Peptides are quite a controversial topic. Do they work? Are they safe? Personally, I'm a fan of peptides and I had to try Cell Fusion C Laser Rejuvenation Ampoule, but not because it's a serum full of peptides, but because this K-beauty brand is popular amongst professional estheticians. Cell Fusion C Laser Rejuvenation Ampoule is not only a moisturizing and rejuvenating serum, but it also has one interesting function which many people will love and it's related to hair.
