## How it works

Methyl Diisopropyl Propionamide is named on the ingredient panel on this sheet mask. A synthetic cooling agent that gives the cool feeling of menthol without the mint smell. It is used where a formula wants the sensation but not the scent. On this panel it sits alongside Adenosine, Laminaria Japonica Extract and Eclipta Prostrata Leaf Extract. Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated.

## How to use

1. Use it as the weekly treatment, two to three times a week, for 15 to 20 minutes, giving it a moment to settle before the next step.

## FAQ

### When in a routine should I use this sheet mask?

Use it as the weekly treatment, two to three times a week, for 15 to 20 minutes. Placing a sheet mask out of order is the most common reason a Korean routine feels like it is not working, so keep this one at its own step rather than doubling it up with a product built for a different stage. Give it a few weeks at that placement before judging the result.

### Is this the same formula sold in Korea, or a US version?

This is sourced for the Korean market rather than reformulated for US shelves. Numbuzin sells a separate reformulation on some US shelves, and this listing is not that version. The Korean-market batch coding and packaging travel with it, which is the detail worth checking against the box on arrival.

### Where does this formula come from?

It comes from the Korean-market catalog rather than a US-shelf reformulation, and the packaging carries the same Korean-market batch coding a shopper would find on the box in Korea. That sourcing is checked on this row before the page is written, not assumed from the product name. It is the detail worth checking against the box on arrival.

### What does Panthenol do in this formula?

Panthenol is pro-vitamin B5, a conditioning agent Korean formulas lean on to keep the surface feeling soft rather than tight. It has a long track record in Korean skincare as a mild, everyday conditioning agent that layers cleanly under the rest of a routine. It sits at its own position on this product's own ingredient list rather than being assumed from the product name.

### What does Methyl Diisopropyl Propionamide do in this formula?

A synthetic cooling agent that gives the cool feeling of menthol without the mint smell. It is used where a formula wants the sensation but not the scent. It is named on this product's own ingredient panel.
