my lips are dark in color when i was young like in school they were normal not much pink but not too dark even now i am 23 years old and from last few years i m feeling that my lips are darker now and any lipstick i apply doesnt suite me because of this reason. i went to a skin specialist and she asked me whether i bite my lips from my teeth or not i said may be i didnt give attention on this. but may be when they are dry i lick them. so she gave me depiwhite advanced depigmentation cream, i just wanted to know that it will effect or not? secondly after leaving it will my lips can get more darker or any other side effects? becuase i dont want them to be more darker.

Hi.thanks for your query. You need to know about the causes of dark lips to be taking precautions better. A lot of people have it genetically predetermined, although parents may/may not have it. A frequent cause of non-genetic lip darkening is the use of lipsticks /colored balms/gloss, as these tend to darken the lips over a period of time. So try and not use it too often. If you have to use it, then let it be alleged free and replace them every 2 months. I would advise you to start using medicated lip balms with SPF and to reapply it several times in a day.that helps in reducing further darkening. Definite cream or any others having Comic acid can be used twice a day for lightening of lip color. It usually does not have side effects. However u can check for tolerance of the product by applying it for a short time on the first application. If you have a genetic tendency to dark lips, the pigmentation has chances of coming back after the cream is stopped. U can also opt for mild chemical peels once in 15-30 days to exfoliate better and lighten faster. Take care!
