Each PaloVia laser comes with a 1 oz. bottle of PaloVia Gel. When it’s time to replenish, remember that you can only use PaloVia® brand Pre-Treatment Gel with the PaloVia laser. When applied to clean, dry skin around the eyes, the PaloVia Gel ensures proper operation of the Handpiece, proper contact with the Treatment Window and optimal light penetration during treatment. The 1 oz. gel bottle will last for approximately 60 treatment sessions – or about 7 months of Maintenance Phase treatments (twice per week). Shipping is included.
