Cosrx bha blackhead kinda sting

You could be allergic to salicylic acid. It’s possible because a dermatologist told my sister she was when she broke out using certain products 😅

Your skin should not burn or sting when using a product. This is usually a sign of irritation. If your skin tingles a bit when using acids then thats normal but it really shouldn't sting. Maybe try using a gentler bha or switching to an aha instead since it's much gentler on your skin. I recommend these products. Hope this helps! ❤️

It sounds like it could possibly be irritation. Context also matters, though. How did you apply it? What other products are in your routine? Did the bumps subside?

Do u use BHA toner for the first time ?? If yes , it might be a purging . But make a sure that u start using it slowly . As Long as I know , tht product has a high % of BHA . 🤔 Just in case u’re beginner BHA user , it maybe to strong for u in first time.

Hello Mari. I didn't experience that. You may need to check if there are other underlying concerns i.e dehydrated skin or weakened skin barrier. Try to pause for a while and go back to previous routine that worked for you. Re-evaluate routine to see if it conflicts with other products.
