Cosmetics Formulation Development

I want to know the difference between Quick-Coll® and Copper Peptide (GHK-Cu) >If used to stimulate collagen production Or reduce scars like acne holes, which one can do better? > Each substance is suitable for use with what formulation? > Can these two substances be used in the same formula? Thank you in advance

Hello Quick-Coll is the successor to Copper Peptide by using Copper Peptide connect to Lysine , Proline in order to achieve more efficiency, as a result, can expect more performance. Copper Peptide Normal, can be used together in the formula. but in case the formula is used Quick-Coll , the team thought that using Copper Peptide again, it will not be able to provide more efficiency.
