Skincare 101: What’s AHA and BHA?

Do you want smooth, flawless skin? Well, here’s a treat for you! Exfoliation is one of the many steps in a skincare routine. We need to get rid of dead skin cells, unclog pores and promote proper blood flow and collagen production. To do this, one type of exfoliation that’s gaining traction is acids — specifically AHA and BHA.

What are AHA and BHA you ask? And who should use it? And what are the products that contain AHA and BHA?

Alpha-hydroxy acid (AHA), AHA acids, is derived from natural substances such as sugar cane, milk, almonds or grapes. They dissolve the glue that holds skin cells together and traces the skin’s natural repulsion process. In simpler terms, AHA acids are obtained from sugary fruits. This type of acid is mainly used for mild hyperpigmentation such as age spots, melasma, scars, and enlarged pores. AHA is good for dry skin as it is a water-soluble acid. It helps improve the moisture content of the skin.

Meanwhile, Beta Hydroxy Acid (BHA) is best used for acne-prone skin. BHA acids can prevent oil blockages that build up to become blackheads and whiteheads. Since it is oil-soluble, it penetrates further into the skin, resolving deeper skin problems. It dissolves sebum and dead skin that leads to acne. BHA also stabilises the lining of the pores and has antibacterial properties. It is best for users with oily skin and sensitive skin. The use of BHA may help to reduce rosacea-related redness.

According to a review in 2009, AHAs and BHAs yield fuller skin when used together. This may be due to increased collagen production, which can make both the dermis and epidermis visibly plumper. Both share the same exfoliating benefits but vary on different skincare goals. If you’re looking for something for dry skin, it’s best to use AHA. And if you are experiencing an acne outbreak, use BHA.

If you can’t decide and you’re experiencing hyperpigmentation, acne or dry skin, it is better to use both AHA and BHA. It is the two-stroke acid treatment of fine lines, sun damage, dark spots, as well as acne. Buy products that contain both ingredients or alternate between your AHA product and BHA product every night or every week. Since both are exfoliants and if used excessively may cause dryness and irritation.

Here are some products that contain AHA and BHA:
