The Japanese manicure is an ancient, ritualistic nail care technique, dating back 400 years and often called “P.Shine” after the company popularizing it. Its primary goal is to improve nail health, leaving a natural pearlescent finish without polish. The process involves massaging nutrients like vitamins, keratin, and oils into the nail plate, followed by buffing with mineral powder for a lasting sheen. No metal tools or solvents are used, making it gentle on nails, ideal for damaged or brittle nails. The treatment lasts around two weeks and takes about 30 minutes.
