If you’re having trouble figuring out what type of skin you have, it’s likely combination. Is your skin dry in certain areas, while oily in theirs? Combination skin is most easily defined by an oily T-zone (the strip across the forehead and the line down the nose) and dry or normal skin on the rest of the face.
You’ll want to stay away from the same ingredients as oily and dry skin, such as alcohol-based products. The name of the game with combination skin is balance. Isolate problem areas with spot treatments and use toners or balancing cream to even out the skin.
