I haven't heard of that but that blue light that I posted about a month or so ago really works...it just takes a few weeks to see results. You have to use it everyday for 15 (I did 30) minutes. In about 5 weeks you will see a big difference. After I stopped using it my face broke out again though. I was breastfeeding and stopped using it when I weaned since I was going to start medication for it. When you get pg, your skin will clear up I bet. Mine does and I have terrible acne. I think the website is
www.acnelamp.com or something like that. Good luck!
