Thank you for your response. The Gold and Silver Gel have different properties / ingredients and have been developed to help with different aspects of your treatment when using them alongside the ZIIP Device. To give you an idea ; the Golden Gel helps with filling and firming - helps to firm and tone the skin and improve the dullness by giving you a bright glow and lift after treatment. It is also idea for poor circulation by helping the blood flow to the surface of the skin. The Silver Gel helps with brightening and plumping - ideal for use on sensitive skin or one that has rosacea. It helps with pigmentation and signs of age spots as well as for use on skin that suffers from acne.
I hope this helps,
