Between November and March, one of the most common questions faced by skin care professionals relates to the treatment of dry winter skin. After all, it’s a condition to which few who live in Northern climates are immune. In fact, according to a report from the National Health Interview Survey (NHIS), a whopping 81 million Americans claim to experience dry, itchy or scaly skin during the winter months.
Given the prevalence of the condition, also known as “winter itch,” it is imperative that skin care professionals are prepared to combat the problem. Of course, providing clients with tips to improve the symptoms of dry winter skin is vital, but to ensure the recommendations you provide are those that will make a discernible improvement in a client’s skin, it’s necessary to have a sound understanding of the cause of the condition. What’s more, by presenting your clients with the reasons why they are enduring the discomfort of winter itch, they will be more likely to diligently implement your recommendations for how to remedy it.
