The reason this sunscreen has the following it does is texture. It is a fluid, not a cream — it spreads like water and vanishes.
No white cast, on any skin tone. Because it uses no mineral filters, there is nothing to scatter light and turn skin grey. For deep skin tones, chemical sunscreens like this one solve a problem mineral formulas cannot.
SPF 60 and fragrance-free. High protection without the ingredient most likely to irritate.
No oxybenzone, which is the chemical filter that draws the most concern. La Roche-Posay removed it from this formula.
It is also water-resistant for 80 minutes, which is unusual for something this light.
