Exosome Sheet Mask: How INKEY’s Dry Sheet Mask Delivers Glow in 10 Minutes

The Exosome Boosting Dry Sheet Masks are an ultra-thin, biodegradable sheet mask that you activate yourself with water, wear for 10 minutes and remove. That is the whole commitment. Unlike most sheet masks, this one does not arrive pre-soaked in essence. It arrives dry, folded flat in a single-use sachet, and it comes to life the moment it meets wet skin.

One point of precision before anything else. This is an exosome-boosting mask. It is formulated to help support the visible glow benefits people associate with exosome skincare, and it is not the same formula as our Exosome Glow Serum. We will be clear about that distinction throughout, because it matters.

This article covers what a dry sheet mask actually is, what is inside ours, how to use it so it performs properly, and where it fits alongside the rest of your routine.

What Is an Exosome Sheet Mask?

An exosome sheet mask is a sheet mask designed to support the visible glow and hydration benefits associated with exosome skincare. It is a category that has grown quickly, driven by interest in glow-focused formulas and a finish that looks fresh rather than heavy.

Exosomes themselves are a well-known ingredient in glow skincare, and rather than repeat the full explanation here, you can read exactly what exosomes are on our ingredient page. If you want the deeper background, Exosomes Explained: Inside Skincare’s Tiniest Delivery System goes further into where they come from and why the ingredient earned its reputation.

Here is the honest part. INKEY’s mask is exosome-boosting. It does not contain exosomes itself. The product in our range that contains Cica-derived exosomes is the Exosome Glow Serum. Two different formulas, two different jobs.

So why still call it an exosome sheet mask? Because it is formulated to work alongside and support the glow results people are looking for from exosome skincare. It sits within that routine rather than duplicating it. We would rather tell you that plainly than let a name do work the formula was never designed to do.

Which brings us to the thing that genuinely makes this mask unusual, and it is not the ingredient list. It is the format.

Dry Sheet Mask vs Traditional Sheet Mask

Most sheet masks arrive pre-soaked. You open the sachet, unfold a saturated sheet, position it, and manage the run-off down your neck for the next 20 minutes. It is a format that has been around for a long time and it works perfectly well for a lot of people.

Ours works differently. The Exosome Boosting Dry Sheet Masks arrive as an ultra-thin, biodegradable dry film. There is no liquid in the sachet at all. You add the water yourself, at the moment you use it.

How SILAFILM Changes the Fit

The sheet is made using SILAFILM, an ultra-thin biodegradable film. Dry, it feels almost like a sheet of tissue. Once it is wet, it softens and moulds to the contours of your face like a second skin, sitting flush around the nose, the eye area and the jawline rather than bridging across them.

That fit is the practical difference you notice first. A mask that sits properly against the skin is a mask you can move around in.

What You Actually Notice

• No mess and no drip. There is no reservoir of essence to squeeze out and nothing running into your collar.
• No slipping. Once smoothed into place, it stays put, so you are not repositioning it every two minutes.
• Lightweight and cooling. The film is thin enough to be barely there, and the water activation gives it a genuinely refreshing feel on application.
• Easy to travel with. No liquid in the sachet means it packs completely flat, in a handbag, a carry-on or a hotel washbag.

The Water Step Is Not Optional

This is the part worth flagging early. Because the mask arrives dry, the water you add is what makes it work. Skin needs to be properly wet, not lightly damp, before the sheet goes on. A Hydrating Face Mist is the easiest way to get there when there is no sink nearby, and it doubles up later in the wear time.

Get the water right and the mask performs. Get it wrong and it will not. We have given the full technique its own section further down, because this single step accounts for most of the difference between a mask that delivers and one that disappoints.

The format also means the film is biodegradable and each mask comes individually sachet-packed for single use, which keeps it hygienic and portable.

Now, what is actually on the sheet.

