The full review.
If you turn over a typical clay mask on the drugstore shelf, the functional base almost always reads the same way: water, kaolin, and maybe one additional clay for good measure. Kaolin is the cheap, dependable clay most brands default to because it absorbs surface oil without being aggressive about it. Bentonite shows up occasionally for stronger absorption. Beyond those two, most wash-off masks stop and lean instead on a hero active — charcoal, tea tree, sulfur, whatever the brand is marketing that season. What makes the Mary & May Lemon Niacinamide Glow Wash Off Pack genuinely interesting is that it stacks four different clays at the top of the formula. Kaolin first, then bentonite, then illite, then — lower in the list but still meaningfully present — montmorillonite. Each of those clays has a slightly different absorption profile and particle size, so you end up with layered depths of surface oil and debris lifting rather than a single absorption mode. It is the kind of formulation decision you usually see in prestige European clay masks like those from Omorovicza, not in a $14 Korean wash-off tub.
About Mary & May
Mary & May is an indie Korean brand founded in 2018 that has built its reputation on ingredient transparency and vegan formulations, and the Lemon Niacinamide mask is their vitamin-forward clay option.
Formula
The rest of the formula extends the thinking. Niacinamide sits seventh on the INCI, which typically means a 2-5% concentration — enough to work on sebum regulation and mild pigmentation during the 10-15 minute contact time. Then comes 3-O-ethyl ascorbic acid, a stable lipid-soluble vitamin C derivative that is a more sensible choice for a clay-mask vehicle than pure ascorbic acid, which would oxidize within hours of contact with clay minerals. Lemon peel powder provides the signature yellow color, the citrus scent, a trace of natural vitamin C, and a very gentle physical grit during rinse-off. Gluconolactone, a PHA, sits near the tail for light chemical exfoliation. Peach extract, tocopherol, and glycerin round out the hydration and soothing layer.
How to Use
The use experience is exactly what you would hope. You scoop out a pea-sized amount, spread a thin even layer across cleansed, dry skin, and feel the cool clay within seconds. The lemon fragrance is strong in the first minute and then settles down. After about ten minutes the mask is semi-dry but not cracked, which is the sweet spot. At that point you rewet your fingers, massage gently for ten or fifteen seconds to activate the lemon peel grit, and rinse everything off with lukewarm water. The skin immediately looks cleaner, smoother, and slightly brighter. Do not skip the hydrating toner and moisturizer step afterward — clay masks leave the skin in a thirstier state than it started, and the glow you are chasing depends on replenishing that water layer.
Works for
Over four to six weeks of consistent once or twice weekly use, the cumulative effects are real: fewer congested pores, less midday surface oil, and gradual brightening of post-inflammatory marks when the mask is paired with a niacinamide or vitamin C serum routine the rest of the week.
Not ideal for
It is not going to transform your skin in a week, but it earns its place in a rotation. The honest limitations are structural rather than formulation flaws. This mask is specifically built for oily and combination skin. If you have dry or mature skin, the four-clay stack will probably feel too absorbent, and the brightening story is better served by a leave-on niacinamide and vitamin C serum anyway. Sensitive skin, rosacea-prone skin, or anyone with a fragrance allergy should skip this one entirely — the combination of added fragrance, lemon peel powder, and citric acid is a legitimate irritation risk stack, and Mary & May’s own Centella or Green Tea wash-off masks are a better fit for that population.
Common Complaints
Overuse is the other failure mode. Twice a week is the recommended ceiling for this mask, and for most users once a week is plenty. Using a clay mask three or four times a week, especially layered with other exfoliants, is one of the most common causes of mask-induced barrier damage, and nothing in this formula protects you from that mistake.
Value
On value, this is a genuinely fair buy. A 125g tub costs around $14 on iHerb or Amazon, which works out to somewhere between 40 cents and $1 per use depending on how thick a layer you apply. For a four-clay formula with three brightening actives plus a PHA at this price point, it is one of the better clay masks in the K-beauty mass-tier.
