The "how to use" on this product shows it being applied after Vitamin C and E ferulic; however, I was just advised NOT to use Tripeptide Neck Repair with Vitamin C because it is a retinol. I was told by the chat person to wait 30 minutes before using Neck Repair, if I'm also using Vitamin C on my neck. So, this is somewhat misleading.

I have tried many necks creams out there (Strivectin, Nectifirm, Sub D, etc), and this is the only one that has helped me. I have struggled with crepiness that just exacerbated my "turkey neck", and I am amazed with the improvement. I still don't have a perfect jawline of course, it's not a miracle, but it has made a significant difference. I am super pleased!

I had been wanting to try something to improve and smooth my necklines. I asked my dermatologist what she used and she recommended this product. I can see improvement and am now a huge fan!

Feels like heaven! All I use- Skinceuticals has improved my 56 year old face exponentially!! Thank you!

I am a long time customer of Skinceuticals and as they evolve product, so do I. This product is new to my evening regimen. At age 62, who loves the sun, I see this product is helping my neck and this is my second bottle.
