Physical solar filter vs Chemical solar filter
There are two types of sunscreen: mineral and organic. We explain the difference below:
Mineral (physical) sunscreen is made with mineral ingredients such as zinc oxide or titanium dioxide. This type of sunscreen acts as a mirror that reflects or deflects the sun's rays. 
While organic (chemical) sunscreen contains synthetic ingredients such as avobenzone and octocrylene that, upon receiving UV radiation, absorb it, transform it into heat and return it to the environment.You may be wondering which of the two types of sunscreen is better, inorganic (mineral, known as a physical filter) or organic (chemical).
The answer is that they both work . In reality, what indicates the effectiveness of a sunscreen is the Sun Protection Factor (SPF). To be truly protected, it is recommended to use a sunscreen with an SPF of at least 30. Another point to consider when choosing a sunscreen is that it be broad spectrum, that is, that the label indicates that it protects both UVB and UVA rays.
Now, something that will help you decide between using a chemical filter or a physical one is your skin type, and the occasion or circumstances in which you will be exposed to the sun.
If your skin is sensitive , you could opt for a mineral (physical) sunscreen, as it does not contain chemical filters, making it ideal for this type of skin.
If you are going to swim or sweat , it is best to opt for an organic (chemical) sunscreen , since this type of sunscreen is absorbed into the skin, so it is more difficult for it to rub off with sweat or water.
In some formulations, physical sunscreens are combined with chemical ones. This combination is advantageous because there are usually synergistic effects between the different types of UV filters, so that the SPF effectiveness of the combination is better than that which could have been obtained using each type of filter separately.
All SunVeil sunscreens are clinically supported and endorsed by Advanced Science Laboratories (formerly AMA Laboratories) and feature broad-spectrum UVA and UVB protection.
