Dry and dehydrated skin are skin types characterized by a moisture deficit, but they have different causes. Dry skin is a permanent condition – its sebaceous glands produce too little sebum, making the skin often thin, rough, and tight. Dehydrated skin, on the other hand, is a temporary condition where the skin loses more water than it can retain, and this can even happen with oily or combination skin.

Dehydration of the skin can be caused by external factors, such as cold and dry air, pollution, UV radiation, and improper skincare, like using harsh detergents or lacking hydration. It can also result from an inadequate diet, drinking too little water, stress, and lack of sleep, all of which weaken the skin’s natural protective barrier.

Features of Dry and Dehydrated Skin

  • Lack of moisture – dry skin has a permanent deficiency of lipids, leading to feelings of tightness and flakiness, while dehydrated skin results from a temporary water deficit.
  • Fine lines – due to insufficient hydration, the skin may show signs of aging more quickly, such as fine lines and expression wrinkles.
  • Rough texture – the skin feels rough to the touch, matte, and lacks elasticity. The absence of a natural lipid barrier makes it more sensitive to irritation.
  • Susceptibility to external factors – both dry and dehydrated skin react to changes in temperature, climate, heating, and improper skincare, which can worsen dryness and irritation.

Skincare for Dry and Dehydrated Skin

Skincare for dry and dehydrated skin focuses on intensive hydration and protection against moisture loss. Gentle cleansing products that do not disrupt the skin’s lipid barrier work best, while toners enriched with amino acids or postbiotics help with rehydration. For dry skin, creams with richer formulas containing lipids and ceramides are recommended, as they rebuild the natural protective barrier and prevent further dryness. Dehydrated skin responds well to rich moisturizing serums that replenish water loss, followed by a protective cream to lock in moisture. Regular use of moisturizing products, along with avoiding moisture-depleting factors such as hot water, dry air, and harsh cleansers, will help restore and maintain healthy, supple skin.
