AHA, BHA, PHA ? What's the difference between them ?

- 0 Comments

Hi K-SECRET Lovers! Today topic is AHA, BHA, and PHA

I guess most Korean skincare lovers already know these three ingredients. But, do you guys know the exact differences between AHA, BHA, and PHA?

Even if you don't know, don't worry. I'm going to explain it.

Then, now it's time to start!

 1. AHA 

AHA (Alpha Hydroxy Acids) is acids found in natural stuff like fruits and sugar cane. This is well known as a chemical exfoliator. It pushes away dead skin cells naturally so it makes sense it can resurface and improve skin texture.

2. BHA

According to Wikipedia, BHA (Beta Hydroxy Acids) is an organic compound that contains a carboxylic acid functional group and the hydroxy functional group separated by two carbon atoms.

It has quite different efficacy compared to AHA. It is good for controlling excessive sebum, clogged pore, and acne so, I can say BHA is suitable for oily skin type!

 3. PHA 

PHA (polyhydroxy acids) is the next generation exfoliator. PHA is similar to AHA. But PHA's molecule size is larger than AHA. It can't go through the skin deeper than AHA and BHA. That why it causes less irritation and suitable for sensitive skin. Besides, PHA retains moisture well and strengthens the skin barrier.
