The full review.
Makeup artists keep Peter Thomas Roth’s Cucumber Gel Mask in their kits for reasons beyond its shelfie-ready green color. It works when a model’s skin is inflamed from hot studio lights or a bride’s face is blotchy from nervous flushing. It calms skin fast, hydrates deeply, and works under makeup. This mask has served that purpose for nearly two decades.
The formula contains ten plant extracts: cucumber, pineapple, papaya, bilberry, sugar maple, sugar cane, orange, lemon, mango, chamomile, and aloe vera. The combination follows a logic. Cucumber, chamomile, and aloe vera provide the soothing base. Fruit extracts (papaya, pineapple) add gentle enzymatic activity. Sugar-derived extracts (bilberry, sugar maple, sugar cane) provide natural alpha hydroxy acids at low concentrations to brighten without irritation. The formula performs several gentle tasks rather than one aggressive one.
The texture is distinctive. The electric green gel is bouncy, jelly-like, and springy. It spreads easily and stays put without dripping while you walk, cook, or watch television. The cooling sensation is immediate and increases if you store the jar in the refrigerator. A chilled layer of this mask feels like jumping into a pool after sun exposure or on a hot summer evening.
Sodium PCA is a key detail. It is a component of the skin’s natural moisturizing factor—the humectant cocktail healthy skin uses to stay hydrated. This means the mask supplements the skin’s own hydration mechanisms instead of just sitting moisture on top. Combined with glycerin and water-rich botanical extracts, the hydration replenishes rather than coats.
Allantoin performs important work. As a skin protectant and gentle keratolytic, it soothes irritation and promotes healthy cell turnover. It is a common ingredient in effective soothing formulations. In this mask, it bridges the calming botanicals and the mild resurfacing fruit enzymes.
The citrus extracts—lemon and orange—are notable. These contain compounds that can be photosensitizing and irritating to reactive skin. In this formula, concentrations are low enough for most skin types to tolerate, especially since the mask is rinsed off. However, note this if your skin reacts to citrus or has acute sensitivity.
The artificial coloring is a minor issue. Yellow 5 and Blue 1 dyes create the green color, not the cucumber. This is a cosmetic choice that is functionally irrelevant but slightly conflicts with the natural botanical positioning. Ingredient purists will notice it.
Performance drives the loyal following. After ten minutes, rinse with cool water to find skin that looks calmer, feels hydrated, and has a subtle, healthy luminosity. The enzymatic fruit extracts leave skin slightly smoother without the tightness or peeling of chemical exfoliation. This mask makes skin look well-rested.
The mask is versatile. Use it as a ten-minute rinse-off mask, a thin overnight sleeping mask, a chilled after-sun treatment, or a layer over sheet masks. You can also apply it to the decolletage and backs of hands. The five-ounce jar lasts months because a little goes far.
At fifty-five dollars, this is prestige skincare. The generous size and many use cases lower the per-application cost. The value is questionable if you expect clinical results; this mask will not fade hyperpigmentation, rebuild collagen, or treat acne. It makes skin feel calm and beautifully hydrated.
Peter Thomas Roth has flashier masks like the gold, pumpkin enzyme, and sulfur options. The Cucumber Gel Mask is the quiet, frequently repurchased member of the collection. It is simple, refreshing, and exactly what you need.

