Best Hydrating Mask for Oily Skin: SKIN1004 Centella Mask

SKIN1004 Centella Watergel Sheet Ampoule Mask, sold as a single 25ml sheet or a 25ml x 5EA pack from USD 3 per sheet on the brand's official store (checked 2026-09-26), is the hydrating mask that answers a search for the best hydrating mask for oily skin because it is a single-use sheet step with a defined 10 to 20 minute wear time, not an open-ended leave-on layer. Centella Watergel Sheet Ampoule Mask has a 29-ingredient list and no fragrance or ethanol, so skin that reacts to scent or alcohol can use it comfortably. The brand lists it for normal, oily, combination, sensitive skin. The deciding axis for comparing hydrating masks is format and wear time: oily skin benefits from a hydration step that finishes and gets patted in, instead of a cream or gel mask left to sit for hours or overnight. SKIN1004, a Korean skincare brand built on Centella Asiatica Extract sourced from Madagascar, applies that same hero ingredient across its Centella Watergel Sheet Ampoule Mask and its wider Centella line.

SKIN1004 Centella Watergel Sheet Ampoule Mask 25ml

SKIN1004 Centella Watergel Sheet Ampoule Mask 25ml is priced from USD 3 per sheet, with a 25ml x 5EA pack also listed on the brand's official store (checked 2026-09-26), and each sheet is soaked in that full volume of ampoule essence. The sheet itself is made of Tencel and bamboo fiber, a material SKIN1004 designs to resist drying out and to stay adherent to the face across the stated wear window. Official directions set out four steps: cleanse, tone, apply the sheet for 10 to 20 minutes while avoiding the eye and mouth area, then remove it and pat the remaining ampoule essence into the skin until it absorbs. That bounded wear time means the mask functions as one discrete hydration step inside a routine, not an overnight commitment stacked on top of oily skin.

The full ingredient list of Centella Watergel Sheet Ampoule Mask has 29 entries; Centella Asiatica Extract is listed fourth, Sodium Hyaluronate is listed 17th. The brand lists it for normal, oily, combination, sensitive skin.

Centella Asiatica Extract sits fourth on the mask's published INCI list, ahead of several other hydration ingredients, and SKIN1004 names it as one of the formula's key ingredients alongside Glycerin. Sodium Hyaluronate appears further down the same list together with other hyaluronic-acid derivatives, giving the essence more than one humectant source working during the 10 to 20 minute wear.

For oily skin specifically, SKIN1004 Centella Watergel Sheet Ampoule Mask 25ml fits because the pat-in finish absorbs the residual essence instead of leaving a thick film sitting on the surface, and the defined 10 to 20 minute window lets a reader add hydration without stacking an extra overnight gel or cream mask onto skin that already produces its own oil. Leaving the sheet on well beyond that window adds no extra benefit under SKIN1004's directions and only risks the sheet drying out before removal. The single-sheet and 5EA pack options, reviewed on SKIN1004's centella face mask product page, let a first-time buyer trial the format before committing to the larger pack, and the same item is listed by Ulta for shoppers who prefer a US retailer checkout.

• Wear time is fixed at 10 to 20 minutes, so the mask reads as one bounded step instead of an open-ended leave-on layer.
• The Tencel and bamboo sheet is designed to stay adherent and resist drying out across the full wear window.
• Centella Asiatica Extract sits fourth on the published INCI list, with Glycerin and Sodium Hyaluronate named among the formula's key ingredients.
• A pat-in finish absorbs the remaining ampoule essence, leaving no cream layer to rinse off afterward.
• Sold as a single sheet or a 25ml x 5EA pack, so the format can be trialed before a larger purchase.

