10/10. My husband had the curcumin drip before we travelling back to the UK. His legs and knees didn't give him any grief like normally did every time he travelled. Very happy with the result and excellent staff members. Highly recommended.

Dermarest Clinic offers a truly elevated wellness experience. I received the Liver Detox IV and was deeply impressed by the serene atmosphere, refined care, and attention to detail. From the warm, professional staff to the thoughtful touches like fresh fruit and lemon water, everything reflects the clinic’s high standard in integrative health. A sanctuary for those who value wellbeing at its finest. ✨💧

I was recommended this clinic by a close friend and I am not disappointed. Their doctor spent along time with me reviewing my results and came up with an affordable plan to get me back to maximum health. The customer service and care is world leading. Aura on reception replies to my what’s app messages efficiently and effectively and Mor my nurse is very attentive and caring. Great service all around.
