What a huge difference in my skin. I have been using the Clairisonic and I just switch to Murad Resurgence (which I use at night) for about two weeks now and now my skin looks 15 years younger. I am 48 and I some thought I was 33 today, so I took a look in the mirror and I will be damned it is actually working. My skin has this glow and firm look like I did when I was in my mid 30's. My faith in skin care is renewed. I was starting to lose faith for awhile.
