A Guide to Acids in Skincare: AHA vs. BHA

This one is for all my skincare girlies! Let’s talk a little bit about acids—one of the powerhouse ingredients in many skincare products. If you’ve ever wondered what the difference is between the types of acids you see on ingredient lists, I’ve got you covered. Today, we’re breaking down the two main types: Alpha Hydroxy Acid (AHA) and Beta Hydroxy Acid (BHA).

These two acids are commonly found in everything from cleansers and toners to serums and moisturizers. But how do you know which one is right for your skin? Well, the answer is—it depends! It all comes down to your skin type and the concerns you’re trying to address.

AHA vs. BHA: What’s the Difference?

• Alpha Hydroxy Acids (AHAs): AHAs, such as glycolic acid, are water-soluble and primarily work on the skin’s surface. Think of them as tiny brooms sweeping away dead skin cells, revealing a brighter, smoother complexion. AHAs are best for normal to dry skin types and are great for tackling dullness, uneven skin tone, and fine lines.
• Beta Hydroxy Acids (BHAs): The most well-known BHA is salicylic acid. Unlike AHAs, BHAs are oil-soluble, meaning they can penetrate deeper into the pores to dissolve excess oil and debris. If you have oily or acne-prone skin, BHAs can help unclog pores, reduce breakouts, and regulate oil production.

Which Acid Should You Choose?

• Normal to dry skin? Go for an AHA like glycolic acid to exfoliate and brighten your complexion.
• Oily or acne-prone skin? Opt for a BHA like salicylic acid to help control excess oil and prevent breakouts.

While there are other acids that fall somewhere between these two categories, AHA and BHA are the most commonly used and widely recognized in skincare.

Why Are Active Ingredients Important?

Active ingredients like AHAs and BHAs play a crucial role in your skincare routine because they are formulated to target specific concerns. Unlike basic hydrating or cleansing products, actives work on a deeper level to improve the skin’s texture, clarity, and overall health. By incorporating the right acids into your routine, you can see real, noticeable changes in your skin over time.

So next time you’re shopping for skincare, take a closer look at the ingredients list! Knowing the difference between AHAs and BHAs will help you make informed choices and get the most out of your skincare routine. Happy glowing!
