Snail mucin does not naturally contain copper peptides. Copper peptides are a specific type of peptide that contain copper ions. However, snail mucin does contain other beneficial compounds such as hyaluronic acid, glycolic acid, and various growth factors. These components can contribute to the overall moisturizing, anti-aging, and skin-repairing properties of snail mucin-based skincare products. If you are specifically looking for the benefits of copper peptides, you may need to explore other skincare products that contain this ingredient.
