What the gurus are saying

This serum earns praise for its silky gel texture and how beautifully it hydrates and plumps the skin without feeling heavy or sticky. One creator finds it gentle and gives it a glow, though the copper peptide concentration is on the low side. Another notes the price is steep at nearly $70 for 50ml and questions whether the copper peptide amount is clinically effective, yet she has repurchased it twice because the texture performs so well, absorbs quickly, and leaves skin feeling smooth and bouncy, even in hot weather.

"The biosan copper peptide is a very very beautiful formula and it is non-irritating and it is absolutely gentle. This is a copper peptide serum because the concentration is a bit low but beautiful glow non greasy, doesn't have any kind of side effects. It is an absolutely beautiful formula. The formula is made with squalane so by default it is super super moisturizing. It is directly sunscreen you don't use a moisturizer, your skin is going to feel super hydrated."

"Biosan Squalane and Copper Peptide Rapid Plumping Serum, I have such mixed thoughts about this. On one hand it's really freaking expensive, it's almost $70 for 50ml of serum, and the amount of copper peptide, like is it an effective amount, is it a proven clinical amount? Probably not. But on the other hand, this is the second bottle of this that I've emptied. I really do enjoy using it. It's a pleasure to use."
