Specially formulated together with an allergy specialist, Dr. Kumiko Mukoda who is based in Kyoto, the K+CL Skin Clear Soap helps to slow down aging. It promotes cell renewal for younger-looking skin while locking in moisture. S-Labo's soaps are carefully made by expert soap-makers to ensure quality in every product. Each soap bar is produced through a cold-process method which does not require heat. This avoids damaging the active properties in the ingredients used. Foaming net is included. Add cold or luke-warm water and rub the soap bar to produce a rich lather. Gently apply the lather to cleanse your skin then rinse.
