The E-Swin-Gel is applied in thick layers during a session. Once used on the skin, it should under no circumstances be collected and reused elsewhere, as the flash will modify the optical properties of the gel.
Correct optical transmission is not possible without the use of a good gel that is colorless. All of our clinical studies have been performed with this gel.
Using other non-clinically tested gels can cause skin burns and will void your device's warranty.
