I previously received a full size sample of the Luminizer Primer in a subscription box I purchased. (All companies should do such). It was my first experience with Dr Brandt and I used it till the last drop! Loving that sample so much, I came to the website to make my first purchase when the Pore Refiner Primer caught my eye. Since my first Dr Brandt primer experience was so great I thought I’d try it. It truly feels like silk! I love it even more than the Luminizer Primer. There is the slightest tint to it that affords this 50 year old the ability to wear just the primer alone. It does not feel heavy and pores as well as wrinkles seem to fill in and become less noticeable. I will be a returning Dr Brandt customer. I wonder what I should try next.
