Once applied, sunscreen enriched with mineral filters helps protect skin from harmful UVA and UVB rays, reflecting them in several directions like a disco ball and preventing them from penetrating the skin. It’s called “mineral” (or “physical”) sunscreen because of the natural titanium dioxide it contains. This creamy product protects you from the sun as soon as it’s applied, so you don’t have to wait prior to sun exposure. Mineral sunscreen is also recommended for people with sensitive, sun-sensitive or scarring skin, or skin that has undergone an invasive aesthetic treatment.
Contrary to mineral sunscreen, chemical sunscreen contains synthetic molecules (such as Mexoryl and avobenzone) that, once absorbed into the skin, neutralize harmful solar rays and transform them into heat that the skin will then release. Invisible and water-resistant, chemical sunscreen, with its melting texture, is suitable for sensitive skin and physically active users.
At the end of the day, whether you choose a mineral or chemical sunscreen, know that both formulas are effective at protecting your skin from the risks of sun exposure. It is recommended that you apply it before going out in the sun, allowing the formula to dry and form a uniform film on the skin. Finally, remember that regardless of which type of solar filter you choose (mineral or chemical), it is always vital to opt for optimal UVA/UVB protection.
Beyond that, it’s a matter of preference; what matters is that you choose the best formula for you (SPF, texture, scented or unscented, etc.) and that you reapply every two hours in the sun, regardless of your lifestyle.
