Details

A lipid-based vitamin C serum formulated to help restore a brighter, more even-looking complexion while supporting daily antioxidant defense.

  • 30 ml dropper bottle in dark amber glass
  • 14% tetrahexyldecyl ascorbate, an oil-soluble vitamin C
  • Vitamin E, squalane and passionfruit (maracuja) seed oil
  • Anhydrous formula, free of water-based instability
  • Lightweight texture with a mild citrus scent

Who it's for: Adults noticing dullness, uneven tone or early signs of aging, and those with sensitive or dry skin who find water-based vitamin C too harsh.

Key benefits

  • Supports a brighter, more radiant look
  • Helps even the appearance of uneven tone
  • Provides antioxidant protection against daily stressors
  • Helps skin feel softer and more hydrated
  • Gentle option for sensitive-leaning skin
How to use
Apply 6 drops to clean skin each morning, gently pressing into the face, neck and décolletage. Follow with moisturizer and broad-spectrum sunscreen; avoid using it at the same time as strong retinoids or AHA/BHA acids.
Ingredients
Tetrahexyldecyl ascorbate (14%) is an oil-soluble form of vitamin C that may help neutralize free radicals and support the look of radiance. Vitamin E adds antioxidant support, while squalane and passionfruit seed oil help maintain moisture and skin suppleness.
