Hello, I can understand your concern for extremely dry skin since 2 years. It appears from your query that you have got dryness of skin which is known as xerosis. You have not mentioned your age, sex and occupation so that I could have helped you better. In most of the case of dryness it is seen post middle age. In commonly seen condition of the patients it is not bothersome and self resolving condition which most of the times gets better by itself. I can make out that most of your body areas are dry so it requires through examination to rule out any internal cause. In my patients I go for routine blood examination along with hormonal profile including thyroid profile to rule out any cause related to thyroid. In my patients with your kind of condition I suggest them to apply a mild cream containing moisturizing factors to be applied for multiple times a day. It moisturizes the skin and causes retention of water to maintain the skin texture on the better of the side. In most of the patients it is enough and the skin gets properly hydrated to get normal texture. Wear full sleeves cotton clothes and avoid any synthetic garments. All the best.
