In the skin

Deep localized inflammation damages supporting skin tissue. Healing leaves a narrow, deep tract-like depression in the surface.

Inflammation destroys localized supporting tissue beneath the surface. Healing leaves a depression with more defined edges than a broad rolling scar.

Daily care

Habits that help

  • Use broad-spectrum SPF 30 or higher on healed exposed skin
    Sun protection helps limit persistent color changes around scars.
  • Keep healed skin comfortable with gentle cleansing and moisturizer
    These measures support the skin barrier but cannot reliably lift established depressions.
  • Control active acne or inflammation before elective scar procedures
    Ongoing lesions can create new scars even while older ones are being treated.
  • Use photographs in consistent light to track change
    Scars change slowly; compare over months rather than repeatedly inspecting each day.

Avoid

  • Avoid: Picking new spots, crusts or healing wounds
    Repeated injury increases the chance of further marks and scarring.
  • Avoid: Home needling, deep peels or cutting scar tissue
    These can worsen scarring or cause infection, especially before a wound has fully healed.

Depth-specific scar treatment

Listed

Selected scars may benefit from resurfacing or punch techniques; depth and skin tone guide the choice.

Outlook

Long term

Narrow deep scars usually persist without scar-directed treatment. Selected focal procedures can improve them, but several sessions may be needed and complete clearance is unlikely.

Boxcar scars generally persist, although their appearance can improve with appropriately selected procedures. Scar depth and edge shape influence treatment, and complete removal is unlikely.

Complications

Possible complications

Scars can affect confidence; symptoms and treatment options depend on scar type.
