A mask serum is a leave-on skincare product that pairs the fluid texture of a serum with the moisturizing purpose of a sleeping mask. It is not a sheet mask and does not need to be peeled off. Apply it after cleansing and toner, before cream, as a hydration-focused layer.
No.6 uses glacier water and several forms of hyaluronic acid in a light, watery formula. It can be layered when your skin needs a little more moisture, including before bed. The emphasis is a comfortable, hydrated finish rather than exfoliation, cleansing or an opaque coating on the skin.
Glacier water and hyaluronic acid in a fluid dropper serum
The formula brings together a water-rich base, humectants and skin-conditioning ingredients. Its texture is central to the format: it spreads readily and is intended to feel light rather than forming the thick layer associated with some overnight masks. The bottle dispenses the serum through a dropper.
- 63% glacier water: The brand identifies glacier water as the main base of this formula. This distinguishes No.6 within the numbered serum range without making it a substitute for the rest of your skincare routine.
- Five-part hyaluronic acid complex: Sodium hyaluronate, hydrolyzed hyaluronic acid, hyaluronic acid, sodium hyaluronate crosspolymer and hydrolyzed glycosaminoglycans accompany the water-rich base. These moisturizing components support the product's hydration-focused positioning.
- Additional humectants: Glycerin, butylene glycol, propanediol and sodium PCA contribute to a formula designed around moisture. Panthenol and niacinamide are also present in the ingredient list.
- Lightweight consistency: The watery serum is designed for a non-sticky finish and layering. It is a liquid skincare step, not a rinse-off mask, scrub or peel.
- 50mL bottle: The dropper format lets you dispense the amount needed for your face and spread it gently without a separate sheet or mask applicator.
A comfortable moisture boost without a heavy mask texture
No.6 focuses on how dry-feeling skin looks and feels during an everyday routine. It is particularly relevant when you want extra hydration but prefer a light serum to a dense cream or a single-use sheet mask. The brand positions it for morning use as well as overnight care.
- Helps relieve a dry feel: The combination of humectants supports hydration, helping skin feel more comfortable and less tight after earlier cleansing steps.
- Leaves skin feeling supple: Moisturizing care helps soften the feel of dry skin. The aim is a smoother, more comfortable surface rather than abrasive texture removal.
- Supports a fresh-looking finish: Hydrated skin can look less dull and more refreshed. This serum does not add coverage, shimmer or a tinted finish.
- Fits a layering routine: Its light consistency makes it straightforward to follow with cream. Apply a lighter first layer and add another when needed rather than relying on one heavy application.
- Works around your schedule: Use it as a morning hydration step or before bed according to the brand's guidance. There is no sheet to remove or separate rinsing stage.
- Keeps application simple: The fluid format offers mask-style moisturizing care in a familiar serum step, useful when a lengthy treatment routine is not what you want.
