Hi XXXXXXX,
Welcome to XXXXXXX forum.

Kindly attach the picutre of affected skin area,if possible.
With the available described information, There appears tobe possibility of "Melasma".
Melasma is dark tanning of skin in females, mostly during pregnancy or in those women who are taking oralcontraceptive pills or on hormone replacement therapy.

Melasma is due to the stimulation of melanocytes (pigment producing cells) by the female sex hormones estrogen and progesterone to produce more melanin pigments when the skin is exposed to sun.
Women with a light brown skin type who are living in regions with intense sun exposure are particularly susceptible to developing this condition.
The incidence of melasma also increases in patients with thyroid disease.
Overproduction of melanocyte stimulating hormone (MSH) brought on by stress can cause outbreaks of this condition.

You should consult with XXXXXXX medicine specialist/ dermatologist and should go for skin examination.
Melasma is usually diagnosed visually or with assistance of a Wood's lamp (a special type of lamp).
Your thyroid profile must be in controlled range.
As such there is no correlation between blood pressure, cancer strokes and melasma.

The discoloration usually disappears spontaneously over a period of several months after giving birth or stopping the oral contraceptives or hormone replacement therapy.
You should take hydroquinone, isotretinion and azeliac acid ointment on written prescription and should apply twic in day.
You should also apply sunscreens lotion for better protection.
Improvement is gradual and takes time for recovery.

Hope that helps.
Let me know if I can address any more concerns.
Take care,
Dr. Mayank Bhargava
