Topical therapy
Topical agents used for treatment of acne include creams,lotions and gels. The choice of preparation depends on the extent of area affected: creams and gels are preferred for small areas,and lotions are reserved for larger surfaces such as the upper torso. They should be applied to the entire site that is prone to acne rather than to the acne lesions alone. Most topical preparations can cause skin irritation,resulting in erythema,desquamation,dryness,stinging and pruritus,especially if applied excessively. Skin irritation can be improved by initiating the treatment at a low dose on alternate days,slowly titrating upward as required. A simple topical regime is recommended to improve compliance.
Benzoyl peroxide (BPO; 2.5% or 5%) has comedolytic,anti-inflammatory and bactericidal actions against Cutibacterium acnes (C. acnes). It can be used alone or in combination with topical antibiotics or retinoids. The use of BPO in itself does not induce bacterial resistance,and it can be used in pregnancy. In addition to skin irritation,BPO can cause bleaching of hair or clothing.
Topical retinoids (tretinoin,adapalene) are Vitamin A derivatives that reduce microcomedones and mature comedones,promote desquamation of follicular epithelium and have an anti-inflammatory effect. Tretinoin may cause photosensitivity,and the use of sunscreens is advised. Clinical evidence does not support the belief that topical retinoids cause a flare-up in acne in the initial few weeks.) Adapalene is better tolerated than tretinoin,as it causes less skin irritation.) Topical retinoids are recommended for maintenance after successful treatment of acne.
Acne creams and lotions are available over the counter and contain active ingredients such as sulfur,salicylic acid and resorcinol. These topicals induce a comedolytic effect by causing inter-corneocyte cell detachment; they improve skin texture and are recommended for inflamed comedones.","department":"
