I've used 302 since 2005 when I was 50 years old. At the time I was struggling with acne scars, redness, oily skin, and breakouts. I had tried lots of skincare products, and I realized that was my problem - I was using too many things, all at one time. I actually stumbled upon 302 from a mention in a skin forum. I had never heard of it, didn't know much about it. I started researching it and their philosophy that less is best and to not use harsh acids was totally contrary to every other skincare line I was using at the time. I gave it a go, but I wanted to get some advice first. So I emailed the company. To my surprise, a real live person responded and it was the founder! He was genuinely interested in my problems and gave me advice on how to use the products. It was tough going in the beginning because my skin was so addicted to the products I had been using. But over time, my skin returned to normal, scars started to flatten out. I was amazed at how well these products worked and that it was sustainable and helped my skin return to its natural state. All without a rigid regimen or over-the-top expense. At that point, I became a customer for life and I have not strayed from 302 since. I trust the company, the formulations, and their knowledge of how the skin works. I'm now 68 and have no intention of ever using anything else. Thanks 302 for 18 years of skin bliss!
