You seem to be concerned about the acne vulgaris which is usually a self limiting disorder primarily of teenagers and young adults but in 10 to 20% cases ,it may persist into late adulthood.
The typical lesions are comedones or pimples which are small cysts formed in hair follicles due to blockage of follicular orifice by retention of sebum and keratinous materials. The activity of bacteria Proprionobacterium acnes within the comedones releases free fatty acids from sebum, causing inflammation and red or erythematous papular lesions. Some patients may have hard nodular lesions which may result in scarring on scratching and trauma.
Mild disease may respond to topical therapy with retinoic acid, benzoyl peroxide or salicylic acid. Topical antibacterial agents such as azelaic acid, erythromycin or clindamycin are useful in decreasing inflammation. Severe acne with prominent inflammatory component may require systemic therapy with tetracycline or erythromycin. Hormonal therapy(with oral contraceptives containing ethinyl estradiol and norgestimate) is also useful in females who do not respond to oral antibiotics. If nodulocystic acne do not respond to above therapies, isotretinoin may be useful though side effects like teratogenicity, depression, dry skin, cheilitis and hypertriglyceridemia should be kept in mind and toxicity monitored.
You can discuss all the treatment options with your dermatologist who will suggest the best treatment for you as same cannot be done online
I sincerely hope that it helps. Take care.
