30 for 30 Sunscreen Challenge (15/30)

Today we're testing Kiehl's Better Screen Mineral UV Serum SPF 50+.

This mineral sunscreen uses zinc oxide and titanium dioxide in a lightweight fluid formula. It starts with a noticeable white cast, but after blending, it settles into a comfortable, creamy finish.

What stood out:
• Lightweight, fluid texture
• Creamy finish after dry down
• No pilling during reapplication
• Slight increase in white cast with a second layer
• Sunscreen film remained uniform after a few hours of wear

Our biggest takeaway:
A well-formulated mineral sunscreen with comfortable wear, though reapplication may make the white cast a bit more noticeable.

⭐ Final Score: 7/10
