A hydrating serum from Dr. Althea — the companion serum in the Aqua Marine line, designed to be layered before the Aqua Marine Watery Cream and Jelly Mist. The same signature blue guiazulene formula built on 70% bamboo water, with patented 3D Hyaluronic Acid technology that delivers hydration to multiple skin depths simultaneously. Contains vegan PDRN (Sodium DNA) — a plant-derived alternative to animal-sourced polydeoxyribonucleotide. Niacinamide, centella, four sea algae and the rare plant sugar raffinose complete the formula. Fragrance-free. Vegan. 30ml.

• 70% Bamboo Water + Patented 3D Hyaluronic Acid Technology — Bambusa Vulgaris water forms 70% of the formula base, bringing silica, amino acids and antioxidants into every drop; the patented 3D HA delivery system structures multiple forms of hyaluronic acid (sodium hyaluronate, sodium hyaluronate crosspolymer, hydrolyzed hyaluronic acid) in a three-dimensional matrix that allows them to hydrate the skin surface, mid-layers and deeper dermis simultaneously rather than acting only at the surface — this is the "deep" in Deep Serum
• Vegan PDRN — Sodium DNA — PDRN (polydeoxyribonucleotide) in most skincare products is sourced from salmon sperm; this formula uses Sodium DNA from a plant-derived source, delivering the same DNA-fragment benefits — supporting cellular regeneration, improving skin resilience and aiding repair — without any animal-derived ingredients; for vegan shoppers this is a significant differentiator in the PDRN serum category
• Raffinose + Fructooligosaccharides + Lactococcus Ferment Lysate — an unusual three-part biome and hydration complex; raffinose is a trisaccharide sugar found in beet, legumes and whole grains — a rare and exceptional humectant that outperforms many single-molecule humectants at moisture retention; fructooligosaccharides (prebiotic fibers) feed the skin's beneficial bacteria; Lactococcus ferment lysate delivers probiotic-derived compounds that calm inflammation and support barrier function
• Niacinamide + Centella Asiatica + Cyperus Rotundus + Adenosine — multitasking active complex; niacinamide brightens, controls sebum and supports barrier; centella calms inflammation and strengthens barrier; cyperus rotundus (nutsedge root) is an underrated sebum-balancing herb particularly effective for oily and combination skin; adenosine is Korean FDA-approved for wrinkle improvement
• 4 Sea Algae + Guiazulene + Sea Grapes + Agave — the Aqua Marine identity; Hizikia Fusiforme (hijiki seaweed), Sargassum Fulvellum, Laminaria Japonica and Caulerpa Lentillifera (sea grapes) provide marine mineral hydration; guiazulene (blue chamomile pigment) gives the serum its distinctive blue tint and provides anti-inflammatory calm; agave delivers additional humectant and soothing support

After toner, apply 2–3 drops to face and neck and press gently to absorb. Follow with the Aqua Marine Watery Cream for the complete hydration routine. Can be used AM and PM. 30ml.
