Uniqueness of Sai Serum
Sai is supposed to be mildly grainy. The graininess/
Duan Shi Gao’s very fine powder is mixed in and suspended in Sai formula. However if you open up the bottle to look, it may look clumpy. This is because naturally, gypsum draws & holds water from its surroundings. This causes gypsum to expand even in suspension. However gypsum releases water out when it’s warmed. It is a pretty fascinating process actually!
