Combination Skin – varies according to your skin type. This is the Jekyll and Hyde type of skin, often with split personality. This type may be characterized as oily on the T-zone (the area that stretches from the forehead down to the nose and chin), and dry to normal on the cheeks and around the eye area.
Sensitive Skin – people with sensitive skin are the most prone to allergies, rash, sting, and burns. This type of skin gets irritated easily and can go very red and blotchy. This type will have a lot more trouble to environmental factors and tends to be very sensitive to cosmetics.
Know your skin and take care of it. Whatever your skin type is, you can always find an acne treatment product that will work for you.
