Dr. Elizabeth K. Hale, a New York University dermatologist, wholly endorsed the Lifeline® stem cell skin rejuvenating line of products during an interview with Access Hollywood.  Dr. Hale understands that the role of human stem cells is to renew damaged skin tissue.  The extracts from non-embryonic stem cells target skin that is damaged from sun exposure and/or aging and then gets to work on repairing and renewing wrinkles, sagging, and facial tone.
