The three step process did not work for me, it caused me to break out more because it dried up my skin. It made my skin really flaky and red so I stopped using it immediately and got my money back. Im 16 and I think I tried it at 14. I have sensitive skin so that might be the reason.
Then after that, on my 16th birthday I got the Neutron Advanced Solutions kit. Ive never had a problem with neutrogena and I love their products. It worked really well!! it really got rid of a lot of my acne in just a few weeks, I was amazed and still am by how much better my skin looks. I really would recommend he Neutrogena kit to anyone struggling wtih acne becase its alot less harsh on your skin and doesnt try it out and will really clear up your skin.
