- 30% glycerin delivers intense hydration that really quenches parched skin
- Lightweight enough to layer seamlessly under makeup without pilling
- Non-comedogenic, working well even for acne-prone and sensitive skin
Watch out for
- Tacky, sticky texture is a dealbreaker for those sensitive to heavy-feeling serums
- Can make fine lines more visible, especially for mature or anti-aging skin concerns
- Some find it too lightweight for very dry climates or skin that needs richer occlusion
