When acne breakouts penetrate the skin deeply, they damage the skin and the tissue beneath it. As the acne clears, the body tries to repair this damage. During the healing process, the body progresses through inflammation, tissue formation and matrix remodelling .At the end of this process the body produces collagen—a substance that gives the skin support. If the body produces too little or too much collagen, you will see a scar. The type of scar depends on how much collagen your body makes.
Depressed acne scars: This is also known as Atrophic scars. Atrophic scars are most common on the face. A depressed scar sits below the surrounding skin. They’re formed when not enough collagen is deposited while the wound is healing. If the body produces too little collagen, depressions or pits form as the skin heals. Atrophic scars can occur as icepick, rolling and box scar.
Raised acne scars: This is also known as Hypertrophic scars or Keloid. These scars are most common on the chest and back. They stand above the surface of the surrounding skin and are caused by too much collagen during healing. Sometimes the body produces too much collagen as it tries to heal the skin and underlying tissue. When this happens, a person develops a raised acne scar.
The following types of scar occur in acne:
Atrophic scars – flat, thin scars or depressed scars . They can occur as
Raised acne scars
Laser Resurfacing: laser resurfacing is meant to resurface skin cells as a means to treat acne scarring, sun damage, fine lines, and other skin issues. The lasers create tiny wounds on the face which then stimulate collagen production to smooth out and tighten the skin.
Dermabrasion: it utilizes a machine driven source to remove upper layers of skin it is best used for well define scars.it helps in new collagen formation
Chemical Peels: chemical peels are used to treat depressed scars.they induce tissue injury that stimulates collagen deposition .they are categorized as superficial,medium and deep peels depending on the depth of penetration in the skin .depending on the type of scars the type of peel of different concentrations are selected
Microneedling or Dermaroller: this technique utilizes tiny needles to puncture the skin multiple times initiating wound healing leading to collagen deposition in upper layers of skin. It can be combined with certain meso solutions or platelet for better results.
Microneedling Radiofrequency: radiofrequency delivers thermal energy through the insulated microneedles in dermis and hence helping in collagen remodelling
Scar Revision: Scar revision surgery will attempt to minimize a scar so that it is less conspicuous and blends in with the surrounding skin tone and texture. Scar revision is minor surgery performed under local anesthesia to improve the appearance of a scar anywhere on your body.
Dermal Fillers: Dermal fillers can be used to treat depressed acne scars. Dermal fillers will help to raise the indentations and volume loss caused by acne, creating a smoother appearance. Dermal Fillers exhibits highly favourable results in refining the appearance of acne scars by lifting the indented, depressed scars.
Acne scars can be prevented by early effective treatment of acne and till to date is the most effective treatment approach
Treatment of acne scars is a staged process by combining various modalities and depends on severity of the lesions,type of the lesions,downtime of interventional methods and patient expectations.treatment of acne scars involves multiple sessions and combination of different treatment modalities to give the best possible result.
Acne breakouts can be frustrating, and they can also leave scars on the face and other areas of the body. Some people find that acne scars are an unwanted reminder of a painful and bothersome condition. However, acne scars do not have to be permanent, as some medical treatments can help in reducing them.
