This is a traditional beauty bath that has been enjoyed by Javan princesses for many centuries. For them, the bath was seen as an elixir of youth – a way to stay beautiful and lively for all of eternity. Now, while the Mandi Susu can't quite deliver on that promise, there's certainly a grain of truth to these old tales. The bath itself is prepared by adding milk – traditionally either goat, sheep or cow milk. Buttermilk and or yoghurt is also used for more intensive treatments. Once a person's skin is soaked in the milk for around 20 minutes, they are requested to leave the tub and relax for some additional time – all without rinsing the skin. Through this process, the skin becomes soft to touch and starts to look purer.
