Recommended skincare products for middle school son (acne)

Since my son entered middle school, he has developed small pimples on his skin.

I went out, and now I have a lot of acne on my forehead and cheeks. It comes and goes, and it's a mess~ My skin is also turning red...

I'm using a skincare product that is rumored to be good for calming acne on Instagram, but I wonder if I can get even better information. I'm posting this.

Please recommend some good cosmetics for acne-prone skin~~