Who Should Buy
If you specifically want a clay mask that also brightens, and you are not sensitive to citrus or fragrance, it is an easy recommendation. If you want pure pore-clarifying without any active brightening, a simpler single-clay mask is cheaper and does the same job. Mary & May has built this one for people who want the clay benefit and the vitamin benefit in the same ten-minute session.

The science.
The Science
This mask's functional base uses four clays with different particle sizes and cation-exchange capacities. Kaolin is the lightest and absorbs most from the surface, lifting sebum without aggressive pull. Bentonite and montmorillonite have a layered smectite structure and higher cation-exchange capacity; they absorb surface debris and loose dead skin more effectively, and dermatology literature supports both for oily and acne-prone skin. Illite is a non-swelling clay with a particle size between kaolin and bentonite that provides medium-depth absorption. Using all four clays in one formula is unusual for affordable wash-off products and gives this mask a stronger pore-clarifying effect than single-clay masks. Three actives drive the brightening claim. Niacinamide sits at a mid-INCI position (likely 2-5%) and has the strongest evidence base—published clinical trials show reductions in sebum production, pore appearance, and hyperpigmentation at concentrations as low as 2% after 4-12 weeks of daily use, and even short-contact wash-off use offers cumulative benefit with consistent use. 3-O-ethyl ascorbic acid is a vitamin C derivative; published data shows it converts to ascorbic acid in skin and brightens similarly to pure ascorbic acid with higher stability. Gluconolactone, a polyhydroxy acid, provides gentle surface exfoliation with significantly less irritation than glycolic or salicylic acid. The caveat for all three is that 10-15 minutes of contact time two or three times a week delivers a modest cumulative dose compared to a leave-on daily serum. The wash-off format uniquely combines clay absorption and active brightening in one session, making this mask a useful routine complement rather than a standalone treatment. No independent clinical testing on the specific Mary & May formulation has been published.
Dermatologist Perspective
Dermatologists generally view clay masks as a reasonable occasional adjunct for oily and acne-prone skin if used in moderation and followed by hydrating moisturizers. Board-certified dermatologists note the four-clay stack in this mask is more absorbent than most wash-off formulas and recommend a frequency ceiling of once or twice weekly. The niacinamide and vitamin C derivative are functional actives with good evidence bases, though clinicians emphasize that a leave-on serum at the same concentrations delivers more cumulative benefit than a wash-off format. For patients with rosacea, eczema, or sensitive skin, dermatologists typically recommend gentler unfragranced alternatives—Mary & May's own Centella variant is a reasonable substitution. The fragrance and lemon peel powder are the two ingredients most likely to cause low-grade irritation in reactive skin; consider these before adding this mask to a routine that already contains retinoids or exfoliating acids.
Where it fits in your routine.
Use 1-2 times a week, at night or in the morning before makeup. After cleansing, pat skin dry and apply a thin, even layer of the mask across the face, avoiding the eye area and lips. Leave on for 10-15 minutes — until semi-dry but not cracked. Rewet fingertips with water and massage gently in circular motions for 10-15 seconds to activate the lemon peel grit, then rinse thoroughly with lukewarm water. Follow immediately with a hydrating toner, a niacinamide or hyaluronic acid serum, and a moisturizer. Apply SPF if using in the morning.
At roughly $14 for 125g, this works out to pennies per application and makes the Lemon Niacinamide Wash Off Pack one of the better values in the affordable K-beauty clay mask category. The four-clay stack and three-active brightening roster are unusually well-developed at this price point — most sub-$15 clay masks settle for one clay and one hero ingredient. The 30g travel size is also available for users who want to test tolerance before committing to the full tub, which is a sensible move for anyone with reactive skin. Compared to prestige Western clay masks in the $40-$60 range like Omorovicza or GlamGlow, the Mary & May delivers a similar or better formulation for a quarter of the price, with the trade-off being the fragrance and slightly less elegant texture.
Oily or combination skin readers want a clay mask that brightens. K-beauty fans can use this single wash-off step instead of layering separate clay and vitamin C treatments. Budget-conscious buyers get a well-formulated wash-off mask under $15. It also works for acne-prone skin when rotated with gentler barrier-support products.
