Cosrx The Hyaluronic Acid 3 Serum

When skin feels dry, tight, rough, or lacking moisture, a hydrating serum can add an extra layer of comfort to your routine!

COSRX The Hyaluronic Acid 3 Serum contains 3% Hyaluronic Acid, along with an amino acid-rich Natural Moisturizing Factor (NMF) and ceramides to support hydration and the skin barrier.

Key Ingredients

• Hyaluronic Acid (3%): Attracts and holds moisture, leaving skin feeling hydrated and smoother.
• NMF Amino Acids: Supports the skin’s natural moisture balance and protects against dryness.
• Ceramide NP: Supports the skin barrier and reduces moisture loss.
• Betaine & Sodium PCA: Additional moisturizing ingredients that help keep the skin comfortable and hydrated.
• Tocopherol (Vitamin E): Provides antioxidant support within the formula.

What Is It Good For?

• Dryness: Helps replenish moisture when skin feels dry or tight.
• Dehydration: Adds hydration to skin that feels dull, rough, or lacking water.
• Rough Texture: Hydration can help skin feel softer and smoother.
• Sensitive Skin: The formula is designed around hydration and moisture-barrier support rather than strong exfoliating actives.
• Makeup Prep: COSRX recommends this product for dehydrated skin prone to makeup clumping. Its hydrating finish helps prepare your skin before applying the rest of your skincare routine.

Texture & Skin Feel

The serum has a lightweight, non-greasy texture that absorbs into the skin and leaves a hydrated finish. However, its feel can vary depending on how much you apply and your skin type.

You may find it slightly thicker or stickier, particularly in warmer weather.

How to Use COSRX The Hyaluronic Acid 3 Serum?

1. After cleansing, apply a few drops during the serum step and gently massage or pat into the skin.
2. Follow with moisturizer to help keep the moisture in. If your skin is very dry, you can layer a richer moisturizer for additional comfort.

You can use it in the morning and/or evening.
