I like to use this right before my foundation to give me a smooth cover, without using other primers that have bad ingredients in them. I have not experienced and breakouts of any issues while using this serum.
My husband loves the product, I have noticed the most changes with his skin while using the serum. He used to have redness in his skin tone, and larger pores. Now the pores are smooth enough you can't see them, and his skin tone is even and a nice bright color. I noticed dramatic changes in 1 month on him.
I was glad to receive a bottle of this from the company to test out and purchase at an extreme discount, or free. This is my honest opinion of the product.
