Key Ingredients

  • Vitamin C: THD, a concentrated Vitamin C derivative that’s non-irritating, plus more stable and effective as an anti-inflammatory and brightener
  • Marshmallow Extract: Helping even sensitive skin achieve that healthy glow, this botanical aids active Vitamin C to relieve redness and inflammation while locking in skin-soothing moisture
  • Vitamin E: This additional antioxidant amplifies Vitamin C’s stability, potency, and ability to improve skin’s texture and firmness while protecting it from UV damage
  • Licorice Root: Rounding out the brightening botanical blend, antioxidant-rich licorice root helps even skin tone and treat hyperpigmentation, fading dark spots and preventing them from forming

Clinical Results

  • 87% saw smoother, visibly brighter skin
  • 87% agreed skin felt more hydrated and looked healthier
  • 82% experienced visible improvement in texture and more even skin tone

*Based on a third-party 8-week clinical study of subjects aged 18–55

How to Use

  • We recommend making Vitamin C a daily part of your AM routine and saving other actives (like Retinol Serum) for PM
  • To apply, twist the tip off one capsule and gently squeeze on fingertips to massage onto clean face and neck. Follow up with moisturizer and SPF to ooh, aah, and bask in your glow all day long
  • What to do with empty capsules: Empty capsules can be simply thrown out or melted down in a glass jar with boiling water. You can recycle all shipping materials, even the capsules' tube — traditionally, with the rest of your recyclables, or reuse it as a container in your home
