Biossance Squalane and Copper Peptide Rapid Plumping Serum. Brand new! Never used! I literally just bought it in June 2023. I'm a sucker for skincare and very influenced by social media ads and trendy ingredients- when I kept hearing about copper peptides I couldn't help myself, but I'm too worried about deviating from my normal routine and KNOW I'll never use it. I'm trying to pare down my skincare collection bc I buy so much that I never use.
