Part 1 of the article of the same name contains information about the types of sunlight and what filters we need to protect against them. This information is very voluminous and relevant, so we continue to delve into the topic.

<h2>Physical VS Chemical filters</h2>

The type of substance contained in the sunscreen for the face during pigmentation directly affects the properties of the cosmetic product. This should be taken into account when selecting a product, so as not to create an uncomfortable feeling on the skin or provoke an allergic reaction.

There are two types of sun protection filters: physical and chemical. Tools can contain only one type of filter or be combined.

Mineral (inorganic/physical)&nbsp;&mdash; 

titanium dioxide (UVB), zinc oxide (UVA/UVB):

<ul>
	<li>reflect and/or absorb UV rays;</li>
	<li>are white, opaque, dense compounds, therefore they can affect the comfort of application and do not combine well with other cosmetic products;</li>
	<li>act immediately after application (except for filters with mineral nanoparticles, which).</li>
</ul>

A recent technology in physical filters is the use of nanoparticles. Their size allows them to pass through the skin barrier and act longer. Thus, these filters begin to act 25-30 minutes after application, having a more stable prolonged effect.
