Face cream with urea: benefits and harms
The skin of the face is quite sensitive to external influences. Long stay in the cold provokes dryness and peeling of the epidermis. Heat, on the contrary, contributes to the expansion of pores and the appearance of acne. Keeping the skin in a healthy state will help regular cosmetic procedures. Urea creams are an effective and popular care product. They moisturize the epidermis well and are indicated for use by persons with increased dryness of the skin.
The benefits of urea in cosmetics
Urea or, scientifically, carbamide is a chemical compound, diamide of carbonic acid. It is white crystals, highly soluble in water, which cannot be identified by smell. Nearly two centuries ago, the chemical compound was first discovered in urine, which led to its name.
Carbamide is present in the epidermis and provides proper hydration to the skin of the face and body. However, its deficiency in the body leads to dryness and flaking of the skin. It is proposed to fill the deficiency of the substance with the help of creams, which include carbonic acid diamide.
You can recognize the remedy by the presence of a label on the ointment with the abbreviation Urea.
Due to its microscopic size, carbamide easily penetrates through the pores into the epidermis and retains moisture there. This contributes to proper hydration of the skin for a long time. Only cosmetic products with hyaluronate will compete with ointments with diamide of carbonic acid. However, the latter substance breaks down faster and has a weaker effect.
Useful properties of urea in the composition of creams:
- Well moisturizes the skin of the face, hands, feet, body due to the ability of urea to retain moisture inside the epidermis;
- Provides strong protection against drying of the skin, creating a protective invisible film;
- Promotes the regeneration of damaged cells, stimulates the growth of new ones;
- Relieves itching, pain and burning in the treatment of eczema and psoriasis;
- Carries out deep cleansing of the skin from dead particles, fat and dirt;
- Normalizes the pH balance, which helps to soften the epidermis;
- Increases skin resistance to external negative factors – ultraviolet, cold, wind;
- Smoothes wrinkles, evens out the tone of the epidermis, improves firmness and elasticity.
Urea also improves the absorption of other components of cosmetics and prolongs the life of ointments.
For the manufacture of creams with urea for the face, urine is used that is not obtained naturally, but synthetically.
