Olive Young's best-selling products are generally mild and easily accessible, making them recommended for skincare beginners or those looking for reliable products. If you have dry and sensitive skin, Atobarrier 365 Cream, Round Lab Dokdo Toner, or Birch Juice Moisturizing Sunscreen are worth considering. Before purchasing products, it's good to consider your skin type and seasonal factors and refer to other reviews. Especially for oily skin, Torriden Serum or Atobarrier Cream might feel a bit heavy.
