A daily brightening serum from Dr. Althea — Sea Buckthorn Water as the formula base (3.2x the Vitamin C of lemons), combined with a 20% Vita Boosting Complex of 9 vitamins and 45,000ppm brightening actives. Lightweight, non-sticky. EWG Green Grade. Vegan. Fragrance-free. 30ml.

  • Sea Buckthorn Water Base + 20% Vita Boosting Complex — Hippophae Rhamnoides (Sea Buckthorn) Water replaces plain water as the formula base, bringing naturally occurring Vitamin C, flavonoids, and carotenoids. The 20% Vita Complex layers 9 vitamin types including 3-O-Ethyl Ascorbic Acid (stable oil-soluble Vitamin C), Panthenol, and Niacinamide — delivering 45,000ppm of combined brightening actives to suppress melanin and improve skin tone.
  • Tranexamic Acid + Alpha-Arbutin — Additional Brightening — TXA blocks the UV-induced plasminogen pathway that triggers melanin production — a separate mechanism from Vitamin C. Alpha-Arbutin inhibits tyrosinase at a different point in the melanin pathway. Together with the Vitamin C complex, this serum targets dark spots through four distinct brightening pathways simultaneously.
  • 8 Types of Hyaluronic Acid — Non-Sticky Multi-Depth Hydration — Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Sodium Acetylated Hyaluronate, and five additional HA forms deliver moisture from the surface to deeper skin layers. The lightweight, watery texture layers cleanly under moisturizer and makeup without stickiness — a key note from reviewers.
  • Ceramide NP + Bifida Ferment Lysate + Beta-Glucan + Bisabolol — Ceramide NP reinforces the barrier. Bifida Ferment Lysate strengthens the microbiome. Beta-Glucan soothes and hydrates. Bisabolol calms any irritation from the actives. Together they make this serum suitable for sensitive skin despite the high Vitamin C content.
  • Ubiquinone + Hydroxydecyl Ubiquinone (CoQ10 Complex) + Tocopherol + Adenosine — two CoQ10 forms that penetrate at different depths for antioxidant protection and collagen support. Tocopherol (Vitamin E) adds antioxidant defense. Adenosine firms and reduces fine lines. EWG Green Grade ingredients throughout.

Apply 2–3 drops onto cleansed skin after toner. Pat gently to absorb. Follow with moisturizer and SPF in the morning. Vegan. Fragrance-free. EWG Green Grade. 30ml.
