Lactic acid is a type of alpha-hydroxy acid (AHA) that is found in many skincare products. It is a natural compound that is produced by our bodies during exercise and is also found in milk and other dairy products. In skincare, lactic acid is used to exfoliate the skin, promote cell turnover, improve skin texture, tone & hydration. But what exactly is lactic acid, and how does it benefit the skin? Let's take a closer look.
What is lactic acid?
Lactic acid is a type of AHA that is derived from milk. It is a water-soluble compound that is composed of an alpha-hydroxy group (COOH) and a carboxyl group (OH). Lactic acid is a mild acid that has a pH of around 3.5, which makes it gentle enough to use on the skin.
How does lactic acid benefit the skin?
Lactic acid is a popular ingredient in skincare products because it offers a range of benefits for the skin. Here are some of the ways that lactic acid can benefit your skin:
- Exfoliation:
Lactic acid works by breaking down the bonds between dead skin cells, which allows them to be gently sloughed off. This process helps to unclog pores and smooth the skin's texture, which can improve the appearance of fine lines, wrinkles, and acne scars.
- Moisturisation:
Lactic acid is a humectant, which means that it helps to attract and retain moisture in the skin. This can help to keep the skin hydrated and prevent dryness and flakiness.
- Brightening:
Lactic acid can help to brighten the skin by promoting cell turnover. When old skin cells are shed, new, fresh cells are revealed, which can help to give the skin a more youthful, radiant appearance.
- Acne-fighting:
Lactic acid can be effective at treating acne because it helps to unclog pores and exfoliate the skin. It also has antibacterial properties, which can help to kill the bacteria that cause acne.
How to use lactic acid in your skincare routine
If you're interested in incorporating lactic acid into your skincare routine, there are several ways to do so. Lactic acid is a common ingredient in many types of skincare products, including cleansers, toners, masks, and serums. When using products that contain lactic acid, it's important to start slowly and gradually increase your use over time, as overuse can cause irritation and dryness.
In conclusion, lactic acid is a natural compound that offers many benefits for the skin. From exfoliating and brightening to moisturising and acne-fighting, lactic acid can help to improve the overall health and appearance of your skin. If you're looking for a gentle yet effective way to improve your skin, consider adding lactic acid to your skincare routine.
