For 4 weeks post surgery, your scars are not a concern. Everyone heals differently and everyone has redness to the scars until the scars "mature". This can take as little as a couple of months or as long as a year. Be patient. I don't know of anything that can make the redness resolve quicker. The redness will eventually disappear though.

Healing after blepharoplasty
Totally normal - this is a normal sequence for wound-healing. You will see the incisions fade week by week - and at times they may appear to be more red than others. Typically they fade completely to your skin tone by 4 to 6 months, but this varies person to person. Enjoy your beautiful new lids!
