I've recently noticed that my forehead is getting really tan, and I realized I've never really paid much attention to my skincare until now. I'm 24 and have started using a Himalaya walnut scrub, neem face wash, and kesar face pack for about a month. I can see some improvement on my cheeks but not on my forehead. Also, since I started using the neem face wash, I get a lot of pimples. They seem to clear up after using the face wash, but new ones just pop up in different places. What can I do to get rid of the tan on my forehead and prevent these pimples?
