TOP Ingredients for Skin Nutrition and Hydration

The secret to healthy and radiant skin is proper nourishment and hydration. In the same way that you nourish your body with healthy food rich in antioxidants, you should also provide good nutrition for your skin. Hydration improves blood flow in your skin and helps protect it against negative external factors.

Hydrolifting is not necessary, and all you really need to do is to use products recommended by dermatologists that contain effective moisturizers that will also keep your skin beautifully nourished. And if you supplement this care with proper water intake, your skin is guaranteed to glow with a youthful beauty.



Also known as glycine, this plant amino acid binds with moisture, trapping it in the skin. It also activates your skin’s natural self-hydration mechanism, improves its texture and protects against mechanical damage. The anti-inflammatory and soothing effects of betaine also make it ideal for highly sensitive skin.

Betaine is available in La Roche-Posay Toleriane, a soothing makeup remover emulsion for skin with low tolerance.

Shea butter


Shea butter (or karité) is a vegetable fat loaded with essential vitamins with exceptional moisturizing effects. Queen Cleopatra was already aware of its effectiveness and allegedly used oils obtained from the sacred shea tree. The vitamin E found in shea butter protects the skin, while vitamin A regenerates and tightens it. The essential fatty acids of vitamin F help fight acne and promote skin restoration, while vitamin K promotes the elasticity of the epidermis and eases swelling.

Shea butter soothes your skin, retains moisture and provides elasticity and softness. Concerned about dry skin after a shower? Try La Roche-Posay Lipikar, a moisturizing and relipidating oil against irritation.


Niacinamide, a vitamin in the B group (specifically B3), increases collagen, fatty acid and ceramide levels in the epidermis, protecting the skin from harmful substances and free radicals. It also prevents water loss from the epidermis, reducing greasiness and providing efficient acne care. B3 is also effective against pigment stains; it is very gentle on the skin and has an anti-inflammatory effect. 


Carbamide, or uric acid, provides a hydrating and powerful softening effect. Synthetically produced urea is also a key ingredient in dermocosmetics as it accelerates the absorption of other active substances. Like glycine, it binds with water and restores the softness and elasticity of your skin. It has excellent disinfecting qualities and alleviates the effect of allergens on the skin, making it effective in the fight against atopy. To enjoy the benefits of urea, try Uriage Eau Thermale, a silky body lotion for dry and sensitive skin.



Seaweed purifies your body both internally and externally. It is utilized in dermocosmetics for its antioxidant, regenerating and anti-inflammatory effects and, like urea, can bind with other active substances and help with their absorption. Carrageenan is extracted from red algae and Irish moss and is used for efficient skin hydration. For a beneficial dose of antioxidants, try Aqualia Thermal intensive hydration serum.
