Your skin type is determined by genetics. There are four basic types: oily, dry, normal & combination skin. A 'normal' skin type is well-balanced skin (not too oily & not too dry); a 'combination' skin type means your skin is varied. Usually, it is oily on the t-zone (forehead, nose & chin) & dehydration on the cheeks. You may also have some breakouts & enlarged pores.
