Sheet Mask Lineup: Hyaluronic Acid vs Vitamin C vs Salicylic Acid

Sheet masks aren't a gimmick, they're a delivery method. A soaked bamboo fibre sheet holds a serum-strength dose of active ingredient against your skin for fifteen to twenty minutes, which is far more contact time than you get from a serum you rub in and move on from. We make three: Hyaluronic Acid for dehydration, Vitamin C for dullness and dark marks, and Salicylic Acid for breakouts and oil. They target different problems, so picking the right one matters more than picking the popular one.

What a sheet mask actually is

Strip away the marketing and a sheet mask is two things: a fibre sheet and the serum it's soaked in. The fibre's job is simple, it holds the serum flat against your face and stops it evaporating, so the active has time to actually absorb instead of sitting on the surface for thirty seconds before you towel it off.

Ours are cut from biodegradable bamboo fibre and made in Korea, where sheet mask production has been refined for decades. Bamboo fibre is finer and more pliable than cotton or synthetic alternatives, so it moulds to the contours of your face instead of gapping at the nose and jaw, and it breaks down after disposal instead of sitting in landfill for centuries the way a plastic-fibre sheet does. Every GloPotion order also puts 1% toward reforestation and carbon removal through Ecologi, so the sustainability angle isn't just the packaging, it runs through to what happens after you use the mask. You can see the full range under sheet masks, and everything made in Korea across the GloPotion range sits under Made in Korea.

Hyaluronic Acid Bamboo Sheet Mask: for dehydration

Hyaluronic acid is a humectant. It doesn't add oil to your skin, it pulls water into it and holds it there, which is exactly why it works on every skin type including oily and acne-prone skin. Dehydration and oiliness aren't opposites, plenty of oily skin is also dehydrated, and this mask fixes the water side of that equation without adding any grease.

Reach for this one when your skin feels tight, looks dull from lack of moisture rather than lack of glow-boosting actives, or after a day of aircon, flying, or sun exposure that's pulled moisture out of the surface. In our independent consumer questionnaire of 20 participants, skin still felt hydrated 48 hours after a single use, and participants reported their skin looked smoother and hydrated straight after the first application. It's R55.99 and pairs naturally with the Hydrating Complex 5% + Hyaluronic Acid Serum for anyone building out a hydration-focused routine, or browse the full hyaluronic acid range.

Vitamin C Bamboo Sheet Mask: for dullness and dark marks

Vitamin C is an antioxidant and a tyrosinase inhibitor, meaning it interferes with the enzyme pathway your skin uses to produce excess pigment. That's the mechanism behind fading dark marks and evening out tone, and it's also what gives skin that brighter, less flat look after use, because it's counteracting the free radical damage that leaves skin looking tired.

This is the mask for post-summer or post-breakout pigmentation, for skin that looks a bit grey or flat rather than fresh, and for anyone prepping for an event where they want a visible brightness lift without committing to a full routine change. As spring moves toward more sun exposure, this is also a good one to keep in rotation, since UV exposure is one of the main drivers of new pigmentation. It's proven to brighten skin and participants in our consumer questionnaire reported reduced dark spots, more even tone, and improved skin texture, with skin left hydrated and glowing. R55.99, and if pigmentation is an ongoing concern rather than an occasional one, the Vitamin C 5% Serum is the daily version of the same active. See more under pigmentation.

Salicylic Acid Bamboo Sheet Mask: for breakouts and oil

Salicylic acid is a beta hydroxy acid, and unlike alpha hydroxy acids it's oil-soluble, so it can get into the pore lining itself rather than just working on the surface. That's what makes it effective on blackheads and the kind of breakouts that sit under the skin, it dissolves the buildup of oil and dead skin cells that clogs the pore in the first place, and it has calming properties that help with the redness that comes with active breakouts.

Use this one when you've got active breakouts, congestion around the nose and chin, or oily patches that need mattifying without stripping the skin dry. It reduces the appearance of pimples and blackheads, visibly reduces shine and redness, and hydrates without leaving skin feeling oily, so it doesn't trade breakout control for a dry, tight finish the way some clarifying products do. R55.99. For daily maintenance alongside occasional masking, the Salicylic Acid 2% Serum covers the same active in a leave-on format, and the full range is under salicylic acid or oily skin.

How to actually use a sheet mask

The active only works if the sheet stays in contact with your skin, and most of the benefit is lost if you rinse it off straight after or skip the last step.

1. Cleanse first. Use the Oat Cleansing Gel or your usual cleanser so the serum is absorbing into clean skin, not sitting on top of the day's oil and sunscreen.
2. Unfold and smooth it on. Line up the eye and mouth openings first, then press the sheet flat against your cheeks, forehead, and jaw so there's no air trapped underneath.
3. Leave it for 15 to 20 minutes. Longer than that and the sheet starts drying out and can actually pull moisture back off your skin instead of giving it up, so don't fall asleep in it.
4. Take it off and don't rinse. There's still a layer of serum sitting on your skin when you peel the sheet away, and that's the part doing the ongoing work. Rinsing it off undoes a chunk of what you just did.
5. Press in what's left in the packet. There's always extra serum pooled in the sheet and the pouch. Pat it into your neck, décolletage, or hands rather than letting it go to waste.
6. Follow with moisturiser to lock it in. A sheet mask isn't a replacement for your moisturiser step, it's a boost before it.

Which one to reach for

If your skin feels tight, flaky, or just thirsty, go Hyaluronic Acid. If it looks dull, uneven, or you're dealing with marks left over from old breakouts or sun exposure, go Vitamin C. If you've got active spots, blackheads, or oily congestion right now, go Salicylic Acid. There's no rule against keeping all three on hand and picking based on what your skin is doing that week, that's exactly how we use them.

FAQ

Can I use a sheet mask every day?

You can, but two to three times a week is plenty for most people to see the benefit without overdoing it, especially with the Salicylic Acid mask, which is an active exfoliant rather than a plain hydrator.

Can I use these if I have sensitive skin?

All three are fragrance-free formulations. The Hyaluronic Acid mask is the gentlest starting point since it's purely a humectant. If you're new to actives generally, patch test on your inner arm first, the way you would with any new product.

Do I need to moisturise after, if the mask already left serum on my skin?

Yes. The serum residue is doing active work, but moisturiser adds the occlusive layer that seals moisture in and stops it evaporating over the next few hours.

Why bamboo fibre instead of a normal cotton sheet mask?

Bamboo fibre is finer and more flexible, so it hugs the contours of your face more closely than standard sheet material, which means better contact and better absorption. It's also biodegradable, so it breaks down after you're done with it instead of persisting as microplastic waste.

Can I layer a sheet mask under other products?

Use it as your first step after cleansing, then follow with your usual moisturiser or oil. There's no need to layer a separate serum underneath it, the mask is already delivering a concentrated dose.
