Based on the reviews, the Birch Moisture Tone-Up Sun Cream is generally not recommended for oily skin. Several reviewers with oily skin reported that the product tends to become greasy or shiny over time, and some mentioned that it pills or feels sticky.

However, some users with combination skin found it suitable, especially when paired with a mattifying powder or used in moderation. It's important to note that individual experiences may vary, and it might be beneficial for users with oily skin to apply it in a thin layer or use it in conjunction with other products to manage oiliness.
