Scar reduction for wounds, surgical wounds, breast augmentation, open heart surgery, trauma accidents, dog bites ect.

Early and effective treatment of acne scarring can prevent severe acne and the scarring that often follows[28] High melanin levels and either African or Asian ancestry may make adverse scarring more noticeable.[29] As of 2004 no prescription drugs for the treatment or prevention of scars were available.[30]
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 scars.[31] Various chemicals can be used depending upon the depth of the peel and caution should be used, particularly for dark-skinned individuals and also including individuals susceptible to keloid formation or those with active infections.[32]

Filler injections
Filler injections of Collagen or ArteFill can be used to raise atrophic scars to the level of surrounding skin.[33] Risks vary based upon the filler used, and can include temporary improvement, further disfigurement, and allergic reaction.[34]

Dermabrasion
Dermabrasion involves the removal of the surface of the skin with specialist equipment and usually involves a local anaesthetic.

Laser Treatment
Non-ablative 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 the standard laser therapy for hypertrophic scars and keloids.[35] This therapy smooths theto the epidermis via contact cooling. Multiple sessions are usually required for a significant reduction idness and improvement in the texture and pliability of hypertrophic scars and keloids.
Ablative lasers such as the carbon dioxide laser or Er:YAG offer the best results for atrophic and acne scars.[36] Like dermabrasion, ablative lasers work by destroying the epidermis to a certain depth. Healing times for ablative therapy are much longer and the risk profile is greater compared to non-ablative therapy; however, non-ablative therapy offers only minor improvements in cosmetic appearance of atrophic and acne scars.[35]

Radiotherapy
Low-dose, superficial radiotherapy is sometimes used to prevent recurrence of severe keloid and hypertrophic scarring. 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.[37]

Semiocclusive Ointments & Pressure dressing
Silicone scar treatments are commonly used in preventing scar formation and improving existing scar appearance.[38] The effectiveness and safety of silicone sheeting for the treatment and prevention of scars is supported by an abundance of clinical studies.
Semiocclusive silicone based ointments [39] are used to speed healing and reduce the appearance of scars and likely work in a similar manner as silicone scar sheets.
Pressure dressings are commonly used in managing burn and hypertrophic scars, although supporting evidence is lacking.[40] These involve elastic materials or gauze which apply pressure to the area. For large scars and particularly large burns, pressure garments may be worn. It is believed that they work by applying constant pressure to surface blood vessels and eventually causing scars to flatten and become softer.[citation needed] Retrospective and ultrasonic studies since the 1960s have supported their use, but the only randomized clinical trial found no statistically significant difference in wound healing.[40] Care providers commonly report improvements, however, and pressure therapy has been effective in treating ear keloids.[40] The general acceptance of the treatment as effective may prevent it from being further studied in clinical trials.

Steroids
A long term course of steroid injections under medical supervision, into the scar may help flatten and soften the appearance of keloid or hypertrophic scars.[41]
The steroid is injected into the scar itself; since very little is absorbed into the blood stream, side effects of this treatment are minor. However, it does cause thinning of the scar tissue so it does carry risks when injected into scars caused by operations into ruptured tendons. This treatment is repeated at 4-6 week intervals.
Topical steroids are ineffective.

Surgery
Scar revision is a process of cutting the scar tissue out. After the excision, the new wound is usually closed up in order to heal by primary intention, instead of secondary intention. Deeper cuts need a multi-layered closure to heal optimally, otherwise depressed or dented scars can result.[43]
Surgical excision of hypertrophic or keloid scars is often associated to other methods such as pressotherapy or silicone gel sheeting. Lone excision of keloid scars however shows a high 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 scars.

Vitamins
Research shows the use of vitamin E and onion extract (sold under Mederma) as treatments for scars is ineffective.[40] Vitamin E causes contact dermatitis in up to 33% of users and in some cases it may worsen scar appearance.[42] Vitamin C and some of its esters also fade the dark pigment associated with some scars.[44]
