Hello,
Black sots on the face and necks are commonly due to over-exposure in the sunlight,
hormonal problems, liver issues, excess production of melanin, deficiency of vitamin B9, B12 and
vitamin C. To get rid of dark spots you can apply skin lightening creams (
hydroquinone creams and serums), products containing Retin A and Renova also work well by exfoliating skin and promoting new healthy skin growth.
You are suggested to visit a
dermatologist laser treatment and peels are equally effective. Avoid exposure to sunlight, always wear sunscreen, avoid oily, spicy food. Take food that is easily digestible to detox your liver. Take balanced home made nutritious food and avoid addictions if any.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
