Granulysin peptides ended up also uncovered to be powerful versus P. zits and could form an alternative therapy against zits in long term (McInturff et al. 2005).
If pimples are significant and not amenable to benzoyl peroxide therapy, a single must consult a skin doctor for prescription medications like topical retinoids (Tretinoin, Adapalene and Tazarotene), topical antibiotics (clindamycin, erythromycin), oral isotretinoin, oral antibiotics (doxycycline, minocycline).
