Combination, oily to acne-prone skin

With combination, oily and acne-prone skin, the skin’s sebum production is not properly regulated. 
In combination skin, the skin is only oily on the T-zone, which has many sebaceous glands.
In oily skin, the quantity of sebum is excessive over the entire face. 
Oily skin can become acne-prone and blemishes can appear on the face and/or body if sebum quality is altered and if certain bacteria multiply abnormally.
