{"title":"Glycerin","description":"\u003cp\u003eGlycerin – an organic compound in the form of a colorless, odorless viscous liquid, the simplest representative of the trihydroxy alcohols. It is obtained by saponification of fats.\u003c\/p\u003e\n\u003cp\u003eBasic physical properties: high water solubility and hygroscopicity. It is precisely hygroscopicity that determines glycerin's moisturizing effect on the skin. Glycerin can draw moisture from the air and from the deeper layers of the skin. Therefore, it serves as a water reservoir for the skin. In addition, in the presence of humidity, nutrients from the cosmetic product penetrate more easily into the deeper layers of the epidermis. Thus, the benefits of glycerin for the skin are twofold: it hydrates and facilitates the penetration of ingredients from the care product.\u003c\/p\u003e\n\u003cp\u003eGlycerin also serves to protect the skin from aggressive external factors by forming a film on its surface. Therefore, it is often used in hand creams.\u003c\/p\u003e\n\u003cp\u003eApplied to curls, glycerin combats hair fragility and dehydration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits for the skin\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIt is one of the key factors for maintaining the optimal moisture level in the stratum corneum\u003c\/li\u003e\n\u003cli\u003eImproves skin firmness and overall appearance\u003c\/li\u003e\n\u003cli\u003eReduces fine lines\u003c\/li\u003e\n\u003cli\u003eForms a protective film on the skin's surface\u003c\/li\u003e\n\u003cli\u003eSpeeds up the wound healing process\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits for hair\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThickens thin hair, adding volume to the style\u003c\/li\u003e\n\u003cli\u003eAdds shine, elasticity, and manageability to hair\u003c\/li\u003e\n\u003cli\u003eReduces excessive static\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eContraindications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eGlycerin is contraindicated for external use in its pure form.
