Bad reaction help

Serge

***update

Just one day after using the Mustela face cleanser my bud skin got clear!

This thing is magic !

My son face took turn for the worse and got red it’s been a week instead of what I thought was acne get better it actually got worse!

I had only washed it and put aquaphor on it but I won’t even do that anymore !

Should I call my pediatrician!

It looks like a reaction to something bad

What should I do !!?
