Take care of your skin with sunscreen

Solar radiation is harmful and dangerous when it shines on the skin. Ultraviolet rays, especially type B, cause the synthesis of retalin D in the body, but will also cause damage. The symmetries in the eye become inflamed and can damage the retina, leading to cataracts and even blindness. Skin cancers such as Malignant melanoma, basal cell carcinomas, and horn cell carcinomas may result from prolonged exposure to sunlight. An increase in the number of rashes as well as infection may occur following sun exposure. Prolonged exposure to the sun causes premature wrinkles on the skin. Dark spots and decreased skin freshness are other long-term effects of sun exposure. Skin damage caused by UV rays or other sources can be prevented by using sunscreen.

Suitable sunscreen properties
Sunscreen should not be chemically exposed to sunlight and should inhibit both types of B and A UV rays. Do not cause allergies on the skin. It has no side effects on the body and is resistant to washing and sweating. Make the consumer feel good. Ultraviolet B waves with a wavelength (290-320) are more absorbed by cells of the epidermis (the surface layer of the skin) and damage the skin in the same layer. If UV waves have a longer wavelength (320-400) and penetrate deeper into the skin, in addition to superficial cells (epidermal keratinocytes), they also affect deeper cells (dermal fibroblasts). A-waves can also pass through glass, so protection against them, even indoors and in cars, is important.
The first sunscreens alone could block the penetration of B waves. Compounds are now on the market that also inhibit B and A waves infrared and have a much better quality.

Sunscreen
The amount of sunscreen is called SPF or Proteet Futo. The higher the SPF of a sunscreen, the more protection it provides against the sun’s ultraviolet rays. The appropriate SPF for each person depends on the type and amount of sun exposure. To estimate what sunscreen to use, you need to determine your skin type.
Sensitive Type 1: Always burn and never tan.
Sensitive type 2: Most of the time they burn and get a little tan.
Typical Type 3: Occasionally burns and gradually becomes tanned.
Typical Type 4: Burns lightly and is well tanned.
Insensitive Type 5: Rarely burns and is severely tanned.
Insensitive Type 6: They never burn, they are deeply irritating.
The use of sunscreen should begin at an early age.
On cloudy days, sunscreen should be used.
Sunscreen should be applied 20 minutes before sun exposure.
In addition to using sunscreen, other care, and wearing a hat, gloves are also required.
Physical sunscreens
Proper use of physical sunscreens prevents the skin from getting tanned in the sun and does not get sunburn. These compounds contain insoluble substances that spread on the skin, causing the sun’s rays to scatter or reflect before they reach the skin. The names of the materials used in this type of sunscreen are as follows: Zinc Oxide, Zirconium Oxide, Magnesium Oxide, Bika, Tact, Kaolin, Titanium Dioxide, Iron Oxide and…
Physical sunscreens can inhibit both WB and UVA rays if used in sufficient quantities and left on the skin long enough. Another advantage of these sunscreens is that because they do not react chemically with the skin, the risk of allergic reactions is lower and they are more suitable for sensitive skin, especially children. For some reason, physical sunscreens may not be as desirable. For example, due to the matte layer that they create on the skin, they prevent the skin from sweating and warm the skin. As a result, the skin becomes sweaty and on the other hand, their matte color may not be aesthetically pleasing. Also, these compounds do not wash off with water and may also loosen in the sun and reduce their protective effect.

Chemical sunscreens
Chemical sunscreens contain soluble substances and water or fat, and by absorbing the energy of some photons, they provide chemical protection against sunlight. These materials spread invisible layers on the surface of the skin. As a result, they are not seen. Therefore, they are more popular in appearance than physical sunscreens. Chemical sunscreens, based on the materials used to make them, may absorb B and A UVs. B-wave filters include benzylidine camphor and its derivatives, benzimidazoles, cinnamates, para-aminobenzoic acid, para-aminobenzoic acid and salicylic acid derivatives.

Filters A, B

Filters A and B include benzophenone derivatives and benzene benzene
Benzoyl, methane and terephthalene diene are renanone sulfuric acid. Sunscreens can have a sufficient protective effect to absorb both B and A rays, have no side effects on the skin and are resistant to sunlight.
