Beauty is so many things... a big smile, a great outlook on life, a hot dress... and radiant, healthy beautiful skin!
I've seen a few of Dr. Amy Wechsler's youtube videos and read parts of her book online and I like what she has to say about skincare. She's one of the only dermatologists who also has a degree in psychology, so it's interesting to hear her studies on the connection between our brain and how we think and feel and our outer beauty and skin health. Her book is called The Mind-Beauty Connection.
