The easiest way to know your skin type is to perform an oil-blooting sheet test. Place the sheets on your forehead, nose, cheeks, and chin area. If the sheets pick up oil all over the face, you have oily skin. If they only catch oil on the T-Zone (forehead, nose and chin) you have combination skin. If the sheets appear dry and your skin feels tight and flaky on most days, you have a dry or dehydrated skin.
Determine what your skin concerns are. Is it uneven skin tone, excess oil, blemishes, early signs of ageing, dehydration, dullness or large pores?
Decide which concern you want to give priority to then find a skincare range for your skin type taht addressnes that problem. Its best to stick with products within the range to experience optimum benefits.
