The sun gives us vitamin D and a good mood. But, alas, not everyone knows how dangerous ultraviolet rays can be for our skin if we get too carried away with sunbathing. Allergies, burns, irritations, age spots, dryness – it's still "flowers".
It's much worse when skin cancer occurs. Therefore, in order to prevent such a sad outcome, it is necessary to protect your dermis from the sun, not only in summer, but also in the cold season. For this purpose, experts recommend using a cream with spf. In this article, you will learn what this cosmetic product is and why you should use it regularly.
How does solar radiation affect our skin
To understand how the sun affects us, let's take a look at the main types of ultraviolet rays. There are 3 of them:
1. UVC Spectrum C – do not affect the dermis in any way, since the ozone ball does not allow them to reach the Earth.
2. UVB rays of spectrum B – pass through the surface of the Earth, then penetrate into the upper layers of the skin. Such rays contribute to the production of melanin – pigment responsible for skin and hair color. Also, ultraviolet B radiation is involved in the appearance of sunburn. But at the same time, it leads to burns and photoaging, and in some cases to oncology. Such radiation should be especially avoided during the period from March to October, and from 10 am to 4 pm.
3. UVA rays of spectrum A – thanks to them, a beautiful bronze tan appears on the body. But such beauty can be dangerous for the skin. After all, radiation penetrates not only into the upper, but also into the deep layers of the dermis, thereby destroying collagen and elastin fibers, and also causing such unpleasant phenomena as dryness, hyperpigmentation and photoaging. The appearance of a huge number of freckles is also associated with the action of ultraviolet rays of the spectrum A.
But the worst thing is that such ultraviolet radiation changes the structure of DNA cells and can cause skin cancer. UVA rays are active at any time of the day. You should not hide from the sun, as from fire. If you use ultraviolet radiation wisely, that is, contact with the sun only in the morning and after 16:00, then it will not bring any harm and even provide significant benefits to the body.
But if you abuse ultraviolet radiation, it will negatively affect not only the skin, but also the immune system.
About 80% of ultraviolet rays penetrate clouds and are reflected from surfaces such as water, asphalt, ice, snow, sand, grass. It is the reflected rays that act more intensely than the direct ones. For this reason, it is worth protecting the skin anytime, anywhere and in any weather.
An excellent protector against the negative effects of ultraviolet rays is a cream with spf.
Cream with spf: a cosmetic development that protects the skin from the sun
The cream with spf contains physical and chemical sunscreens. The main task of physical filters – the creation of a dense film on the surface of the skin that reflects the sun's rays. Such protection will come in handy for owners of sensitive and hypersensitive skin, as well as those who are allergic to the sun.
As for chemical filters, they are absorbed deep into the dermis, perfectly absorb and reflect ultraviolet. Working in tandem, physical and chemical filters provide a wide range of protection.
What is SPF and why is it needed
You must have noticed the inscription SPF on a jar of cream. This abbreviation stands for Sun Protection Factor and implies the designation of the sun protection factor. The number after it determines how well the product protects from the sun. Accordingly, the larger it is, the better the protection:
• SPF from 2 to 10 – protection at a basic level.
• SPF from 15 to 25 – medium level protection.
• SPF from 30 to 100 – high level protection.
SPF allows you to receive a certain amount of UV rays without further negative effects on the skin of the face.
The right choice of cream with spf – optimal protection for your skin
In order for a cream with spf to bring maximum benefit, it must be chosen correctly. Therefore, when going to a cosmetics store, pay attention to the following:
• Protection factor. First you need to decide on the degree of protection that you need. To do this, you should take into account the color type of your skin, the season and your location. So, in winter, a day cream with SPF 8 –20 will serve as the best option, and in summer – 15– 30. If you have fair skin, then choose a cream with SPF from 35 for the summer. And for those who live in a warm climate, where there are mountains or the sea nearby, you should pay attention to products with SPF from 30. Creams with protection factors of 50 and 50+ is only suitable for those who are prone to age spots, sun allergies and burns. Also, such a tool will come in handy after acid peeling.
• The presence of components that care for the skin. Panthenol, vitamin E, herbal oils and other components perfectly protect the dermis from premature aging and, in the meantime, saturate it with useful vitamins and minerals.
• Presence of allergens. Sunscreen creams typically contain organic ingredients such as zinc oxide and titanium dioxide. They serve as excellent reflectors of ultraviolet rays, but at the same time they are allergens. Therefore, if you are allergic to these components, it is better not to buy products with such components.
And one more important point: purchase products only from a trusted manufacturer, otherwise, you may stumble upon a fake that turns out to be a dummy. The best products are products made in Europe, the USA and Australia. The fact is that in these countries the level of SPF in cosmetic products is controlled quite strictly.
The nuances of using cosmetics with spf
Sunscreen should only be applied to clean skin. Therefore, you should perform a morning dermal care ritual, which includes cleansing and toning, and then apply the cosmetic product itself with SPF. After it, do not forget to finish your makeup with BB cream and mineral powder, preferably also with sunscreen.
Sunscreen must be applied 30 minutes before going outside. It is during this time that the active components of the product are put into operation and reliably protect the cover from ultraviolet radiation.
If you are going to relax on the sea or on the river, you can do without the last two means. But in this case it is desirable to use both creams: one – normal daily, and the second – sunscreen.
Cream with spf – it is a reliable protector of the skin, which, with regular use, will protect the dermis from age spots, premature aging and serious diseases. Therefore, do not neglect such protection, even if it is cloudy and cold outside.
We would also like to draw your attention to the fact that it is very important to consult with your specialist regarding the selection of home care products. Be sure to ask your doctor to prescribe the most suitable remedy for you, and this will help preserve the youth and beauty of your skin for a long time!
