Great Serum

Steven SarnowskiJune 3, 2025✓ Verified purchase

I'm genuinely impressed with what this serum can do, especially if you're looking for a little extra oomph and better skin texture around your jawline. Right from the first use, this serum just feels good—it's super light, soaks in fast, and doesn't have any weird smells, which makes it a breeze to use both morning and night. I definitely noticed my skin feeling firmer and a bit less puffy in the mornings, which made my jawline look subtly more defined. My skin has been feeling incredibly soft, smooth, and hydrated. It truly gave my whole complexion a healthy, happy glow. I have been using it for about 3 weeks now and definitely see results. Will continue to purchase this item. Read more

Shapeshifter seems to work.

April SandersJanuary 4, 2026✓ Verified purchase

I am on my second bottle of this and been using it for a few months. I feel like it’s working. My jaw line and neck are more defined but I also use a Nuface device so it’s probably a combination of the two things. I first saw this on The Today show which is why o purchased it. Read more

Great product!

SaraApril 30, 2025✓ Verified purchase

As I’m getting older I’ve noticed some sagging in my lower jawline. This product is the first one I’ve tried to help with this issue because the reviews are so good. I really like the packaging and the high end feel to the bottle. It goes on smoothly and absorbs quickly without feeling sticky or smelling weird, which I appreciate. I have had some noticeable results so far and feel like with more use I will be very happy with the outcome! Read more

Expensive and doesn't do anything

Doesn't feel like it did anything more than acting as a humectant, and its very expensive.... Read more

Noticeable Results, Easy to Use

Nicole C.April 21, 2025✓ Verified purchase

Really impressed with this serum! After using it for a bit, I noticed my jawline looked more defined and my skin felt smoother. I am extremely sensitive to smells and happy to report there is no overwhelming scent. It’s easy to use, absorbs well, and feels great on the skin. Definitely a new staple in my routine! Read more

Don’t believe the hype

CrystalFebruary 11, 2026✓ Verified purchase

I was unimpressed with this serum. The product worked well, but I didn’t see any noticeable difference or improvement. Considering the price of the product I was disappointed and felt that I could get better results with other products. I’m currently using an Elemis brand neck and décolleté balm which I prefer. Im always looking to try new products, but this was sadly a miss for me. Read more
