Dry skin can manifest itself for multiple reasons. People with flaky, tough, cracking or dry skin do not necessarily have the same skin condition. If dry skin is a consistent problem, it is best to consult a board-certified dermatologist to find the cause and treatment solution.
Common causes include strong soaps, long showers with hot water, dry weather, itchy clothing and misapplication of moisterizer. There are many different types of moisterizer. The type of moisterizer and the timing of its use are critical for effective treatment of dry skin.
Other causes of dry skin can actually be medical, including psoriasis, diabetes, hypothyroidism, malnutrition, and the side of effects of medication. Due to the complexity of treating dry skin, it is best to consult with a dermatologist.
