Plant glycerin 100ML PURITY 99.7%, new
Plant glycerin (or glycerol) is a colorless, odorless liquid but also transparent, hygroscopic and non-toxic, it is safe for the environment. Vegetable glycerin is made from vegetable fats, without any animal products. The best one should not contain admixtures, we are already talking about pure at 99.5%.
Skin – structure and functions
Do you know that the skin is our largest organ, providing comprehensive protection: mechanical and thermal, against fluid loss, against radiation and infections.
It consists of the following layers: subcutaneous tissue, dermis and epidermis.
The stratum corneum is the outermost. It is constituted by corneocytes, cells resulting from the final actinic keratosis, they are filled with keratin. Corneocyte enzymes actively participate in skin biochemical processes. The natural moisturizing factor contained in them ensures water binding in this layer, and these cells form the shape of a brick wall. They are bound by a binder consisting of polyunsaturated fatty acids, cholesterol and ceramides (generally lipids). It is this layer that actively participates in the phenomenon of skin moisturizing and is a barrier to transepidermal water loss (TEWL). Due to the fact that the stratum corneum is most visible, its aesthetic role is obvious. [1,2,6]
Humectants – skin moisturizers
These ingredients are highly hygroscopic, i.e. they have the ability to absorb and retain water. Their task is to increase the water content in the stratum corneum. This makes it moisturized, tense and also increases its elasticity, and wrinkles are less visible. In the case of skin prone to oily, they are recommended as safe agents because they do not have a comedogenic effect, which means that they do not cause blackheads that this type of skin is prone to. For dry skin, they should be combined with emollients, agents with a more greasing effect – e.g. cosmetic oils. We include, first of all, one of the best – glycerin. [2,3,8]
Vegetable and pharmaceutical glycerin
It is designed to protect the skin from irritation and accelerates the regeneration of already damaged. [2,8] It has been found that glycerol occurs naturally in the stratum corneum as a humectant.  Topically applied, it can be actively absorbed by skin cells. Accumulates in the stratum corneum, maintains normal lipid structure between cells. It gives a keratolytic effect (affects the peeling of corneocytes, which is necessary in maintaining the proper condition of the skin. This improves the appearance of a dry and scaly layer, scales). [4,6]
Glycerol – concentrations.
In an interesting study, after acute chemical skin irritation, glycerol from 1% to 10% was used. The results of the study suggest that glycerol replaces the natural moisturizing factor. In this way, it improves skin hydration and promotes the process of physiological repair of the skin barrier, i.e. accelerates healing.  These effects persist for up to 7 days after stopping glycerol treatment.  This proves the protective and regenerative role of glycerin. [2,3,4,7]
High levels of glycerol (25-40%) cause corneocytes and their binder to “swell”, which is considered a factor that increases skin barrier resistance. It also has antimicrobial properties and prevents superinfection. It is recommended to avoid higher concentrations because they lead to secondary drying. [2,4,5,7]
Vegetable glycerin – who is it beneficial for?
Glycerin will work on people with skin:
– normal or oily to additionally moisturize it and extend its youthful appearance (in concentration up to 20% )
– problems with dry, flaky skin – for example, in atopic dermatitis (glycerin even in a concentration of 20% is better tolerated than urea, and 10% is sufficient), in psoriasis or in the case of dryness caused by low humidity (cold and windy, heating season) – to improve the skin’s protective barrier. In addition, glycerol increases the penetration of dermatological drugs. [2,4,5,7,13]
– exposed to frequent contact with detergents (necessity of frequent hand washing as well as washing dishes and cleaning) [5,8,9]
– prone to the formation of difficult-healing wounds – as a prophylaxis in people with diabetes and atherosclerosis of the lower extremities or varicose veins (in these cases there is a greater possibility of the formation of difficult-healing wounds, e.g. on the lower legs or feet) [7,11]
Plant glycerin – how to use it?
Glycerin works as a moisturizing and nourishing agent for the skin at a concentration of 3%, but the effect is concentration dependent, 10% is more effective than 5%.  For a cosmetic to be effective, it should also contain water. According to research, it is great as a bath additive (250 ml per bathtub of water).  Glycerol is ideally suited as an additive to Ol’Vita hydrolates (5-15 ml per 95-85 ml hydrolate). With the selected Ol’Vita cosmetic oil, you can create a moisturizing and nourishing lotion (90-70 ml of hydrolate is combined with 5-15 ml of plant glycerin, then we add 5-15 ml of Ol’Vita cosmetic oil and shake well; use for washing and cleansing the face or nourishing and moisturizing the rest of the body). Glycerin is also a great addition to the masks. For example, based on Ol’Vita clay or raspberry seed peels / masks or evening primrose Ol’Vita (together with water or hydrolate and cosmetic oil). The addition of glycerin (a few drops) will strengthen the moisturizing effect of the cream used every day.
