I've been using this along with the face wash and day cream for about a week. I'm noticing little pimples breaking out all around my face. I don't have overly sensitive skin and I'm wondering if a purging effect is supposed to occur or if I should just stop using this skincare line? Could it be the Shea butter in the skin cream?
- Asked by Katy

Smells too bad to use
Honeslty dont buy this. I tried to get past the smell but i just couldnt. I would literally smell it through out the whole day and also, its very sticky. Would not recommend or repurchase.

Again, as I'm finding with most of the products a little bit goes a long way. I've actually been using this only about 2 weeks now and I know I have seen some improvement in my lines and wrinkles on my face. Basically with the skin care as a whole including the eye cream, I'm seeing a difference in my skin.
