About this sunscreen
Slouq 1% Hyaluronic Sunscreen Aqua Ultra Light Gel SPF 50 PA++++ is a chemical-and-mineral blend using titanium dioxide, zinc oxide, ethylhexyl methoxycinnamate, avobenzone and oxybenzone. The gel wears lightweight, but the mineral content pushes it high for white cast despite the ultra-light claim. It does not sting and is low for pore-clogging. With good protection and a score of 60.3/100, it is a hydrating everyday gel held back by its older filter mix and the inclusion of oxybenzone.

Does this Slouq hyaluronic gel sunscreen leave a white cast?
Yes, it rates high for white cast. The mineral content from titanium dioxide and zinc oxide can leave whiteness despite the ultra-light gel claim.
Is the Slouq 1% Hyaluronic Sunscreen Aqua Ultra Light Gel With SPF 50 Pa++++ good for oily or acne-prone skin?
The gel texture wears lightweight and is low for pore-clogging, and it does not sting, so it can suit oily skin. The main downside is the white cast.
Is it a mineral or chemical sunscreen?
It is a blend of both. It uses titanium dioxide and zinc oxide alongside chemical filters including ethylhexyl methoxycinnamate, avobenzone and oxybenzone.
