Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate benefits for your oily skin, as glycerin and hyaluronic acid provide hydration and a plumping effect, though it lacks sufficient ingredients for optimal oil control.
- The presence of snail secretion filtrate and allantoin ensures a soothing and nourishing experience, making it generally well-tolerated for your skin type.
- The safety profile is excellent, with no risks of irritation due to the absence of harsh ingredients and the inclusion of calming components.
How to apply
- Could be used as part of your AM or PM routine. Start using your sheet mask 3 times a week and increase if your skin likes it.
- Apply your sheet mask after cleansing and toning, but before putting on your moisturizer.
- Place the sheet mask smoothly over your face and gently press it down without rubbing.
- Put the mask on clean and slightly dry skin for the best results and comfort.
- Avoid the eye area and do a simple patch test before using it for the first time.

Questions and answers
How well does COSRX Glass Glow Hydrogel Mask work for oily skin?
This mask works reasonably well for oily skin, giving you hydration and a soothing feel without clogging pores or causing irritation. However, it lacks enough ingredients that specifically control oily shine, so an oily skin type needs a product that includes targeted oil-controlling and clarifying ingredients along with the soothing and hydrating agents.
Which ingredients make this mask a good fit for oily skin?
Glycerin and hyaluronic acid help provide hydration and a plumping effect, while snail secretion filtrate and allantoin soothe and nourish your oily skin. Because it lacks sufficient ingredients for optimal oil control, a nourishing mask for this skin needs more targeted ingredients that specifically reduce oily shine and promote clarity without adding excess oil.
What does Snail Secretion Filtrate do for oily skin?
Snail Secretion Filtrate helps calm and clear oily skin while keeping it feeling soft and smooth. It may also help reduce breakouts and support skin recovery without feeling heavy or greasy.
What does Collagen do for oily skin?
Collagen helps keep oily skin hydrated and balanced without adding heaviness. It improves overall skin condition and helps maintain moisture levels, but an oily skin routine also needs ingredients that control excess oil and clear pores.

Where does this mask go in a skincare routine for oily skin?
This nourishing mask fits into your weekly routine after cleansing and before toning, or whenever your skin needs extra hydration and soothing care. It is generally well-tolerated and safe from irritation, though oily skin of this type needs additional oil-controlling ingredients for an ideal fit.
Can I use this mask with retinol, and in what order?
You can use this mask in the same routine as retinol, applying it after your retinol treatment to help soothe and hydrate your skin. This product is generally well-tolerated and unlikely to cause irritation, though oily skin requires products with specific oil-control ingredients to work best.
How often should I use this mask?
This mask works well for your oily skin as an occasional treat, offering soothing hydration without irritation. To best care for oily skin, you need a product that also provides sufficient oil control.
Can this mask clog pores, cause breakouts or purging for oily skin?
This mask is unlikely to clog pores or cause breakouts for oily skin, as it has an excellent safety profile with no harsh ingredients and includes calming components. However, because it is an average fit for oily skin, a product of this type needs added oil-controlling ingredients to properly manage shine.
Is this mask fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
