Thank you for your interest of our product. It doesn't matter with using it for 13 years old howevere that the expiry date of UV mild sunblock is coming soon. If you want to purchase for sun cream, we'd like to recommend that UV SUN PROTECTOR CREAM. It is light texture and very moisturizing. The item code is 483355495. As well, the expiry date is May 19, 2020.
I hope that answers your question.
Thank you again.
