What are the risk factors for atrophic scars?

An atrophic scar appears lower than the surrounding skin because collagen or deeper tissue was damaged during inflammation or wound healing. Deep, prolonged, or repeatedly disturbed lesions can cause more structural loss than a superficial spot. A family tendency to develop noticeable scars may also influence the final appearance.

Acne can leave narrow pits, wider depressions, or shallow uneven areas. Chickenpox and other injuries may leave isolated indented marks. A dark or red mark without a change in texture is pigment alteration, not necessarily an atrophic scar.

Manage active acne or another skin condition early, keep healing areas clean, and avoid picking or repeatedly traumatising lesions. Use sun protection to limit contrast between a scar and nearby skin. Do not apply aggressive acids, home devices, or needles to an open or inflamed area.

Once the skin is fully healed, a dermatologist can classify the depression and discuss options. The plan may differ for narrow pits, broad depressions, pigment change, or ongoing acne. Several approaches may be considered, so an examination matters.

Seek assessment if new indentations are appearing, acne is deep or painful, a scar is itchy or tender, or the area is red, warm, swollen, or draining. Prompt review is especially useful when the original wound or rash is still active, because treating inflammation may limit additional damage.

Ask what caused the indentation, whether active inflammation remains, which scar type is present, and when a treatment can be considered safely for your skin.
