How do I get the color back in my lips? Will a chemical peel achieve this? (photos)

Because the color loss is the loss of melanin from the skin cells that produce it there may be several things to try to restore it.  Latisse (bimatoprost) can cause melanin generation, and can be tried as a topical preparation.  It is also possible to get repigmentation with an Eximer laser.  Lastly, a skin graft, actually from the inside of the mouth, might repigment the skin.

After several years, the pigment will not return  There are some reports of Latisse improving lost pigment when topically applied to fractional laser pixels immediatly after treatment, but I have never seen reports concerning pigment in mucous membranes.  A makeup tattoo artist that works with women post breast surgery tatooing nipples would be the individual to seek for a solution to your problem. It would be worth the search if this problem impacts your self esteem. 

This is your natural skin color.
Skin tattoos to lip may give you a redder color.
