Thanks for writing to us.
Protein powders in no way are used for acne treatment.
You need to consult a dermatologist
to start a proper treatment in form of topical anti acne creams like clindamycin
and tretnoin singly or in combination along with oral medication like azithromycin/ doxycycline or isotretinoin
. The faster the lesions resolve, lesser are the chances of pigmentation and scarring.
Hope that helps.
