LANEIGE Water Sleeping Mask is a Korean overnight-mask job candidate for Summer Fridays Jet Lag Mask. It is not the same formula.
Both products are leave-on face products that can be used overnight. That shared routine job makes LANEIGE a plausible Korean candidate for someone leaving the Summer Fridays lane. Their published textures, instructions, scent labeling, sizes, prices and formulas remain separate.
Why this exact pair is worth answering
Two separate public discussions put these names into a product-choice or dupe question: an r/AustralianMakeup dupe question asks for a less expensive option and receives a LANEIGE Water Sleeping Mask suggestion, while an r/Sephora hydration-mask question weighs Summer Fridays Jet Lag Mask’s price and rich feel against alternatives. A separate routine-use discussion supplies weaker supporting context. These are query-shape signals, not search volume, product testing, sales or profit evidence.
What Summer Fridays Jet Lag Mask actually is
| Product | Jet Lag Mask® + Moisturizer, the name used on the Summer Fridays product page |
|---|---|
| Format and directions | Multitasking leave-on product: daytime/nighttime moisturizer, short mask, overnight mask and hand/body cream; the overnight direction leaves a thin layer on before bed |
| Locked U.S. storefront snapshot | 64 g / 2.25 oz full-size variant, US$49 buy-once display; the 28 g / 1 oz mini and subscription price are outside this lock |
| Published formula and sensory signals | “Rich and nourishing” product brief; the page labels it fragrance-free and publishes niacinamide, glycerin, sodium hyaluronate and three ceramides in the ingredient list |
The exact checked Summer Fridays variant is the 64 g full-size SKU `S001-01-0002` / Shopify variant `40139555897421`. The product page also exposes smaller and collection options, so they are not silently substituted here.

Korean candidate: LANEIGE Water Sleeping Mask
| Product | Water Sleeping Mask Brighten & Hydrate, described by LANEIGE as a Korean overnight mask |
|---|---|
| Format and directions | Lightweight, refreshing gel; use it after face cream, leave it overnight and wash it off with water in the morning |
| Locked U.S. storefront snapshot | 70 mL / 2.3 fl oz, US$33 display; the page showed both “Notify Me When Back In Stock” and an Add to cart line, so availability is ambiguous |
| Published formula and sensory signals | The ingredient list includes squalane, hyaluronic-acid forms, ceramide NP, Fragrance / Parfum, limonene and linalool; this is a different published formula and label boundary |
The exact checked LANEIGE variant is Shopify variant `39550396694580` / SKU `270284223`. The Water Sleeping Mask family includes other products, including Cica and Bouncy & Firm masks; those are outside this comparison.

Same broad overnight job, different published briefs
| Summer Fridays Jet Lag Mask | LANEIGE Water Sleeping Mask | |
|---|---|---|
| Broad job | Leave-on overnight mask / moisturizer step | Korean leave-on overnight mask step |
| Checked size | 64 g / 2.25 oz | 70 mL / 2.3 fl oz |
| Displayed price | US$49 buy-once | US$33 display |
| Texture brief | “Rich and nourishing” | “Lightweight, refreshing gel” |
| Routine instructions | Can be used as moisturizer or overnight mask; leave on | Use after face cream; rinse in the morning |
| Scent and formula boundary | Summer Fridays labels the product fragrance-free; its published INCI has a different cream/ceramide system | Ingredient list names Fragrance / Parfum, limonene and linalool alongside a different gel system |
| Verdict here | Original product and its own claims | Korean overnight-mask job candidate; formula match not established |
The overlap is a broad leave-on overnight face-mask/moisturizer job. It does not make the products interchangeable. Summer Fridays’ moisturizer and hand/body directions are not transferred to LANEIGE, and LANEIGE’s Korean overnight-mask directions are not transferred to Summer Fridays.
The displayed storefronts use different units, prices, promotions and availability controls. We do not call LANEIGE universally cheaper, calculate cost per use or promise that either product is currently in stock. Shipping, tax, country, usage amount and personal preference change the decision.
Which brief does each product fit?
- Want the richer multitasking brief? Summer Fridays is the product whose page describes moisturizer, short-mask and overnight-mask uses, with its own “rich and nourishing” language.
- Want a Korean overnight mask? LANEIGE Water Sleeping Mask is the exact 70 mL candidate checked here, with its own after-cream and morning-rinse instructions.
- Is scent or labeling decisive? Read the current package. Summer Fridays’ fragrance-free label and LANEIGE’s Fragrance / Parfum ingredient entry are product-specific facts, not a prediction about every person’s response.
- Looking for treatment or a guaranteed skin result? This is a cosmetic product comparison, not a diagnosis, medical recommendation or promise of efficacy.
