Causes of Scarring

One of the most common causes of scarring is injury to the skin from cuts, burns, acne, or surgery. When the skin is damaged, it begins a natural healing process to repair the injured area. As new skin cells form and collagen is deposited, a scar is left behind. Some scarring is inevitable as a natural part of healing, but the severity can depend on multiple factors. Deeper wounds that damage more layers of skin tend to result in more noticeable scarring. Improper wound care can also impact scar appearance.

Types of Scars

There are a few main types of scars based on their appearance:

Hypertrophic Scars - These scars are red, raised, and firm. They occur during the initial healing phase as extra collagen forms. Hypertrophic scarring is more common in wounds with extensive tissue damage.

Keloid Scars - Similar to hypertrophic scars but can grow beyond the border of the original wound. They tend to be rubbery or lumpy in texture. Keloid scarring has a genetic component.

Atrophic Scars - Often appears as pits, dents, or depressions in the skin. This occurs when there is a loss of collagen during the healing process. Common with acne.

Stretched Scars - Forms over flexible areas like the shoulders, back, and chest. They tend to be wide and thin due to tension on the skin during healing.

Treatment Options

For newer scars still in the healing phase, applying creams or gels with ingredients like silicone, vitamin E, or collagen can help improve appearance by moisturizing the skin and reducing discoloration, bumpiness, and width of the scar. Scarring that has fully matured may require more aggressive techniques. Here are some common medical scar treatment options:

Corticosteroid Injections - An anti-inflammatory medication that can flatten hypertrophic and keloid scars. Works best on new scars. Multiple treatments are often needed.

Laser Therapy - Uses targeted light energy to break down excess collagen and flatten raised scars. Common lasers used are pulse dye laser, fractional laser, and CO2 laser. Multiple treatments spaced 4-6 weeks apart achieves best results.

Surgery - Procedures like scar revision or excision can reshape and remove excess scar tissue. Works well for wide, raised scars but surgery carries risks and scarring is still possible. Follow-up care is important.

Injectable Fillers - Substances like collagen or hyaluronic acid can help fill in depressed acne or surgical scars. Provides volume to level out the skin. May require several treatments.

Dermabrasion - A procedure that physically sands or "abrades" away the upper layers of the scarred skin to stimulate new collagen. May help if scars are superficial. Carries risk of infection and bleeding. Results take 4-6 months to see.

Choosing a Treatment

When evaluating scar treatment options, consulting a board-certified dermatologist or plastic surgeon is recommended. They can properly examine the scar, determine the best approach, and manage expectations. Factors like scar type, location on the body, age of the scar, patient characteristics, and desired outcome influence the treatment plan. Combining methods may provide optimal results, such as creams with laser therapy. Maintenance with sun protection is also important to help prevent worsening of scarring over time. With the right mark treatment, appearance can often be improved.
