Vitamin C Promotes Skin Cell Growth to Keep Skin Healthy and Prevent Aging
Skin care advertisements flood our screens and display panels with allegations that their ingredients hold the secret to tackle skin problems, especially aging skin. In the jungle of ingredient lists, hides substances such as collagen, hyaluronic acid, green tea extract and many others.
In addition to the safety and labeling requirementsThe beauty industry is largely self -regulated, which means that all demands are not supported by science. But vitamin C is different.
Continuous research confirms that this antioxidant reduces the effects of aging, making it a promising ingredient for ordinary skin care. Now, a research team in Japan has finally discovered how exactly vitamin C does – by promoting the growth of skin cells at the epigenetic level.
Aging skin and vitamin C
Our skin is a wonderful organ. Its many layers protect our body from external threats such as UV radiation, chemicals and microorganisms. But as we age, the skin deteriorates slowly, losing elasticity and protective force, which becomes visibly perceptible.
The most external layer of our skin is the epidermis, composed of five sub-layers. Most of the epidermis is made of keratinocytes, cells in a constant cycle of renewal and migration through the layers, dying at the top to build a strong protective barrier. With age, this recycling process slows down, leaving our skin thinner and ridic.
According to the study published in the Journal of Investigative Dermatology, VItamin is already widely recognized for its antioxidant properties, supporting the overall health of the skin. A long -term deficiency causes an epidermal withdrawal in mice and in humans. The previous data suggest that vitamin C regulates the growth and specialization of epidermal cells, but exactly how vague – so far.

How vitamin C induces the growth of skin cells
As explained in a press releaseThe researchers have used human epidermal models cultivated in the laboratory that closely resemble real skin to explore the role of vitamin C in skin regeneration. These models expose the top layer to air while nourishing it from below, as how our skin works in the body.
The team treated these models with vitamin C at concentrations typical of what reaches the skin via blood circulation. After seven days, the samples treated showed a thicker layer of live skin cells, and on day 14, this inner layer has become even more dense while the external layer of dead cells was slightly lit.
This indicates that vitamin C stimulates the growth and division of keratinocytes. Other tests have revealed more positive Ki-67 cells, a marker of active cell proliferation.
The study has also shown that vitamin C promotes DNA demethylation, a process that eliminates methyl groups blocking gene activity, allowing skin cells to multiply and mature effectively. DNA methylation is one of the main epigenetic processes, which encompasses all changes in gene expression that do not directly imply generations of genes.
Best for damaged and aging skin
Researchers have found that treatment for vitamin C has triggered more than 10,000 changes in DNA methylation, leading to a sharp increase in activity of 12 important genes which control cell growth. In simple terms, vitamin C retains genetic programs that help your skin renew itself and repair damage.
This means that vitamin C could be particularly beneficial for the elderly or anyone with slimming or damaged skin, which gives it the additional thrust it needs to rebuild and strengthen.
Of course, everyone’s skin is different, and what does wonders for one person may not have the same effect on another. But with results like these, it is clear that vitamin C is much more than a simple media threw; It is a way supported by science to help keep your skin healthy and strong.