The science.
The Science
The Cucumber Gel Mask uses traditional botanical soothers and a mild enzymatic resurfacing system instead of cutting-edge clinical actives.
Cucumber fruit extract (Cucumis sativus) has cucurbitacins, caffeic acid, and flavonoids that show anti-inflammatory and antioxidant activity. A 2011 Fitoterapia study shows cucurbitacins are potent anti-inflammatory compounds that inhibit cyclooxygenase-2 (COX-2) activity—the same inflammatory pathway ibuprofen targets. Topical cucumber fruit extract in a cosmetic product has lower concentrations than research-grade isolated compounds, but the anti-inflammatory mechanism is pharmacologically plausible.
Chamomile (Chamomilla recutita) has two key active compounds: alpha-bisabolol and chamazulene. A 2010 review in Molecular Medicine Reports documented bisabolol's anti-inflammatory, antimicrobial, and skin-soothing properties. This formulation uses both chamomile extract and chamomile essential oil to include both water-soluble and oil-soluble chamomile actives.
The fruit enzyme complex—papaya (papain) and pineapple (bromelain)—provides gentle proteolytic exfoliation. These enzymes break peptide bonds in dead keratinocytes without disrupting the stratum corneum lipid matrix, resurfacing more gently than chemical AHAs. The sugar-derived extracts (bilberry, sugar maple, sugar cane) contain natural alpha hydroxy acids—glycolic, lactic, citric, malic, and tartaric acids—at concentrations that provide mild keratolytic activity without significant irritation.
Sodium PCA, a pyrrolidone carboxylic acid sodium salt, is a key component of the skin's natural moisturizing factor (NMF). Research in the International Journal of Cosmetic Science shows topical application of NMF components like sodium PCA restores hydration in dry skin by mimicking the skin's innate humectant system.
The FDA classifies Allantoin as a skin protectant. It has documented keratolytic and cell-proliferative properties that promote wound healing and skin renewal while soothing irritation.
Dermatologist Perspective
Dermatologists and estheticians often recommend soothing botanical masks for recovery after chemical peels, microdermabrasion, and laser treatments. Board-certified dermatologists note that cucumber, chamomile, and aloe vera provide a multi-pathway anti-inflammatory effect that reduces post-procedural erythema and discomfort. The gentle enzymatic activity from papaya and pineapple extracts is usually well-tolerated on sensitized skin, though practitioners typically advise waiting 24-48 hours after aggressive procedures before applying any topical product. Dermatologists like the paraben-free reformulation and the use of sodium PCA as a biomimetic humectant, but they note the citrus extracts are unnecessary for a soothing product.
Where it fits in your routine.
Apply a thick, even layer to clean skin, avoiding the eye area. Leave on for 10 minutes, then rinse with cool water. Refrigerate the jar before use for more cooling. Use as a sleeping mask by applying a thin layer and leaving it on overnight. Use 2-3 times per week, or when skin feels irritated, overheated, or dehydrated. It works well after sun exposure, waxing, or post-procedure.
At $55 for 5.1 oz, the per-use cost is reasonable—about $1-2 per session over 4-6 months of regular use. The large jar size makes this a high-value option in the PTR mask lineup. However, the ingredient list lacks rare or expensive components. Comparable botanical hydrating masks cost less. You pay for the specific botanical balance, the refined gel texture, and the PTR brand assurance. The per-use economics work for year-round users. For occasional users, the price is high for a well-made cucumber and chamomile gel.
This works for anyone with sensitive, easily irritated, or dehydrated skin seeking a reliable soothing treatment. It suits post-sun care, post-procedure recovery, and calming routines that use active ingredients like retinoids or acids. Makeup artists and estheticians can use it for skin prep.
This is a soother, not a corrector for aggressive anti-aging or acne-clearing results. Use caution if you have documented citrus sensitivities, as the formula contains lemon and orange extracts.

The backstory.
The Cucumber Gel Mask is one of Peter Thomas Roth's original and most enduring formulations, dating back to the brand's early years. Inspired by the spa tradition of placing cucumber slices on the eyes, PTR built an entire face mask around the cooling, soothing properties of cucumber extract. It became a cult favorite among makeup artists and estheticians who use it to prep irritated skin before events or calm clients after procedures.

Common myths.
Cucumber in skincare provides no real benefits and is just a gimmick.
Cucumber fruit extract has documented anti-inflammatory compounds like cucurbitacins, caffeic acid, and vitamin C. It lacks the potency of clinical actives like niacinamide or retinoids, but its antioxidant and soothing properties are real and backed by preliminary research and traditional use.
Leave gel masks on for 30+ minutes to see results.
This mask delivers soothing and hydrating benefits within 10 minutes. You can apply it longer to increase hydration, but the active botanicals and humectants work immediately on contact.
FAQ.
Can I use the Peter Thomas Roth Cucumber Gel Mask as a sleeping mask?
Yes — apply a thin layer before bed and leave it on overnight for hydration. The lightweight gel formula absorbs well and does not transfer heavily onto your pillowcase. Rinse off in the morning and follow with your daytime routine.
Is this mask good for sunburned skin?
Cucumber extract, aloe vera, and chamomile make this mask effective on sun-irritated skin. Refrigerate the jar to increase the cooling effect. If your sunburn has blisters, consult a doctor before applying any skincare products.
Does the Peter Thomas Roth Cucumber Gel Mask contain parabens?
The current formulation is paraben-free and uses phenoxyethanol, potassium sorbate, and sodium benzoate as preservatives. Earlier versions of this product contained parabens. If you buy from an authorized retailer, you get the updated formula.
Why is this mask green?
Yellow 5 (CI 19140) and Blue 1 (CI 42090) dyes create the bright green color, not the cucumber extract. These cosmetic colorants add aesthetic appeal. Most people tolerate them well, but those with extreme dye sensitivities should be aware.
Can I use this mask after a chemical peel or microdermabrasion?
Estheticians use this mask for post-procedure care because its botanical formula soothes skin. Wait at least 24 hours after aggressive procedures and check with your practitioner. The citrus extracts in the formula sting freshly treated, compromised skin.
How often should I use the Cucumber Gel Mask?
Use this two to three times per week to keep skin hydrated and calm. Use it as needed when skin feels irritated, tight, or overheated. The gentle formula is safe for daily use if your skin tolerates it.
