How to get rid of red marks/scars left from acne without going to a dermatologist?

Difficult . A good aesthetictian at a medical spa can do microbrasions and series of chemical peels. Remaining scars can be filled with a permanent filler.
Very difficult. The redness is usually due to underlying inflammation and increased blood flow to the areas. It takes 16-18 months for this to improve on its own. A non-invasive/non-ablative laser (laser genesis) works well in helping minimize the redness and also improving the texture of the skin and appearance of the scar. It requires anywhere from 2-6 treatments, and the improvement is apparent in 3-6 months.
Difficult... Depends on the depth and color of the scars. For smaller scars you could try a vitamin E lotion. You may actually get more for your money with microderm abrasion or chemical peels.

Could you tell me ways to get rid of red scars left from acne?

Healing scars. When our bodies sustain an injury, the immediate response is inflammation (red, hot, tender swelling). This is the body increasing the blood flow and bringing healing factors to the area and also the veins expand to carry bad stuff away. As healing occurs, new tissues fill in that are different than normal and less elastic. This is a scar. Over time it will fade in color but always be there. Read more...

I suffered from acne years ago and now its less than before but it left some red scars. What should I do to get rid of them and acne my skin is oily.?

Still active. It sounds like your acne is still active even though decreased. Also, the scars are still red which means they are not yet completely mature. This is an excellent time to manipulate the way they heal. I love treating these early scars and active acne with a combination of aggressive tretinoin, chemical peels, microneedling and platelet rich plasma. You should see a skin specialist. Be well.
