How does sunscreen work?
The first thing we have to know is that, of all the radiation emitted by the sun, there are only two types of ultraviolet sun rays that can cause damage to our skin: we are talking about the famous UVB and UVA rays.
UVB rays are the reason for skin burns. UVA rays are what makes us tan, but they are also responsible for photoaging, are associated with the loss of elasticity and the appearance of wrinkles, and cause the appearance of spots and lesions on the skin. Both UV rays cause skin cancer.
Sun creams protect our skin in two ways: on the one hand, they act as reflective screens, and on the other, they absorb ultraviolet radiation, preventing them from passing to our skin.
One tip: use broad-spectrum sunscreen gel, which protects your skin from UVB and UVA rays. And don't limit yourself to just using sunscreen only in summer, use sunscreen all year round, even on cloudy days.
Now we are going to move on to the practical part, we are going to buy our sunscreen and the typical questions come to mind ... what type of sunscreen is better? What SPF do I choose?
What format of sunscreen is better?
Is it better to use cream, spray, or aerosol sunscreen? It is common to think that sunscreen gel is better than sun sprays or aerosols, but sun protection does not depend on the format.
As a practical matter, we can recommend:
- The sunscreens are perfect to apply on dry skin; this format is great for use on the face, neck, arms. To prevent it from coming into contact with the eyes and mucous membranes. But they cannot be applied on damp skin, because their formula is diluted, and they lose effectiveness.
- The sprays are very handy if you have to apply yourself, you cream the same because there are areas that we find it hard to reach, and spray allows us to apply the sunscreen without a problem. Remember to apply a generous amount, and help your hands to distribute the product well. Be careful with windy days, because we may think that we are pouring out enough products but there is a part that flies.
What SPF to choose?
The Sun Protection Factor or SPF (Solar Protection Factor) is important when choosing sun creams.
The SPF tells us this is the number of times by which the time we can stay in the sun without burning is multiplied. We see it with an example, if your skin lasts 10 minutes without sun protection until redness appears, by putting protection with SPF 30; you are multiplying those 10 minutes by 30.
But be careful, you have to take into account that sweat, baths, and the towel maybe removing the sun protection. That is why it is recommended to reapply sunscreen every time we take a bath or approximately every 2 hours, even if it has an SPF factor of 50 +.
It must be made clear that there are no sun creams with a total screen. No sunscreen protects us from 100% of the sun's rays.
A classification of sunscreens has been established for years:
- Medium sun protection: from SPF 15 to SPF 25 (they block 93% of the sun's rays)
- High sun protection: from SPF 30 to SPF 50 (they block 97% of the sun's rays)
- Very high sun protection: SPF 50 (they block 99% of the sun's rays)
From that level, the difference between a sunscreen with SPF 60 or SPF 90 is minimal; it is not much greater than an SPF 50. The dermatologist recommends that from Sunscreen Gel SPF 50, sun creams are only labeled with SPF 50, not let them rip you off and pay more for a sunscreen that's not worth it.
The biggest mistake we make when applying sunscreen is putting too little. For doing, it quickly, because we don't want to get stuck. In the end, we use half or a quarter of the amount we should put in.
Almost all sunscreens say "apply a generous amount" in their directions for use, but we hardly ever do.
Apply sunscreen without fear! It's better to prevent that.
Also, it is recommended to apply sunscreen 30 minutes before sun exposure. And don't forget areas like the ears, lips, and insteps. (Yes, we have also burned our insteps on occasion).
Now we have one of the common doubts. Are there waterproof sunscreens?
Is there waterproof sun protection?
Yes, there is indeed a waterproof sunscreen gel. But if so, why do you recommend reapplying sunscreen every time we bathe? Do not stay with the doubt; we will explain it to you.
That a sunscreen is waterproof means that while we are bathing that sunscreen continues to filter the solar radiation and protect our skin but at most the last 40 minutes. Therefore, once we go out, it is best to reapply it, because when we dry with the towel or touch each other, we can be removing the sunscreen.
