Using sun protection is an important step to protect against harmful UV rays. Not only does it help protect against sunburns, it also reduces signs of aging and the risk of skin cancer. However, even if the sunscreen is included in the daily routine, experts say most people use too little product to achieve complete protection indicated on the label.
How much sun protection is needed to protect your face?
Although the exact dose of sunscreen is required for the size and shape of the face, dermatologists recommend the use of half to a quarter of a teaspoon. This allows for proper sunlight protection. If you want to make it easier to calculate the required amount, dermatologists have a simple method called the “finger method” that helps determine how much the protective product is applied to the face.
Finger method – how to correctly protect the face from the sun
According to Dr. Joyce Park, a dermatologist, will require 2-3 fingers in the product to properly cover the face and neck protection. This is necessary to keep protection completely effective. This method helps to ensure that you do not use too little product, as people often do not notice how much makeup you have to use to achieve the right level of protection.
It is also worth remembering that some places such as ears, lips and eyelids are often forgotten, but this area needs to be protected. This is especially important if you plan to be longer outdoors.
How often do you need to renew your sunscreen?
The efficacy of the sunscreen decreases with time, so it is recommended to apply a new layer every two hours or after bathing or severe sweating. This is especially important if you spend a long time in the sun.
