I have several dark spots on my nose. Overtime they are increasing in number and now I also have a few on my cheeks or just below my eyes. Most of them look like brown spots while some look like tiny moles on the skin. I have a combination sensitive skin and I'm not prone to acne. I use a sunscreen when I go out and also cover my face. I would like to know the reason these spots are appearing and how to lighten them or get rid of them completely. I am almost 28 years old unlike the what the app calculated.
