I absolutely love and very much appreciate your videos! I'm 68 years old and for over 20 years, I've been making my own skin care. It started as a hobby, but now that I'm retired from a "real" job, I'm making my products for others, as well. By the way, using my own skin care has gotten me several compliments regarding my actual age versus the age I appear to others. The economy is such that I cannot afford costly courses, and so I've done, and continue to do, my own research, asking questions of professionals, and buying books on the subject of all kinds of ingredients. So, I just wanted to thank you for the information you do provide to those of us struggling to survive this economy!
