Fantastic patches
Color: Collagen
These Biodance collagen peptide eye patches are truly fantastic! I have been consistently impressed by how revitalized and radiant my skin looks after every use—it feels genuinely nourished, hydrated, and leaves me with a healthy, natural glow. The results were so immediate and noticeable that I felt compelled to share the love, so I ended up purchasing several more sets to give as thoughtful self-care gifts for both my sister and my sister-in-law. I cannot recommend these highly enough to anyone looking for an effective addition to their Korean skincare routine!

Nice First Use, Feels Refreshing and Soothing!
Color: Collagen, Color: Collagen
I just started using the BIODANCE Collagen Peptide Eye Patches a couple of days ago, so this is an early impressions review. The packaging looks nice and the jar is easy to open and store. The patches are well soaked in serum and feel very cooling and refreshing when applied under the eyes. They stick well and don’t slide around, which makes them easy to wear while doing other things. So far, I like how hydrating they feel on my skin. They give an instant refreshed look right after use, especially in the morning. I haven’t used them long enough yet to see long-term results on fine lines or wrinkles, but I’m excited to continue using them and see how my skin improves over time. Overall, first impressions are positive and I think they’re a nice addition to a self-care routine.

Good Results, Slightly Dry Texture
Color: Collagen
I recently tried the BIODANCE Collagen Peptide Eye Patches and they worked pretty well for my under-eye area. The patches are packed with collagen peptides and feel nice and cooling when you first apply them. After 20–30 minutes, my skin looked a bit plumper and more hydrated, and the fine lines around my eyes appeared softer. The only downside is that they can be a little dry compared to some other eye patches I’ve used. Overall though, I noticed a visible difference in brightness and smoothness after consistent use for a few days. They’re convenient, easy to use, and do deliver on the anti-wrinkle and hydrating claims to a decent degree. If you don’t mind them being on the drier side, I’d recommend giving them a try — especially for targeting smile lines and tired-looking eyes.

Perfect plumper for under eyes.
Color: Collagen
I absolutely love the moisturizing effect these have under my eyes. My undereye skin appears plumper making the fine lines show less for at least 5 hours. The skin also feels much softer. These are absolutely a great value for the money. I will be buying these again. Perfect for a morning you wake up with puffy eyes and need to get put together quick because they made my eyes look amazingly rested and took all the puffiness away in 10 mins.
