Just use "tea tree essential oil" for B's acne. Although tea tree essential oil is a little expensive, it is better than spending those wasted money. I spent countless money in the past, alas, fortunately, I won't do it again.
I only have one bottle of tea tree essential oil and one bottle of lavender essential oil at home, just in case.
Lavender essential oil is specially used to repair skin.
Tea tree oil treatment, lavender restoration, you can't even think about it. The good news is that essential oil is pure natural.
