skin falls under one of these categories- normal, oily, dry, combination and sensitive skin. Your skin texture and type can change as it is affected by a lot of outside factors as well such as the weather, your lifestyle, hormonal changes and your diet. The ideal way to understand your skin type is to wash it gently and leave it overnight without using any product to observe your skin the next morning. Use a face blotting paper or tissue and wipe the t-zone , c-zone and o-zone separately. If parts leave an oily smear and the rest don’t you have combination skin.. if your sheet is oily all over you obviously have oily skin, if not it’s dry and if you are prone to redness and itching when you go out in the sun or after using certain products you have sensitive skin. Normal skin is what children have and you are lucky if you fall under this category.
