Early and effective treatment of acne<unk> ring can prevent severe acne and the<unk> ring that often follows. In 2004, no prescription drugs for the treatment or prevention of<unk> s were available. Chemical peels Chemical peels are chemicals which destroy the epidermis in a controlled manner, leading to exfoliation and the alleviation of certain skin conditions, including superficial acne<unk> s. Various chemicals can be used depending upon the depth of the peel, and caution should be used, particularly for dark-skinned individuals and those individuals susceptible to keloid formation or with active infections. Filler injections Filler injections of collagen can be used to raise atrophic<unk> s to the level of surrounding skin. Risks vary based upon the filler used, and can include further disfigurement and allergic reaction. Laser treatment Nonablative lasers, such as the 585 nm pulsed dye laser, 1064 nm and 1320 nm Nd:YAG, or the 1540 nm Er:Glass are used as laser therapy for hypertrophic<unk> s and keloids. There is tentative evidence for burn<unk> s that they improve the appearance. Ablative lasers such as the carbon dioxide laser (CO) or Er:YAG offer the best results for atrophic and acne<unk> s. Like dermabrasion, ablative lasers work by destroying the dermis to a certain depth. Healing times for ablative therapy are much longer and the risk profile is greater compared to nonablative therapy; however, nonablative therapy offers only minor improvements in cosmetic appearance of atrophic and acne<unk> s. Combination laser therapy and microneedling may offer superior results to single modality treatment. The biggest recent advance in<unk>  management is the use of fractionated CO laser and immediate application of topical steroid Triamcinolone. Radiotherapy Low-dose, superficial radiotherapy is sometimes used to prevent recurrence of severe keloid and hypertrophic<unk> ring. It is thought to be effective despite a lack of clinical trials, but only used in extreme cases due to the perceived risk of long-term side effects. Dressings and topical silicone Silicone<unk>  treatments are commonly used in preventing<unk>  formation and improving existing<unk>  appearance. A meta-study by the Cochrane collaboration found weak evidence that silicone gel sheeting helps prevent<unk> ring. However, the studies examining it were of poor quality and susceptible to bias. Pressure dressings are commonly used in managing burn and hypertrophic<unk> s, although supporting evidence is lacking. Care providers commonly report improvements, however, and pressure therapy has been effective in treating ear keloids. The general acceptance of the treatment as effective may prevent it from being further studied in clinical trials. Verapamil-containing silicone gel Verapamil, a type of calcium channel blocker, is considered a candidate drug for the treatment of hypertrophic<unk> s. A study conducted by the catholic university of Korea concluded that verapamil‐releasing silicone gel is effective and is a superior alternative to the conventional silicone gel where decreased median SEI, fibroblast count, and collagen density in all verapamil‐added treatment groups were observed Gross morphologic features suggested that the combination of verapamil and silicone improves the overall quality of hypertrophic<unk> s by reducing<unk>  height and redness. This was verified with quantifiable histomorphometric parameters. but Oral verapamil is not a good choice because of its effect of lowering blood pressure. Intralesional injection of verapamil is also suboptimal because of the required frequency for injections. Topical silicone gel combined with verapamil does not lead to systemic hypotension, is convenient to apply, and shows enhanced results. Steroids A long-term course of corticosteroid injections into the<unk>  may help flatten and soften the appearance of keloid or hypertrophic<unk> s. Topical steroids are ineffective. However, clobetasol propionate can be used as an alternative treatment for keloid<unk> s. Topical steroid applied immediately after fractionated CO2 laser treatment is however very effective (and more efficacious than laser treatment alone) and has shown benefit in numerous clinical studies. Surgery acne (left), and photo one day after<unk>  revision surgery: The area around sutures is still swollen from surgery.<unk>  revision is a process of cutting the<unk>  tissue out. After the excision, the new wound is usually closed up to heal by primary intention, instead of secondary intention. Deeper cuts need a multilayered closure to heal optimally, otherwise depressed or dented<unk> s can result. Surgical excision of hypertrophic or keloid<unk> s is often associated to other methods, such as pressotherapy or silicone gel sheeting. Lone excision of keloid<unk> s, however, shows a recurrence rate close to 45%. A clinical study is currently ongoing to assess the benefits of a treatment combining surgery and laser-assisted healing in hypertrophic or keloid<unk> s. Subcision is a process used to treat deep rolling<unk> s left behind by acne or other skin diseases. It is also used to lessen the appearance of severe glabella lines, though its effectiveness in this application is debatable. Essentially the process involves separating the skin tissue in the affected area from the deeper<unk>  tissue. This allows the blood to pool under the affected area, eventually causing the deep rolling<unk>  to level off with the rest of the skin area. Once the skin has leveled, treatments such as laser resurfacing, microdermabrasion or chemical peels can be used to smooth out the<unk> red tissue. Vitamins Research shows the use of vitamin E and onion extract (sold as Mederma) as treatments for<unk> s is ineffective. Vitamin E causes contact dermatitis in up to 33% of users and in some cases it may worsen<unk>  appearance and could cause minor skin irritations, but Vitamin C and some of its esters fade the dark pigment associated with some<unk> s. Other * Cosmetics; Medical makeup can temporarily conceal<unk> s. This is most commonly used for facial<unk> s. * Dermabrasion involves the removal of the surface of the skin with special equipment, and usually involves a local anaesthetic. * Massage has weak evidence of efficacy in<unk>  management. Any beneficial effect appears to be greater in wounds created by surgical incision than traumatic wounds or burn wounds. * Microneedling
