This RNW Der. Concentrate Hyaluronic Acid Plus 30ml is a lightweight, translucent serum that contains 5 types of Hyaluronic Acid with a variety of molecular weight to target different layers of the skin, giving the skin an overall supple and plump complexion. Unlike other hyaluronic acid based serums, this RNW hyaluronic acid serum also includes γ-PGA (Polyglutamic Acid) a compound found in fermented soy that effectively increases the moisture of the skin and improves the skin's elasticity. Using a patented skincare technology known as Celrederm, this serum functions not only to protect the skin from external irritants, but also strengthens the skin starting right from the cellular level. 

This is the perfect serum to add to a skincare routine that is focused on locking in moisture and boosting hydration to dull looking skin, while reducing skin sensitivity.


Skin type:
Combination skin, Dry skin, Mature skin, Normal skin, Oily skin




  • Hyaluronic Acid: helps increase skin moisture and reduce appearance of fine lines and wrinkles
  • γPGA: a natural moisturizing agent sourced from Cheonggukjang (fast-fermented soybean) and natto helps retain moisture in your skin
  • Willow Bark Extract: is a natural astringent that provides gentle exfoliation and refine pores, helps soothe irritated skin



  1. After using a toner, apply 3 to 5 drops of serum to your skin
  2. Gently tap the fluid with your finger pads for better absorption


Quick tips:

If you live in a dry climate area, make sure to damp your face a little before applying this product. Applying Hyaluronic acid with less humidity can cause the opposite effect of drying out your skin.


For Dry skin, we recommend combining with RNW Der. Concentrate Ceramide Plus 30ml if you goal is to strengthen your skin barrier as a combination of hyaluronic acid and ceramide helps increase hydration and restore the integrity of a weak skin barrier.

For Mature skin, we recommend pairing with ARZTIN Regenerative Schild Cream 50g if your goal is to rejuvenate and regenerate your skin cells as a combination of hyaluronic acid and epidermal growth factor can hydrate and boost skin elasticity.
