Dr.Althea Aqua Marine Deep Serum (Blue) — Hydrating & Soothing Vegan Facial Serum

Dr.Althea Aqua Marine Deep Serum is a lightweight, vegan facial serum that delivers long-lasting deep hydration and soothing care for all skin types.

Designed in Korea and formulated without artificial colorants, fragrances, or parabens, this serum uses a patented hyaluronic acid system and Bambusa Vulgaris Water to replenish moisture more effectively than standard water-based serums. Its naturally derived blue tint and non-greasy texture make it easy to layer under moisturizers or makeup while panthenol and guaiazulene help strengthen the skin’s moisture barrier and calm irritation.

How does this serum lock in moisture throughout the day?

The formula combines a patented H-Active Booster hyaluronic acid technology with panthenol to attract and retain water in multiple skin layers, reducing trans-epidermal water loss. That multi-level hydration supports a smoother, plumper look that lasts longer than single-weight hyaluronic serums.

• Patented H-Active Booster enhances delivery of hyaluronic acid into skin layers.
• Panthenol (pro-vitamin B5) reinforces the moisture barrier to prevent drying out.
• Bambusa Vulgaris Water supplies natural humectant properties instead of purified water.

Will this soothe sensitive or easily irritated skin?

Yes, the serum contains guaiazulene, an ingredient known for its calming profile, and avoids common irritants like synthetic fragrances and colorants. The combination of soothing agents and barrier-supporting panthenol reduces redness and sensitivity triggered by environmental stressors.

• Guaiazulene provides cooling and comfort for redness-prone skin.
• Free from fragrance, parabens, and artificial dyes to minimize irritation risk.
• Light texture reduces the likelihood of pore clogging or heavy residue.

How should I use the Aqua Marine Deep Serum in my routine?

Apply after cleansing and toner, while skin is slightly damp to maximize absorption. Use a few drops and gently press into the face and neck, then follow with moisturizer and sunscreen in the morning or a richer night cream in the evening.

• Use 2–4 drops on damp skin for best penetration.
• Layer under moisturizer and SPF during daytime routines.
• Suitable for daily AM and PM use; safe to combine with most actives.

What makes this serum vegan and more natural than others?

The product is Vegan-certified and uses plant-derived ingredients for its blue color and hydrating base. Instead of purified water, it employs Bambusa Vulgaris Water for added plant-sourced moisture, and the brand avoids artificial coloring, synthetic fragrances, and parabens.

• Vegan certification ensures no animal-derived ingredients are used.
• Naturally derived blue tint from vegan-friendly sources; no artificial colorants.
• Formulated without perfume, parabens, or unnecessary additives.

Who is this for? Dr.Althea Aqua Marine Deep Serum suits anyone seeking deeper, longer-lasting hydration without heavy oils or fragrances — from dehydrated and combination skin to sensitive and mature skin types. It’s ideal for people who prefer clean, vegan formulations and want a lightweight step that strengthens the moisture barrier and calms stressed skin. If you need a daily hydrating booster that layers well under skincare and makeup while avoiding synthetic scents and dyes, this serum is designed to fit seamlessly into your regimen.
