COSRX The Ceramide Skin Barrier Moisturizer 80ml

The gold standard in barrier-focused hydration with ceramides

A ceramide-based moisturizer designed to care for compromised skin barriers. The skin-compatible trio of ceramides, cholesterol, and fatty acids works to protect weakened barriers, while five types of hyaluronic acid and panthenol (vitamin B5) deliver deep hydration from within. The formula glides on smoothly and sets to a non-sticky, hydrated finish that layers beautifully under makeup without pilling.

Clinically proven hydration and soothing power

After just one application, moisture was shown to reach 12 layers deep into the stratum corneum, with hydration maintained for up to 200 hours. When applied to heat-stressed, reddened skin, a 60.8% soothing effect was observed within 10 seconds. After four weeks of use, dryness-related itchiness improved by 63.3%.

• Immediate improvement in surface and deep hydration levels
• Reduction in transepidermal water loss
• 61.9% improvement in temporary redness (after single use)

Gentle formulation for sensitive skin

Dermatologist-tested. Suitable for sensitive skin. Completed hypoallergenic testing and non-comedogenic testing (won't clog pores). Formulated without fragrance or synthetic colorants, so even reactive skin types can use it with confidence. Squalane, betaine, allantoin, and tocopherol (vitamin E) gently calm irritated skin, making it especially well-suited for dry and sensitive skin types.

Final step in your routine: moisture lock-in

A moisturizer is the finishing layer that seals in all the hydration you've layered on with toner, essence, and serum. Because ceramides strengthen the skin barrier, this step acts as a protective shield — preventing active ingredients absorbed in earlier steps from evaporating. Apply it last, once your serum has fully absorbed.

Use morning and night

In the morning, use it as a makeup-prepping base. At night, let it soothe and restore skin after a long day. The lightweight, non-sticky finish won't interfere with makeup application in the AM, while the rich moisture barrier helps prevent overnight water loss in the PM.

Apply gently with the right amount

Dispense a pea-sized amount onto your fingertips and dot it across your forehead, both cheeks, nose, and chin. Gently spread from the center of your face outward, and reapply to any extra-dry areas. The tube format keeps things hygienic and travel-friendly.

Recommended pairings by skin type

• Dry and sensitive skin: After prepping with a gentle toner, apply this moisturizer directly to protect and reinforce your barrier.
• Dull complexion: Layer it over a vitamin C serum for a brightening routine that delivers both glow and deep hydration.
• Loss of firmness: Pair with a peptide serum to help support a firmer, more resilient skin texture.
