Hyaluronic acid patches for knee support. Received in October 2025. Sheet-type hyaluronic acid patches for direct application to the knee. 6 patches ✖️ 1 bag. Approximately 6.6mg of hyaluronic acid per patch. Please be aware that counterfeit products of Hialoaid without lot numbers have recently been circulating. Also, it seems that Hialoaid purchased from the official website from around mid-April of this year has lot numbers on the back of the box starting with "K". We recommend trying the new Hialoaid. Brand new, unused. A copy of the Hialoaid usage instructions will be included (see photo 3). If you don't need it, please comment on the transaction screen. Instant purchase OK. No price reduction requests, please. Will be sent via standard mail. Please understand that it may take several days to arrive, especially if it includes weekends and holidays. For those who prefer anonymous shipping, I will accept it for an additional 50 yen for shipping costs, so please comment before purchasing. Because it's difficult to fit in the envelope, I will fold the long side of the Hialoaid by about 1cm. The product itself will not be folded, but please refrain from purchasing if you are concerned. Depending on sales on other sites, I may ship a product with a different lot number than the one in the photo, but I will ship Hialoaid that arrived at the same time or later than the lot in the photo, so please rest assured. I have a subscription, but my condition has improved and I don't use it every day, so I have a lot of it and am selling it. Would you like to try it? Please understand that this is a home-stored item. Thank you for viewing.
