Fit by skin type
General, ingredient-based — not your personalized match.
See how this fits your skin
Take the skin test and I'll show you how suitable this product is for you.
Take the skin testThe Dr.Althea Aqua Marine Deep Serum is a concentrated, lightweight vegan serum designed to quench dehydrated skin while restoring its natural radiance. Formulated with 70% Bambusa Vulgaris (Bamboo) Water instead of purified water, it delivers a mineral-rich base that enhances the skin's ability to retain moisture. The serum features a patented 3D Hyaluronic Acid technology that targets multiple layers of the dermis for long-lasting hydration. Its distinctive natural blue hue comes from Guaiazulene, a chamomile-derived extract known for its powerful soothing properties. Combined with Vegan PDRN and Green Caviar Extract, this fast-absorbing formula strengthens the skin barrier and improves elasticity without leaving a greasy residue.
Aqua Marine Deep Serum is a watery-light serum from Dr.Althea. The formula is built mainly around hydration. The ingredient list runs to 34 ingredients, each broken down in full below.
By its ingredient list the formula reads as very light — essentially a water-and-humectant base with little emollient weight. With almost no emollient load it should absorb quickly and finish close to matte. Hydration is handled by Glycerin, Ethylhexylglycerin and Panthenol, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Glycerin, Ethylhexylglycerin, Panthenol and Propanediol.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Panthenol, Centella Asiatica Extract, Niacinamide and Sodium Hyaluronate.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Niacinamide and Panthenol.
On richness alone it suits Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on antioxidant protection, cell renewal and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.
It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.
Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
Based on the curated benefits documented for this product's ingredients.
Attracts and locks in moisture to keep skin plump and dewy
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Calms redness, irritation, and inflammation for sensitive skin
Regulates sebum production to reduce shine and greasiness
