Hi Prudvi! Could you clarify why copper peptide should not be used in the same routine as Retinoids? I understand the need to streamline the guidance for the general user, but for those of us who are long term retinoid user with no sensitivity issues it will be good to understand the reasoning behind it (I.e whether it increases irritation, or it actually renders the copper peptide useless). I would imagine there are many experienced acid/retinoid users who use ascorbic acid in the AM and retinoid in the PM daily, thus having a hard time fitting copper peptide based on the general guidance per DECIEM website.
