Obagi Retinol + PHA Refining Night Cream is an overnight treatment designed to help refine skin texture and tone while improving the appearance of common skin concerns. Suitable for normal-to-oily, normal-to-dry, and combination skin types, this dermatologist-tested formula targets skin discoloration, uneven skin texture, and fine lines and wrinkles. Working throughout the night, the cream helps promote a visibly resurfaced, smoother, clearer, and more even-looking complexion, with visible improvements in as little as four weeks. The formula combines Entrapped Retinol with Polyhydroxy Acid (Gluconolactone) to support skin renewal and surface refinement. Entrapped Retinol utilizes slow-release technology for optimized delivery into deeper layers of the skin, helping encourage skin cell turnover. Polyhydroxy Acid provides gentle yet effective exfoliation on the skin's surface, helping improve texture and promote a smoother appearance. Together, these ingredients help renew and enhance the overall appearance of the complexion. The night cream is also formulated with nourishing ingredients that help maintain hydration while supporting skin comfort. Squalane helps improve hydration and texture while supporting a healthy skin barrier by mimicking the skin's natural sebum to help prevent moisture loss. Glycerin, a powerful humectant, helps support hydration and the skin's moisture barrier. Hydrogenated Lecithin helps maintain hydration by closely mimicking the natural lipids found in the skin, while Shea Butter provides rich moisturization and helps soften the skin. Clinical testing demonstrated visible improvements in skin appearance. Results showed a 29% improvement in skin smoothness and a 10% improvement in skin tone evenness. Consumer perception results revealed that 90% of participants noticed improved smoothness and reduced appearance of blemishes in four weeks, while 87% reported more even-looking skin tone and 80% noticed softened fine lines after eight weeks.
