Pros: I decided to try the ANUA PDRN Collagen Melting Patch after seeing it all over my social media feed during Prime Day, and the melting effect really is fun to watch in person. Once I sprayed my neck with the ANUA PDRN Mist first, the pink film disappeared into a clear layer almost instantly, and after a second spray to loosen the white top layer, my neck was left with that thin, barely there residue everyone talks about in the videos. The ANUA patches felt gentle going on and the whole process, once I understood the two spray steps, was quick and easy to fit into an evening routine. I followed up with a heavier cream afterward and my skin felt soft and hydrated for the rest of the night. As an occasional treat for my neck, this was a satisfying little skincare ritual and I can see why it has gotten so much attention online.Cons: My biggest hesitation with the ANUA PDRN Collagen Melting Patch is the price relative to what you get, since a box only includes four patches and that is not something I could work into a daily habit at full price. The application process is also easy to get wrong if you have not watched a demo first, since the instructions do not make it obvious that you need to spray twice, once to melt the pink layer and again to loosen the white layer underneath, and I noticed several other reviewers ran into the same confusion. My neck also felt a bit itchy after the product absorbed, which had me reaching for a soothing cream to calm things down. After one use I did not notice any visible plumping or softening of my neck lines, and I suspect real results would require consistent daily or near daily use, which brings the cost consideration right back into play.
