What it is: A lightweight, oil-free, antiaging treatment that improves visible signs of aging. What it is formulated to do: Jack Black’s Line Smoother Oil-Free Moisturizer improves texture and helps even out minor skin discolorations, leaving skin smoother and younger-looking. Natural fruit acids—eight percent glycolic acid, a natural acid found in sugar cane—help minimize the appearance of fine lines and wrinkles by sloughing off the top layer of dead skin cells, revealing softer skin hidden beneath the surface. The quick-absorbing formula provides intense yet lightweight moisturization with no lingering greasy feel. What else you need to know: This product is dermatologist tested and free of alcohol, fragrance, and colorants.
