I’ve been a client at S-Thetics for over 5 years and couldn’t be happier with my experience. Dr. Sherina and her team always deliver the best results with such professionalism. From VISIA face analysis and Hydrafacials to more advanced treatments like Emface and injectables. The clinic combines innovative technology with a personal approach, and I always leave feeling refreshed. I highly recommend S-Thetics to anyone looking for outstanding treatments and a team you can trust.

Miss Balaratnam and her team at S-thetics are second to none. I have been a client with the clinic for over 10 years and would not go anywhere else. The knowledge and attention to detail regarding every available treatment is incredible. I have recently been lucky enough to try the EXOMIND treatment, which has been transformational for both my mind (helping with brain fog and concentration) and my skin which is brighter and tighter. Can’t recommend highly enough!

I have been a client of Dr. Sherina Balaratnam for over 10 years and truly cannot rate her highly enough. Her unique combination of technical expertise and artistic flair consistently delivers subtle, natural results. Dr. Sherina’s ‘less is more’ approach means I never look overdone - just refreshed and like the best version of myself. Her work is so skilfully performed that it’s completely undetectable, which is exactly what I want from aesthetic treatments. She takes the time to understand exactly what I’m looking for and is brilliant at setting realistic expectations. I always feel safe, supported, and in expert hands. I feel incredibly lucky to have found her, but honestly, she’s so good I would travel hundreds of miles to continue being treated by her. Thanks to Dr Sherina, I genuinely think I look better now at 47 than I did at 37.
