Treatment

It will be much easier to treat now we have been able to link the various symptoms to a skin type.

Type A: the right approach for this type is cleansing.
This is the most direct method to get rid op dirt and grease. In addition, try avoid touch your cheeks too often, otherwise you will make them more greasier.
 
Type B: the different zones should be approached differently.
T-zone - double cleanse methode and hydration; it is important to deep cleanse/exfoliate your T-zone periodically. 
U-zone - regular cleansing methode and hydration; moderate cleansing, otherwise it will dehydrate your skin.

Oil control is important on the T-zone, while U-zone needs hydration. One is not more important than the other, so don't skip one of the two zones during your routine!

Type C: often is a greasy face caused by a dehydrated skin. A layer of sebum, dust and dirt is left on the face and forms a mixture which causes microbial infection, this leads to a sensitive skin and/or other skin troubles.
Your skin is overproducing oil and sebum because it is so dehydrated and it is trying to protect itself (it gets the wrong signals). A dehydrated skin is going to produce more oil and sebum to keep itself hydrated.

Start with the cause by intensively add moisture to your skin. Try an essence or serum, since these are high concentrated and is it easy to be absorbed by the skin. (Sheet masks contains essences).

Cleansing Pre-cleanse It is very important to remove your makeup each night. The best moment to do is this immediately upon returning home, dirt and grease won't get a chance to further withdraw into your pores. Oil-based If you have a oily skin, try to use oil based makeup removers. "Wash away oil with oil" and it also exfoliates. Double Cleanse Use a mild cleanser and cleanse your face with care and right method. Be gentle to your skin and clean it by massaging with your fingertops in circular movements. Don't rub or scrub abusively and cleanse with moderation! Extra cleanse After cleaning, dry your face and then gently sweep your face with a toner on cotton pad. In this way you can remove the remaining dirt residues and cleansers, while the cotton pad can help to remove the softened dead skin cells.
