Lip filler has become as popular as getting our nails done. This cosmetic treatment is incredibly safe as long as it is done by a trusted healthcare provider.

Currently, only doctors, dentists, or registered nurses can administer Botox under Irish law. However, the same rules don’t apply to dermal fillers like lip filler.
