Recharge depleted moisture reserves and calm reactive skin with the advanced fluid engineering of the Dr. Althea Aqua Marine Deep Serum. Specially calibrated to treat chronic epidermal dehydration, moisture depletion, and environmental irritation, this active-dense nutrient serum blankets the skin barrier in lightweight, soothing comfort. By swapping standard cosmetic water for nutrient-dense botanical and marine extracts, it delivers lasting structural hydration deep into tired contours. This high-performance K-beauty formula balances uneven texture, reduces temporary redness, and fills out fine dehydration lines, keeping your complexion looking plump, exceptionally smooth, and uniformly radiant.

High-Performance Moisture Infusion & Cellular Rejuvenation

Patented 3D Hyaluronic Acid & Bamboo Matrix

At the core of this hydrating serum is an advanced fluid network built to correct severe volume depletion and dullness. By combining a high concentration of 70% Bamboo Water with a specialized 3D Hyaluronic Acid system, the formula easily passes through the skin's top layers. The bamboo-derived minerals prime the aquaporin channels, while the cross-linked hyaluronic acid grid forms a flexible, long-lasting moisture shield that continuously pumps hydration into the skin without evaporating.

Advanced Micro-Repair & Redness Reduction

Rather than offering simple, superficial hydration, this clean-chemistry formula pairs its hydrating sugars with an advanced blend of Vegan PDRN, Guaiazulene, and Probiotics. These active ingredients work together to calm thermal heat and lower surface stress. The soothing chamomile derivative reduces visible irritation, while the nucleotide elements and fermented lysates fix gaps in the skin lipid barrier, keeping the face highly resilient against outside environmental triggers.

Weightless Barrier Refinement

Housed in a precise dispensing bottle, the texture is engineered to absorb instantly into the skin. The non-sticky, fast-absorbing liquid format layers smoothly under heavy creams and sunscreens without causing pilling or adding excess grease. This makes it an ideal option for rebalancing oil-water levels across complex or combination skin types.

Skin Type All skin types, including severely dehydrated, combination-oily, dull, aging, and highly sensitive or reactive skin profiles.

Concerns Solved Chronic transdermal water loss, structural volume depletion, surface redness, rough skin texture, and moisture barrier damage.

Texture A lightweight, fast-absorbing, and non-greasy serum fluid with a natural pastel-blue tint derived from pure botanical extracts.

Usage Time Optimized for twice-daily application during both your morning (AM) or evening (PM) skincare routines.

Compatible Routines Fits seamlessly into any hydrating or skin-repairing lineup. Apply directly after your toner or essence step (such as the Aqua Marine Jelly Mist), and follow with a protective sealing moisturizer like the Dr. Althea 345 Relief Cream to lock in the active marine nutrients.
