About Dr Isabelle Yeoh



Educated in Singapore, UK and Ireland, Dr Yeoh developed the IYAC brand around the philosophy that wellness is the foundation of beauty. She believes that treating the whole patient means embracing an all-encompassing inside-out approach to health and aesthetic beauty.  


This same philosophy led to the creation of IYAC’s skincare line, which features medical-grade skincare products that are clean (free of harmful ingredients) and effective. The skincare line supports Dr Yeoh's philosophy: skin that glows on the outside must first be healthy on the inside.


Dr Yeoh’s passion is to create natural, youthful and subtle-looking results that complement each individual. She often combines aesthetic treatments with lifestyle recommendations involving nutrition and supplements. This combination approach provides longer-lasting results while restoring beauty, self-confidence and quality of life.


In her free time, you can find Dr Yeoh in a yoga pose, skiing, discovering a new Ayurvedic retreat or hiking in some of Asia Pacific’s most beautiful forests, with Bhutan, Kyoto and the Blue Mountains counted among her favourites.


She loves a good book – paperback, not digital – on topics such as nutrition, leadership and happiness, and counts Jenny Santi’s “The Giving Way to Happiness” as the one book she never tires of reading. A Grade 8 pianist and music lover, Dr Yeoh’s ultimate form of relaxation is reading an inspirational book whilst listening to romantic jazz piano music.
