How can you tell whether a pimple may leave a scar?
You usually can’t tell with certainty while a pimple is still healing. However, a deep, painful bump—such as a nodule or cyst—is more likely to scar than a small surface-level whitehead or blackhead. Inflammation that lasts a long time, repeated breakouts in the same spot, and squeezing or picking can also raise the risk.
Look at the skin after the blemish has healed. A lasting indentation or a raised, firm area may be an acne scar. A flat red, purple, or brown mark is more often a temporary color change rather than a true scar. These marks can take weeks or months to fade, especially without sun protection.
What can you do to lower the chance of scarring?
Leave the pimple alone as much as possible. Picking and squeezing can push inflammation deeper and injure nearby skin. Wash gently, avoid harsh scrubs, and use a non-comedogenic moisturizer and broad-spectrum sunscreen with SPF 30 or higher. Sun exposure can make post-acne marks look darker and last longer.
For mild breakouts, an over-the-counter product containing benzoyl peroxide or salicylic acid may help when used according to its label. Start with one active ingredient at a time to reduce irritation. A hydrocolloid patch can discourage touching a surface-level blemish, but it won’t treat a deep cyst.
When should you ask a dermatologist?
Consider professional care if you have deep or painful breakouts, frequent new pimples, or marks and indentations that keep appearing. Early treatment can help control acne and reduce the risk of lasting scars. A dermatologist can recommend options suited to your skin and the type of acne you have.

FAQ
Can a flat dark spot after acne be a scar?
A flat dark spot is usually a change in skin color after inflammation, not a texture-changing scar. It often fades gradually, though sunscreen can help keep it from becoming darker.
