Hi there,
I have tried using the EGF repair ampule and C- niacin toning ampoule, at different times and both caused irritation and dryness to my skin. I first tried the EGF ampule, for the first two days it worked fine, but I started to notice my face becoming dry and tight after several days. I thought that might just be a phase and continued but my skin only worsened with rough patches on my cheeks and chin. I stopped using it and waited a while until I tried the C-niacin toning ampoule which gave me the same reaction. I have also been using the hyaluronic acid toner and green tea lotion which works great. I really wanted the ampoules to work, sadly not for me. Any suggestions on what I can do? Thanks!
