Here are some causes of dry skin:
Medication Side Effects
As a society, we have increasingly become dependent on medication for things like high blood pressure, tension headaches, and even depression. Skin care treatment for dryness may very well be necessary due to some side effect of your medication for a completely unrelated condition. For this reason, you always want to monitor any potential skin irritation immediately after starting any new medication. If you already have dry skin and can’t remember whether or not it was a problem before starting your medication, you may need to consult with your physician and discuss an alternative medication in order to rule out side effects as the cause of your dry skin.
Skin care problems are often the result of poor nutrition. Our bodies require a delicate balance of nutrients in order to keep everything functioning properly, especially the skin. Vegetarians and vegans often run into dry skin issues as a result of not consuming enough animal fats in their diet. A vitamin B12 deficiency will cause your oil glands (sebaceous glands) to function improperly, generally leading to acne.
