Fast service!!
Goes on nice and makes my nails and cuticles look and feel great. I used it daily in the morning and at night and I have seen a huge difference in m6 nails and my cuticles.
This is the biggest disappointment I have ever experienced from Londontown. My nails are splitting and I was hoping this would help. First it’s hard to open, second it didn’t seem to be full and third it just doesn’t work. It’s not even that good as a moisturizer for the nails. SKIP IT!
Thank you for sharing this experience with us. We take feedback like this seriously, and we’d love to better understand what you’re experiencing with Peptide Serum Concentrate. Our Customer Service team will reach out directly to learn more about your routine and the specific product you received so we can take a closer look and help make sure the rest of your experience with the serum is a positive one.
Love LondonTown priducts! They never disappoint!
I find that dispensing the product with the cap on doesn’t work. I have to remove the cap but then it dispenses too much so I have to share it with other nails. Disappointing. I’m not sure yet if it’s a good product or not.
Thank you for sharing this feedback. Peptide Serum Concentrate is designed to be used with the cap removed, then with a gentle press on the soft bottom to release a small, controlled amount through the precision tip. Since you’re finding the dispensing amount difficult to control, our Customer Service team will reach out directly to take a closer look at your specific bottle and help find a solution so you can enjoy a smooth, easy application.
