Frequently Asked Questions

What does the Defining Serum do?

It helps visibly sculpt and redefine the look of the jawline and neck, especially where there’s sagging or heaviness.

How is this different from the Redensifying Serum?

Defining targets firmness and contour for heavy, sagging necks. Redensifying plumps thin, crepey skin and improves texture and brightness.

Can I use both serums?

Yes! Use one in the morning and one at night. You can also alternate daily.

Do I need to use the Leave-On Mask after?

Yes, we recommend layering the Neck Amour Leave-On Mask over the serum to lock in results and boost hydration.

    Just received it. I can't wait to use it for the first time. To be honest anything from SKINN is amazing. The product packaging is so beautiful.

    So far, so good!

    I’ve been using this product for about three weeks now and I really feel like it has minimized the crepiness of my neck and gives me more definition at the jawline. I’ll continue using it because I definitely see results at this point.

    Advanced Defining Serum

    I have used the Advanced Defining Serum for about two months and am very impressed with the way my skin looks and feels. I get compliments frequently about how beautiful my skin looks, which is something a lady enjoys hearing! I will continue to purchase Skinn products and look forward to a future of soft refreshed looking skin.
