My first purchase was the dermaplane tool and mini HA Serum. I have used the tool twice now and the serum for a few weeks. I was initially scared to dermaplane at home, but the tool was much easier to use than I expected. After the first two weeks, I added the TCA Face Peel and EGF Activating Serum to my new routine. So far I can see a noticeable change in skin tone and hydration. I am hoping with continued use I will see improvement with my hyperpigmentation as well. By starting with just the dermaplane tool and mini products I was able to test this line on my sensitive skin. I have been so happy with the results I have now invested in both the full size serum and full size peel. I am hooked and my skin feels amazing!
