The skin care ads flood our screens and advertising fences with statements that their ingredients maintain the secret to address skin problems, especially aging skin. In the jungle of the ingredients it lists substances such as collagen, hyaluronic acid, green tea extract and many more.
In addition to safety and labeling requirementsThe beauty industry is largely self -regulated, which means that not all statements are backed by science. But vitamin C is different.
Continuous research confirms that this antioxidant reduces the effects of aging, so it is a promising ingredient for regular skin care. Now, a Japan research team finally discovered how exactly vitamin C makes the trick, promoting the growth of skin cells at the epigenetic level.
Skin aging 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, loses elasticity and protective strength, which is visibly becoming remarkable.
The outermost layer of our skin is the epidermis, which consists of five sub -companies. 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 wrinkled.
According to him study Posted in Research Dermatology Magazine, VItamina C is already widely recognized for its antioxidant properties, which supports the general health of the skin. Long -term deficiency causes epidermal contraction in mice and humans. The above data suggested that vitamin C regulates the growth and specialization of epidermal cells, but exactly how it was not clear, until now.

How vitamin C induces the growth of skin cells
As explained in a Press releaseThe researchers used human epidermal models cultivated in the laboratory that are very similar to real skin to explore the role of vitamin C in skin regeneration. These models expose the upper air layer while feeding it from below, similar to the way our skin works in the body.
The team treated these models with vitamin C at typical concentrations of what reaches the skin through blood circulation. After seven days, the treated samples showed a thicker layer of live skin cells, and by the 14th, this inner layer became even denser, while the outer layer of dead cells was slightly thinned.
This indicates that vitamin C stimulates the growth and division of keratinocytes. Other tests revealed more positive cells for KI-67, a marker for the proliferation of active cells.
The study also showed that vitamin C promotes DNA dissectilation, a process that eliminates the methyl groups that blocks gene activity, allowing skin cells to multiply and mature efficiently. DNA methylation is one of the main epigenetic processes, which covers all changes in gene expression that do not imply alterations to genes directly.
The best for damaged and aged skin
The researchers found that vitamin C treatment triggered more than 10,000 changes in DNA methylation, which led to a great impulse in the activity of 12 important genes that control cell growth. In simple terms, vitamin C initiates genetic programs that help your skin give up itself and repair the damage.
This means that vitamin C could be especially beneficial for older adults or for any person with a thinning or damaged skin, giving it the additional thrust you need to rebuild and strengthen.
Of course, everyone’s skin is different, and what works great for a person It might not have the same effect on another. But with findings like these, it is clear that vitamin C is much more than just marketing exaggeration; It is a way backed by the science of helping to maintain your healthy and strong skin.
