Detailed answer

Cryotherapy, which involves freezing the skin, is not a suitable treatment for blackheads. Blackheads are formed by clogged hair follicles with excess sebum and dead skin cells. Cryotherapy does not address the root cause of blackheads, and the extreme cold temperature may potentially damage the skin, leading to further issues. It is recommended to use topical treatments containing salicylic acid or benzoyl peroxide to effectively treat blackheads. Regular exfoliation and maintaining a proper skincare routine can also help prevent their formation.
