Reviews of NuFace, a line of facial toning devices, are generally favorable. NuFace's signature product, the Trinity Facial toning device, has 4.4 out of 5 stars on Sephora.com, as of November 2015.
Positive reviews of NuFace claim the product improves lower cheek, jowl and jawline definition. It also reduces fine lines and wrinkles, including crow's feet and eye wrinkles. The few negative reviews assert that the product does not work. Negative reviewers also lament that the product is too expensive. Some of the reviews say the product is effective, but only to a degree. They say the effects disappear after 24 to 48 hours, so they have to keep using the product every day to get the desired result.
