The best solutions against dry skin in winter.

The first step in combating dry skin is theapplication of a moisturiser to the skin, immediately after bathing while the skin is still damp, after washing your hands or whenever you feel the need. These treatments help to repair the skin by filling the gaps between the epidermal cells, preventing the degradation of the skin barrier in winter, rehydrating the epidermis and sealing in moisture. This is particularly possible thanks to the three types of key ingredients they contain, which work together to keep the skin hydrated.

Only use gentle, hydrating skincare products that are free from alcohol, essential oils, and fragrances. These ingredients are considered too "harsh" for the epidermis and can further irritate dry skin.

• The humectants that assist in attracting moisture to the outer layers of the skin. These include propylene glycol, glycerine, sorbitol, hyaluronic acid, and lecithin.

• Emollients , such as ceramides, lanolin, squalane, and fatty acids (linoleic acid, linolenic acid, lauric acid), which help to repair the skin barrier by replacing the intercellular lipids of the stratum corneum, thereby promoting the recovery of hydration.

• Another set of ingredients are the occlusives such as silicone, plant waxes, vegetable butters, petroleum jelly, and mineral oils. They help to retain moisture by creating a physical barrier on the skin's surface, without clogging the skin.

The formulation of the product also plays a significant role. Generally, the thicker and "oilier" the moisturising treatment is, the more effective it will be. Therefore, instead of using a moisturising lotion, it would be better to opt for a balm or cream.

With the heating turned on, a warm and dry atmosphere is created which can dehydrate the skin. In addition to incorporating suitable skincare products to keep the skin moisturised, consider placing a humidifier in your home. Its use will help to increase the humidity levels in the air, which proves to be beneficial in preventing and alleviating skin dryness. Humidifiers emit a fine mist into your room to achieve an optimal humidity level between 40 and 60%, ideal for rehydrating the upper layer of the skin.

Ensure that you clean it and change the water daily, as they can be an excellent breeding ground for bacteria.

While it may be tempting to keep your home warm, it is suggested to keep the thermostat at a moderate temperature to maintain an optimal level of humidity in the dwelling. With more humidity in the air, you are less likely to "suffer" from dry skin. Indeed, excessive heat can strip the skin of its moisture.

Alcohol can have diuretic effects , meaning that the body loses more water than usual, which can lead to dehydration affecting the skin. Indeed, this can contribute to making the skin more prone to dryness. However, if you consume alcohol, consider drinking a glass of water between each alcoholic drink to help reduce the risk of dehydration.

For your information, the "National Institute on Alcohol Abuse and Alcoholism" (NIAAA) defines alcohol abuse as follows: more than three drinks per day or more than seven drinks per week for a woman, and more than four drinks per day or more than fourteen drinks per week for a man.

Long, hot baths or showers may indeed be enjoyable and soothing during the winter months, but they can damage the skin's surface by stripping away much of the skin's hydrolipidic film, causing it to lose its hydration more quickly. Limit your time in the shower or bath to a maximum of 5 to 10 minutes, and rinse with lukewarm water (around 37°C).

If you notice the onset of complications or if the measures you are taking provide no relief, consider consulting a health professional.
