Dr Hennessy Aesthetics review

I contacted Siân to see if she could help me with constant teeth grinding. We fully discussed treatments available and I was more than happy to go ahead. The day after the treatment, the grinding had stopped, such relief. It has made a huge difference to me and I’m just sorry I didn’t get it done sooner. I would thorough recommend Siân!!

Dr Hennessy Aesthetics Review

I got my treatment little over a week ago so it hasn’t set in fully yet but so far I’m really pleased with the result. Siân was very thorough when marking out the areas to treat and also explained everything very well. She also keeps it friendly and lighthearted while remaining professional. I have already been recommending her to anyone I know interested in aesthetics a treatments. 

Dr Hennessy Aesthetics Review

Siân is amazing!!I have had Botox previously and while it gave me less movement, the result was minimal. I asked Siân to significantly reduce the movement between my brows and she did exactly that. It’s only been 1 week and my lines are gone already! So delighted and could not recommend her enough. She is very thorough and you feel safe and comfortable in her care.
