Masking Up – A Dermatologist’s Guide to Maskne is written by Dr. Teo Wan Lin, one of Singapore’s prominent dermatologists and medical director at TWL Specialist Skin & Laser Centre.

Mask acne or ‘maskne’ for short is a new term coined during the 2020 COVID-19 pandemic, more precisely known as acne mechanica or occlusion acne to dermatologists. This book is written as a guide to the phenomenon, with skincare, makeup tips for the “new normal” of mask-wearing, as well as information on how to choose the right fabric mask.

Dr. Teo leads the development of a materials science research arm, Dr.TWL Biomaterials, that focuses on ecologically sustainable, novel biomaterials for skin applications. As the first dermatologist-led cosmeceutical textile company, the biomaterials arm develops cutting edge technology for new generation biofunctional textiles. A pioneer dermatologist in the field of biofunctional textiles development, Dr. Teo’s original research letter “Diagnostic and Management Considerations of Maskne in the Era of COVID-19” was published by the Journal of the American Academy of Dermatology, ranked the top* dermatology journal internationally, in October 2020.
