Sunscreen cosmetics are necessary not only for usrest and not only in the south. If during the day you are not in the sun for more than 30 minutes - you do not need to use creams with light filters. But if the time spent in the sun is longer, or you are going to rest outside the city or in a park, in an open cafe, then regardless of the time of the year it is necessary to protect the skin from sun rays. It can be burned in April, May or September. To harm the skin enough even a small amount of harmful ultraviolet, the consequences are quite serious: premature aging, disruption of regeneration and even cancer. So it's better to be safe than to be insufficiently protected.
Principles of choosing sunscreen cosmetics
Sunscreen for face is chosen, likeall other cosmetics, based on the type of skin. For normal skin, no restrictions - choose according to your own preferences. For dry - the best option is a milk or cream with a dense texture and a lot of moisturizing ingredients. For oily or combination skin gel or fluid is more suitable.
There are two types of protective equipment: with a screening and blocking effect. It is better to buy sunscreen for the face with a blocking effect. A cream of this type contains titanium dioxide or zinc oxide, a fine powder that reflects the rays. This cosmetics, as a rule, is hypoallergenic and has high efficiency.
Screening creams contain chemicals,which often cause an allergic reaction. Therefore, before using them, it is necessary to test for the presence of allergies: spread a small patch of skin on the inner surface of the forearm with cream and hold your hand in the sun for 20 minutes. If there is an itch and reddening - to you the cosmetic agent does not approach.
When choosing a sunscreen for the face,special attention to the SPF (sunscreen) factor. The higher this index, the higher the degree of protection from ultraviolet radiation and the longer it can take in the sun without harming the skin. When determining the optimal protection factor, you need to take into account the color and tone of the skin - the lighter your skin, the more effective protection should be (more SPF value):
- For those who have very pale skin with freckles, light gray or light blue eyes, you need to choose a cream with a factor of at least 40-50.
- For those with skin light, but the eyes are darker, you can use cosmetics with SPF about 30.
- For owners of darker skin and medium-blond, chestnut hair, a sunscreen with a protection of up to 20 is suitable.
- For owners of swarthy skin and very dark hair, SPF10 will be optimal.
These indicators are relevant for those who rest on the Black Sea coast or the Sea of Azov. If you are farther north, the SPF value should be reduced by 10 units, if you increase it by 10 to the south.
After the skin tans, it will increasethe ability to independently block the effect of ultraviolet light, you can use sunscreen for a person with a lower SPF (lower by 10-15 units).
Remember that applying sunscreen cosmeticsyou need 25-30 minutes before exposure to the sun - it starts to act only after soaking. Do not rub intensely - this reduces the efficiency by 30%, just wait until the sunscreen is absorbed. Reviews of those who used cosmetics with protective filters, say that the frequency of appearance of pigment spots that appear when exposed to the sun decreases, the skin does not burn, does not flake and does not blush. With properly selected cream there is no drying and dehydration, tanning falls evenly and there is no feeling of tightness after sunbathing.</ p>
