If I apply anything on my skin- like moisturizer or makeup or lipstick. I don't eat it.. my mouth tastes weird or bitter in few seconds and my head feels heavy and feel nauseous and that feeling is there for hours. I don't know what to do. I have acne , I cant hide the dark spots or apply acne face wash or any cream. I tried so my products,  either tastes weird or my eyes burns/water eyes..  Since 2 years I have this problem.Also my face skin became tanned or darker  than my body skin. Tried ayurvedic /herbal products also. Tried many doctors they say dust allergy, I am on immunotherapy. But not much difference in mouth tastes. I have constipation, acidity, gastritis, imbalances prolactin, I am working on it in a holistic way. I am not on any medications. I understand I have super sensitive skin. Some how cetaphil cream works. But nothing else. Please help me with the reason. Tired with this now.
