Inflammatory acne causes acne scars. Scars may be pigmented- black/red discoloration, or textural changes - raised or depressed scars that felt by touch. Severe scars are visible at a distance and may not be conpletely coverable by makeup.

Pigmentation fades naturally, but can take months to years. However, the textural change in skin due to actual tissue/collagen defect cannot heal by itself. They remain permanently and can even worsen with age and deteriorating skin quality.

The best way to treat acne scars is by taking action when you have breakouts so that bad scars do not form at all. Maintain a good skincare regimen with mild sunscreen, cleanser and moisturiser. Take healthy diet and avoid stress to naturally improve acne and acne marks. Tea tree oil, aloe vera, rosehip oil can be used to treat acne prone skin and marks. With regular usage they can improve the skin quality.

Once acne scars form, natural remedies cannot heal them completely. Collagen stimulating procedures like microneedling radiofrequency and fractional laser, injections for raised scars, minor surgical procedures etc are recommended by dermatologists for treating textural acne scars. Chemical peels like salicylic acid, lactic acid and mild laser toning can help with acne marks.

You can try natural remedies at early stages of acne or to improve skin quality. But visiting a dermatologist for proper diagnosis and treatment is recommended. Once you understand the mechanism of action for the treatment options, you can decide what you are comfortable with, as they mostly act by improving skin's natural healing capacity without harming the skin.
