Lifeline Skin Care features concentrated peptides, amino acids, and enzymes from human non-embryonic stem cells. The stem cells are not synthetic, and they’re not derived from apples, melons, or any other plant-based material. Lifeline uniquely uses the same human stem cells that are active early in life to create new, young skin.These stem cell extracts help replace aged, damaged skin cells with new, healthy skin cells. We haven’t seen clinical studies to support or prove that human skin responds or relates to plant stem cells
