RETURNU Deep Comfort Mask

A comforting hydration reset for cold, dry days. Created by a husband-and-wife team who left the Korean beauty industry to start their own label, this ampoule-rich mask combines birch sap, ceramides and 1,000ppm panthenol to hydrate deeply and help stop moisture escaping. Each sheet holds the equivalent of a full bottle of ampoule, on a cloud-soft, biodegradable sheet gentle enough for sensitive skin.

Why we picked it

This mask was made for the cold, dry months, when skin turns tight and flaky. That's exactly why we chose it.

Birch sap, ceramides and 1,000ppm of panthenol deliver deep hydration and help stop moisture escaping. Each sheet holds the equivalent of a full bottle of ampoule, and the biodegradable sheet is cloud-soft and gentle enough for sensitive skin.

From the shelves of Bloomingdaleʼs New York to your home, this mask has been gaining popularity with American skincare enthusiasts. Created by a husband and wife duo who left executive jobs in the Korean Beauty Industry to create their own label with one simple goal: natural ingredient products that are a “positive turning point for the skin”. The Deep Comfort Mask is the first, with more to come. A deeply hydrating mask created for the cold, dry winter months when skin becomes tight, flaky, and dry. This ampoule-rich sheet is infused with Birch Sap, Ceramide, and 1,000 ppm of Panthenol, an ingredient that helps lock in moisture and prevent it from evaporating. Containing the equivalent of a full bottle of nourishing ampoule, it delivers instant and long-lasting hydration, leaving the skin feeling soothed and replenished. Made with an eco-friendly, biodegradable sheet, it has a cloud-soft, gentle fit that is ideal even for sensitive skin. Enjoy a fresh, dewy glow from the moment it touches your face.

Best for

Dry, tight or flaky skin, especially in the colder months. Gentle enough for sensitive skin.

When we’d use it

During a quiet evening. Make it part of a routine that feels good, not another step you have to do.

What caught our attention

The amount of ampoule. Each sheet holds the equivalent of a full bottle, so skin gets a generous, lasting dose of hydration rather than a quick hit.

What we love about the brand

ReturnU was founded by a husband-and-wife duo who left executive roles in the Korean beauty industry to create their own label. Their goal is natural-ingredient products that are 'a positive turning point for the skin', and you can feel that care in every formula.
