I had my lips done at this clinic with Dr Teuta and couldn’t be happier with the experience. Dr Teuta put me at ease straight away. She took the time to explain the whole procedure clearly, talked me through what to expect, and answered all my questions before we got started, which made me feel confident and well looked after.
The results are exactly what I hoped for — natural-looking and beautifully done. I never once felt rushed, and the whole process felt professional from start to finish. Would definitely recommend to anyone considering lip filler and will be back again myself!

If you are considering injectables, I highly recommend booking with Dr. Arreni. From the initial consultation to the treatment itself, she was brilliant. She listened carefully to what I wanted and gave brilliant, honest advice. Very professional!

I cannot recommend Dr Elina Kovalenko enough!! I have been suffering with severe hyperpigmentation and she has achieved an absolutely incredible transformation. 🙏🏼✨🙏🏼 My skin is far more even in skin tone, the discoloration has been hugely reduced, everything is far more supple and vibrant looking. I don’t even recognize myself in previous photos as the change is that significant! I’m beyond thankful for all of Dr Elina Kovalenko’s expertise and guidance as without it I would have been utterly lost. She gives so much and goes above and beyond to help you and support you, I couldn’t have asked for a better doctor to help me. Thank you so so very much Dr. Elina Kovalenko
