What are your favorite BHA products?

I’ve used a few BHA products in the past such as the PURITO Centella Pads and ISNTREE’s Clear Skin BHA Toner. However, they didn’t get rid of my blackheads so I’m currently looking for a more potent BHA product. I have pretty sensitive skin and I can’t tolerate alcohol, essential oils, and comedogenic ingredients. I’m thinking about getting PURITO’s new AHA/BHA Refreshing Solution but I’m afraid that it’ll be too harsh for my skin. It has 7% glycolic acid and 2% salicylic acid so I feel like the concentrations are kind of high. However, I’m currently using the ISNTREE Clear Skin 8% AHA Essence which has 4% lactic acid and 4% glycolic acid, and I haven’t really had any bad reactions besides an initial purging that only lasted a few days. So, if anyone has BHA product recommendations, then please let me know!
