Hada Labo Gokujyun Premium Serum – Hyaluronic Acid Essence

The Hada Labo Gokujyun Premium Serum is the most concentrated step in the Gokujyun Premium lineup – a lightweight yet intensely hydrating essence packed with 7 distinct types of hyaluronic acid. Each form targets a different layer of the skin, building moisture from the surface down to the deeper layers of the stratum corneum.

7 Types of Hyaluronic Acid

• Sodium Hyaluronate — classic surface hydration
• Nano Hyaluronic Acid (Hydrolysed HA) — ultra-fine particles penetrate deep into skin
• Super Hyaluronic Acid (Acetyl Sodium Hyaluronate) — retains twice the moisture of standard HA
• Skin-Adsorbing HA (Hydroxypropyltrimonium Hyaluronate) — bonds to skin for a protective moisture film
• 3D Hyaluronic Acid (Sodium HA Crosspolymer) — forms a 3D moisture network within skin
• Fermented Hyaluronic Acid (Lactococcus/HA Ferment Filtrate) — enhances absorption and skin receptivity
• Penetrating HA (Hydrolysed Sodium Hyaluronate) — reaches deep into the stratum corneum

Also contains Aphanothece Sacrum polysaccharides (Sacran) – a rare freshwater algae extract with exceptional moisture-binding capacity.

How to use: After cleansing, pour an appropriate amount into your palm and gently press into skin until fully absorbed.
