What it is

Dr. Althea Aqua Marine Deep Serum 30ml is a hydrating serum spread along skin texture. Consider stage and ingredients before the imagery of a blue bottle or formula. The same line’s cream and mist differ in size and application.

Bamboo water and hydration materials

Bambusa Vulgaris Water starts the list, followed by Water, Glycerin, Niacinamide, Raffinose and Panthenol. Hyaluronic forms, Guaiazulene, Lactococcus Ferment Lysate and Sodium DNA are also listed. Ingredient names cannot establish the manufacturer’s test conditions or uniform tolerability and results.

Choose serum and cream amounts separately

Spread an appropriate amount gently, then follow with the moisture finish needed. There is no requirement to buy a matching brand cream. The notice gives 12 months after opening; manufacturer is pack-marked and The Pure Lab is responsible seller. Prioritize actual pack expiry or concentration statements and do not apply excess in pursuit of acne treatment or procedure-like outcomes.

A buying question answered

The official 70% presentation refers to Bambusa Vulgaris Water, not PDRN at 70%. The notice separately lists Sodium DNA, Guaiazulene, Niacinamide, Panthenol and hyaluronic materials. Sodium DNA presence is not recast as regeneration treatment or injection-like effects. The line’s Waterly Cream and Jelly Mist have different formats and sizes; their formulas are not transferred. Check the actual 30ml serum pack and spread an appropriate amount along skin texture.

Use and comparison choices

Spread an appropriate amount gently along the skin texture. Let it absorb while assessing the amount needed, then follow with the next stage.

Torriden DIVE-IN is another hydrating serum candidate; shared humectants do not mean the same formula or feel.

Compare AESTURA AtoBarrier365 Cream 80ml when a richer moisture finish is needed after absorption. Adjust the amount by area; overlapping ingredient names do not make the formulas identical. Choose by application stage and the finish your skin needs.

Key ingredients

PanthenolEWG 1
A precursor to vitamin B5 that converts to pantothenic acid once absorbed. It works in two directions at once, holding water and helping settle the skin barrier, which is why it appears in both calming skincare and hair care. Its low irritation profile makes it a regular in sensitive-skin formulas.
NiacinamideEWG 1
A form of vitamin B3 that acts on the step where melanin transfers into skin cells, which is the basis for its use in tone-evening products. Research also covers barrier lipid production and oil control, giving it unusually broad application. In Korea it is a listed brightening functional ingredient, commonly at 2 to 5 percent.
Hyaluronic Acid
A glycosaminoglycan found in human skin and joints, notable for how much water it can draw in and hold. Cosmetics usually use the water-soluble sodium salt, though the acid form is sometimes listed directly. Molecular weight determines whether it sits on the surface or works down between corneocytes.
PDRN (Salmon DNA)
DNA extracted from salmon and cut to a defined length, widely known by the abbreviation PDRN. It was used in aesthetic procedures around skin renewal before entering cosmetics, where it holds water and conditions the skin.
