I am 37 years old and in the last couple of years I'm noticing a change in my skin. I'm much drier and I've seemed to have developed rosacea. I denied it for the longest time. It wasn't until I used Malibu C Zinc C Serum and Sensitive Skin Moisturizer that I noticed a difference in the redness of my face. My skin is looking normal for the first time in years! I don't have the heat like I used to either. I will continue to use Malibu C products because they actually work.
