I am brand-loyal.
I try to buy organic and paba-free and high fiber, etc. but sometimes I just stick with the brand, no matter what.
In the case of Yes to Carrots, however, I get something I like + something that doesn't have whatever evils are in facial creams. The product I get, C Through the Night, is more expensive than almost anything else I buy for my skin care regimine. But it smells nice, doesn't make me sneeze, and has a lovely texture. Plus, when my husband gets in bed he can ask me, "Did you say Yes to Carrots?" and I can say, "Why, I sure did!".
Have I noticed a difference in my face? Well, I do get compliments on my skin a lot. Though I still struggle with seborhheicceia dermatoititsiscis, the unspellable disease that I have, there does seem to be a nice even tone most days.
