The Ultimate Guide to Lactic Acid: Benefits, Side Effects, and Uses

Welcome to our blog post about lactic acid! If you’re into skincare, there’s a good chance you’ve heard of this ingredient before. Lactic acid is a type of alpha-hydroxy acid (AHA) that is commonly used in skincare products. It is derived from milk and is known for its ability to exfoliate the skin and promote cell turnover. In this article, we’ll take a closer look at what lactic acid is and how it can benefit your skin.

Benefits of Lactic Acid

Lactic acid is a popular ingredient in skincare products for a reason. It can provide a variety of benefits for your skin, including:

  • Exfoliation: Lactic acid is a gentle exfoliant that can remove dead skin cells from the surface of your skin. This can help to improve the texture and tone of your skin.
  • Moisturization: Unlike some other exfoliants, lactic acid has moisturizing properties that can help to keep your skin hydrated.
  • Brightening: Lactic acid can help to fade dark spots and hyperpigmentation, leaving your skin looking brighter and more even-toned.
  • Anti-aging: Lactic acid can help to stimulate collagen production, which can reduce the appearance of fine lines and wrinkles.

How to Use Lactic Acid

If you’re interested in incorporating lactic acid into your skincare routine, there are a few things you should keep in mind. First, it’s important to start slowly. Lactic acid can be harsh on the skin if used too frequently or in concentrations that are too high. You should begin by using it once or twice a week and gradually increase the frequency as your skin adjusts.

It’s also important to choose the right product. Look for a product that has a concentration of around 5-10% lactic acid, and be sure to patch test it before applying it to your entire face. If you have sensitive skin, you may want to opt for a product that contains a lower concentration or use it less frequently.

Products with Lactic Acid

There are a ton of products on the market that contain lactic acid. Here are a few that we recommend:

  • The Ordinary Lactic Acid 10% + HA: This serum contains a high concentration of lactic acid and also includes hyaluronic acid to hydrate the skin.
  • Paula’s Choice Skin Perfecting 8% AHA Lotion: This lotion contains a blend of AHAs and BHAs, including lactic acid, to exfoliate and smooth the skin.
  • Biossance Squalane + Lactic Acid Resurfacing Night Serum: This serum contains a gentle concentration of lactic acid and also includes nourishing squalane to moisturize the skin.


If you’re looking for a gentle yet effective way to exfoliate your skin and improve its overall appearance, lactic acid may be the right ingredient for you. Just remember to start slowly, patch test any new products, and choose a concentration that works for your skin type. With consistent use, you may notice brighter, smoother, and more hydrated skin.
