What is AHA BHA? What Does AHA BHA Do?

JUNE 26, 2025

AHA and BHA are two different skin care ingredients that are very popular in the cosmetics world, whose names we have heard frequently lately. AHA and BHA are two different acids, they work together but with different methods. Come, let's take a closer look at AHA and BHA acids.
What is AHA?
AHA stands for Alpha Hydroxy Acids. AHAs are chemical compounds that are usually derived from natural sources such as fruit and milk. The most common AHAs include glycolic acid (from sugar cane), lactic acid (from milk) and mandelic acid (from almonds). Our skin actually spontaneously removes dead cells, but with age and especially prolonged exposure to the sun, it causes problems such as dullness, dryness, clogged and enlarged pores, swelling, wrinkles, loss of firmness and an uneven skin tone.
AHA has the ability to renew, smooth and tone even out the skin by peeling off dead skin cells in the upper layer of the skin. They can even out skin tone, reduce fine lines and increase skin moisture. In skin care, they are usually found in products such as peeling, tonic and serum.
What is BHA?
BHA stands for Beta Hydroxy Acids. The most common BHA is salicylic acid, usually derived from tree bark. BHA is soluble in oil, which makes it effective in removing excess oily skin and excess oil inside the pores.
BHA is especially used for cleaning acne-prone skin and blackheads. It is effective in shrinking and tightening pores by penetrating deep into the pores. In addition, BHA has anti-inflammatory properties, which can help calm the skin and reduce redness.
Differences Between AHA And BHA:
· AHAs are water-based and usually work on the skin surface, BHA penetrates into the pores as it is oil-soluble.
· AHAs have an overall effect that corrects skin tone, often by renewing and moisturizing the skin, while BHA has a more specific effect, especially on oily skin and in the treatment of acne.
· While AHAs can generally be sensitive to the sun, BHA is less likely in this regard.
Can AHA And BHA Be Used Together?
Yes, you can use the AHA and BHA components together. Especially if you have multiple skin problems such as sunspots, wrinkles, pores, flaking, and dullness, using AHA and BHA together can provide improved results for your skin.
Do AHA And BHA Harm The Skin?
When the AHA and BHA ingredients are well formulated and used correctly, they do not harm the skin. In fact, AHAs strengthen the skin by supporting collagen, while BHAs calm and soothe the skin.
