About this sunscreen
Obagi 360 Hydrafactor SPF 30 is a chemical sunscreen moisturiser built on older-generation filters including ethylhexyl methoxycinnamate, ethylhexyl salicylate, benzophenone-3 and avobenzone. It wears with a dewy finish, stays lightweight, and shows little to no white cast, which works well on drier skin. Pore-clogging risk is generally low, though it can sting a moderate amount around the eyes. Protection lands as moderate, giving it a middling overall score.

Does Obagi 360 Hydrafactor SPF 30 leave a white cast?
No, white cast is low. It uses chemical filters, which generally absorb without leaving a white tone, and its dewy finish suits drier skin.
Is the Obagi 360 Hydrafactor SPF 30 mineral or chemical?
It is a chemical sunscreen. The filters include ethylhexyl methoxycinnamate, ethylhexyl salicylate, benzophenone-3 and avobenzone, all older-generation chemical filters.
Is it good for acne-prone skin?
Pore-clogging risk is generally low, which is favorable for acne-prone skin. Note the finish is dewy rather than matte, so very oily skin may prefer a matte option.
