Exfoliating with AHA and BHA, is there any difference?

Jan 24,2022 | HISEEK PRETTY

A leave-in AHA (alpha hydroxy acid) or BHA (beta hydroxy acid) exfoliator can make a difference in the appearance of your skin. We're often asked which one is better, and the answer isn't as complicated as you might think.

But first, we answer the question, "Why go horny?

Our skin naturally sheds dead cells every day, but over time (mainly due to aging and unprotected skin from the sun) this shedding process slows down and may stop altogether. Causes undesirable skin problems including dull, dry, or peeling skin; clogged, enlarged pores; acne, wrinkles, firmness, and uneven skin tone.

Helps the skin gently remove dead skin buildup (like our skin's natural renewal behavior when we are young), revealing beautiful, soft, and hydrated skin hidden beneath dead cells.

How AHA and BHA exfoliants work

AHAs work on the surface layer of the skin to remove aged keratin and dead skin cells that accumulate on the skin. It can also lighten acne scars by removing damaged skin cells. One thing to note is that you must use it before using any oil-based skincare products. This is because products with oily ingredients will block AHA from penetrating the skin for maximum effect.

On the contrary, BHA is highly soluble in fat, and salicylic acid is the most common BHA acid in skincare products, which is more suitable for oily skin. It works with the skin's natural oils to penetrate deep into the skin's tissue. Its characteristic is that it penetrates deeper into the pores (which is different from AHA), and can purify the whiteheads, blackheads, and excess oil that have been accumulated in the pores for a long time.
It is also slightly milder than AHA in nature (but it can still dry out the skin), so it can be used on red, inflamed skin. In addition, it works better when combined with oily products and is often used to treat acne-prone skin.

AHAs have the same advantages as BHAs:
– Reduce visible fine lines and wrinkles
– Makes skin look firmer
– hydration
– Improves the appearance of dull, uneven skin tone
– Smoothes rough skin texture
But both have their own unique properties that make them the first choice for certain skin types and concerns.

How are AHAs and BHAs different

AHAs act on the surface of the skin and are water-soluble. They are typically used on normal to dry, sunburned skin because of their ability to enhance the natural moisturizing factors within the skin. They have been shown to be effective in reducing visible sunburn marks. BHA works on the surface of the skin and inside the pores; it is oil-soluble, so it is best for normal to oily skin that is prone to clogged pores, blemishes, and enlarged pores.

Some Precautions for Using AHA and BHA Products

Many products use both AHAs and BHAs, and while high doses can cause skin irritation, it's advisable to look for a moisturizing lotion or exfoliating pad that already has a combination of AHAs and BHAs for a balanced formula. Best of all, if your skin needs more TLC (think enlarged pores, deep wrinkles, or bumps), you can use a 2-in-1. Gentle formula lessens the burden on your skin