What’s Inside INKEY’s Exosome Boosting Mask

Ingredient transparency is the reason INKEY exists, so here is the composition and, more usefully, what each part of it means for what you see in the mirror.

Glycerin leads the formula, and it earns that position. It is one of the most well-established humectants in skincare, which means it draws in moisture and holds it in the skin. It is not a trend ingredient. It is the reason the mask leaves skin feeling hydrated and comfortable rather than tight. If you want the full explanation of how humectants behave, we have covered it in What Is a Humectant? The Complete Skincare Guide, and there is more detail on glycerin itself on our ingredient page.

SILAFILM is the ultra-thin biodegradable film the mask is built on. It activates with water and fits like a second skin, and that comfortable, close fit is what makes a 10-minute wear easy rather than fiddly.

OXYGESKIN is a flower-derived active. What you see is skin that looks fresher, brighter and more radiant after use.

p-REFINYL visibly smooths and refines the look of skin, so the surface appears more even and better in texture.

Hydroxyethyl Urea, Lentil Seed Extract and Tropaeolum majus Extract round out the formula as supporting hydrating and skin-conditioning ingredients.

Worth restating once, briefly, and then we will leave it: this formula supports glow rather than containing exosomes.

Taken together, the result the mask is designed for is straightforward. Smoother-looking skin. A fresher, more radiant appearance. Skin that feels hydrated and comfortable rather than coated. It is a hydrating face mask first and foremost, which makes it particularly relevant if you are dealing with dehydrated skin, the kind that looks dull and feels tight regardless of whether you would call yourself oily or dry.

Composition is one thing. Here is what distinguishes our version of this format.

What Makes INKEY’s Dry Sheet Mask Different

It takes 10 minutes. That is a deliberate design choice, not a shortcut. Plenty of people will not commit to a long, multi-step routine, and a mask that asks for a quarter of an hour on the sofa is a mask that stays in the drawer. Ten minutes fits into a morning before work or the gap while the kettle boils.

You control the activation. Wetting the skin yourself makes the application feel like something you are doing rather than something you are applying. It is also genuinely cooling and refreshing, which is a small thing that makes a real difference to whether you reach for it again.

It fits like a second skin. Once activated, the film moulds to the face rather than sitting on top of it, so you get a comfortable wear instead of a slipping mask you have to keep adjusting.

It is biodegradable, mess-free and built for travel. The single-use sachet packs flat and there is no liquid to leak.

Who It Suits

The mask is non-comedogenic, vegan, and suitable to use during pregnancy and whilst breastfeeding. Honesty on one point: it has not been specifically tested on sensitive skin, so if your skin is reactive, patch test first. If you are not sure what category you fall into, What’s Your Skin Type? is a useful starting point.

An INKEY Lab Innovation

This mask came out of INKEY Lab, which is where we test newer formats and newer ingredients with our community before they become part of the core range. It is the same place our PDRN Serum came from, another recent launch aimed at people chasing glow. If you are weighing up the newer glow ingredients against each other, What is PDRN?covers the background, and PDRN vs Exosomes: What’s the Difference and Which Does Your Skin Need? sets the two side by side.

Knowing what it is only gets you so far. Technique is where sheet mask disappointment usually comes from.

How to Use a Sheet Mask: Step by Step

A dry sheet mask only performs if it is wet enough. Follow these steps in order.

1. Cleanse first. Use a gentle, non-stripping cleanser to clear away makeup, sunscreen and the day. Our Oat Cleansing Balm works well here because it removes without leaving skin feeling stripped.

2. Wet your skin thoroughly. This is the critical step. Not damp. Properly wet, with visible moisture droplets sitting on the surface of the skin. Splash with water at the sink, or use a Hydrating Face Mist until the skin is genuinely wet. Underwetting is the single most common reason a dry sheet mask underdelivers.

3. Apply the mask. Unfold it, position it over the face, then smooth it out from the centre outwards. You are pushing out air pockets and getting full contact around the nose, chin and hairline.

