Pigmentation

Detailed Answer:
Hello

Thanks for the query

Dark lines around the mouth is a common symptom. Here are my suggestions for you

1. Be sure to remove your make up everyday before you fall asleep
2. Apply a good sun screen lotion every single day
3. Wash your face with exfoliating scrub once daily
4. Topical retinol creams have to be applied over the dark lines, apply it once daily. This will lighten the skin significantly in 3 to 4 weeks
5. For faster results I would recommend you to go for 4 to 5 sittings of Glycopeels
6. A less safer but a more effective option would be to use bleach with hydroquinone
7. If all the above steps fail then the only option left would be laser treatment

I hope I was of help, if you have any further queries please get back to me

I wish you good health
