Elementary school child acne

The elementary school child is worried about acne.

A pimple like a millet-sized acne has appeared on my forehead.

It seemed to improve after changing the lotion and paying more attention to cleansing.

A little bit of blackheads are forming on the side of my nose, like black spots.

I'm so upset that there's a blackhead on that soft baby skin. ㅜ

How should I manage this?

I'm currently using Innisfree Visa Lotion.

I use natural soap that is good for acne for cleansing.

Shall we buy proper cleansing instead of that?

Or should I do something like a volcanic pumice pack?

It's just starting to form, and I'm in fourth grade.

To my eyes, it's still baby skin, but I'm worried that using something harsh might make it worse ㅠ

I'm really not very interested in cosmetics or anything like that.

I'm upset because my mom doesn't know anything ㅜ
