June 13 is European Skin Cancer Prevention Day, It is responsible for nearly half of all tumors detected worldwide. To do this, we must, among other things, properly protect ourselves from the sun, and one way to achieve this is It is the choice of sunscreen (right).
If you’re expecting to find the name “best” sunscreen here, read on, Because there is no single “best” sunscreen, but which one is best for you depending on many factors. Upon completion of the article, I hope you will be able to choose what you need.
What does SPF mean?
It is an abbreviation of sun protection factor It corresponds to the time when the skin is protected from sunburn. In other words, if your skin begins to redden within 15 minutes of unprotected sun exposure and you use an SPF 30 sunscreen, your skin will be protected from sunburn for 450 minutes. The higher the frame rate per second, the more radiation is filtered.
You need to know your skin type in the sun, and to this end, A scale of light patterns, from skin lightest to darkest, was created:
- First phototype: Red hair and very soft skin. They burn a lot even if they are slightly exposed. They tend to have allergic reactions.
- Second phototype: Fair and sensitive skin. Usually blondes with light eyes.
- Third phototype: Slightly darker skin, with brown hair.
- Fourth phototype: Dark-skinned people with black hair.
- Fifth type: The skin is slightly darker in color than the previous photogram.
- Sixth phototype: Black leather.
In addition, we will take into account the UV index, which can be referenced daily on Meteored. by region, Ranging from 1 to >11, from less to more radiation. The higher the radiation, the more protection is required.
What else should you look for in sunscreen?
Sun protection against UVB rays is essential as they are responsible for sunburn, But UVA rays cause skin aging and are also a risk factor for skin cancer. So it is recommended that sunscreen also protects against UV rays. For this, you can look for those surrounded by the letters UVA, which means that the protection will be at least a third of the SPF. If the cream has a UV protection factor of 30, it will have an UVA protection of 10.
is it enough ?
Everything we said above isn’t too little, but it’s not too much either. Sun protection using an SPF cream or gel is affected by many other factors such as your skin type and amount (Do not skimp, one teaspoon per area and don’t forget, under braces or feet) and timing of application, sweating, contact with water, friction from clothing or even age. Therefore it is necessary to renew the application every two hours. What about sprays? Sprays are great, but it’s hard to tell if you’ve applied the right amount of protection.
Physical or chemical filters?
Physical or metallic filters act like mirrors that reflect ultraviolet light. The problem is that it leaves the skin bright white. It is suitable for children and not because chemical filters are toxic, But because it is less likely to cause an allergic reaction.
Chemical filters (mineral, organic… all the same) work by absorbing solar radiation and re-emitting it in the form of heat radiation that is harmless to the skin. It is more cosmetic and spreads easily, although it is not suitable for people with dermatitis problems. It should be applied half an hour before exposure. Today there is also the possibility of mixed filters.
Can I use sunscreen last year?
On the labels we can see an open jar with a number followed by the letter M. This is the PAO or “period after opening”. Normally sunscreens have 12M, so no, they can’t be reused Because it will not be possible to guarantee what is stated on the packaging.
However, it is recommended to avoid exposure to the sun in the middle of the day. Babies under 6 months should not be exposed to sunlight (An umbrella or clothing with UV protection will suffice.) Do not forget to moisturize and remember: Tanning is a defensive action from the sun against aggression, and is used in moderation.
