Antiacne agent (topical)
Acne vulgaris(treatment)—Topical clindamycin is indicated in the treatment of acne vulgaris. It may be effective in grades II and III acne, which are characterized by inflammatory lesions such as papules and pustules. Topical antibacterials are not generally considered to be as effective as systemic antibacterials in the treatment of acne, especially more severe inflammatory acne. However, some studies have shown that clindamycin phosphate topical solution may be as effective as low-dose tetracycline for moderate cases of inflammatory acne.
Skin infections, bacterial, minor (treatment)—Topical clindamycin is used in the topical treatment of erythrasma caused by Corynebacterium minutissimum , rosacea, periorificial facial dermatitis, folliculitis, stasis, chronic lymphedema, and familial pemphigus.
Ulcer, dermal (treatment)—Clindamycin phosphate topical solution is used in the treatment of dermal ulcers.Not all species or strains of a particular organism may be susceptible to clindamycin.
Topical clindamycin is not effective in the treatment of deep cystic lesions or noninflammatory lesions.
This acne solution only works for the mild and occasional breakouts, but if you have read my previous article about Ultima II Immediate Rescue Stick, I think they both works the same, but this is half the price.
