What Nail Hardener Does Kim Ji-won Use? Her Alessandro Pouch Pick
Kim Ji-won showed an Alessandro Nail Hardener in her Vogue Korea beauty-pouch video. She said she applies it to bare nails. If you are trying to identify the bottle rather than copy a colored manicure, this is a nail-care product. The video confirms the brand and product category, but does not establish an exact current product code.
What Kim Ji-won actually showed
The bottle appears around 2:25 in Vogue Korea’s BEAUTY ESSENTIALS video published on October 7, 2024. The on-screen label reads ALESSANDRO Nail Hardener. Kim describes it as a nail-strengthening product and says she has been applying it to her natural, unpainted nails.
She says she started using it after hearing that it helps make nails stronger. The clip does not include before-and-after results or a measured treatment period. Her explanation identifies an item in her pouch; it is not evidence that every user will get the same result. The video also discloses Bvlgari Parfums product sponsorship, so the whole episode should not be described as entirely unsponsored.

Is it the current Express Nail Hardener?
Alessandro’s current official range includes Express Nail Hardener, product 46-005, 10 ml. The brand describes a clear, glossy finish. It is a useful official reference for understanding the product category, but the 2024 video does not confirm that this current listing is the exact formula or version in Kim’s pouch.
That distinction matters when shopping. A retailer may use her name in a listing, but the words “Kim Ji-won’s nail hardener” are not a product code. Compare the full product name and capacity, and check the instructions printed on the bottle you are actually buying.

How does the current Express version work?
The official Express product directions describe removing existing nail polish, preparing the nail surface and applying two coats twice a week. Each coat should dry for about two minutes, with the process repeated during the second week. These are directions for the currently listed Express version, not a routine Kim demonstrates in her video.
The manufacturer says to apply it only to the nail surface and not to use it immediately after removing artificial nails. Keep the instructions with the product, especially if you buy a different Alessandro hardener: a similar name does not mean that the application schedule is identical.
Clear nail care, rather than a color shade
If you arrived here searching for Kim Ji-won’s nail polish color, this particular video segment is about care for bare nails. It does not identify a colored manicure shade. The current Express listing describes a transparent, glossy finish, so it should not be compared with an opaque color solely because both come in small nail-product bottles.
The video does not show how she layers the hardener with other polish, how often she removes it or how long she has used that exact bottle. For those details, the product’s own directions are more useful than filling in gaps in her short explanation.
Price and availability
On October 22, 2026, the German official storefront displayed €12.99 for Express Nail Hardener 10 ml. That is a dated regional price, not a worldwide price or an estimate of the cost of Kim’s 2024 bottle. Shipping destination, local taxes and retailer availability can change the amount you pay.
For an exact-match search, start with the original video. For a current purchase, use the official product page to check the full name, size and directions. Keeping those two steps separate avoids confusing an identified celebrity item with a later product that merely looks similar.
