Stress, alcohol, tobacco, unhealthy diet negatively affect the skin.
A healthy diet is essential for the whole body, therefore the skin.
Eat plenty of fruits and vegetables, which supplies the facial skin with essential vitamins, minerals and antioxidants.
Choose low-fat or fat-free dairy products. Limit sweets.
Some research suggests that a diet high in processed or refined sugars or other carbohydrates and unhealthy fats promotes skin aging.
Unfortunately, some people do not pay much attention to the diet and forget that only a mask, moisturizer or lotion can not achieve the desired result.
Antioxidant-rich foods seem to have a protective effect for the skin.
Consider these skin-friendly foods:
- Carrots, apricots, and other yellow and orange fruits and vegetables
- Citrus
- Spinach and other green leafy vegetables
- Tomatoes
- Berries
- Fatty fish
- Nuts
- Beans, peas and lentils
