My daughter's zits

Dot's zits started as 2 micro pustules on her chin 4 months ago and seeing them multiply is just making me nervy...They're now jutted pimple-like bugs that are so hard to prick!We consulted a dermatologist who insanely gave her a million dollar cream,but after a few months with no sign of progress,we dropped the salve. We prohibit sharing of towels and soaps at home,and dot's barely in close contact with playmates so the zits are getting to my head.Really. We're now tying a local balm and I'm praying everyday for an improvement. My daughter is vainglorious that's why I'm desperately seeking for a quick cure.
