Is sun protection factor important and how to choose it?
Sun protection factor (SPF) is an important factor in protecting the skin from harmful sun damage. SPF protects the skin from ultraviolet (UV) rays, which can cause sunburn, skin damage, and increase the risk of skin cancer. Here's what you should know about the importance of SPF and how to choose the right type:
-
The importance of SPF : SPF protects the skin from harmful ultraviolet rays. The strength of protection is measured by SPF, which expresses how many times more sunscreen can protect the skin compared to without it. For example, if you have SPF 30, it means it can protect your skin for 30 times the time it takes to get a sunburn without sunscreen.
-
Choosing the right type : There are many types of sunscreens, such as creams, gels, and sprays. It is preferable to choose a sunscreen with an SPF of 30 or higher, which protects the skin well from harmful rays. It is also preferable to choose a sunscreen with biological or chemical sunscreens that effectively protect the skin.
-
How to use it correctly : Sunscreen should be applied generously to the skin about 15-30 minutes before exposure to the sun, and it is recommended to reapply it every two hours or after swimming or heavy sweating.
-
Taking care of sensitive skin : If your skin is sensitive, you may need to use a sunscreen that is free of perfumes and harsh chemicals that may cause skin irritation.
-
Avoid excessive exposure to the sun : In addition to using sunscreen, it is preferable to avoid excessive exposure to the sun during peak hours (from 10 am to 4 pm), and wear protective clothing, hats and sunglasses.
In short, SPF is very important to protect the skin from sun damage, and it is recommended to apply it daily and choose the appropriate type that suits your skin type and needs.
