You will find Damadi Skincare in the Star Arcade, just off the Smith Street Mall. It's nestled in a bunch of shops which include Simply's Vegetarian, Four Birds, Embella and the original Rendezvous Café.
It's a small shop. With a mere five metres squared, it fits a lot of love in. The shopkeeper is a local and prides herself on the handmade beauty goods that she makes.
