These two terms tend to be confused and we often use them interchangeably as if they were identical concepts, but… did you know that dry skin and dehydrated skin do not correspond to the same definition?
When we talk about dry skin we are in a way categorising a skin according to its typology, and a structure with a certain degree of permanence over time. Although we know that skin typology can change with time and many other factors, it is true that there is usually a tendency that is related to its composition and structure. In the case of skins with a tendency to dryness, they are characterised by an alteration in the normal fat content of their outermost layer, so that some of them, such as ceramides, have a reduced presence. This causes a greater propensity for this layer to flake off as the cementing substance that binds its cells together is not in an optimal state. In addition, this is a condition that tends to affect the whole of the body’s skin, including the hands, scalp, etc. As a result, people whose skin has this tendency often experience increased irritation, tightness and even flaking. Their skin often looks rougher, can take on duller tones and the appearance of the first wrinkles and fine lines is often accelerated. On the other hand, their tolerance to more aggressive cosmetic forms such as exfoliants or soaps, or to extreme temperatures, is worse than in skins with a higher oil content.
Dehydrated skin is in another position. In this case, they do not refer to a typology but to a skin condition which, if well treated, can be temporary. Dehydrated skin is skin with a lower water content. Once again, the skin’s barrier function is affected, as it is responsible for retaining water and thus maintaining hydration, but in this case it will be a transitory condition that will recover as soon as the skin’s natural hydration factor is restored. It is important to note that any skin, whether it has a dry tendency or an oily tendency, can at any given moment be deprived of the hydration it needs and therefore become dehydrated. These skins have an uncomfortable sensation on the face that they do not usually feel under normal conditions. Fine lines are also more noticeable, which disappear when normal hydration is restored. The pores of the skin also take on a more elongated shape when the skin is excessively dehydrated and also loses its radiance.
Therefore, although their “symptomatology” may be similar, the needs of a skin with a dry tendency and those of a skin that is dehydrated are not the same. The former will appreciate a regular routine that improves the skin’s barrier function, replenishing the lipids necessary to prevent water loss through the skin on a daily basis, while dehydrated skin will see great changes when it is hydrated at specific times, both at the skin level and from the inside, increasing the body’s water supply.
The difference between the two conditions again reflects the importance of knowing your skin well and personalising your skin care with products that adapt to the specific conditions it reflects at each moment of your life.
