Some people believe that allowing tweens to experiment with makeup can be a form of self-expression and creativity. It can be a way for them to explore their identity and develop their own sense of style. Also, some argue that learning about makeup at a younger age can help them develop good skincare habits early on.
On the other hand, some worry that wearing makeup at a young age can contribute to a focus on appearance and potentially lead to body image issues or pressure to conform to certain beauty standards. There's also the concern that some makeup products might contain ingredients that could be harmful to young skin. And, some parents simply feel that tweens should focus on being kids and not worry about makeup just yet.
