What is it about?

Skin is considered dehydrated when the water content of the stratum corneum (most superficial layer) is less than 10%. In these cases, the skin loses its ability to retain water, thus increasing transepidermal water loss (from the deeper layers of the skin). As a consequence, the skin becomes opaque, rough to the touch, tense, tight, and fine expression lines may become more evident. It is important to know that there can be dehydrated skin even with the presence of blackheads or combination skin, and this can be observed because the skin in areas of expression tends to become marked or wrinkled more easily. It occurs in women and men of all ages and all skin tones. The causes may be an insufficient intake of water (you should drink approx. 2 liters a day), dietary imbalances, vitamin deficiency, alcohol and tobacco abuse, hygiene and skin care with inappropriate products, environmental conditions (cold, wind , sun, heating, air conditioning), contact with alkaline products, organic solvents or detergents, diseases that cause excessive water loss, intake of certain medications or stress.
