The wax used is safe for sensitive skin and does not contain pine tar (rosin), which may cause allergies. Although it is a hard wax, it is soft and stretchy rather than hard and stiff. It has a soft, stretchy texture that minimizes the pulling and peeling sensation of hard wax or soft wax with strips. The wax is hypoallergenic and painless. It also contains tamanu oil and vitamin E, which prevents redness and inflammation.
