Dear doctor , I have been diagnosed with thyroid since 1 yr I'm on thyronorm 25mcg tablets , since then my face has darkened compared neck , I got hair growth on chin n upper lip and stubborn dark circles .I'm really worried I'm following a balanced diet as well , I have tried facials but still no results .All possible home made packs as well .What is permanent solution for this and I have never done threading to my face so can threading be a good option for unwanted facial hair ?
