Combination skin has both oily and dry areas. The T-zone, which is straight down the middle of the face, will have larger pores and secrete more oil, while the outer part of the face will be normal or dry. It can also appear dry or flaky due to by dehydration. The goal with this skin type is to use products that can address both oily and dry areas, using water-based products that cleanse and exfoliate to help keep the skin balanced.
Acne is a disorder of the oil glands, caused by a buildup of dead skin cells, excessive oil production, and bacteria trapped in pores. This leads to inflammation and eventually breakouts. The goal with this skin type is to use products that deeply clean the skin to reduce excess oil buildup, exfoliants that help to unclog pores, and calming and soothing products to ease inflammation.
