How do I reduce redness in a scar?

There are many options for scars including vascular lasers, microneedling, fillers and scar gels.  Please post photos and see an expert.  Best, Dr. emer.

For up to 3 months post operatively, you can apply a scar gel .  I recommend to my patients, a scar gel called bio-corneum.  It has silicone and an spf mixed in the gel.  Avoiding sun,tanning, etc will also reduce permanent redness/darkness at scar as well.

Microneedling can be helpful but a consistently good treatment for red scars is the pulse dye laser which can lighten this scar and flatten it in one session.

Usually the most reliable approach is to treat with pulsed dye laser.  It generally takes more than one treatment session to see the best results.  For at home treatment, it often helps to use silicone gel sheeting or another type of silicone product.
