It is a hydrogel rather than a cotton sheet, built on 70 percent hydrolyzed collagen and 10 percent sea buckthorn water, with niacinamide and alpha-arbutin for brightening. The gel format clings without dripping and becomes transparent as it absorbs.
A luxurious-feeling collagen hydrogel mask that clings closely and leaves skin plump, dewy and visibly brighter for an evening out, helped by niacinamide and alpha-arbutin. The glutathione and retinal on the label are token amounts, though, and at about seven dollars a sheet it is best treated as an occasional glow boost rather than a brightening treatment.
Olive Young's review count pools this mask with its collagen sibling, so product-specific feedback is limited, and the evaluation relies on the declared formula. Trace concentrations of glutathione and retinal mean their contribution is judged from published research rather than measured for this mask.

Dermatory is refreshingly specific about what goes into its Retinal Glutathione Radiance Gel Mask. The pack and ingredient list state that hydrolyzed collagen makes up 70 percent of the gel, sea buckthorn water 10 percent, retinal 5ppm and glutathione 10ppm. Those numbers tell a clear story: this is a collagen hydrogel mask with a few brightening extras, and the two ingredients in its name are present in amounts measured in parts per million.
That is not a criticism of the experience, which is genuinely enjoyable. Hydrogel masks differ from cotton or pulp sheets. Rather than a fabric soaked in liquid essence, the mask is a gel set with seaweed-derived carrageenan and carob and guar gums, which holds the ingredients within its structure. It feels cool and bouncy, clings firmly to the contours of the face without dripping, and gradually turns more transparent as the skin absorbs moisture from it. After twenty to thirty minutes, skin looks plump, dewy and noticeably more luminous, the kind of result that makes a gel mask popular before events.
Where does the glow come from? Mostly from hydration. Hydrolyzed collagen at 70 percent is a powerful humectant and film-former, drawing water into the upper skin and leaving a smooth surface that reflects light evenly. Glycerin, sodium hyaluronate, betaine and panthenol support that effect. Niacinamide, fifth in the list, is the most substantial brightening active, supporting barrier function and more even tone over time. Alpha-arbutin, a tyrosinase inhibitor, adds another brightening angle, and vitamin C derivatives, bisabolol and ubiquinone appear in small amounts.
Glutathione, the mask's namesake, is present at 10ppm, or 0.001 percent. Glutathione is a powerful antioxidant inside the body, and its reputation for skin lightening comes largely from oral and injectable use in some markets, where evidence is mixed and safety concerns exist. Topical evidence is limited, and at this concentration in a mask used for half an hour, any contribution is minimal. The same applies to the retinal at 5ppm, which gives the product line its name but will not deliver retinoid effects at that level.
The mask also contains fragrance, listed last, and several emollient and emulsifying ingredients, including macadamia oil and ceteth compounds, that make it unsuitable for fungal acne routines. For most skin types, though, the formula is gentle, with allantoin, dipotassium glycyrrhizate and panthenol providing soothing support.
In practical terms, the mask works best in the evening after toner. The two-part sheet requires a little care to separate from its protective films, and aligning the upper and lower halves takes a moment. Once on, it stays in place even when moving around. After removal, patting in the residue and applying a moisturizer seals in the hydration. The glow often lasts into the next morning.
Expectations around brightening should be realistic. A single mask gives an immediate optical brightness from hydration. Regular weekly use may contribute modestly to a more even tone thanks to niacinamide and alpha-arbutin, but dark spots and melasma need consistent daily serums and sunscreen. The mask is a complement, not a treatment.
It helps to think about the mask as a stage in an evening routine rather than a standalone product. A good sequence is a gentle cleanse, a hydrating toner, the mask for twenty to thirty minutes, then a thin serum and a moisturizer to seal everything in. Because hydrogel leaves the skin well hydrated, anything applied afterward tends to spread and absorb easily, which makes the post-mask window a sensible time for a niacinamide or vitamin C serum if you already use one. That way the mask provides immediate glow, and the serum provides the daily, cumulative brightening that the mask alone cannot.
Storage can add to the experience. Keeping a couple of sheets in the refrigerator makes the gel even more cooling, which many people find soothing after sun exposure, a long flight or a late night. Cold does not change the formula, but it can temporarily reduce puffiness and make the ritual feel more restorative.
There is also a sensible caution for anyone with reactive skin: hydrogel sits very close to the skin for half an hour, which increases contact with every ingredient, including fragrance. A patch test on the jaw with a small piece of the gel before first full use is a simple precaution.
For pregnant users, the trace retinal is worth noting; many clinicians prefer to avoid retinoid-containing products during pregnancy as a precaution, even at low levels.
The review count on Olive Young is pooled with the collagen version of the mask, so product-specific feedback is harder to separate. General feedback praises the adherence, cooling feel and immediate glow, and notes the price per sheet.
Value depends on how you use it. At about seven dollars per sheet regular price, often discounted, it is more expensive than basic sheet masks. As an occasional pre-event treat, it delivers a satisfying result. As a weekly brightening routine, the cost adds up for modest long-term benefits.
For normal, dry and combination skin that wants a quick, reliable glow and enjoys the hydrogel experience, it is a pleasant choice. Anyone buying it for glutathione or retinal benefits should look instead to serums with meaningful concentrations of proven actives.

