How to preventskin cancer?
1- If you want protection from ultraviolet rays, make sure that your sunscreen contains titanium dioxide and zinc oxide.
2- Some sunscreens stay longer than others, as UV light penetrates into anti-sun creams, causing them to lose their ability to protect the skin. Titanium dioxide and zinc oxide are sunscreens that don't break down when exposed to the sun's UV rays, so they'll stay put to protect your skin all day long.
3- Some types of sun protection creams suit certain skin more than others, and this is important if you sweat a lot or go swimming. In general, titanium dioxide and zinc oxide stay on the skin longer than most skin protection creams. Choose products that contain them, and choose a good type that is transparent to visible light, but works well in absorbing and reflecting ultraviolet rays.
4- Sunscreens are available in different forms: creams, gels, and sprays.
Creams are best for use on the skin smoothly. And some creams are based on water-resistant ingredients, so that the product stays on the skin for a longer period if you do water sports or sweat.
As for gels and sprays, some people prefer them, especially since they are easier to apply than creams to hairy areas.
When choosing protection creams for you and your family, it is important to consider its form on the body, because if a person does not accept its appearance on his body, he will not use it.
Thus, a light SPF 30 sunscreen that you are happy to wear daily will give you more effective protection than a high SPF product that is too greasy or too white, and therefore you won't use it regularly.
