Remove Scars from a Lip Lift?

The scar tissue itself is difficult to "reverse", (you can try massage), but the white color can be treated by a permanent make-up tattooist that has been trained in this. Surgeons whom do breast reconstruction work with these tattooists to "color" reconstructed nipples, and you should be able to get a referral by asking one of them for a recommendation.

 There is no way to "remove" a scar - they are permanent.  Vigorous massage would be the first line treatment with no downside.  Steroid injection can help but can also atrophy the normal fat making dents.  Lasers are ineffective in this setting.  Try massage!

You have not told us exactly where the scar is and what is the problem with the scar. You have to understand every time we get a cut deep enough, we will heal by scarring. Sometimes a scar revision may improve the scar. If the scar is thick, steroids can help. Some lasers such as laser resurfacing can help if you have the right skin color.

There is no way to remove a lip lift scar, but it can be softened. Consider first a dilute steroid injection, then if that doesn't help, consider fat injections. It is not a fat injection to make the lip bigger, but using a small cannula to break up the scar and inject the gap created with small droplets of fat. Hope this helps!

Generally there are few lasers that will helpt to soften scars. Triamciniolone injections may soften the scar but also result in atrophy or redness, I would enourage stretching and scar massage and contemplate skin needling as an option. Topical silicone gels may help but it may be late for that intervention. In regards to the white scars, you could consider permanent micopigmentation as an option.
