Botox freezes muscle movement by blocking neuro-transmitters and this effect lasts for 4-6 months – this means you will need top-ups a few times a year if you wish to maintain your line-free look.
Once you’ve had Botox injected, the effects on the muscles usually become apparent within a few hours, with the main effects appearing after about a week.

Are the injections safe?
Botox is a relatively safe treatment, but it should always be undertaken by a qualified medical professional to ensure that you are getting the correct amount in the right area.
Visiting someone without the correct qualifications and experience could lead to asymmetrical results, muscle drooping, frozen expressions as well as various other dangerous consequences.
