hello dear dr

ive been searching for a way to get rid of my brown ''lip vermillion border'' .
well i have been doing many stuff to eliminate this pigmentation and i guess what i have is genetic since i do not even smoke , and i dont think its cause of sun exposure cause it has been years ive been applying UV protection on my lips, out door, any way.. now im thinking about doing a laser treatment but i need to be sure of consequences and probable dangers , or .. side effects or i dunno , all the aspects , since i hear lips are very sensitive and laser can cause uneven color after treatment , scars.. burns... and such !!! and also there are many methods of killing the pigments by laser like : fractional method or yag ! ( which i hear may cause uneven pigmentation and scarring ! ), or q-switched Nd:Yg laser.. which i dunno anything about !
anywayssss, !! , do u think u can help me ?
oh by the way , some times my lips get real dark ! and some time not that much ,, but the inner part is alwaysss pale pink !
