Great information, thank you for sharing! I had no idea about hyaluronic acid not actually penetrating the skin -- I'll get that edited right away. And I think I was turned off witch hazel because I used it when I was younger and it was too astringent for me... but I was probably using one that contained alcohol. I actually wanted to try Skinmiso's Pore Corset but was turned off because it contained witch hazel, so I'm excited to try it now. And I've never heard about a lower pH level making some treatments more effective, but it makes sense. But like you said, not something to do regularly.
I'm looking forward to your posts! I just checked out your blog and I'll be sure to follow you. Thank you again!
