• Ultra Hydration: Provides instant moisture replenishment to the skin and maintains hydration for up to 72 hours. With a combination of 12 hydrating ingredients, the serum eliminates dryness and tightness immediately upon application and gives the skin a “plumped” look.
  
• Restore elasticity and reduce wrinkles: a combination of medium molecular weight hyaluronic acid and a blend of natural moisturizers improve skin elasticity after just 4 weeks of use.
  
• An effective solution for skin during stress and seasonal changes: it is recommended to include it in care when the skin is particularly dehydrated: in winter (heating, frost), in summer (sun, air conditioners), during stress or lack of sleep (when the barrier is disrupted). The serum quickly restores moisture balance, removes peeling and discomfort, returning the skin to a feeling of softness and tenderness.

• Hyaluronic acid (Hydrolyzed Hyaluronic Acid / Sodium Hyaluronate) – intensely moisturizes, retaining moisture in the skin. Helps to plump, smooth and increase elasticity.
  
• NMF complex (Sodium PCA, Urea, Sodium Lactate) – basic molecules of the natural moisturizing factor, reduce moisture loss and increase elasticity.
  
• Blueberry extract (Vaccinium Angustifolium Fruit Extract) – rich in anthocyanins and vitamins, enhances antioxidant potential and gives a natural glow.
  
• BIYUSEN™ Thermal Water (Onsen-Sui) – mineralized water from a Hokkaido hot spring; stimulates cellular renewal and detoxifies.

Quench-Up is   IREN Shizen's intensive moisturizing serum for skin that can be oily, dull, and prone to peeling. It significantly increases moisture levels, restores the protective barrier, and returns a fresh, healthy look to the face after just one use. The formula combines:

• deep moisturizing agents to smooth fine wrinkles and maintain elasticity;
  
• antioxidant extracts to nourish, even out skin tone and strengthen natural defenses;
  
• natural moisturizers that "retain" water in the cells, preventing dryness and peeling.

The light, oil-free texture is instantly absorbed without leaving a greasy feeling, and is suitable even for problematic skin. Quench-Up is a quick help for hydrobalance and freshness of the face.

Use Quench-Up Hydrating Serum daily – morning and evening after cleansing and toning.

1. Apply 3-5 drops to face, including under-eye area and neck. Spread evenly, massage gently if desired.
   
2. Wait for complete absorption (~30 seconds), then apply cream. In the morning – with SPF.
   
3. For an additional effect in case of severe dehydration, you can apply 2 layers (after the first one is absorbed). Or mix 2 drops of serum with cream in the palm of your hand – this will save time.

• after a flight/dehydration – 2 layers of serum + mask;
  
• before an important event – intensive hydration 1–2 days before.
