 I loved working with Katie. I wish I had before pictures of my skin (I was way too embarrassed to take any back then) but oh my god. I feel like a completely new woman. I had horrible cystic acne on my jaw line for as long as I can remember and had seen multiple dermatologists about it. I went on and off spiro, birth control and accutane for years and sometimes it would get better but it would always come back. Im so happy I found Holistico. She gave me my confidence back! I don’t cry looking in the mirror any longer, there is hardly anything there anymore eeeep.

I have worked with Katie for almost 4 months now and I have noticed drastic difference in my skin. I had perfect skin before birth control and Katie help me get it back. I’m beyond thankful. There is no more hyperpigmentation any longer and no active pimples. I wasted so much money on skincare before her and tried everything under the sun to get it gone. Im so happy she achieved what I wanted in a holistic way and truly fixed all the damage birth control did to my skin. She is well worth it, trust your body!!

Today I have finished 10 weeks working with Katie and here is what I have noticed:

  1. Eczema was entirely gone within the first two weeks

  2. Redness in my face has decreased but still working on it

  3. I feel a lot more confident now and don’t need to wear makeup

  4. I no longer get massive whiteheads on my forehead or little blackheads on my cheeks

  5. I am not nearly as bloated or gassy as what I used to be (I think I had SIBO and she got rid of it)

  6. My periods are way more manageable
