The sun has an extremely strong effect on the skin, and is one of the main factors that accelerates the aging process of the skin. Proper use of sunscreen and moisturizing the skin makes it possible to maintain a young and healthy appearance for many years. However, there are people who are especially prone to photoaging — these are owners of fair skin, as well as those who, due to any circumstances, are forced to spend a large amount of time in the sun. For such patients it is recommended to use additional methods for the prevention of premature photoaging, read more about them on estet-portal.com in this article.
Main clinical manifestations of skin photoaging
The first signs of photoaging — this is the appearance of dryness of the skin and loss of its elasticity, which subsequently leads to the early appearance of wrinkles. Also, intense sun exposure can cause pigmentation disorders, affect the skin vessels, provoking the development of rosacea, and the occurrence of persistent erythema.
Under the influence of ultraviolet radiation, the processes of collagen degradation are activated, which leads to a weakening of the supporting frame of the skin.
Due to the fact that changes occur at the cellular level under the influence of the sun, the prevention of premature photoaging should include not only effective means of protection. It is also necessary to use preparations that will restore the structure of the skin from the inside, such as TwAc® polynucleotides, presented by Medhome Trading House.

Photoaging: the main mechanisms of the effects of the sun on the skin
When skin is exposed to sunlight, UV radiation is absorbed cells. As a result, free radicals are formed, which cause "oxidative damage" cellular structures: membranes, mitochondria and DNA. Histologically, photoaging may present with either hyperkeratosis or severe epidermal atrophy. Also, photoaging is associated with disorganization and destruction of collagen fibers, which is associated with the formation of chronic inflammatory changes at the dermis level.
Basic methods for preventing premature photoaging of the skin
To prevent photoaging of the skin, it is necessary to regularly use sunscreens with a high SPF level. However, if the patient is already showing signs of photoaging, the following may be recommended:
• retinoids that help hydrate the skin and reduce hyperpigmentation;
• antioxidants, such as coenzyme Q10, which are found in cosmetics, protect the skin from the effects of free radicals;
• fillers that provide skin hydration and wrinkle filling;
• polynucleotides that activate collagen synthesis, and also contribute to the restoration of the skin at the cellular level.
Active hydration and nourishment of the skin also helps to reduce the signs of photoaging.
Effective preparations for the prevention of premature photoaging of the skin
For effective prevention of photoaging, it is necessary to provide the skin with substances that are necessary for the synthesis of new collagen fibers. Most drugs provide active hydration of damaged skin, but do not affect the processes of cellular metabolism. TwAc® polynucleotides, presented by Medhome, contribute to DNA repair, activate fibroblasts, and also increase growth factor synthesis.
The combination of hyaluronic acid and polynucleotides in TwAc® preparations; makes it possible to combine the effects of revitalization and redermalization.
Thus, TwAc® optimally suited for the prevention of premature photoaging, as they provide both protection and restoration of skin cells.
