How to tell the difference
Look at the skin from the side in daylight and run a clean finger over it. A mark is flat, and only the colour is different. A scar has a changed surface: a dip you can see in side light, or a raised bump. Many people have both at once.
- Acne mark
- Flat, darker than the skin around it. The texture is normal
- Acne scar
- A dent or a raised bump. The texture has changed
What helps acne marks
Marks need sun protection and time. Dermatologists say treating dark spots begins with sunscreen, ideally tinted with iron oxide. A spot a few shades darker than your skin usually fades within 6 to 12 months. Gentle products help too, because irritation itself can cause new dark spots.
- Wear sunscreen every day, because sun keeps marks dark
- Switch to gentle products if anything stings or burns
- Keep treating the acne, since new pimples leave new marks
- Be patient: months, not days
What helps acne scars
Skincare cannot rebuild a scar, so be wary of any product promising to. Dermatologists offer in-clinic treatments, including microneedling and acne scar surgery, and which one suits you depends on your scars. Treatment starts with a consultation, and the first step is getting active acne under control.
See a dermatologist if your acne is deep or painful, or if it is leaving dents. Treating acne early is the best protection against new scars.
How to avoid new marks and scars
Do not pick, pop or squeeze pimples: doing so increases your risk of getting a scar. Use a gentle routine, avoid products that irritate, and wear sunscreen every day so that the marks you do get fade faster and do not darken further.
Get a routine for your own skin
Saundarya AI is an AI skin analysis and grooming app that reads a single selfie and returns a personalised report: face shape, skin type, detected skin concerns with the visual evidence behind them, a morning and night skincare routine, product picks at three budgets, and an 8-week improvement plan.
Generic advice is a starting point. A scan reads post-acne marks and where they sit on your own face, shows the visual evidence and a confidence score, and builds a morning and night routine around it. The first full analysis is free.
This is general cosmetic guidance, not medical advice. See a dermatologist for skin that is painful, spreading, scarring or not improving after 8-12 weeks.
