Benefits
  • High-strength antioxidant shields skin from environmental aggressors
  • Helps visibly reduce redness and reactivity over time
  • Supports a smoother, more even-toned complexion
  • Lightweight, water-free formula layers well under moisturizer
  • Budget-friendly way to boost a protective skincare routine
How to use
  • AM or PM, apply a small amount to clean, dry skin after watery serums.
  • Allow to absorb, then follow with moisturizer.
  • Use sunscreen in the morning.
  • Do not combine in the same routine with strong acids, pure vitamin C (L‑ascorbic acid), or copper peptides to maintain efficacy.
Ingredients
