You premiere your new strapless top, you take a short walk under the hot summer sun and when you get home you notice your neckline burning. In this, red, itchy and small transparent rash keeps coming out. You have miliaria, a benign condition, usually short-lived, but capable of ruining your day.
This is due to blockage of the eccrine sweat glands, the tiny ducts that sometimes swell, leading to sweating. something as simple as a hot and humid day, a moisturizing cream or a somewhat blocking sunscreen or clothing that is close to the body and doesn’t breathe well (cycling jerseys, for example) can trigger the appearance of these uncomfortable pimples.
They are not serious, but they are quite itchy
It’s normal to be anxious at the thought of an allergic reaction to a cream, but the trigger is a combination of heat and sweat. Once controlled, itching subsides and acne disappears. “There are three types of miliaria,” says Dr. Maria Vitale, dermatologist, medical director. Cantabria Labs. “Crystalline or prickly miliaria, common in newborns and sensitive adults, are small, very fine, transparent vesicles that break easily. They are exposed to heat in areas of friction, such as the trunk, face, and armpits”. If you have a child, it’s easier to put them on their back than to be stuck behind a car seat during long journeys.
A second type, most often, is Miliaria rubra. “They are transparent vesicles that may be accompanied by red, swollen-type eruptions that can itch. They appear in cracks”, Vitale declared. The third type is deep miliaria. “It is the deepening of the sweat glands. caused by blockage.” This is quite rare, although it can occur, for example, in military personnel stationed in very hot areas.
If the reason is in sweating, avoid sweating
It sounds like a truism, but it is this: if the cause is in heat and humidity, then the solution is the opposite. “Sure keep skin cool and dry. To avoid sweating, finding air conditioning or an environment with plenty of ventilation is ideal,” says Aurora Gare, medical director isdin.
Although the first intention is usually to cover them so that they are not visible due to their unsightly appearance, this should not be done exactly as you should avoid the use of extra clothing and thick or greasy ointments”, says Dr. Gare. Look for a lightweight moisturizer, ideally one with soothing ingredients like niacinamide.
Against itching, fresh and dry
Although the moment of redness and itching is quite uncomfortable, but within 24 hours the acne will get better on its own. It will be necessary to use corticosteroids only in the most acute cases. Still, Isabel Carbonell, Regional Director of Training Pierre Fabre, proposes small pharmacy tricks to speed up healing and relieve itching. “The sprinkling of thermal water provides instant relief on the skin. In addition, it is recommended to apply a drying product to the affected area twice a day to avoid maceration and promote epidermal repair. This is the case for Sicalfate + Repair Drying Spray by Avne”, says Carbonell.
Leonor Prieto, Scientific Director la roche poy and Cosmética Activa Espaa, also committed to thermal water. This product is economical and can get us out of more bondage in summers. We can store it in the refrigerator and spray it after sunbathing, especially if there is a solar erythema in cases of mosquito bites or scratches, as it contains naturally soothing, anti-itch and anti-cough ingredients. Huh. “It is applied directly to the skin. If the reaction is very itchy, we can put it in the form of compresses which we will moisten little by little. If the redness and itching persist, I suggest To soothe and condition the skin, use an epidermal repairer (Sicaplast Baum B5) to restore hydration levels and the skin barrier.
There is no problem in bathing, it is better with hot or cold water. When choosing a body gel, a syndicate cleanser with hydrating, softening and soothing properties such as glycerin, niacinamide or thermal water is ideal at this time.
So isn’t it a flax allergy?
Although they look alike, heat and sweats do not cause acne with what we popularly call a ‘sun allergy’. “Sun allergy or intolerance is a very general term that includes solar urticaria and polymorphic light eruption. It is a rash with swelling and a lot of itching when exposed to sunlight. They have an individual tendency to suffer, Which sometimes has an autoimmune basis. However, more and more cases are being diagnosed, probably due to the sun habits that we have acquired over the years”, explains the dermatologist. Andrea Combalia.
It’s as if the skin says ‘we’ve come this far’ and shows its worst home to those who bask around the summer sun after summer. Spending all year indoors and standing outside in the sun and turning brown in a short period of time is another risk factor. “There are also medications that increase sensitivity to the sun, so it’s very important to rule out drugs that may be behind this intolerance to the sun,” says Combalia.
In order not to ruin the summer, there is no other option but to sunbathe slowly and apply a suitable sunscreen. “They should be high or too much sunscreen. It also helps to incorporate oral sun protection with antioxidants”. No one is free from sun allergies, although it is more common in adulthood and in women.
