Dr.Althea Aqua Marine Deep Serum — Blue Hydrating Vegan Facial Serum, Lightweight & Soothing

Dr.Althea Aqua Marine Deep Serum is a lightweight, vegan facial serum designed to deliver intensive, long-lasting hydration and soothing comfort to all skin types.

This serum centers on a patented hyaluronic acid delivery system and a bamboo-derived water base to deeply replenish moisture while calming stressed or sensitive skin. It avoids artificial colors, fragrances, and parabens, and uses naturally derived blue pigments for a visually distinctive formula. The texture feels airy and non-greasy, making it suitable for layering under creams or makeup as part of morning or evening routines.

How does this serum hydrate skin differently than regular serums?

Instead of using ordinary purified water, Dr.Althea replaces it with Bambusa Vulgaris Water to enhance moisture retention and deliver active ingredients more effectively. The H-Active Booster, a patented hyaluronic acid technology, helps carry hydration deeper into the skin for a plumper, smoother appearance without heaviness.

• Patented H-Active Booster improves hyaluronic acid delivery
• Bambusa Vulgaris Water as the primary aqueous ingredient
• Layerable lightweight texture for day and night use

Will this serum soothe and protect a weakened moisture barrier?

Yes — the formula includes panthenol to support the skin’s ability to hold moisture and reduce transepidermal water loss. Guaiazulene, an ingredient known for its calming properties, helps comfort irritated or reactive skin exposed to environmental stressors.

• Panthenol to help lock in hydration and strengthen the barrier
• Guaiazulene offers gentle soothing for redness or tightness
• Free from fragrances and parabens to minimize irritation risk

Is the color and texture safe for sensitive skin and daily use?

The serum’s blue tint comes from naturally derived vegan ingredients rather than synthetic dyes, reducing the chance of color-related irritation. Its non-greasy, fast-absorbing consistency makes it comfortable for daily layering beneath moisturizers or sunscreen without leaving residue.

• Natural blue pigment; no artificial colorants
• Lightweight, fast-absorbing finish for comfortable wear
• Vegan-certified and formulated without fragrance

How should I fit this serum into my skincare routine?

Apply the serum after cleansing and toning, while skin is slightly damp, to maximize hyaluronic acid’s water-binding benefits. Follow with a moisturizer to seal in hydration and sunscreen during daytime. It can be used every morning and evening as part of a standard regimen.

• Use on damp skin after cleansing and toning
• Layer a moisturizer or cream afterward to lock hydration
• Apply sunscreen during daytime when using in the morning

Who is this for: Dr.Althea Aqua Marine Deep Serum is formulated for anyone seeking stronger, longer-lasting hydration with calming benefits — ideal for dry, combination, and sensitive skin types, or for those who prefer vegan, low-irritant skincare. It works well for users who want a lightweight, everyday serum that boosts moisture and soothes external stress without synthetic fragrances or parabens.
