In summer, when temperatures rise, heat spots can appear. What is it exactly? And how to make them disappear? A dermatologist responds.
Heat pimples are benign little pimples that can be red and itchy or simply translucent. They can occur at all ages, but are more common in children and young adults.
They often occur in summer, especially in tropical or humid climates, or after an episode of fever. At the origin of these buttons? Excessive and unusual sweating.
Sweating can be aggravated by occlusive beauty products such as sunscreens or over-rich oils, but also by wearing synthetic garments and plastic mattress covers.
The heat spots usually appear at the level of the trunk, and more particularly the back and folds of the body. These specific areas help to differentiate heat spots from other forms of rashes, such as summer lucite for example.
Escaping heat and humidity
To avoid heat spots, there is no secret: you have to flee the hot and humid atmospheres!
How? 'Or' What ? By ventilating rooms in which one sleeps, wearing loose clothing, avoiding synthetic materials and limiting the use of creams too rich, which may clog the pores mechanically.
Exfoliating the skin regularly can also be useful, either mechanically with a brush or scrub, or chemically with a moisturizing exfoliating cream with urea or fruit acids for example.
In children, other precautions are necessary: during a long car trip, maceration due to car seats can cause excessive sweating and heat sores. To avoid it, it is advisable to check if they are not too covered and to offer them water regularly.
A motto: hydration!
Whether to prevent or to remove heat sores, the first reflex to have is to avoid hot environments and cool the room in which we sleep, to limit perspiration.
Who says perspiration says need of hydration! To treat the heat buttons, it is therefore necessary to increase the influx of water. Other solutions may also be proposed depending on the type of button.
Heat spots that look like small transparent vesicles disappear spontaneously after a day or two, when exposure to heat stops. The skin then starts to peel finely.
When heat pimples are inflammatory, the itching is usually more stubborn. A soothing and restorative cream, a corticosteroid cream or an antihistamine can then be used.
