The last month is long. I don't know what disease it is. It's not painful or itchy. I'm not sure if it looks like ringworm. What disease is it and what medicine should I use?
In this case of hand skin, you should still pay attention to the effective treatment and conditioning combined with some local drugs to improve and control the symptoms of this condition. In addition, you should have regular living and eating habits at ordinary times, don't eat some irritating food, but eat light diet and conditioning. You can apply tacrolimus ointment or triamcinolone acetonide cream locally.
This condition is considered to be dry eczema. Triamcinolone acetonide econazole cream can be applied externally, once in the morning and once in the evening. Try not to touch soap, hand sanitizer, detergent, washing powder, etc. when working, you can wear gloves. Usually wipe some hand cream. Try to eat less spicy food. Need a light diet.
Your situation is not like a skin problem caused by fungal infection or virus infection. It is more prone to chapped skin caused by improper skin care. You can try washing your hands with warm water and wipe some moisturizing skin care products after washing your hands. If it will turn better in about 1 ~ 2 weeks, it won't be a problem.
