How to Use Lactic Acid in Your Skincare Routine

If you’re interested in incorporating lactic acid into your skincare routine, there are a few things to keep in mind:

  1. Start with a low concentration: If you’re new to using lactic acid, it’s a good idea to start with a product that has a low concentration (around 5-10%) and gradually work your way up.
  2. Use it at night: Lactic acid can make your skin more sensitive to the sun, so it’s best to use it at night and be sure to wear sunscreen during the day.
  3. Don’t overdo it: Overusing lactic acid can lead to irritation and dryness, so it’s important to follow the instructions on the product and not use it more often than recommended.
