DEHYDRATION
Hydration: the key to a radiant, balanced skin
Skin dehydration is not the same as dry skin.
Dehydrated skin lacks water and can manifest itself through tightness, a dull complexion, lack of suppleness and the appearance of superficial fine lines.
Dry skin, on the other hand, suffers from a lack of lipids, especially when its protective hydrolipidic film is impaired - which also promotes water loss.
Well-hydrated skin is supple, soft, and resistant to external factors. It contributes to a radiant complexion and plays a vital role in preventing skin ageing and discomforts such as tightness and redness.
Factors influencing hydration
Skin hydration depends on internal and external factors:
Internal hydration
- Drinking enough water and consuming water-rich foods, such as fresh fruit and vegetables, helps to nourish the skin from within.
- Nutrition and nutrients: essential vitamins and minerals contribute to the elasticity and resistance of the skin.
External hydration
- Moisturising treatments: applying suitable products helps retain water in the superficial layers of the skin and strengthens its protective barrier.
Causes of dehydration
The skin, the body's largest organ, is exposed to multiple factors that can alter its hydration level:
Environmental factors
Climate: cold, heat and dry air weakens the hydrolipidic film and increases water loss.
Pollution and UV: external factors damage the skin barrier and accelerate ageing.
Lifestyle habits
Insufficient nutrition and hydration diminish the skin's ability to remain supple and radiant.
Inappropriate skincare:
Overly aggressive products or the absence of a moisturising routine weaken the skin.
Internal and genetic factors
Certain skin conditions (e.g. eczema, psoriasis, dermatitis) or genetic predispositions increase the risk of dehydration.
Ageing and hormonal fluctuations reduce the skin's ability to retain water.
Prevention and care
Keeping skin hydrated is essential for its health and radiance.
A few simple actions can help:
Internal hydration and nutrition:
- Drink enough water every day.
- Consume water-rich fruit and vegetables such as watermelon, cucumber or citrus fruits.
Daily care:
- Cleanse with gentle products to protect the hydrolipidic film.
- Apply a suitable moisturising treatment morning and evening (richer in the evening, lighter during the day).
- Use regular moisturising masks for intensive hydration.
- Gently exfoliate to remove dead skin cells and promote the penetration of skincare products.
Protection and the environment:
- Use a daily sunscreen to limit UV damage.
- Take short, lukewarm showers and avoid prolonged hot baths.
- Maintain optimal humidity levels using a humidifier in dry environments.