4. Re-moisten at 3 minutes. Go over the mask with a wet cotton pad or a few passes of mist. Do not skip this. It keeps the mask working across the full wear time.

5. Remove at 10 minutes. Peel the sheet off and massage whatever remains straight into the skin. Do not rinse.

6. Follow with your treatments, then moisturiser. Bio-Active Ceramide Moisturiser seals everything in. In the morning, finish with Dewy Sunscreen SPF 30.

Frequency. Two to three times a week suits most people, and you can use it more often when skin needs a boost. If you are masking regularly, the Pack of 6 is the better value option.

Travel tip. No sink, on a flight, or in a hotel room at midnight? Spray skin generously with a mist until it is fully wet, then apply as normal. The mask does not care where the water comes from, only that there is enough of it.

For the wider structure around this step, The Complete Skincare Routine Guide lays out the full order of operations.

Where the Exosome Mask Fits in Your Routine

Timing. Morning or evening, whenever skin needs a boost. It is a good call before an event, after a long flight, or on the mornings when skin looks dull and tired and nothing is sitting right.

Order. After cleansing, before serums and moisturiser.

Pairing It With the Exosome Glow Serum

Apply Exosome Glow Serum before the mask. This is the product in the range that contains Cica-derived exosomes, and it is a CEW UK Beauty Awards Winner 2026.

The serum delivers 6-in-1 skin rejuvenation: clinically proven to visibly improve radiance, hydration, tone, firmness, elasticity, and texture. It is also proven to deliver up to 12-hours of hydration**, and delivers clinic worthy rejuvenated skin in 14 days. In testing, 100% saw more glowing skin, clinically proven*.

To restate it once more: the serum and the mask are different formulas. The serum contains the exosomes. The mask is exosome-boosting. They are designed to work well together, which is the whole point of using them in sequence.

Layering With Actives

You can follow the mask with serums containing retinol, AHAs, BHAs or vitamin C. The mask is a hydrating step, so it plays nicely with the rest of your routine rather than competing with it. If you use Retinol Serum, apply it after the mask has been removed and the excess massaged in.

If layering makes you nervous, Skincare Ingredients You Should Not Mix covers the combinations worth thinking about, What Not to Mix with Retinol: Ingredients to Avoid handles the most common question we get, and Glycolic Acid and Vitamin C: How to Layer Them the Right Way is for anyone running multiple actives at once.

Hydration Layering

Hyaluronic Acid Serum works before or after the mask, whichever suits your routine, and hyaluronic acid pairs naturally with the glycerin in the formula. Finish with moisturiser to lock it in. If you want ceramides and peptides in that final step, the Bio-Active Ceramide Moisturiser covers both.

Who Gets the Most From It

Dull, tired-looking or dehydrated skin. Anyone whose skin has lost its bounce after travel or a bad week of sleep. And anyone chasing a glass skin finish, in which case this works as a glass skin mask within a wider routine. How to Get Glass Skin: What It Is and the Full Routine walks through the rest of it.

If your skin is currently stressed or reactive, it is worth reading up on a damaged skin barrier and redness before adding anything new. As a face mask for glowing skin, this one is built around hydration, which is usually the right place to start.

The Short Version

The Exosome Boosting Dry Sheet Masks are a dry sheet mask you activate with water and wear for 10 minutes. The technique is simple and it matters: wet your skin properly, apply and smooth outwards, re-moisten at 3 minutes, then remove and massage in whatever is left.

It is an exosome-boosting formula, designed to support visible glow, and it is not the same thing as our Exosome Glow Serum. Used together, the serum first and the mask on top, they make a straightforward glow routine that takes very little time.

Try it with the Exosome Boosting Dry Sheet Masks - Pack of 3, or pick up the Pack of 6 if you plan to mask a few times a week. Not sure where it fits? Build Your Own Routine or take our skincare quiz and we will point you in the right direction.
