BHAs, or Beta Hydroxy Acids, are a type of acid most known for their ability to exfoliate inside the pores. The most common BHA is salicylic acid, and it's a superstar ingredient for treating acne, blackheads, and oily skin.

What are BHA acids?

BHAs or Beta Hydroxy Acids - are a little different from their AHA cousins. You know how AHAs work on the surface of your skin to get rid of dead cells? Well, BHAs are oil-soluble. That's a fancy way of saying they can actually get inside your pores. This unique ability makes them a total go-to for anyone dealing with oily skin, blackheads, or breakouts.

So, what's the deal with them?

They clear out your pores. BHAs, like salicylic acid, go into your pores and break up all the oil, dead skin, and other stuff that causes blackheads and pimples.
They calm things down. They also have anti-inflammatory properties, so they help calm down redness and irritation that comes with breakouts.
Who should use them? BHAs are perfect for people with oily or acne-prone skin. If you struggle with blackheads, whiteheads, or just a generally shiny complexion, a BHA product can be a game-changer.

A few quick tips:

Start slow. Don't jump right in with a super strong product. A couple of times a week is a great start, especially if your skin is a bit sensitive.
Use it at night. It's best to apply BHA products in the evening as part of your skincare routine.
Sunscreen is a must. Since BHAs are an exfoliant, they can make your skin more sensitive to the sun. So, you absolutely need to use SPF 30 or higher every single morning, no matter what.

BHA products can make a real difference for your skin. When you use them correctly, you can get a much clearer, smoother complexion.
