AHAs - A must have in your sincare routine

8 September 2021

Smooth, fine, ceramic skin with no pores or unevenness. If you want to achieve the ceramic skin you've always dreamed of, I recommend using skincare products that contain AHAs. Overseas dermatologists have introduced the skin beautifying effects of AHAs and the precautions to take when using them.

What is AHA?

According to Dr. Kenneth Howe, a dermatologist at Wexler Dermatology in New York State, AHAs (Alpha Hydroxy Acids) are a type of acid that is used to remove dead skin cells, which can cause dull and rough skin.

AHAs are often referred to as "fruit acids" because they are extracted from sugar cane or other plants (such as apples or citrus)," Dr. Howe said on Byrdie. In particular, glycolic acid, which is derived from sugar cane, has the smallest molecule among AHAs and is less irritating, so it is widely used in skin care products.

What are the skin beautifying effects of AHAs?

In addition to removing sebum and dead skin cells that cause acne and dullness, Dr. Howe says that AHAs can be expected to have a variety of skin beautifying effects, such as promoting collagen production and improving wrinkles.

The first effect is a "peeling effect" that improves the skin's texture.

Dr. Howe said, "AHAs are said to be beneficial for both the epidermis and dermis of the skin. In the epidermis, the peeling effect of AHAs removes dead skin cells from the surface of the skin. In the epidermis, the peeling effect of AHAs removes dead skin cells from the surface of the skin by gently breaking down the adhesions that remain between the dead skin cells and the skin. Once the bond is separated, the dead skin cells will naturally fall off the surface of the skin," he said.

The second skin beautifying effect is the anti-aging effect, which improves fine lines and wrinkles and blemishes on the skin.

Dr. Howe explained, "AHAs are expected to stimulate collagen production by fibroblasts (one of the cells that produce the ingredients that make skin beautiful), and at the same time, reduce the breakdown of the ingredients that support skin elasticity. These effects will lead to plump and firm skin.

Points to note when using AHAs  

As you can see, AHAs are expected to have various skin beautifying effects, such as removing dullness and stiffness, and improving the skin's elasticity and luster.

However, one thing to keep in mind is the strength of the acid. According to Dr. Ole Henriksen, a cosmetic dermatologist in Denmark, it is not advisable to increase the concentration of AHAs in order to see results quickly, as it may exfoliate the skin too much, causing it to become sensitive, red, and brittle.

Dr. Henriksen said, "(Using AHAs) is like an exercise. It's important to keep a balance with the whole body. Especially since the skin is a living, breathing organ that you have to live with for the rest of your life, it's important to find a balance," he told Beauty Crew Australia, advising against overuse of AHAs.

AHA is a skin care ingredient that leads to smooth and beautiful skin. However, some people may find it irritating, so it is best to start with a mild product and use it only once or twice a week.
