The 20-year-old met a dermatologist, who took blood from her arm and had it filtered through a special machine, before adding it to a custom product."I use a lotion from one dermatologist, who came and took blood from my arm," Baldwin told Look magazine.
"It was spun in this machine that separated the blood cells, then they created a cream just for me. I feel like that is pretty peculiar," she added.
Asked what she would do if she woke up with a spot the day before a show, Baldwin said: "I'm so psycho about my skin. First, I'd freak out, like, 'Did that really happen?' I take good care of my skin, so it doesn't usually happen. I have medicines from dermatologists I can use, but you have to be patient."
