel like a complex puzzle, especially when considering how different actives interact. A common question among skincare enthusiasts is: can I use peptides with lactic acid? The answer, while seemingly straightforward, involves understanding the nuances of ingredient compatibility and potential for irritation. While some sources suggest caution, a closer look reveals that with the right approach, these powerful ingredients can coexist and even enhance your skincare routine.

Understanding the Ingredients: Peptides and Lactic Acid

Before diving into their compatibility, it's essential to understand what peptides and lactic acid are and what they do for the skin.

Peptides are short chains of amino acids, the building blocks of proteins like collagen and elastin.What Not to Mix Peptides With in Your Skincare Routine When applied topically, peptides act as signaling molecules, telling your skin cells to perform specific functions.
