At age 30, skin cells start to become dormant,” explains Dr. Obagi. “You need to wake them up and encourage them to produce collagen and elastin. It’s important to keep those skin cells in the dermis functioning well to maintain a healthy, youthful appearance. Look for products that contain high concentrations of retinol—it’s the most effective ingredient for anti-aging.” Ossential Radical Night Repair Plus Skin Health program is formulated with 1.0% retinol—the highest over-the-counter level available. This unprecedented product line employs a prescription-strength time-release delivery system that increases penetration while reducing irritation, effectively minimizing the appearance of fine lines and wrinkles without inflaming skin. More advanced and robust than any other anti-aging product currently on the retail market, Radical Night Repair Plus stimulates cellular renewal and repair for optimal collagen production and improved elasticity.
