Hydration is crucial for maintaining the health and appearance of the skin. Heat induces perspiration, a natural phenomenon aimed at rebalancing body temperature. However, excessive sweating due to high temperatures can lead to skin dehydration and thus weaken it. Discover our advice for keeping your skin hydrated in case of high heat.

The importance of skin hydration during periods of intense heat.
Hydration is crucial for maintaining healthy skin. However, the skin's water requirement varies from one season to another, particularly during the summer. When the summer season arrives, temperatures are on the rise, which promotes perspiration and leads to skin dehydration.
During periods of intense heat, the skin is assaulted by a combination of factors such as rising temperatures, UV rays, wind, sand, etc. This leads to a rapid loss of hydration, causing the skin to become dry and fragile. A poorly hydrated skin during a heatwave will become dry, sensitive and prone to feelings of discomfort.
In response to temperature and sunlight, the skin tends to thicken. Indeed, UV rays lead to a hyperkeratinisation process, which is an overproduction of keratinocytes resulting in a thickening of the epidermis. This hyperkeratinisation prevents the evacuation of sebum, which then clogs the skin's pores and promotes the appearance of spots. Sebum production increases, causing an alteration of the hydrolipidic film which no longer plays its role as a protective barrier. As a result, the epidermis loses hydration. It is therefore necessary to compensate for this water loss by regularly and properly hydrating your skin, especially when it accumulates impurities from sweat, sebum, and makeup.
The steps to follow for hydrating the face during intense heat
In order to prevent skin from drying out, it should be regularly moisturised. Facial skin requires particular attention, as it is slightly thinner and more sensitive compared to the rest of the body.
The cleansing.
Before applying any particular treatment, the skin must first be cleansed. Whether it's morning or evening, the facial skin will have accumulated impurities, sweat, and excess sebum. A gentle makeup remover should be used so as not to further irritate the skin, given that it is exposed to heat and UV rays.
The application of moisturising treatments.
With the perspiration caused by high temperatures, it is necessary to use moisturising treatments to counteract the water loss that is exacerbated by intense heat. To boost your skin's hydration, you can apply our hydrating serum daily. It is composed of 3% hyaluronic acid (INCI: Sodium Hyaluronate) known for its highly hydrating virtues (it can retain up to 1,000 times its weight in water), as well as 2% pro-vitamin B5 (INCI: Panthenol) which reduces insensible water loss. To seal in hydration, it is important to nourish your skin to strengthen the skin barrier and prevent transepidermal water evaporation. Thus, apply our nourishing face cream morning and evening. It is composed of hyaluronic acid and shea butter (INCI: Butyrospermum parkii butter) which has soothing and nourishing properties to protect the skin from dryness and external aggressions.
Drinking water.
Skin hydration also comes from within. Generally speaking, it is important to drink 1.5 litres of water per day, and this is essential during periods of high heat, particularly during a heatwave. You can also favour foods rich in water such as cucumber, watermelon, melon, lettuce, tomatoes, radishes...
Frequency of facial hydration.
During periods of intense heat, facial skin needs to be moisturised approximately twice a day, in the morning and evening. The morning application prepares the skin to face the day and helps it maintain its hydration throughout the day. In the evening, after being cleansed of makeup, the skin needs to be moisturised again to support the cellular renewal process that occurs during sleep.
