The IV drip program (NAD+, wellness drips) is a standout service where patients report feeling genuinely refreshed and energized afterward. Several visitors specifically praise the ability to combine IV therapy with facials or massage simultaneously, making it practical for tourists who want multiple treatments in one visit without wasting holiday time.
English fluency across the entire team — doctors, nurses, and admin staff — removes a major friction point for expats and medical tourists. Patients consistently note they never felt confused about what was happening, costs were transparent upfront, and staff explained technical differences between treatment options clearly before proceeding.
Worth knowing
Appointment-based booking only with no walk-ins, and you must contact them via DM beforehand. For spontaneous visitors or those without social media, this rigid system creates friction compared to clinics offering same-day slots or flexible scheduling.
Pricing sits noticeably higher than competing Bangkok clinics for the same treatments. One repeat patient acknowledged 'prices are steeper than others' but justified it by the doctor's skill — meaning budget-conscious patients might balk without knowing what they're paying for in advance.
