Temperature fluctuations, overly hard water... the skin deserves all the necessary care to stay healthy in the face of various external aggressions. Hydration is among the essential care, regardless of the skin type. To avoid weakening the skin, this step should not be overlooked. Let's focus.

Facial Hydration: What does it entail?
The skin endures various daily assaults such as wind, heat, cold, and pollution. These aggressors weaken the epidermis, accelerate skin aging, and render the skin dull. To enable the skin to protect itself, hydration is essential. Carried out after skin cleansing, this step helps to restore the skin's hydrolipidic balance. It contributes to the skin's cellular regeneration. Besides drinking at least 1.5 L of water per day, the use of a moisturizing cream is necessary to hydrate the skin. In conjunction with the stratum corneum, this care creates a protective barrier composed of water and fatty substances on the skin's surface. By retaining moisture, this protective film thus spares the skin from external aggressions.

Neglected Facial Hydration: What are the Risks?
Water is essential for the proper functioning of skin renewal. However, its deficiency can lead to skin dehydration. If we do not regularly rehydrate our skin, it becomes exposed and weakened by external aggressions, thus risking losing its smooth, toned, and plump appearance. Moreover, over time, this phenomenon can cause other consequences:
The formation of wrinkles on the face, due to the alteration of the hydrolipidic film that protects the skin.
Poor hydration also leads to the drying out of the epidermis, which becomes irritable. Furthermore, it becomes prone to itching and tightness.
In cases of dehydration, the cells of the epidermis tend to whiten, thus resulting in a dull complexion.
When hydration is neglected, the skin of the face ages prematurely.
How to properly hydrate your face?
To prevent your facial skin from becoming dehydrated, you should use a moisturizer suitable for your skin type both morning and night. Moreover, it is generally necessary to take into account the temperature variations your skin will be exposed to, hormonal fluctuations, or even changes in seasons.
For a cream suitable for all skin types, you can opt for the 9-ingredient moisturizing cream. Light and non-greasy, this skincare product is suitable for dry, combination, normal, and sensitive skin. However, it is not recommended for oily skin. This treatment will provide the right amount of hydration and repair to the epidermis, thus combating dull complexion, tightness, and fine lines.
The goal of a moisturizer should be to ensure that a higher percentage of water remains in the most active layers of the epidermis, that is, to mimic the physiology of the skin's lipids.
If the percentage of water in the air is low (low humidity) or if the skin is dry and dehydrated, leading to rapid transepidermal water loss, the cream chosen for daytime use should create a barrier that slows down transepidermal water loss. It should be composed of a combination of occlusives, emollients, and humectants with film-forming properties.
If the humidity is high and the skin type is combination or oily, the opposite applies. It is preferable to recommend a lighter water-based gel/cream formula or an oil-free formula with a different variation of humectants. Occlusive products are not recommended for daytime use. The emollients contained in the moisturizer should not be comedogenic and the percentage should be reduced to a minimum.
