Dry skin undergoes a weakening of its barrier function. This is due to a change in the skins cellular cohesion, an insufficiency in NMF or natural moisturising factor, and a deficiency in its lipid production.
No, without a doubt dry skin does require nourishment. However, the more oily textures are not necessarily the most effective. What is more, they leave unpleasant qualities after use. Dermatology and dermocosmetics is now determined by the patient’s lifestyle and personal experiences. It is better to focus on a treatment that, while restoring the skin barrier, is also comfortable to use: absorbing immediately, leaving no greasy, sticky film over the skin, and facilitating easy use into our day to day lives.
The skin actually tends to become much drier in wintertime. The cold, the wind, too much heating, and the indoor and outdoor differences in temperature are all factors which aggravate and dry out our skin. If you feel that the condition of your skin varies according to the season, consider using richer formulas in winter such as NUTRITIC Intense Riche.
