I am also an adolescent girl with mixed oily skin. Don't use skin care products that are not suitable for you, especially adults! Don't use mild cleansing products, such as Ponzi and Fumeiling. Buy a cream that suits you. I use Yumeijing children's cream or Baique Ling's moisturizing cream in winter. Of course, Dabao is also very good. I use cucumber cream in summer, which is refreshing and not greasy. Pay attention to daily sun protection. You will be grateful to yourself after many years. Even if you are young, it is very important to pay attention to sun protection.
