Sheet masks are a K-beauty staple, and they show up often in idol vlogs and backstage clips. The catch for most of us is consistency: a box of masks sits in a drawer for months. Round Lab's 28-Day Anti-Aging Mask Sheet Bundle is designed around that problem. Its pitch, in Round Lab's words, is "28 Days of Masking, One Box." Here is what is inside and one simple way to plan your four weeks.

What Round Lab says about it

According to Round Lab, the bundle gives you 28 masks, a full four weeks of nightly care, across four different formulas so you can choose the right one for whatever your skin seems to need that day. Based on Round Lab's product page as collected by KPOPORO, the mix is:

  • 10 × Soybean Panthenol Sheet Mask: presented as the everyday base, with black soybean and panthenol, aimed at nourishing and calming dry or sensitive skin.
  • 10 × Vita Niacinamide Dark Spot Serum Mask: aimed at a brighter, more even-looking complexion.
  • 4 × Camellia Deep Collagen Firming Gel Mask: a gel mask that, according to the brand, gives a firmer, bouncier-looking finish.
  • 4 × Camellia Deep Collagen V Lifting Gel Mask: shaped to fit the jawline and cheeks.

Round Lab says the masks are gentle enough for daily use and suitable for all skin types. The "anti-aging" name is Round Lab's own; the page does not present test results, and we have not tested the masks.

Where it fits in a routine

In the usual order of cleanse → toner → serum → cream → sunscreen, a sheet mask goes right after toner. Round Lab's directions are to apply the mask after cleansing and toning, leave it on for 15-20 minutes, remove it, pat in the remaining essence, and follow with moisturizer. Since the box is pitched as nightly care, the evening routine is the natural place for it.

A sample four-week calendar

  • Weekly base (5 nights): alternate Soybean Panthenol and Vita Niacinamide masks. Over four weeks that uses all 20 of them.
  • One "special" night per week: a Camellia Deep Collagen Firming Gel Mask, for example the night before a concert, fan meeting or photo-heavy day.
  • One more night per week: a Camellia V Lifting Gel Mask, which completes the 8 Camellia masks.

That adds up to 28 masks in 28 nights. If your skin feels overloaded, simply skip a night; nothing says the calendar must be exact.

Who it might suit

  • People who enjoy sheet masks but want a planned box that builds a habit.
  • Anyone curious about several Round Lab lines at once: Round Lab describes Soybean Panthenol as its barrier line, Vita Niacinamide as brightening and Camellia Collagen as firming.
  • Gift shoppers looking for a K-beauty set that lasts a full month.

What to check before you buy

  • Price: listed at $99.22 on Round Lab's US store at the time of writing, which works out to roughly $3.54 per mask. Check the current price on the brand page.
  • Shipping: confirm that Round Lab's US store ships to your country and check for shipping costs or import fees.
  • Patch test: even with products described as gentle, test each new formula on a small area before a full-face mask, especially with four different formulas in one box.
  • Storage: plan where 28 masks will live; a cool, dry spot is a sensible default.

Our take

This bundle is less about any single mask and more about structure: four weeks, four formulas, one box. If you like the idea of a masking calendar and want to sample three Round Lab lines, it is an easy way to do it. If you only mask now and then, a smaller pack may make more sense. Either way, check price and shipping first.
