During the period when our skin is exposed to the sun's rays, we must take special care of those areas with pigmented lesions. In this case, photoprotection will be essential.
Protective formulations are designed to effectively protect the skin from both UVB and UVA rays. In addition, they must be photostable and cosmetically acceptable, and have minimal harm to human health and the environment.
The role of sunscreens is to prevent negative health effects caused by UVR. Scientific studies report that regular use of protective preparations reduces the risk of melanoma and squamous cell carcinoma of the skin, also inhibit the development of solar keratosis. Many studies have confirmed the effectiveness of photoprotection in delaying skin photoaging, both at the clinical and molecular levels. Protecting the skin from erythema formation through properly applied photoprotection is also extremely important due to the recognition of skin burn as a risk factor for melanoma development.
Great importance should be given to sun protection in the treatment of autoimmune diseases, as well as in organ transplant patients.
Which UV filter to choose?
They can be organic (chemical) or inorganic (physical, mineral) and can absorb or reflect UVR. Organic filters come in liquid or solid form and have the ability to absorb photons from UVB and UVA rays and convert the absorbed energy into heat.
A measure of the effectiveness of cosmetics that protect against UVB radiation is the standardized and international SPF factor. The higher the SPF index, the higher the standard of sun protection. The most important feature of a good photoprotective product is broad protection regarding UVB and UVA wavelengths. The photostability and water resistance of the preparations are also extremely important. Disorders in the structure of the filters occur, for example, under the influence of high temperatures (exposed directly to the sun, in closed cars). Therefore, we should warn against improper storage of creams containing UV filters.
Formulations should also be water-resistant and safe. Water resistance is determined by determining the SPF before and after a 20-minute water bath 2 times. For a formulation to earn the designation "water resistant," the SPF after the bath must reach at least 50% of the value before contact with water. To designate a formulation as highly water resistant, the same SPF value must be achieved after four 20-minute water baths. Due to the multiplicity of parameters that determine the effectiveness and safety of tanning cosmetics, it is very important to carefully check the composition of a given formulation.
Effective protection only with proven cosmetics
There are preparations on the market that may contain compounds that are unfavorable to the body, causing allergies, changes in hormonal balance and even carcinogenic effects. It is therefore recommended to choose cosmetics only from reputable companies, experienced in the production of specialized cosmetic preparations, such as Mesoestetic with SPF 50+ rating. In addition to protecting against the negative effects of sunlight, they moisturize the skin by retaining water inside, stimulate the process of protecting the epidermis, as well as act as antioxidants and stimulate anti-aging processes.
Protection of skin lesions from UVB radiation
Skin lesions such as pigment spots and scars need to be protected extremely effectively. A sunscreen stick with spot application and high SPF, such as Sun protective repairing stick SPF 100+, is helpful. Comprehensive skin protection will be achieved by using Melan SPF 130+ pigment control with an optimal combination of physical, biological and chemical filters, unifying skin tone and reducing imperfections.
