What are alpha and beta hydroxy acids?

There’s a clear difference between alpha and beta hydroxy acids. Alpha hydroxy acids are from fruits rich in sugar, and they are water-soluble. They draw a tremendous amount of hydration to the skin, combatting dryness. There’s some evidence that they can increase the production of collagen and elastin, making the skin firmer and more elastic. Therefore this could have anti-aging benefits like eliminating wrinkles on the forehead and fine lines, dark circles under eyes, and bags under eyes. (1)

Some common alpha-hydroxy acids include lactic and glycolic acids. Lactic acid is the milder of the two, and it’s often used to even out skin tone and get rid of areas of pigmentation. In addition, it’s antimicrobial, and it deeply hydrates the skin. (2)

Glycolic acid is probably the best alpha hydroxy acid, because of its amazing ability to delve deep down and restore hydration. It also has anti-aging properties, as it leads to the production of collagen. This makes the skin firmer, consequently smoothing out wrinkles and frown lines. (3)

Beta hydroxy acids are oil-soluble, which allows them to penetrate deep into the skin. They can eliminate dead skin cells, oil, and unclog the pores. These acids are helpful for the treatment of acne scars. They are most suitable for people who have oily skin. In addition, they have potent anti-inflammatory properties which can effectively treat skin conditions. (4)

The most common beta hydroxy acid is salicylic acid, which is for the treatment of acne. It penetrates the pores to exfoliate, removing oil and other substances, and killing bacteria. Additionally, it can get rid of areas of pigmentation on the skin. This acid is a peeling agent. (5)

What do alpha and beta hydroxy acids do?

The benefits of alpha and beta hydroxy acids for the skin are tremendous. They can exfoliate deeply, eliminate acne, moisturize the skin, provide anti-aging benefits like eliminating wrinkles under the eyes, lighten the skin, and lessen age spots and areas of pigmentation. These are some of the most potent skincare ingredients available. Therefore if you have skin problems, do some research on these substances and talk to your dermatologist about whether they are right for you.

What’s the difference between alpha and beta hydroxy acids?

The main difference between alpha & beta hydroxy acids is in what they do. Alpha hydroxy acids are water-soluble and derived mostly from fruits, except for lactic acid which comes from dairy products. When it comes to the skin, this substance tends to remain more on the surface providing moisture and producing collagen.

Beta hydroxy acids are oil soluble and derived from a number of sources. Salicylic acid, for example, comes from the bark of a willow tree. This substance tends to work beneath the surface of the skin, delving deep to eliminate oils and dirt in the pores.
