At what age can I start applying Botox?Yes, provided they have been approved by the health department of your country and the proper injection technique is employed. It is imperative to visit a reputable doctor with lots of experience in dermal filler injection. Also, the injector must choose the right filler for you. FDA- approved hyaluronic acid fillers designed for lip augmentation are safe and produce the best results. Finally, always ask your doctor what type of filler he will use and never buy fillers online.
