Protecting the skin during summer is more than one recommendation: it is a necessity. However, there is a very common error that can undermine all the effectiveness of sunscreen, even when applied daily. Most people do not use the proper amount, especially on the face, one of the most exposed areas.
According to the Healthline website, the amount of sunscreen that should be applied to the face is often underestimated.
Using little product does not guarantee the protection announced on the label, which increases the risk of sunburn and other accumulated skin damage.
The publication states that the correct dose is equivalent to about a quarter of teaspoon. This measure can be difficult to apply on a daily basis, but there is a practical trick that makes it easier to use the index finger as a reference.
The trick of the finger to apply the right dose
According to the same source, the amount of sunscreen should fill the space from the first line of the phalanx to the tip of the finger.
This area corresponds approximately to the volume necessary to cover the face and neck effectively.
This method helps standardize the application and avoids neglected zones. Many people apply the product hurriedly or uneven, which may leave parts of the skin more exposed to ultraviolet radiation.
Why the right dose is important
Write the website that the Sun Protection Factor (FPS) only offers the promised level if the right amount of product is applied.
Otherwise, the skin will only be partially protected, even if the label indicates SPF 50 or higher.
In addition, uniform distribution is essential. Poorly made applications that leave discovered areas such as eye contour, ears or hair line further reduce the effectiveness of protection.

When applying (and reapplying) the protector
As the publication adds, sunscreen should be applied at least 15 minutes before sun exposure. This time is necessary for the chemical filters present in the formula to be absorbed by the skin.
The reapplication throughout the day is equally important. The recommendation is to do so every two hours, or immediately after swimming, sweating or drying your face with a towel. Even water resistant products lose effective in these conditions.
What if the day is cloudy?
According to the same site, many forget sunscreen on cloudy days. However, grape radiation, responsible for the aging of the skin, and UVB, associated with burns, remain present. The protection must be kept regardless of time.
Daily use of the protector is not just a summer measure. In the long run, it contributes to preventing premature aging, spots and skin diseases. Therefore, it is essential to incorporate this habit into all routines, even in colder stations.
Other tips for improving protection
For those who use makeup or other products on their face, the protector application should be done as a first step. Only then should the remaining cosmetics be applied.
The reapplication can be done with powder protectors or spray to facilitate routine.
It also refers to the use of wide flap hats and sunglasses complements protection.
These measurements are especially relevant between 11:00 and 16:00, when solar radiation is more intense.
