About this sunscreen

Koh Gen Do The Skinwake Hakko Essence Primer SPF 42 PA++++ is a mineral primer using zinc oxide as its single UV filter. It has a balanced finish, wears lightweight, leaves low white cast and is generally unlikely to sting. The low breakout trigger suits most skin, and the makeup-base fit is okay since it doubles as a primer. With a score of 49.0 and protection rated weak, it is better seen as a light primer with some sun support than a standalone sunscreen.

Is the Koh Gen Do Skinwake primer mineral or chemical?

It is a mineral product. Zinc oxide is its single UV filter, providing broad-spectrum protection.

Does the Koh Gen Do The Skinwake Hakko Essence Primer Smooth Color Control SPF 42 Pa++++ work under makeup?

Yes, it is built as a primer, so it is designed to go under makeup, and its makeup-base fit is rated okay. The breakout trigger is low and the finish is balanced and lightweight.

Is it a strong sunscreen on its own?

Its protection is rated weak and it scores 49.0 out of 100, so it is better treated as a light primer with some sun support than a standalone sunscreen.
