How many hours should the sunscreen be renewed?
In general and based on a general rule, the duration of sunscreen cream renewal will be once every 2 hours. If you use this cream inside the house, the duration of the extension of the sunscreen cream is increased and reaches about 5-6 hours. In addition, if your activity is continuously outside the house or you sweat a lot, it is better to renew your sunscreen every 40 or 80 minutes. Also, keep in mind that high or low SPF has nothing to do with how long the sunscreen lasts, and in any case, it is necessary to renew it every 2 hours.
Why should we renew the sunscreen?
The ingredients of sunscreen that protect the facial skin against the harmful rays of the sun gradually lose their protective effect and become similar to when you did not use sunscreen. As a result, it is very important to observe the extension period of the sunscreen cream and its regular renewal.
How to use sunscreen with makeup
Definitely, using sunscreen after applying make-up will mess up your entire make-up and give it an unpleasant look. In this case, it is better to use SPF-containing powder or makeup fixing sprays and SPF-containing pancakes to use sunscreen and also to extend it.
How to renew sunscreen
In addition to the fact that the duration of sunscreen renewal is very important, the correct method of this renewal is also very important and should be taken into account. First of all, we must say that the most ideal condition for extending the sunscreen cream is to completely clean the skin and use it again. The reason is that during these two or three hours, the skin is exposed to all kinds of pollution and has absorbed them. As a result, reusing this type of cream can keep the contamination on the skin. However, in most cases, we are not in ideal and perfect conditions, and at the same time, renewing the sunscreen is absolutely necessary. If you have used mineral or physical sunscreen, there is no need to remove it and you can easily apply another amount of sunscreen on top of the previous cream. If you use chemical sunscreen, it is better to clean it with a micellar water and renew the cream. If it is not possible to use micellar water, there is no choice but to extend the sunscreen on the previous cream. Because renewing sunscreen even in these conditions is much better than not renewing it.
