COMBINATION SKIN

A majority of people have combination skin; their skin is oily and dry. The oily skin part on their face forms a T or known as the T-zone. The T-zone resides on the forehead, nose, and chin areas and the rest being dry skin areas. Combination skin are also prone to acne, but can be easily controlled. Every night while taking a shower you should wash your face with a mild cleanser(choose one that's for combination skin or with salacylic acid in it). After you finish taking a shower and dry up, apply lotion (oil-less) to areas of dry skin. In the morning, just splash your face off with warm water, dry your face, and apply lotion to areas of dry skin again. This time, you might want to apply an oil-less lotion with SPF because you are likely to go outside. Remember to only apply lotion minimally since only some parts of your face are dry, so squeeze your lotion bottle a little bit.

You should still exfoliate like every 3 weeks. But if you have mild or severe acne, I would say forget it about it. The acids in the exfoliator will probably excerbate your skin condition. This goes the same for facial masks. You can exfoliate and use facial masks if you only have light acne.
If you are going to use facial masks, I would say to just apply it on the T-zone area, your dry-skin areas are mostly clean and free of dirt if you already wash your face daily.

Drink at least a couple bottles of water everyday. Avoid smoking, alcohol, tea, and coffee as much as possible. Eat plenty of fruits and vegetables. Again, no junk food, fast food, sugary, and salty food of any kind. We all know this, but a few do it. It's true what they say: you are what you eat.
