This was the 2nd time ordering this peptide, it is wonderful for hydrating nails and cuticles.
I would love to know how great this products potential is…however, I just received it and cannot get it out of the bottle. I will probably follow suit of the other reviewer and cut the top off with pliers. Has anyone at Londowtown tried to use this? It’s impossible!
Thank you for sharing your feedback with us. Your experience is very important to us, and we want to make sure you’re able to use the Peptide Serum Concentrate as intended. The bottle is designed to dispense a small, controlled amount by gently pressing the soft base at the bottom, and we strongly recommend holding off on altering the packaging so we can first review the specific bottle with you. We’d really like the opportunity to take a closer look and help make this right, so our Customer Service team will reach out directly to make sure you feel fully supported.
Smells great, moisturizes nails and cuticles, easy to apply!
has made no difference to my nails
This serum does improve the cuticles and the nails. I use it at nite 3x week. Improved the appearance of my nails by providing a smoother and rosier looking natural nail. It does moisturize the cuticles and keeps the hangnails at bay. It also has a nice scent to it.
I am pleased with my serum and happy that I got it.
