Recently, AHA and BHA are the most searched "keywords" when it comes to chemical dead cell removal methods. So what makes these two ingredients hot in today's exfoliating products?

BHA And AHA: Which Is The Best Choice For Your Skin?

As we all know, the skin has an automatic mechanism to excrete billions of cells every day. However, due to many reasons such as time and environment impacts, this mechanism is weakened and slowed down. If you don't want clogged pores, dry dull skin and acne, removing dead cells is a must for protecting your skin.

Currently, the removal of dead cells is commonly known in two ways: physical removal of dead cells and chemical exfoliation. Normally, removing physical dead cells will use products containing large, rough seeds to rub against the skin's surface, removing dead cells from the surface. However, due to mechanical impact, your skin can be at risk of scratches and irritation during the process. Chemical exfoliation helps to gently but thoroughly clean skin and is often used for sensitive or acne-prone skin.

Among the countless ingredients of chemical dead cells, including AHA and BHA stands for Alpha Hydroxy Acid (such as glycolic acid or lactic) along with Beta Hydroxy Acid (Salicylic Acid) - The perfect solution in the present dead cell removal. Based on proven research, AHA and BHA are both a group of acids originating from nature, so they have great effects and are safe for the user. Not only helps remove dead cells, these two ingredients are also capable of minimizing acne, helping to remove blemishes, significantly improving wrinkles and smoothing the skin.

In addition, AHA and BHA both work according to the general principle that when impacted on the skin, the top surface structure of the horny layer is broken, helping to remove damaged dead cells, promoting new cell production. However, the 2 ingredients have many differences, which will cause many misunderstandings if you do not understand correctly about the product.
