How to distinguish between dry skin and dehydrated skin?

Dryness is a skin type. The term "dry" is actually inaccurate, as it implies a lack of hydration, hence a lack of water. However, skin that we describe as "dry" is in fact what we call "alipidic" skin, meaning it is lacking in lipids . Due to insufficient sebum production, the barrier function of the hydrolipidic film is weakened, which makes the epidermis more susceptible to external aggressions and facilitates the evaporation of the water contained within the skin.

However, while it is impossible to change the nature of an alipidic skin, we can nevertheless recreate the protective film on the surface of the epidermis and on the body, and thus combat skin dryness, thanks to nourishing treatments and penetrating ones such as thevegetable oil of argan or plum, or even the nourishing serum enriched with olive squalane. The latter has a structure very similar to sebum and therefore has an excellent affinity with the skin. You can also rely on the relipidating serum with ceramides and aloe vera. Ceramides are lipids naturally present in the interlipid cement allowing the cohesion of skin cells. They help to strengthen the skin barrier and fight against possible dryness.

Dehydration is a sporadic issue. Skin is referred to as "dehydrated" when it lacks water . Therefore, you can indeed have oily, combination or normal skin and still lack hydration. A nourishing cream or oil will not alleviate a dehydrated skin , unlike a treatment rich in hydrating active ingredients capable of retaining water and preventing its evaporation.

The hydrating serum concentrated in hyaluronic acid precisely helps to retain water in the skin. Derived from the fermentation of wheat, this molecule is known for its highly hydrating virtues and can retain up to a thousand times its weight in water. It allows for instant hydration but also the maintenance of hydrated skin over time. The daily intake of hyaluronic acid also helps to reduce the appearance of fine lines and make the skin more supple and toned. You can complement it with the 9-ingredient face moisturising cream . It notably contains hyaluronic acid and glycerine, two humectant active ingredients, which will help to seal the skin's hydration.

Conclusion? A state of dehydration is therefore not necessarily associated with a dry skin. However, dry skin often leads to a state of dehydration.
