Acids are substances that have a pH below 7.0. They taste sour and turn litmus paper from blue to red. Acids are found in many different places in nature, including fruits, vegetables, and even our own bodies.
In the skin, acids play an important role in maintaining the acid mantle. The acid mantle is a thin layer of skin that helps to protect the skin from harmful bacteria and fungi. It also helps to keep the skin hydrated.
There are two main types of acids that are used in skincare: alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs). AHAs are water-soluble acids that come from fruits, such as glycolic acid and lactic acid. BHAs are oil-soluble acids that come from plants, such as salicylic acid.
AHAs and BHAs work by exfoliating the skin. This means that they remove dead skin cells from the surface of the skin. This can reveal brighter, smoother, and more radiant skin.
AHAs and BHAs can also help to reduce the appearance of fine lines and wrinkles. They can also help to improve the texture of the skin.
However, it is important to note that acids can be irritating to the skin. It is important to start with a low concentration of acid and to gradually increase the concentration over time. It is also important to use acids in conjunction with a moisturizer to help protect the skin from dryness.
If you experience any irritation, stop using the acid and consult with a dermatologist.
Here are some tips for beauty professionals and estheticians on how to practically treat and take care of their clients with acids:
- Start with a low concentration of acid and gradually increase the concentration over time.
- Use acids in conjunction with a moisturizer to help protect the skin from dryness.
