Before CJAY was a brand, it was a quiet mission — led by a man with an extraordinary mind, a deep well of compassion, and a determination to heal what others overlooked.
Jay, also known as Peerawat Jay, is the formulator and medical expert behind the CJAY range. His journey began while working in aesthetic dermatology, Jay noticed that certain treatments were damaging patients’ skin — causing redness,thinning, and extreme sensitivity.
His curiosity became a calling. Together with his father in law, Dr. Chanchai Chutsirimongkol, he developed a device to stimulate skin regeneration. As more patients came to him with damaged skin, he discovered a common thread: prolonged topical steroid use. This is where his pioneering work in TSW began.
Over the next decade, Jay quietly treated hundreds of patients with TSW — observing, learning, refining his approach with each case. His original TSW serum has been revised and perfected over the years, eventually becoming the CJAY Rejuvenate Serum you see today.
