Be careful using these products. I have sensitive skin and although their products says it’s ok for sensitive skin, my skin peeled and needed antibiotics. I followed the directions perfectly. The products causes inflammation requiring me to use ice packs to calm my skin. When I used the system, Day 1, nothing wrong; Day 2, inflammation; Day 3, inflammation didn’t go away and I had used the nose strips on Day 2 which caused infection (peeling skin). Between the 2, I had to take antibiotics. Be careful.
