Ingredient 101: Lactic Acid...the gentle exfoliant
ingredient 101: lactic acid
Lactic acid is a popular ingredient in many skincare products, and for good reason. It's an alpha-hydroxy acid that is known for its exfoliating and moisturizing properties. Here are 4 facts about lactic acid that you might not know:
1. It's a natural exfoliant
It's a natural exfoliant: Lactic acid is produced naturally in the body during exercise, but it's also found in dairy products like yogurt and milk. In skincare, lactic acid works as an exfoliant by breaking down the bonds between dead skin cells, allowing them to be sloughed away more easily. This helps to reveal brighter, smoother skin and can also help to reduce the appearance of fine lines and wrinkles.
2. IT'S GENTLER THAN OTHER AHA'S
It's gentler than other AHAs: While lactic acid is still an alpha-hydroxy acid, it's considered to be gentler than other AHAs like glycolic acid. This makes it a great choice for those with sensitive skin who may find other exfoliants too harsh.
3. IT'S A HUMECTANT
It's a humectant: Lactic acid also has moisturizing properties. It's a humectant, which means that it can attract and hold onto water molecules. This helps to keep the skin hydrated and can also improve the skin's natural moisture barrier.
4. IT CAN HELP WITH HYPERPIGMENTATION
It can help with hyperpigmentation: Lactic acid can also be beneficial for those with hyperpigmentation or uneven skin tone. It works by breaking down the excess melanin in the skin that can lead to dark spots and patches.
Overall, lactic acid is a versatile and effective ingredient in skincare products. Its gentle exfoliating and moisturizing properties make it a great choice for a wide range of skin types and concerns. If you're interested in incorporating lactic acid into your skincare routine, look for products that contain a concentration of around 5-10% for best results.
