These are the primal cells of the organism, that is, those present when it begins to form and the cells must be able to produce structures and tissues. Therefore, stem cells are those from which everything originates thanks to their ability to multiply quickly and self-reproduce, giving rise to copies of themselves or other specialized cells such as those of various organs and tissues. Another ability of stem cells is the restorative one, which is to replace dead or no longer functioning cells.
As the process progresses, stem cells, while retaining their ability to multiply and differentiate, lose some of their power giving rise to only that specific cell line. Therefore, in humans, stem cells represent the body’s repair system, even if with age, stress, bad habits, including food, their number decreases drastically, resulting in less self-repairing effectiveness by the body. Specifically, as regards the skin, these cells provide the molecules necessary to trigger the production of collagen and elastin and if the skin is damaged, even by sunlight or free radicals, the cell itself will repair itself and if this does not happen, it dies. And it is precisely at this moment that stem cells intervene, replacing the damaged cell with a new healthy one.
Stem cells are used in regenerative medicine and have been the subject of experimentation in the health field for many years. Research on plant stem cells is more recent, especially in the dermatological field, but it is no less lively than that on human cells, given the extremely positive results obtained from the experiments. In fact, it was discovered that the skin is very rich in stem cells at the level of the hair follicles that react positively to the application of Phyto stem preparations.
In general, stem cells are undifferentiated cells, that is, capable of originating cells from different tissues. They are found both in animals and in plants, but plant ones have a characteristic: even in adult specimens there are tissues composed of undifferentiated embryonic cells, capable of giving rise to the different plant tissues of the plant. This is why, unlike what happens in humans and adult animals, plant stem cells are totipotent regardless of age, i.e. capable of regenerating the entire plant, even if they are still strongly influenced by the conditions. environments in which they live.
Generally, plant stem cells are found at the root level or the level of the apical extremities and are referred to as meristems. In the dermatological field, on the other hand, human stem cells are partly located in the hair bulb and partly in the basal layer of the epidermis and have the function of preserving skin integrity, which allows the skin to be kept in a continuous state of renewal.
When we buy a moisturizing face cream based on plant stem cells it is important to know the methods of cultivation and extraction of this precious active ingredient. In fact, plant stem cells are grown in the laboratory in vitro, a method with rather high costs, but which, compared to other extraction techniques, guarantees the consumer numerous advantages. First of all, reproducing these cells in the laboratory allows you to control and test the growth parameters of crops, stimulating in some of them the accumulation of functional substances of specific interest in the cosmetic field. The plant extracts obtained in the laboratory are composed of a high concentration of specialized and reproducible molecules and have the advantage of being free of pesticides and pollutants potentially present in the extracts obtained from common plants grown in conditions other than those in the laboratory.
Biotechnologies also make it possible to avoid the exploitation of natural resources and make it possible not to alter plant biodiversity. In other words, stem cells are obtained respecting both the nature and the health of our skin, considerably lowering the presence of contaminants such as pesticides, herbicides, mycotoxins, heavy metals, or other pollutants. Furthermore, the in vitro processing of cell cultures in sterile environments with maximum biological safety allows to obtain a high titer up to 95% or to obtain the active principle at its maximum purity.
The removal of plant stem cells can take place from buds, fruits, leaves, or roots based on where the active ingredient is concentrated and what type of imperfection is to be countered. In general, the buds have the maximum concentration of stem cells, making it possible to obtain a cosmetic product of the highest level in terms of effectiveness. The life phase of the plant is also decisive. For example, in the germinative and evolutionary moments of the plant, the plant organism is at its maximum vital potential and therefore richer in stem cells.
The stem cells contained in cosmetic products act according to a dual function: protective and regenerative. On the one hand, they protect the skin and follicles from the damaging action of ultraviolet radiation as well as from all environmental and physiological stressors; on the other hand, they promote collagen synthesis and tissue regeneration thanks to the very high number of fibroblasts obtained through in vitro cultivation, creating a bio-revitalizing system that reproduces the activity of stem cells present in the skin. In general, cosmetics based on plant stem cells act against oxidative stress induced by free radicals, supporting the production of collagen and hyaluronic acid, counteracting wrinkles, spots, and sagging of the skin.
Cosmetic ingredients derived from stem cell cultures are divided into two categories:
. the first is obtained from the dispersion of whole plant stem cells in glycerol. It contains all the substances produced by stem cells, such as polysaccharides, phytosterols, and amino acids with a moisturizing, nourishing, and stimulating action;
. the second is obtained by homogenization and filtration of the cell mass, which allows the complete escape of useful molecules from the cells. The filtrate is concentrated to make the cosmetic functional substances even more active.
Stem cell cultures contain a complex of substances that includes mineral salts, sugars, proteins, phenols, amino acids, lipids and can protect the skin and therefore effectively contribute to the prevention of aging. In addition to the general cosmetic effect described above for plant stem cells, there are other specific ones, depending on the characteristics of the plant of origin and the cultivation methodology developed in the laboratory.
In the cosmetic field, there are many plants from which stem cells are obtained. These cell cultures have been selected in cosmetics for the resolution of some imperfections such as acne and damage from exposure to UV rays or based on their strong antioxidant capacity. On the other hand, against skin aging, excellent results were found on the capacity of stem cells extracted from a particular variety of Swiss apple trees (Malus Domestica) called Uttwiler Spätlauber.
It is an apple tree that has attracted the attention of scientists for the surprising longevity of its cells which are characterized by a high concentration of tannic acid, a chemical substance present in plant extracts capable of combining with animal skin proteins. Thanks to this particular property, the stem cells of this apple tree protect and maintain the functions of the stem cells of the skin, stimulating skin regeneration and protecting it from the daily threats represented by external environmental factors, which can accelerate the chronological aging processes of the tissues. Thanks to the metabolites that promote the longevity of skin cells, the plant stem cells of the Swiss apple tree Uttwiler Spätlauber are therefore the ideal element not only to delay the slow and progressive decay of tissues but also to stimulate cell development both during growth and in the repair of damaged tissues.
The use of plant stem cells in dermatology and cosmetology is certainly a particularly attractive sector of use with very significant commercial implications.
The possibility of remedying the phenomena of aging and skin damage through the simple use of plant stem products could certainly revolutionize the scientific landscape.
This is why Luxonskin has chosen Swiss apple plant stem cells as its main active ingredient (but there are 9 others!), A very expensive but highly effective ingredient!
In fact, as already said before, it is a very powerful antioxidant and repairer and prince of anti-aging products.
In just 30 days, customers noticed significant improvements in skin tone, hydration, and a noticeable reduction in wrinkles and blemishes on the face and neck.
