Around 3 months back my right cheek developed a patch of really tiny bumps and they just won't go away. My skin looks textured there because of it. There is no redness and it doesn't feel itchy. What is it and how can I get rid or it? My skin care routine is pretty simple.. at night I use vitamin C, niacinamide, glycolic acid 6 % cream. Each Is applied on alternate days and layered with Cetaphil mositurizer. I used to apply glycolic acid on alternate days but later I reduced it to twice a week because before that I didn't know that it's bad to regularly exfoliate. But this came on my skin out of nowhere. I had smooth skin and now this is annoying me! When I apply foundation it looks too obvious
