BHA (beta hydroxy acid) is what you know as Salicylic Acid and is mostly derived from willow bark. Other than AHA, salicylic acid is lipophilic, which means it is oil-soluble and able to penetrate into your pores and unclog them. The anti-bacterial and anti-inflammatory properties of BHA are another reason why they are preferred by acne-prone skin types.
Choose BHA as your weapon if you are troubled by:
Your BHA product should as well have the pH level between 3 and 4. The only thing that could go wrong when your are using products higher than 4 is that they might still be anti-bacterial but they wont work as exfoliators. Regarding the percentage of BHA there is a simple guideline:
Just like AHA, starting with 2-3 times a week will already give you significant results. Make sure to apply your BHA product directly after cleansing and toning your skin and wait until fully absorbed before continuing with your further skin care routine. And of course: always use sun screen in conjunction with BHA. We recommend using BHA in the evening, however, you can also wear it during the day, but be sure to double the sun screen application then.
In terms of BHA, we are especially crazy over COSRX BHA Blackhead Power Liquid. This essence isn’t made of salicylic acid, but betaine salicylate, which is BHA’s kind little sister. What does that mean for your skin? Basically it means that the exfoliation is even more gently and mild in order to prevent over-exfoliation, yet very effective. Willow bark water instead of plain water is another upgrade, as willow bark water has BHA properties as well. The essence itself is super lightweight and absorbs very quickly.
