Hello, Thanks for your query.Often, changes with pigmentation are among the most pronounced skin changes during pregnancy. The area around your nipples might darken. The same thing can happen with the skin on your inner thighs and genitals. You might notice a dark line from your navel to your pubic bone. Dark patches might develop on your face, particularly along the cheek bone and upper lip. This is known as chloasma or mask of pregnancy. Although these skin changes aren t preventable, chloasma can get worse with sun exposure. Stay in the shade when you can. If you must be in the sun, use plenty of sunscreen. Why don t you try some alternative medicine like homeopathy, as there is no clear treatment for the same in allopathy. I hope this information has been both informative and helpful for you. In case of any doubt, I will be available for follow ups. if you like my answer kindly rate my answer and write a review as well. Thank you, Wish you good health.
