How to treat Blackheads effectively?

You could try a cleansing oil or jojoba oil. Massage the area in circular motion until the blackhead is out.

Salicylic acid exfoliator and mask and niacinamide serum are the three things that help me to not have blackheads anymore 🤗

Make sure you also double cleanse and avoid comedogenic ingredients. Also, keep it mind, that stubborn blackheads may only be extracted manually - which you should see a professional about. To keep them away, also use niacinamide, clay masks, hydrate and moisturise lots 💦

Maybe you could also try incorporating benzoyl peroxide into your routine.

maybe a low % retinol might help, I tried it it seems less than before
