Quick verdict
Same brightening actives, two formats. The Gel Mask fits a nightly routine; the peel-off Wrapping Mask gives the bigger one-night glow before an event. For most people, start with the Gel.

Medicube Kojic Acid Turmeric comes in two overnight formats that look interchangeable on a listing page and are not. One sinks into your skin and disappears. The other dries into a film you peel off in the morning. They target the same concern and suit different situations.
Here is how to pick, and — more usefully — whether either one is the right purchase at all.
The actives, and what they realistically do
Both products run on the same two headline ingredients.
Kojic acid is a tyrosinase inhibitor. Tyrosinase is the enzyme your skin uses to produce melanin, and slowing it down slows new pigment formation. It has genuine published evidence behind it for uneven tone and dark spots, and it is one of the more credible brightening actives available without a prescription.
Turmeric — specifically curcumin — is an antioxidant with anti-inflammatory activity. The evidence for topical turmeric is thinner than for kojic acid, and it is included here as much for the golden colour and the story as for measurable effect.
Now the important caveat. Brightening actives work by accumulation, not by session. Kojic acid slows pigment production over weeks of consistent exposure. An overnight mask used occasionally does not deliver that, no matter how good your skin looks the next morning.
What you get the next morning is a hydration and light-reflection effect: skin that is well-watered looks more even and reflects light more uniformly. That is real, it is visible, and it is gone in a day or two.
The Gel Mask
This is the more routine-friendly of the two. It comes in single-use pots, goes on as the last step of your night routine, and absorbs while you sleep. There is nothing to remove in the morning.
The single-use packaging is a genuine advantage and a genuine annoyance depending on your priorities. It keeps the formula stable and takes the guesswork out of how much to use. It also produces more waste and costs more per application than a tub.
Because there is no removal step, this is the one that fits into a routine you will actually keep. If your goal is consistent use over weeks — which is the only way brightening actives do anything — this is the format to choose.
The Wrapping Mask
This one dries down into a flexible film over your face and gets peeled off in the morning. The film is the point: it seals everything underneath it, so the ingredients stay in contact with your skin all night instead of partly evaporating.
That occlusion is why the immediate result tends to be more dramatic. Occluded skin holds substantially more water, and you wake up with the plumped, glossy look that these products get bought for.
It is also messier and more of a commitment. It has to dry before you lie down, and it needs removing in the morning. That friction matters more than it sounds — a product you use twice and abandon does nothing.

Which one to buy
Buy the Gel Mask if you want something you will use regularly. Lower friction, no removal step, easier to keep up over the weeks it takes for kojic acid to matter.
Buy the Wrapping Mask if you want maximum visible effect on a specific morning. It is the better pre-event product, and the occlusion genuinely does produce a bigger overnight difference.
Buy neither if your actual concern is established dark spots or melasma. Overnight masks are not the right tool. That job needs a treatment serum used every day, and — this part is not optional — daily sunscreen. Without sun protection you are removing pigment with one hand and generating it with the other.
Who should be careful
Both are marketed as low-irritation and suitable for all skin types. Treat that as a starting point rather than a guarantee.
Kojic acid can cause irritation and, less commonly, contact sensitisation with prolonged use. If your skin is reactive, patch test along the jaw for a couple of nights before putting either product across your whole face.
If you use a retinoid, do not layer either mask on top of it the same night. Alternate nights instead.
And if you are using a brightening product of any kind without daily sunscreen, you are wasting both the product and the money.
About the percentage claims
Listings for these masks quote precise improvement figures after a single use — elasticity up by one number, hydration by another. These come from manufacturer-commissioned testing on small panels over very short windows, and they are not independently verified.
They are also measuring exactly the temporary hydration effect described above. A number showing a large hydration jump after one night is entirely plausible and tells you nothing about whether the product fades a dark spot over two months.
FAQ
Can I use these every night?
The Gel Mask, generally yes. The Wrapping Mask is better a few times a week — nightly occlusion can leave some people congested. Either way, start at two or three nights a week and increase if your skin is comfortable.
How long before I see anything?
Hydration and glow: the next morning. Actual tone change from the kojic acid: eight to twelve weeks of consistent use, if it happens at all. Be suspicious of any product promising visible fading in days.
Will turmeric stain my skin or pillowcase?
Cosmetic formulations use refined turmeric extract at low concentration, so staining is uncommon. The Wrapping Mask carries slightly more risk simply because it sits on the surface rather than absorbing — use an older pillowcase the first couple of times.

The bottom line
Between the two, the Gel Mask is the better default. It fits a routine, and routine is what actually makes brightening actives work.
The Wrapping Mask is the better occasion product, and it is genuinely good at that — just do not expect an occasional peel-off mask to change your pigmentation. For that, the boring answer is a daily serum and sunscreen, and it will outperform both of these every time.
