Combination skin is a mixture of both dry and oily skin. It can range from having mostly dry to mostly oily skin. Typically, people that have combination skin will likely experience an oily t-zone, and other parts of their face will be quite dry.
Having combination skin is quite a common occurrence, and it is typically caused because of sebum production. While some parts of your skin may not produce much sebum, other parts will contain a lot of it.
While having combination skin is common, it can be difficult when shopping for skincare products as you don’t want to purchase anything that is too drying, but you will also want to avoid overly oily products.
