There's a number of posts re Botox and other cosmetic items in Bali. Several relate to Arc Clinic in Kuta.
For those that are in Seminyak, especially the northern end like Oberoi, Samaya - Dr Made Ita, formerly at the Arc Clinic, has opened shop right next door to Sanyas Suites on Jl Petitinget.
Surgery number is 0361 9958917 and Dr Ita will also give you her mobile number. If you'd like her mobile number or email address please contact me off-list.
My wife visited for botox and a dermabrasion and Dr Ita's rates are competitive or cheaper than Arc. Her surgery is immaculate and Dr Ita is a lovely lady and my wife is going back when we're back in Bali this week.
Dr Ita is presently studying for a Masters Degree in Anti-Ageing Medicine, so is well qualified and just a lovely, lovely lady to go with this.
