Normal Skin
You got lucky! Your skin care routine is very simple. All you need to do is wash your face with a mild cleanser twice a day and moisturize.
Dry Skin
Wash with mild cleanser daily to prevent creating even drier skin. Moisturize afterward with an unscented and alcohol-free moisturizer. On occasion, exfoliate the dead dry skin off. The key to your routine will be moisturizing because obviously your skin lacks it.
Oily Skin
You should wash your face several times a day because your skin tends to be acne prone with open pores. When you get a pimple, do not touch it because your fingers oils will transfer to your face and if you pick at it, it can inflame and become irritated.
Combination
Your T-zone is oily and the rest of your skin is dry. You should wash twice a day with soap and water to remove extra dirt and oil and moisturize only your dry spots.
