Best sunblock or proper sunscreen cosmetics

On hot summer days many of us want to get the perfect tan, and others concerned about protecting skin from ultraviolet radiation, how to choose sunscreen cosmetics and how to find what is right for You? Let's try to understand what should be the composition of sunblock.

First of all I would like to draw attention to the sun protection factor or SPF (eng. - sun protection factor), it shows the degree of protection of the skin from sunburn, which has a particular tool. For example, your skin starts to turn red after 5 minutes of exposure to the sun, sunblock with an SPF of 15 increases this time about 15 times. Almost all creams and lotions for tanning SPF can be easily identified, as manufacturers indicate it on the label visible font.

Before you choose a suitable cream or spray, you need to determine what your skin. Generally, there are four main skin types: Nordic, Celtic, European and Mediterranean. Celtic skin type is the most sensitive to the effects of sunlight, but it needs the most protection from ultraviolet radiation. This type of skin have people with blond hair and blue eyes, often have freckles. Nordic skin type common in people with light blond hair, this type is also sensitive to the sun. The European type includes people with dark hair and grey, or brown eyes, their skin is darker, and therefore more protected from sunburn. And under the greatest protection from sunburn are people with a Mediterranean type, they have dark brown or black hair, dark skin from nature, she quickly tans and tan stays for a long time.

And now, let's define what affects the SPF. As part of any sunscreen cosmetics should include filters, protection from UV rays (UV filters). Namely, the number and types of these filters depends on the factor of protection from the harmful sun. UV filters are divided into two main categories: chemical and physical. In the product, they can occur together or separately. But it is better to choose those means, where there are both types of filters, as they have different properties and different protect the skin from exposure to sunlight. Chemical filters in sunscreen cosmetics are substances that penetrate into cells and selectively absorb ultraviolet rays of a specific spectrum (cinnamate, benzophenone, avobenzone and others). The most effective chemical filters are substances of synthetic origin, rather than the natural. Although many people prefer natural cosmetics.

Physical filters operate on the principle of reflection of rays. These include very small insoluble particles (titanium dioxide, zinc oxide). Unlike chemical, physical filters do not cause allergies, but they also have their downside is that they can stain the skin.

To improve the protective properties of the body in sunscreen cosmetics add antioxidants that work against oxidative processes. The most common antioxidant is vitamin E, also a good blocker "oxidation can be called L-carnosine.

The important role played by the Foundation, which will dissolve the filters and other components. The Foundation must not contain substances that are quickly oxidize or decompose upon contact with the sun, to such substances include non-concentrated oil. Today best serve basis silicones, as they are based on some criteria are superior to their organic counterparts.
