Sun PotionPearl Powder (Sustainable, Freshwater) - Beauty & Spirit Tonic (80g)

Is this finely milled? Is it easy to mix with creams, I have tried the moon juice and that one is hard to mixed with moisturizer as it gets clumpy. ?

What is the exact particle size? Is it a nano-particle?

My bottle arrived without a seal on the outside or a glued paper cover on the lip of the item. Is it supposed to come without the seals?

Is this hydrolized?
