I was recommended this product by a girlfriend and before purchasing the N45 Firming Peptide Duo I wanted to see if I liked the morning serum, N45 Firming Peptide Complex. It has become my favorite product. My face feels amazing! It’s hydrating, feels light on my skin, and my face feels tighter when I apply it. Although I am starting to see the signs of aging on my face I feel like I have the best secret weapon now, and I will definitely be investing in the N45 Duo next time. Cheers to aging gracefully, Celazome.
