  • PTR with collegian
Loving this product so far, face appears younger after wearing it only one day. Under Eye circles have diminished, lines decreasing. Very pleased. Thank you PTR again! Moisturizes my skin, it is effective, the scent is mild, my skin is soft and the value for the money seems ok as long as it does what it says! ... show more

  • This will always be my go to!
I can't praise Peter Thomas Roth enough! His products are truly phenomenal. I absolutely love this collagen; it's the only one I'll use. It's been a bit harder to find lately, which makes me a little anxious because this is my holy grail of collagen. I frequently receive compliments from people who can't believe I'm 39—they always think I'm in my 20s! Thanks, Peter Thomas Roth. ... show more

  • Love this.
I have only four stars because it doesn’t actually firm, but my skin does feel softer and smoother.

  • Don’t do it .
I have had this product for about a month and it is literally the biggest waste of money I’ve had . I’m 29. I take really good care of my skin and always have . This product has literally made zero difference. The texture of it was really thick and you had to put on a lot of it to lather the entire face and neck … After a month it already ran out. Waste of money . ... show more

  • Filmy Residue
I received this about a week ago so it is too early to tell if it does what it claims to do. If I see results I’ll come back and update this review. My initial impression is that it feels nice going onto my face but it leaves a film. This morning I put it on 30 minutes before applying my moisturizer and the moisturizer beaded up on my face. Maybe because of the SPF? Once i got a handle on that my primer and foundation went on fine but it was a pain. ... show more

  • Did not deliver as promised
I love this brand and have other products that work well. I have been using the collagen serum for three weeks and see no results.