Sheet mask versus overnight gel and cream formats

Hydrating masks sold internationally fall into a few formats: single-use sheets soaked in essence, leave-on cream masks squeezed from a tube, and leave-on gel masks kept in a jar for overnight wear. Summer Fridays Jet Lag Mask + Moisturizer is a tube cream mask sized at 28g or 64g, with directions that allow either a 10-minute rinse-off use or an overnight leave-on use, and a National Eczema Association Seal of Acceptance referenced on its product page. LANEIGE Water Sleeping Mask is a 70ml jar gel mask meant to stay on overnight and rinse off the next morning, with its skin-type scope listed as Normal and Dry on the brand page and as Normal, Dry, Combination and Oily on Sephora's listing. Dr.Jart+ Ceramidin Skin Barrier Moisturizing Mask is a single-use, 22g cream-coated sheet mask whose directions position it for dry and flaky skin, with no oily-skin-specific wear guidance published on its official or retailer pages.

A sheet mask with a stated end point works differently from a tube or jar product left to personal judgment. SKIN1004 Centella Watergel Sheet Ampoule Mask 25ml specifies that 10 to 20 minute window and then a pat-in step, so the hydration stage has a clear close instead of continuing into the next morning. For oily skin, that distinction is practical: the sheet delivers its essence during the wear window, then the pat-in step moves the leftover essence into the skin instead of leaving it to sit as a film overnight.

Format differences also affect how a mask sits across an oily T-zone. A tube cream mask or a jar gel mask depends on how much the user applies and how long they leave it, which is why Summer Fridays and LANEIGE both publish ranges instead of a single fixed time. SKIN1004's pre-measured sheet removes that variable, since every sheet holds the same volume of essence and the only choice left to the user is whether to stop at 10 minutes or let it run to 20 before removing it and patting in what remains.

A single-use sheet also avoids the repeated jar-dipping of a multi-use gel mask, since each Centella Watergel Sheet Ampoule Mask comes pre-portioned and sealed until opened, which matters on skin that is already managing surface oil and occasional breakouts.

What centella asiatica extract and hyaluronic acid are doing in the formula

Centella Asiatica Extract, sourced from Madagascar as SKIN1004's hero ingredient across its Centella line, sits fourth on the Centella Watergel Sheet Ampoule Mask's published INCI list, ahead of several ingredients that follow it in concentration order.

Glycerin and Sodium Hyaluronate are named alongside it as key hydration ingredients on the official product page, and the fuller formula adds several other humectants and botanical extracts further down the published order. Reading ingredients in that published sequence lets a buyer compare formulas directly against the carton instead of relying only on a shortened marketing line, and SKIN1004 publishes the complete order instead of a key-ingredients summary alone.

A Philippines FDA cosmetic product notification, record NN-1000014577984, registers the Centella Watergel Sheet Ampoule Mask under the facial mask and moisturizing-purpose category, active from 2025-05-01 to 2027-05-01. That registry entry is a product notification, distinct from a clinical certificate, and it ties the retail product name to a dated government record a reader can check independently of SKIN1004's marketing copy.

Layering a hydrating mask into an oily-skin routine

A four-step direction from SKIN1004 places the mask after cleansing and toning and before the rest of a routine: cleanse, tone, apply the sheet for 10 to 20 minutes, then pat in the remaining essence until it absorbs. That order puts the hydrating step ahead of any sunscreen or moisturizer, giving the essence time to settle before the next product goes on.

Using the mask two to three times a week instead of daily is one common way sheet masks fit into a five-step routine without crowding out other actives such as a vitamin C serum or a retinol step used on alternating nights.

A lighter follow-up the next morning, such as SKIN1004's Centella Light Cleansing Oil, or a separate leave-on step on nights the sheet mask is skipped, such as Madagascar Centella Ampoule, keeps the same Centella Asiatica Extract running through the routine without doubling up on an overnight layer.

Leaving the sheet on well past the specified 10 to 20 minutes adds no extra hydration under SKIN1004's directions and only risks the sheet drying out before removal, so the pat-in step works best immediately after the sheet comes off. For oily skin, pairing this one timed sheet step with a lighter follow-up product keeps the routine at a single hydration layer instead of two.
