Not purposely, I just use stuff that's good for my skin. Vitamin E, natural products heavy in natural oils [jojoba, olive, avocado, etc] or butters [cocoa, shea, mango]. And a good sunscreen will go a long way. As far as preventing acne, witch hazel and willow bark. I'm 22.
There are some new methods of anti-aging treatment nowadays. Have you heard of them? I now that stem cell therapy can really help with different diseases, even this one. You can get some info on it from http://uctclinic.com/ My friend recommended it to me. He says it is a very good and reliable clinic
No and I'm 29. I have a young face. My grandmother once told me if you have had bad acne as a teenager and into your twenties, you won't get wrinkles. I think she's right because when she died at 80 years old, she had no wrinkles at all. I mean, there were some creases in her face, but my mom's mom had more wrinkles then her.
