About Dr Chung Wan Ling



Dr Chung Wan Ling is a GP Aesthetic Doctor with diplomas in dermatology and family medicine. Educated at National University of Singapore, Dr Chung joined the IYAC team in 2016, after years of training and employment in Singapore hospitals. She joined IYAC with a special interest in lasers, IPL and Ulthera therapies.


When asked about the secret to healthy skin, Dr Chung recommends an active lifestyle as well as rested one. She believes that exercise, sleep and nutrition are the secrets to healthy skin – and that medical aesthetics allow beautiful skin to be maintained through the years.


When she is not in the clinic, Dr Chung, an avid nature lover, enjoys long hikes in the great outdoors. She’s also a keen photographer, traveling to some of the farthest corners of the earth – including the remote Arctic – in search of the perfect shot.

IYAC’s treatments – many of which are non-invasive and require zero downtime – are safe and popular among young professionals, older executives, housewives and active parents from all walks of life.


At IYAC, expect a listening ear. We are here to listen to you, to hear out your concerns and to answer any and all questions you have about our services. After carefully explaining your options, we pledge to work together to create a customized treatment program to achieve the results you desire.

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.

Our vision is clear: 



We aim to live and work with meaning, purpose and passion by helping men and women to look and feel great while increasing their happiness, confidence and self-esteem through non-surgical aesthetic treatments, such as skincare, lasers, injectables and body contouring.



Our values are clear:


At IYAC, you can always expect:


  • Subtlety


We believe that less is more when it comes to aesthetic beauty. We believe the best way to look natural and fresh is through small, subtle changes that slow down the aging process. IYAC is known for using gradual, conservative techniques, especially with injectables, to create natural looking results.


  • Safety


IYAC offers safe medical aesthetic technology. We are not – and have never been – early adopters of new procedures or machinery. We offer treatments that have successfully been on the market for a period of two to three years. We try every treatment on ourselves first. We have complete confidence in our treatments and trust that you will feel safe and as comfortable as possible, as we understand what it feels like to be in your shoes.


  • Satisfaction


IYAC is all about personal attention and pleasant experiences. There is no hard sell policy. We listen to your concerns and provide a personal, customized plan just for you. In fact, over 80 percent of our business comes from word of mouth referral from satisfied clients.
