Skin types vary from one person to another: oily skin, dry skin, sensitive skin or combination skin. Each of these skin types can be affected by dehydration. This condition is temporary, unlike skin type which is often permanent. In other words, due to various factors, everyone is likely to experience skin dehydration at one point or another. But how can one identify the signs related to skin dehydration?

Water in the skin, in short.
The skin is an organ composed of three layers: the epidermis (the most superficial), the dermis, and the hypodermis. It contains 30% of our body's water and is itselfmade up of an average of 70% water. The dermis contains 80% water. It is stored in the form of a gel thanks to hyaluronic acid which retains water molecules like a true biological sponge. At the dermis-epidermis junction, this concentration rises to 70%. At the level of the stratum corneum and the upper layer of the epidermis, water is present at 10%. As a reminder, the stratum corneum is the most superficial layer of skin, composed of dead cells (corneocytes).
What are the signs of skin lacking in hydration?
A dehydrated skin is due to a failure in the hydrolipidic barrier which is no longer able to retain water. This recurring but temporary and reversible phenomenon is often linked to environmental factors (cold, wind, pollution, sun, etc...), stress, fatigue, lifestyle (smoking, insufficient hydration, alcohol consumption, use of overly aggressive/abrasive cosmetic products) and the intake of certain medicinal treatments (anti-cholesterol, anti-acne, etc...). Skin ageing is an intrinsic factor that also promotes dehydration due to the drastic drop in hyaluronic acid it causes over the years.
Several signs can be identified to detect a state of skin dehydration:
A loss of radiance and comfort ;
Feelings of tightness, particularly after cleansing or showering;
More pronounced fine lines, typically on targeted areas of the face (corners of the eyes, cheeks, forehead) ;
Flakes of skin (small dead skin cells) that appear after applying makeup;
An excessive production of sebum. Indeed, to combat this lack of water, the skin deploys defensive measures. It increases the secretion of sebum in order to strengthen the protective barrier. Hyperseborrhea then promotes the development of bacteria responsible for imperfections. A dehydrated skin can therefore present acne spots, blackheads or closed comedones. Thus, oily skins with imperfections can also be subject to episodes of dehydration which will only worsen their condition!
Tip : To determine if your skin is dehydrated, pinch a small part of your cheek. If it wrinkles, your skin needs to be hydrated.
What should I do if my skin is dehydrated?
The first step in rehydration involves drinking enough water throughout the day. This helps to clarify the complexion. Then, during one's skincare routine, it is crucial to rely on formulas rich in humectant ingredients (glycerine, hyaluronic acid, aloe vera, etc...) that will retain water in the skin layers. Here is a Typology routine suitable for dehydrated skin.
Cleaning one's skin.
Morning and evening, opt for a gentle and non-drying cleanser like our hydrating milk with chamomile extract. Enriched with hydrating active ingredients, this skincare product removes impurities and cleanses the skin without damaging its hydrolipidic film. After use, rinse your face thoroughly with clean water.
Rebalance the skin's pH.
Thehydrating toner will rebalance the skin's pH, while eliminating any limestone residues present on the face. Concentrated in hyaluronic acid and aloe vera, this lotion helps to rehydrate the skin and reduce feelings of tightness. It is only after these initial steps have been carried out that targeted anti-dehydration treatments can be applied.
Hydrate.
Hyaluronic acid is the key compound for hydrating your skin. This active ingredient acts like a molecular sponge: it is capable of retaining up to 1,000 times its weight in water. Morning and evening, on clean and dry skin, apply the hydrating serum based on hyaluronic acid and provitamin B5 followed by the 9-ingredient hydrating face cream. These treatments compensate for the natural decrease in hyaluronic acid in the skin, resulting in hydrated, plump and smoother skin.
