You may have some skin issues that can be tough to deal with. If your skin is sensitive and oily, try using mild products without perfumes. Possibly, dark spots, skin rashes and pigmentation could occur due to irritation caused by harsh components in the product you are using. Go for products labeled as non-comedogenic so that they do not block the pores on your face.
