Why it will not pill
- Oxygen fresh finish: glow with a clean set
- Oil-soluble Vitamin C: THD sits comfortably in a silky base so it layers under SPF and makeup without rolling.
- Non sticky finish: Dries down clean so foundation grips smoothly.
- Mix-in ready: Add drops to Infinite Aura Moisturizer for a one-step glow.
Makeup-friendly by design
Kay’s Glow features THD Vitamin C in a fast-absorbing base with a gentle AHA trio to refine the look of texture. That combination helps makeup spread evenly while the serum supports a brighter, more even look. Use alone or mix into moisturizer. Let it set, then apply SPF and makeup.
The serum uses THD Vitamin C and Oxygen to create a fresh looking glow with a clean set. Let it dry down, then moisturize, SPF, and makeup.
