Photoaging is the premature aging of the skin caused by UV radiation from the sun. The fact of its manifestation is easily proved by a simple comparison of parts of the body that are constantly covered with clothing and open to the action of sunlight. The process is cumulative. Developing against the background of natural age-related changes, photoaging significantly exacerbates their manifestations. Of course, we are not able to stop the implementation of the genetic program of degradation of the skin.
But, as noted by estet-portal.com, there is an opportunity to significantly reduce the level of its photodamage. This can be helped by drugs and procedures in the system of controlled chemical skin renewal pHformula.
Causes of photoaging and its danger to the skin
The Sun supplies the Earth with a continuous stream of electromagnetic radiation. Photon energy, interacting with human skin, initiates a pool of molecular-chemical transformations. Small doses of UV provide vitamin D synthesis, calcium metabolism, improve psycho-emotional state.
However, excessive insolation inevitably leads to negative, destructive consequences for the skin.
The fact is that UV rays in the range of 290-400 nm disrupt the vital activity of cells, injuring the structural components of membranes and the intercellular matrix. Light quanta transfer molecules to an excited state. As a result, both completely stable new compounds and free radicals and reactive oxygen species are formed. Proteins and nucleic acids have absorption maxima in the UV region, so they are damaged first.
Then, as a result of free radical reactions, the lipids of the protective layer of the epidermis and cell membranes are destroyed. The process of lipid peroxidation becomes uncontrolled, leading to the formation of a huge number of reaction molecules. The latter secondarily damage proteins, DNA, RNA, leading to mutations. At the same time, destructive enzymes (MMPs) and inflammatory cytokines are activated. This enhances disorganization, the number of toxic molecules increases like an avalanche.
Of course, skin cells have a wide arsenal of means to maintain their homeostasis: these are antioxidants, vitamins, enzymes. However, the possibilities of the defensive and protective system are not unlimited, they are exhaustible, especially with age. Will it be possible to strengthen them – here much depends on a competent, conscious attitude to the problem, the individual responsibility of each person.
It is important to understand that the result of photoaging is a chronic inflammatory process leading to degenerative changes and malignant neoplasms. Skin cancer is a global problem today.
What are the clinical manifestations of the photoaging process
UV-B rays interact with the cells of the epidermis, causing erythema, burns, delayed sunburn, and awaken dormant tumors. UV-A rays form an immediate tan, damage the dermis, being the basis of photoaging and carcinogenesis.
Anatomically and histologically, photoaging is characterized by thickening of the epidermis. Atypical keratinocytes appear, pigmentation is disturbed. The number of Langerhans cells decreases. Long-lived molecules of collagen and elastin are destroyed: amorphous elastoid material appears, collagen fragments, forms uncharacteristic crosslinks.
Characteristic signs of photoaging:
• skin looks thickened and bumpy, with a yellowish tint;
• texture is clearly broken, wrinkles are deep;
• there are age spots, dilated capillaries;
• severe dryness, peeling, flabbiness, sagging skin.
How to prevent photoaging and restore damaged skin
How can a knowledgeable person act? Limit time spent in the open sun, especially at noon. Wear appropriate closed clothing in summer, use a hat if necessary. Protect the skin of the face and hands with cosmetic products containing sunscreen factors. To actively combat photoaging, it is recommended to use the pHformula controlled chemical skin renewal procedures, presented by Cosmetic Group.
In the summer, pHformula controlled chemical skin renewal procedures will help against photoaging ; these are protocols 365:
• instant renewal procedure with micro-resurfacing effect;
• Deep cleansing facial with a refreshing effect;
• Instant skin radiance treatment;
• renewal procedures in the delicate areas of the eyelids and around the lips;
• renewal of the skin of the neck and decollete;
• rejuvenating AGE 365 renewal procedure;
• clearing procedure for updating MELA level 1.
All of the above protocols allow you to restore the skin even in conditions of active sun. The fact is that the creators of pH formula preparations have a clinic in Cape Town. Many years of experience with patients in South Africa allows us to observe the effectiveness and safety of formulas on various skin phototypes at a high level of insolation.
The composition of the preparations speaks for itself:
• organic acids - mandelic, lactic, lactobionic, salicylic, phytic, pyruvic, as well as ferulic and glyceritic;
• antioxidants;
• vitamins - B3, C (ascorbic acid, magnesium ascorbyl phosphate), A (retinol), E (tocopherol),
• glutathione,
• gluconolactone;
• metabolizers - perfluorodecalin, saponins;
• amino acids - alanine, serine, proline.
In addition, the preparations contain activators of collagen synthesis, substances that improve intercellular communication - in the form of patented complexes.
New home care products to prevent photoaging
The pHformula system perfectly complements professional treatments with home care preparations. Experts recommend a set of products for use depending on the age of the patient, the constitutional features of the skin and the level of photoaging.
Among the new products is a pharmaceutical and cosmetic product for the protection, rejuvenation and beauty of facial skin: compact powder, compact foundation.
The product has a high level of skin protection against UVB and UVA radiation - spf50. It has a creamy texture and is applied with a special applicator, forming the thinnest silk layer. The superb uniformity of distribution results in an amazingly smooth, beautiful finish with a light tan effect.
The texture of the powder adapts to the skin color and perfectly hides pigmentation disorders. When applied again, it enhances the intensity of the color. The product does not create occlusion, non-comedogenic.
Safflower oil in the composition of the powder provides long-term softening of the skin, improves blood circulation, and eliminates inflammation. Tocopherol and squalene support the protective potential of the skin, providing an antioxidant, regenerating effect. Beta-sitosterol enhances the action of all components and perfectly rejuvenates.
Properly selected salon treatments, supplemented with pHformula home care products from the official distributor of Cosmetic Group, help prevent the negative effects of UV rays on skin cells and avoid photoaging, and if not him to defend himself – help cells quickly restore their functions.
