Read the name and you would bet money this mask is built around peptides. Read the ingredient list and there isn't a single one. "Peptaronic" is a portmanteau doing some creative lifting, and the actual formula is a hyaluronic-acid mask wearing a more impressive-sounding label. Normally that kind of gap is where a review turns into a takedown. Here it doesn't, because once you stop expecting peptides and judge the sheet on what's actually in it, it's a quietly excellent hydrator that happens to cost a little over a dollar a use.
What SNP actually loaded into the essence is three different forms of hyaluronic acid: standard sodium hyaluronate, hydrolyzed hyaluronic acid, and sodium acetylated hyaluronate. The reason that matters is molecular size. The larger sodium hyaluronate sits on the surface and holds water like a sponge, while the smaller hydrolyzed fragments slip into the upper layers and pull moisture downward. Stacking the sizes is why a good triple-HA mask plumps more convincingly than a cheap one running on a single grade, and it's the most legitimate part of this formula. After the twenty-minute soak, skin genuinely looks bouncier and more light-reflective, the fine crepey texture that dehydration produces softens, and makeup goes on better the next morning.
The second thing SNP did right is build a calming base underneath the humectants. Panthenol sits high on the list, and pro-vitamin B5 is one of the most dependable soothing humectants going. Then there's a centella double act, whole-leaf cica extract plus purified madecassoside, the single most-studied fraction of the plant, alongside allantoin and licorice root. Licorice brings glabridin and dipotassium glycyrrhizate, both of which quiet redness, and there's a whole supporting cast of antioxidant botanicals, green tea, ginger, schizandra berry, that read more like seasoning than headline actives but do no harm. The practical upshot is a mask you can use after a sunny day, a long flight, or an over-enthusiastic exfoliation session and trust it to settle skin down rather than stir it up.
Texture-wise this is a classic Korean ampoule sheet: a thick, faintly viscous essence that saturates the cotton without running down your neck, and a sheet that actually fits a human face reasonably well. It goes on cool, sits comfortably with no tingle, and leaves a light tacky film on removal that you press in rather than rinse. Within about five minutes the tackiness resolves into a soft dewy finish. There's enough leftover essence in each pouch to take down to your neck and the backs of your hands, which is part of why the value math works out so well.
So what holds it back? Two honest things. The first is fragrance, listed plainly on the INCI. For most people it's a pleasant, fast-fading herbal-floral note and a non-issue, but if your skin reacts to added fragrance this is the line item to weigh, and no amount of soothing cica fully cancels a fragrance you're sensitized to. Patch test before you commit to a box of ten. The second is the name itself, which sets an expectation the formula can't meet. If you came specifically for a firming peptide treatment, this is the wrong product and you'll feel short-changed. If you came for hydration, you'll feel like you overpaid by nothing.
Value is where it pulls clearly ahead. A ten-pack runs in the low-to-mid teens, which works out to a little over a dollar per generously soaked sheet. That's drugstore territory for a mask that performs like something pricier, and it's cheap enough to use as a routine midweek hydration step rather than a special-occasion treat. The single-use foil packaging is the usual environmental wince that comes with sheet masks, and there's no getting around it here.
A note on getting the most from it: the format itself is part of the value. A sheet mask's whole advantage is occlusion, the cotton layer traps the essence against your skin and slows evaporation, which is why twenty minutes under a sheet drives more humectant into the surface than the same essence simply patted on and left to air-dry. That also means timing matters, pull it before the sheet starts to dry and reverse the process. Keep the unopened pouches in the fridge through summer if you like; the cool sheet does nothing extra for the formula but turns a routine step into a genuinely pleasant few minutes, and de-puffs a tired face faster than a room-temperature one. It's a small ritual, but it's the kind people actually keep up.
Where this lands is a confident recommendation with an asterisk. As an affordable, widely available, genuinely effective hydrating and soothing mask, it's one of the easier K-beauty staples to keep in a drawer, and the triple-HA-plus-cica combination is a smarter build than the price suggests. Just buy it for what it is, a hydration mask, and ignore what the name is trying to sell you. Skip it only if added fragrance is a dealbreaker for your skin, or if you specifically need peptides, in which case you should be shopping a different aisle entirely.
