 Key Ingredients & Claims

Main / Featured Ingredients

• Hyalu-Cica Complex
   This is the signature blend that combines hyaluronic acid (multiple molecular weights) + Centella Asiatica (cica) to deliver both deep hydration and soothing / barrier support. The formula is often marketed as “90% Hyalu-Cica” (i.e. a high proportion of this synergistic complex
   - The product is described as containing 5 types / layers of hyaluronic acids to ensure hydration at different skin depths. 
   - Centella Asiatica Extract is a major component (many listings say ~92 %) as a soothing / skin-calming ingredient. 

• Birch Sap / Betula Platyphylla Japonica Juice, Ivy / Hedera Helix Extracts
   These botanical extracts are included for their hydrating, soothing, and support to skin elasticity / barrier. 

• Niacinamide
   Included for its brightening, barrier-strengthening, and multifunctional benefits (common in many hydrating / treatment formulas) 

• Other Botanical / Supporting Ingredients
   The formula also includes a range of botanical extracts (rose water, aloe, fruit extracts, etc.) and humectants / moisturizers like glycerin. 

Formulation Highlights / Marketing Claims

• Hydration & Moisture Locking: Because of multiple HA species + humectants, it aims to rehydrate dry / just-cleansed skin and reduce the “post-wash tightness.

• Soothing / Barrier Support: Through Centella and botanical extracts, it’s marketed to calm irritation, support weakened skin barrier, and reduce redness / discomfort. 

• Non-sticky, Light Finish: Many descriptions emphasize a gliding, non-tacky, fast-absorbing feel. 

• Gentle / Low Irritation: The product is claimed to have passed skin irritation testing and omit harsh additives (e.g. being fragrance-free, etc.) in many listings.

 Ingredient & Safety Notes

• On InciDecoder / analysis sites, the formula is noted to be alcohol-free, fragrance / essential-oil free (or at least mild) in many claims. 

• The ingredients list includes a significant portion of Centella Asiatica extract (~ 92 %) in many sources. 

• It also features various botanical extracts and fruit / plant derivatives, which may in rare cases be potential allergens for ultra-sensitive skins (though the product is positioned as gentle).

• Because of the hyaluronic acid content, in very low humidity environments, HA can sometimes pull moisture from the deeper layers—so appropriate layering with occlusives / moisturizers may help.

• As always, a patch test is advisable when introducing a new product, especially if your skin is reactive.

 How to Use / Application Tips

1. Right after cleansing, while skin is still slightly damp (or immediately after), apply 1-2 drops (or an appropriate amount) of this ampoule to face. 

2. Gently pat / press into skin to aid absorption. 

3. Follow up with your regular toner / serum / moisturizer / sunscreen.

4. Because this is “Step 0,” it’s intended to supplement (not replace) your regular hydration / treatment layers.

5. Use consistently to experience benefits across days/weeks; hydration and barrier support may show faster improvement than more gradual effects (e.g. brightness).
