THEn summer we must not only pay attention to the action of the rays but also to the epidermal dehydration, one of the first effects of high temperatures on the skin. Sweat, exposure to excessive heat but also to air conditioning and fans cause greater water dispersion which leads to dry skin.
Furthermore, “together with humidity they can cause vasodilation and worsen or exacerbate problems such as rosacea or couperose”, explains the Dr. Antonio Ascari Raccagni, clinical dermatologist at the Maria Cecilia Hospital in Cotignola and the GVM Care & Research facilities in Romagna.
Skin and high temperatures, how the epidermis reacts
“High temperatures and high humidity levels cause heavy sweating which causes water to disperse contained in the skin resulting in dehydration », explains the clinical dermatologist.
To this are added two other undesirable effects: on the one hand the hyperproduction of sebum with consequent formation of impurities that can be prevented with sebum-regulating creams with antibacterial and soothing action, on the other hand a skin dryness that leads to appearance of cracks and irritation.
Because of this the epidermis should gradually be exposed to heatso as to allow it to activate all the natural defense mechanisms against external agents.
How to remedy dehydrated skin
Hydration is always essential for the skin “Which needs to be regenerated both in the morning and in the evening”.
A regeneration that implies the choice of the correct routine: “In summer, all gel consistencies are suitable, both for cleansers and creams. Their plus is to deeply hydrate without weighing you down. These formulas can then boast purifying and soothing actions when specific for oily skin »explains the expert.
In particular, with regard to the cleansing in the summer it is better set aside the cleansing milk and prefer gel and mousse. “Once a week I also recommend the scrub which removes the superficial layer of the epidermis, cleaning it from dead cells and rehydrating it thanks to the fatty components present in its formula ».
Apricots, watermelons and carrots: moisturizing fruit and vegetables
But the proper hydration also includes proper nutrition. First of all you have to drink a lot. «By evaporating through the epidermis, the water keeps the body temperature constant and avoids sudden changes in temperature».
The basic rules according to the expert? Prefer a diet rich in fresh seasonal fruit such as apricots, melon, watermelon and peaches, and then vegetables such as tomatoes, carrots, lettuce, radicchio and spinach which are rich in minerals and vitamins capable of stimulating the production of melanin ».
