Careful sun protection is important to prevent skin cancer and premature aging. The sun protection factor you need depends, among other things, on your skin type, the skin's own protection time, the length of the sunbath and the intensity of the sun. Inform yourself here extensively on the topic of sun protection and learn with which tips and tricks you can safely prevent a sunburn.
Sunscreen and sunscreen
The selection of different sunscreen products is huge these days: sunscreen, sunscreen or even a gel or a spray? Keeping track of this is not always easy. In general, it is up to you which form of "sunscreen" you want to use. Each product has its own advantages and disadvantages:
- Gel: Contains little fat and is therefore suitable for people with acne as well as athletes.
- Milk: Maintains the skin especially well, especially if the antioxidant vitamin E is included.
- Spray: Spreads well on the skin, but it can cause cream loss during spraying.
- Cream: Offers a particularly effective protection due to its high fat content, through which the active substances can be better bound.
No matter which product you choose, make sure that the cream protects against UV-A and UV-B rays. Although this is the rule in Germany, a look at the packaging can not hurt. In general, the UV-A protection factor should be at least one third of the UV-B protection factor.
Correct cream is important
So that the sun cream can develop its full protection, you should definitely use enough cream. To protect the whole body, about 30 milliliters of sunscreen are needed - that is about three tablespoons. Distribute the cream evenly on the skin, otherwise the protective effect is reduced.
Small help: Divide the body into the following 13 games and use two finger lengths of sunscreen per game:
- Face and neck
- right arm
- left arm
- upper back
- lower back
- right thigh
- left thigh
- right lower leg
- left lower leg
- right foot
- left foot
Be sure to apply special care to so-called sun terraces such as the ears, nose or the top of the foot.
Self-protection time of the skin
Which sun protection factor you need to use depends largely on the self-protection time of the skin. This is between 10 and 30 minutes depending on the skin type. During this time, the skin is protected even without sunscreen from UV radiation.
The level of self-protection of the skin depends on the thickness of the corneal layer (hyperkeratosis) and the degree of tanning of the skin (pigmentation). By UV light, the self-protection of the skin can be increased slightly: Over time, namely, increase the thickness of the corneal layer and pigmentation. This will better filter the incoming UV rays and better protect the skin.
Sunscreen extends the self-protection time
By using a sunscreen, the self-protection time of the skin can be extended. The higher the sun protection factor, the longer the protective effect will last. Find out how long you can maximally stay in the sun by multiplying the skin's own protection time by the sun protection factor used. For safety reasons, you should only spend two-thirds of the calculated time in the sun.
The self-protection time can not be extended by Nachcremen.
The self-protection time can only be extended once. If the maximum time is reached, you should refrain from further sunbathing on the same day. After creaming neither the sun protection factor nor the self-protection time of the skin can be increased.
It makes sense, however, after all, because through water and sweat over time, part of the sunscreen and thus the protective effect is lost.
Sunscreen for the hair
Not only our skin, but also our hair suffer from too much UV radiation. Especially in conjunction with salt water or chlorine, it often happens that the hair becomes shaggy and brittle. To prevent this, special UV products are recommended for the hair. For example, there are sprays that contain a special UV filter. Often, they also contain nourishing ingredients that make hair supple again.
Protect allergic skin from the sun
If you have sensitive skin or are prone to allergies, you should choose your sunscreen carefully. It is best to use products without emulsifiers and preservatives.
First, carefully test the sunscreen on a small area of the skin. After that, wait at least 24 hours for your skin to show an allergic reaction. If you are unsure which remedy is right for you, it is best to consult a pharmacy.
Prevent skin aging and skin cancer
Careful sun protection is important to prevent premature aging and skin cancer. On the one hand, changes in the connective tissue can be caused by the UV radiation of the sun. This can lead to increased wrinkling over time.
On the other hand, the DNA of the skin cells can be changed by the UV radiation. Such damage to the genome can be partially repaired by the body's own repair mechanisms.
However, these mechanisms are not always successful. Especially with very large or repeated damage, it can therefore come to permanent changes in the genome of the skin cells. Such mutant cells can eventually lead to skin cancer.
