Dr Isabelle Yeoh is the founder of IYAC, a brand she established in 2005 with the belief that wellness is the foundation of true beauty. Educated in Singapore, the UK and Ireland, she developed IYAC with a philosophy that emphasises the connection between body, mind and relationships in achieving lasting health and radiance.

Dr Yeoh’s approach centers on addressing the individual as a whole, blending aesthetic treatments with guidance on nutrition, lifestyle medicine and emotional well-being. She believes wellness is not just about looking good or feeling healthy but about living on purpose, nurturing relationships and making mindful choices that support the mind, body and soul’s needs for growth and self-acceptance. She views ageing as a time to draw on life’s experiences, using them to bring understanding and positivity to those around us while fostering deeper connections and a sense of fulfillment.

In line with her belief that beauty begins within, Dr Yeoh created Forest MD, a botanical skincare line designed to support healthy skin while being gentle for sensitive skin. Formulated without common irritants and using carefully curated active ingredients, these products reflect her commitment to skin health and well-being.

Dr Yeoh loves exploring wellness retreats around the world, where she reconnects with practices that inspire tranquility and balance. She also enjoys hiking, skiing and drawing energy from nature, with the forests of Bhutan, Kyoto and the Blue Mountains among her favourite escapes. Listening to music grounds and inspires her, whether through the rhythms of drums, the emotional melodies of the violin, or the graceful sounds of piano. A Grade 8 pianist, she often relaxes with music accompanied by a meaningful book.
