Started using The Ordinary Copper peptide

So, I started using The ordinary Copper Peptide. In the first use itself I can see my skin looks fresh. Not any drastic change but I used it in the night time and next morning I felt my skin was looking better. Did anyone here tried this product? How do you feel about it? How many days it takes to see results? I use it only in night followed by a moisturizer only. How do you apply it? Would like to know more about this product.

I liked how my skin looks next day morning. While applying I feel little tingling. Is it normal?
