How to deal with post makeup acne?

If this is repetitive then you should visit a good dermatologist. If you are from Delhi then I suggest you some good clinics here. Also start cutting dairy products from your diet.

Try to cool down your skin after removing your makeup. Like put cold aloe gel or a sheet mask.

You should change the makeup product, Definitely! it will help you!

I think you should check your products and the ingredient list. Also always use clean brushes to apply makeup. Sometimes using dirty makeup blushes can lead to acne. And also prep your skin well before applying makeup.
