Ingredients higher up in an ingredient list are typically present in a larger amount. Glycolic Acid is arguably the most famous alpha hydroxy acid (AHA) with tons of research backing its benefits. It is found naturally in sugar cane but the form used in skincare is usually synthetic for purity and stability. Glycolic acid removes the top layer of dead skin cells to allow newer and fresher ones to emerge. AHAs work by breaking down the structural “glue” that holds old skin cells in place. When that buildup is gone, your skin can renew itself more efficiently. Research also shows glycolic acid stimulates collagen production, helping to firm and thicken the skin over time. This is one of its biggest advantages over other AHAs. Overall, glycolic acid helps with: Fun fact: Glycolic acid boosts skin hydration by helping it produce molecules that increase hyaluronic acid naturally. To work best, glycolic acid products should have a pH between 3-4 (that’s where exfoliation is most effective but still gentle on skin). The pH and concentration of a product are key to its effectiveness: It is normal to feel a slight stinging sensation when using glycolic acid. This usually fades as your skin adjusts. Because glycolic acid has the smallest molecular size in the AHA family, it can penetrate deeper, which enhances its effectiveness but also makes it more likely to irritate sensitive skin. If your skin is very sensitive or prone to rosacea, glycolic acid may be too strong; in that case, try milder options like lactic acid or a PHA instead. Recent studies suggest glycolic acid might even help protect against UV damage. But don’t skip sunscreen! Freshly exfoliated skin is more sensitive to the sun. Glycolic acid is a skincare superstar. It smooths, brightens, hydrates, and firms the skin. Unless you’re highly sensitive, it’s well worth adding to your routine.

Cellulose is a sugar found in plant cell walls and help give plants structure. This ingredient helps stabilize products by preventing ingredients from separating. It can also help thicken the texture of a product. This ingredient can also be found in pill medicines to help our bodies digest other ingredients. Panthenol is a common ingredient that helps hydrate and soothe the skin. It is found naturally in our skin and hair. There are two forms of panthenol: D and L. D-panthenol is also known as dexpanthenol. Most cosmetics use dexpanthenol or a mixture of D and L-panthenol. Panthenol is famous due to its ability to go deeper into the skin's layers. Using this ingredient has numerous pros (and no cons): Like hyaluronic acid, panthenol is a humectant. Humectants are able to bind and hold large amounts of water to keep skin hydrated. This ingredient works well for wound
