vt Cosmetics One Mask
VT Cosmetics' All-in-One 3-Step Mask packets pack a serum or ampoule step, a sheet mask, and a finishing cream into a single-use kit, sold as Cica Letty-A, Reedle Shot, Cica Reti-A, Cica Collagen, and Vita-Lite variants, plus a 4-piece set that bundles several in one box. Alongside them sit the brand's everyday 30-sheet mask boxes, Cica Reti-A, Cica Collagen, and Cica Daily Soothing, for regular rotation rather than a one-off treatment. Twelve products are in stock, covering both the occasional intensive treatment and the daily sheet mask habit.

VT Cosmetics One Mask: 3-step kits vs. everyday sheet masks
VT Cosmetics splits its mask lineup two ways: All-in-One 3-Step Mask packets built for an occasional intensive session, and 30-sheet boxes meant for regular rotation. Both sides share the same Cica-forward formulas, so picking between them mostly comes down to how often you plan to use one.
What's actually in a 3-Step Mask packet
Each All-in-One packet bundles three separate steps that would normally be three products: a concentrated serum or ampoule, a sheet mask soaked in essence, and a finishing cream. They're single-use and self-contained, built for a night when you want a full treatment without assembling your own routine from separate bottles.
What makes Reedle Shot different
Reedle Shot is VT's microneedle-inspired serum step, formulated to feel like it's delivering ingredients deeper than a standard essence, without an actual needle. It comes in the same 3-step packet format as the other variants, and also as its own multi-piece set (15g, 15g, 25g) for people who want more of that specific step on hand.
Cica Letty-A, Reti-A, Collagen, and Vita-Lite: which to pick
Cica Letty-A and Cica Reti-A both lean on retinal-adjacent ingredients for renewal and texture, with Reti-A being the more established version in the sheet-mask line too. Cica Collagen focuses on firmness and soothing rather than exfoliation. Vita-Lite is the brightening option, built around vitamin-style actives for dullness rather than fine lines.
3-step packet vs. the 30-sheet mask box
The single 3-step packets are for an occasional, more involved treatment night. The 30-sheet boxes, Cica Reti-A Mask, VT Cica Collagen Mask, and Cica Daily Soothing Mask, are plain sheet masks meant for regular use, several times a week, without the ampoule or cream steps included. If you want a nightly habit rather than a monthly treatment, start with a sheet box.
How to use a 3-step packet
Apply the serum or ampoule step first on cleansed skin, follow with the sheet mask for the recommended time, then remove it and pat in the finishing cream as the last step. There's no need to add a separate moisturizer afterward since the cream step is already built in.
Trying more than one variant with the 4-piece set
The All-in-One 3-Step Mask 4-Piece Set bundles several variants in one box, a practical way to try Letty-A, Reedle Shot, Reti-A, or Collagen without committing to a full box of just one. Once you know which formula your skin responds to best, buying that variant on its own works out cheaper per use.
Who this collection suits
The 3-step kits suit anyone who wants an occasional at-home facial without buying three separate products. The 30-sheet boxes suit people who already use sheet masks regularly and want a Cica-forward option in daily rotation instead of a once-in-a-while treatment.

FAQ
Frequently asked questions
What's included in an All-in-One 3-Step Mask packet?
Each packet has three steps in one: a serum or ampoule, a sheet mask, and a finishing cream, applied in that order. It's built to stand in for a full treatment routine in a single-use packet.
What makes Reedle Shot different from the other Cica variants?
Reedle Shot is VT's microneedle-inspired serum step, aimed at feeling like deeper ingredient delivery without an actual needle. Cica Letty-A, Reti-A, Collagen, and Vita-Lite instead focus on renewal, firmness, or brightening.
Should I buy a 3-step packet or one of the 30-sheet mask boxes?
Pick a 3-step packet for an occasional, more intensive treatment night. Pick a 30-sheet box, like Cica Reti-A Mask or Cica Daily Soothing Mask, if you want a plain sheet mask for regular use several times a week.
In what order do I use the serum, sheet, and cream steps?
Apply the serum or ampoule first on cleansed skin, leave the sheet mask on for the recommended time, then remove it and pat in the finishing cream. No extra moisturizer is needed afterward since the cream step is already included.
Is the 4-Piece Set a good way to try different variants?
Yes, it bundles several 3-Step Mask variants in one box, useful for testing which formula, Letty-A, Reedle Shot, Reti-A, or Collagen, suits your skin before buying a full box of just one.
