This Peter Thomas Roth peptide cream is packed with 21 peptides and neuropeptides to visibly reduce wrinkles and fine lines (a claim backed up by reviewers who have used it).

Experts previously told HuffPost that peptides are useful in skin care because they can “mimic the body’s natural proteins to stimulate cellular growth and promote overall cellular health,” according to dermatologist Dr. Corey L. Hartman. Dermatologist Dr. Anna Chacon also previously said that some peptides can penetrate the skin barrier to increase the production of collagen, which “can improve the skin’s elasticity and smooth fine lines, delivering noticeable anti-aging benefits.”

That’s not all, though — the cream also contains skin-nourishing ingredients like gamma proteins, cactus flower and squalane, all of which can help with mature skin concerns like firming, elasticity and dryness. According to the brand, 90% of users in a clinical study saw the appearance of their wrinkles decrease in just a week of use.

Reviewers are also shocked at the quickness with which this moisturizer gets to work; some noticed results in mere days.

“This is WELL worth the money spent,” one reviewer wrote. “I have been struggling with dry, flaky, itchy skin for MONTHS & trying everything I possibly could. Nothing would help, not even my prescription steroid cream. This turned my face around in 2 DAYS. It’s now super soft, hydrated, and has its bounce back. I cannot recommend it enough!”
