Spots and Scars on Legs and Thighs: Will Skin Peeling Remove Them?

Spots and scars on legs and thighs.
The legs very easily hyperpigment due to trauma, insect bites and the like. Often what looks like scarring is just "postinflammatory hyperpigmentation" which is pigment that occurs with skin healing. This problem can take a great deal of time to resolve. I prefer to avoid any aggressive peels or laser treatments because of the risk of additional postinflammatory pigmentation as a result of the procedure. You might consider one or more of the following: a retinoid (differin, retin-a), a low potency corticosteroid cream, hydroquinone.
Pigmentation from bug bites/scratching
The problem you have is called "post inflammatory hyperpigmentation", and is a very difficult problem to fix particularly on the legs. Pigmentation in this area can often last 2 years or longer. First of all, every time you get a bite, apply hydrocortisone and a bandaid to keep from scratching. For the spots that are already there, and are healed, try a prescription cream, hydroquinone, just to the spots twice a day. You can also use a glycolic acid containing moisturizer on the entire leg which will help the spots slightly. I don't believe peels or laser procedures help significantly with post inflammatory hyperpigmentation. However, if you decide to give it a try, make sure you go to an experienced physicians office because it is very easy to injure legs (as you have learned).
Hope that helps.

Pigmentation on legs
I love the responses from the other dermatologists and completely agree with their opinions on this challenging condition. I usually recommend a lotion containing some type of mild exfoliatiant such as glycolic acid, salicylic acid or urea or a combination of those. Tretinoin can also be helpful but is more expensive and can be a bit irritating. I have seen nice results using these creams but it takes a long time - many months.