| Ingredient | Function | Evidence |
|---|---|---|
| Hydrolyzed Collagen (70%) (70%) | The gel's main ingredient, a collagen solution set with seaweed and carob gums into a hydrogel sheet that clings closely and floods the surface with humectant hydration for a plump, glassy finish. | Not yet assessed |
| Niacinamide | Fifth in the formula and the mask's most substantive brightening active, supporting even tone and barrier function during the contact time. | Limited for Dark Spots |
| Alpha-Arbutin | A tyrosinase inhibitor added for the 'radiance' claim, though a single short mask session delivers only a small dose. | Limited for Dark Spots |
| Glutathione (10ppm) (0.001%) | The namesake antioxidant, declared at just 10ppm, is a marketing-level trace rather than a meaningful brightening dose. | Not yet assessed |
| Retinal (5ppm) (0.0005%) | A trace 5ppm retinal gives the mask its 'Retinal' name; at this level it adds little beyond the label. | Not yet assessed |

PM
Apply after toner, leave for 20 to 30 minutes, then pat in any residue and follow with moisturizer. It works well the evening before an event for a plump, luminous look.
Skin looks plumper, dewier and slightly brighter immediately after use, with the glow lasting into the next day. Any tone-evening benefit is modest and cumulative with regular weekly use.
Hydrogel masks use polysaccharide gels, here carrageenan from Chondrus crispus, carob gum and guar gum, to hold active ingredients in a semi-solid matrix. Studies comparing occlusive mask formats suggest they increase skin hydration more than leaving the same ingredients uncovered, because the gel limits evaporation during contact. Hydrolyzed collagen at high concentration acts as a humectant and film-former, improving surface smoothness and light reflection.
Niacinamide inhibits the transfer of melanosomes to keratinocytes and supports barrier function; clinical studies at 2 to 5 percent in leave-on formulations show improvements in hyperpigmentation over weeks. Alpha-arbutin inhibits tyrosinase and is widely used for brightening at up to 2 percent in leave-on products. In a mask used for 20 to 30 minutes, their effects are smaller but may add up with regular use.
Glutathione is an endogenous antioxidant involved in melanogenesis regulation, and has been studied orally and topically for skin lightening with mixed results. At 10ppm, the amount in this mask is far below concentrations used in topical studies.
Retinal is a potent retinoid at 0.05 to 0.1 percent, but at 5ppm (0.0005 percent) its contribution is negligible. The formula's soothing agents, including allantoin, bisabolol and dipotassium glycyrrhizate, support tolerability.
Dermatologists generally view sheet and hydrogel masks as cosmetic, hydrating treatments rather than therapeutic ones. Their occlusive format can temporarily improve hydration and the appearance of skin, which is why they are popular before events. For patients seeking brightening, clinicians typically recommend daily use of niacinamide, azelaic acid, tranexamic acid or other proven actives, together with sunscreen, rather than relying on masks with trace doses of glutathione. The fragrance may be a concern for sensitive patients, and many clinicians advise avoiding retinoid-containing products during pregnancy as a precaution. Occasional use as a hydrating treat is unlikely to cause problems for most patients.
After cleansing and toning, open the pouch and separate the upper and lower gel halves from their protective films. Apply the upper half first, aligning the eye openings, then the lower half, pressing gently so the gel adheres. Leave on for 20 to 30 minutes until the gel becomes more transparent. Remove, pat any remaining essence into the skin, and follow with moisturizer. Use once or twice a week in the evening. Chill the pouch beforehand for an extra-cooling effect.
At a regular price of about seven dollars per sheet, the mask is on the expensive side for a single-use product, though frequent discounts improve that. The value lies in the immediate cosmetic glow and the pleasant hydrogel experience, not in concentrated actives; the glutathione and retinal are token doses. For occasional use before an event, it is a fair indulgence. For regular brightening, a daily serum offers far better value. It is typically sold as single sheets or in multi-packs.
Normal, dry and combination skin that wants a quick, reliable glow and plumpness before an event, and anyone who enjoys the cooling, clinging feel of hydrogel masks as an occasional pampering step alongside an otherwise simple, serum-led daily skincare routine.
People buying it specifically for glutathione or retinal benefits will find only trace amounts. Fragrance-sensitive skin, fungal-acne sufferers, pregnant users avoiding retinoids and budget-focused shoppers may prefer a simpler, less expensive hydrating mask for regular weekly use at home instead.

All Year
Dermatory launched its Retinal gel masks in 2023 as two variants, Collagen Lifting and this Glutathione Radiance version, extending its retinal line into quick at-home treatments.
Dermatory is a Korean dermo-cosmetic brand from the CLIO group, manufactured by Cosmax. Its retinal gel masks, launched in 2023, declare collagen percentages and retinal ppm on the pack; there is no published clinical testing of this mask.
Glutathione in a sheet mask whitens skin.
At 10ppm and a single short application, the glutathione here is a trace. Any brightening comes mainly from niacinamide, alpha-arbutin and the optical glow of well-hydrated skin.
Gel masks deliver collagen into the skin.
Hydrolyzed collagen acts as a surface humectant and film-former. It plumps the look of skin temporarily but does not replenish dermal collagen.
About 20 to 30 minutes, until the gel turns more transparent. Remove it, pat in any remaining essence and follow with moisturizer.
It gives an immediate luminous look from hydration and contains niacinamide and alpha-arbutin. Glutathione and retinal are present only in trace amounts, so long-term brightening is modest.
Both use a collagen hydrogel base. The Glutathione version adds sea buckthorn water, alpha-arbutin, glutathione and vitamin C derivatives for radiance; the Collagen version focuses on firming with bakuchiol and more collagen.
It contains a trace of retinal, a retinoid. Many clinicians advise avoiding retinoids in pregnancy, so it is best to check with a clinician or choose a retinoid-free mask.
Once or twice a week is typical. It is gentle enough for regular use, but its cost makes it more of an occasional treat.
No, fragrance is listed at the end of the ingredient list. Most people will barely notice it, but sensitive skin should patch test.
