tactile therapy

Tactile Therapy

The ancient art of reflexology and acupressure have brought relief from aches and pains to millions of people around the world. D1’s tactile therapy consists of various-sized therapeutic “bumps” that have been grouped together at key acupressure points for the arms, hands, wrists and feet. These bumps stimulate trigger points in these areas, providing you with an acupressure massage.
