CND RescueRXx is a daily keratin treatment for natural nails that have become weak, splitting, or peeling — it's an oil-based repair treatment, not a polish, base coat, or cuticle remover. Hydrolyzed keratin protein is the core active, carried into the nail by jojoba and sweet almond oils that also condition the surrounding skin as the keratin bonds to the nail plate. In CND's own clinical testing — 34 women using the product twice daily for four weeks — 80% of participants noticed improvement and fewer white spots within the first week, and by week four, 80% saw less peeling and 73% saw less splitting.
It's applied directly to bare, natural nails rather than over polish or enhancements, massaged into the nail plate, free edge, and cuticle. Because keratin treatments work cumulatively, CND recommends twice-daily use for at least four weeks rather than a single application. The product is sold to general consumers as well as through professional channels, making it a fit for anyone managing weak or brittle nails between manicures, or nursing nails back to health after removing gel or acrylic enhancements.