Dry, mature, sensitive, or rosacea-prone skin types find the four-clay stack too absorbent. The fragrance/lemon peel poses a moderate irritation risk. Mary & May's Centella or Green Tea wash-off variants are gentler alternatives. Skip this if you use multiple exfoliating actives; adding this mask to a heavy exfoliation routine damages the barrier quickly.
Product details.
This soft yellow clay paste has visible lemon peel flecks. It spreads easily and feels cool on application. As the water phase evaporates, the paste turns a shade paler and semi-matte on the skin.
Lemon peel powder and added fragrance create a strong, pleasant lemon-citrus scent. This scent divides users: K-beauty fans usually love it, but fragrance-sensitive users should skip it.
A 125g round plastic tub with a screw-on lid follows the format of other Korean wash-off masks. A 30g travel size exists for testing before you buy the full tub.
First use: scoop out a pea-sized amount, spread a thin even layer on cleansed dry skin, and feel a cool clay sensation within seconds. The lemon fragrance is noticeable but not overwhelming. After about 10 minutes the mask is semi-dry — do not let it fully crack — and rinses off cleanly after a brief massage with wet fingers. Skin feels tight immediately but glowy and visibly smoother once you follow with a hydrating toner and moisturizer.

The backstory.
Mary & May launched the Lemon Niacinamide Glow Wash Off Pack in 2022 as part of their vitamin-forward wash-off range, which also includes green tea, vitamin C, and centella variants. The brand designed the formulation specifically to combine the oil-control and pore-clarifying benefits of a traditional Korean clay mask with the brightening benefits of a vitamin C wash-off treatment, without requiring the user to layer two separate products. It has become one of Mary & May's consistent top-sellers on iHerb and Amazon.

Common myths.
Clay masks pull toxins out of your pores.
Clay does not detoxify the skin. When mixed with water, it absorbs surface oil, loose debris, and some superficial dead skin. Pores feel cleaner after rinsing because of mechanical absorption, not detoxification. The skin uses kidneys and a liver for detox.
A good clay mask should fully dry and crack on your face.
Letting a clay mask crack fully harms the barrier. Once the water phase evaporates, the clay pulls moisture from the skin instead of just absorbing surface oil. Mary & May recommends rinsing while the mask is still slightly tacky, usually after 10-15 minutes.
FAQ.
How often should I use the Mary & May Lemon Niacinamide Wash Off Pack?
Use 1-2 times a week for most skin types. Oily and acne-prone skin tolerates twice weekly use; dry or sensitive skin starts at once weekly to monitor barrier response. Overuse of clay masks often causes mask-induced dryness, especially when layered with other exfoliants.
Is this clay mask safe for sensitive skin?
This is not the first pick. Added fragrance, lemon peel powder, and citric acid create a moderate irritation risk for reactive or rosacea-prone skin. Mary & May's Centella or Green Tea wash-off variants are gentler for sensitive skin and provide similar clay-based pore benefits.
Can I leave this mask on longer than 15 minutes?
No. If the water phase evaporates, the clay pulls moisture from the skin instead of absorbing surface oil. Mary & May recommends rinsing while the mask is still slightly tacky, typically after 10-15 minutes depending on ambient humidity.
Does the lemon peel powder actually exfoliate?
Yes, mildly. The powder has a fine, gritty texture that exfoliates physically when you wet and massage the mask before rinsing. The gluconolactone (PHA) in the formula adds light chemical exfoliation. This combination is gentle for a clay mask.
How does this compare to the Mary & May Centella Asiatica Ampoule Wash Off Pack?
The Lemon Niacinamide version targets oil control, brightening, and pore clarification. It uses a four-clay stack, vitamin C, and niacinamide to provide more active ingredients. The Centella Asiatica version is gentler and focuses on calming and barrier support. It works better for sensitive, reactive, or post-procedure skin.
Is this mask pregnancy-safe?
Yes — the formula lacks retinoids, salicylic acid, or other pregnancy-restricted actives. Niacinamide, vitamin C derivatives, and clay are pregnancy-compatible. The fragrance and citrus scent may bother those with pregnancy-related scent sensitivity, but no ingredient-level safety concern exists.
