The SKIN1004 Madagascar Centella Hyalu-Cica Water-Fit Sun Serum is a viral favorite because it behaves more like a high-end hydrating serum than a traditional sunscreen. As a non-nano chemical formula, it provides a completely transparent finish with zero white cast, making it an ideal daily shield that layers perfectly under makeup or stays invisible on bare skin.

The heart of this formula is the Hyalu-Cica complex—a specialized blend of Madagascar Centella Asiatica and Hyaluronic Acid. This combination treats sun protection as a soothing hydration step, specifically designed to calm redness and lock in moisture for sensitive or dehydrated skin.

Key Benefits

• Invisible "Zero-Cast" Finish: The chemical filters absorb seamlessly into all skin tones, leaving no chalky residue or "sunscreen smell."

• Advanced UV Defense: Offers professional-grade SPF 50+ PA++++ protection against both UVA (aging) and UVB (burning) rays.

• Intense Soothing & Healing: Infused with 9,800ppm of Centella Asiatica, which actively repairs the skin barrier and reduces irritation while you are outdoors.

• Environmental Support: A blend of seven sprout extracts (including Arugula and Green Tea) provides antioxidant protection against pollution and blue light.

Key Features

• Style: Lightweight, hydrating chemical sunscreen serum.

• Formula: Non-nano, non-comedogenic, and reef-safe.

• Finish: Dewy, "Water-Fit" glow with a non-sticky feel.

• Texture: Fast-absorbing, watery serum.

• Safety: Fragrance-free, hypoallergenic, and paraben-free.

How to Use

• Prep: Use this as the final step of your morning skincare routine. If you have oily or combination skin, this serum is hydrating enough to replace your morning moisturizer.

• The "Two-Finger" Rule: To ensure you are getting the full SPF 50+ protection, apply two full strips of product (the length of your index and middle fingers) to cover the face and neck.

• Timing: Apply 15–20 minutes before stepping out into the sun to allow the protective film to set.

• Reapply: For continuous protection during outdoor activities, reapply every 2 hours, especially after swimming or sweating.
