The most important thing is to never have a dermal filler treatment done at a beauty spa or salon. A non-surgical filler treatment is still considered to be a medical procedure that requires proper training, knowledge, and technique, so it’s in your best interest to consult a professional aesthetic doctor. A qualified doctor will be best placed to advise and plan a dermal filler treatment that is customized to your needs. Given the complex anatomy and presence of many blood vessels in the face, there is a high risk of serious complications such as necrosis and blindness if the procedure is performed by non-qualified personnel. Improperly injected fillers can also result in other undesirable side-effects such as infection, swelling and visible lumps under the skin. Hence it’s always important to make a consultation first and make sure you’re comfortable with your doctor
