A patch test is required prior to the treatment to ensure there is no allergic reaction to the hyaluronidaise which is the name of the product used to dissolve. We wait 30 minutes to ensure no allergic reaction. Anaesthetic or numbing cream can be applied before treatment and if no allergy to the product then the hyaluronidaise will be injected into the decided areas. After care is given and it is recommended not to apply make up for 24hrs after having this treatment
