One of the Korean beauty brands just released a new line that features sea salt, specifically magnesium + calcium salt and claims that the benefits to be had are:
1. contain excessive sebum secretion
2. prevents moisture from escaping the skin, in fact the sea salt "pulls the water charges" to the skin... do they just mean it's a humectant?
3. improves elasticity in skin
4. potassium is deposited and "fills the pores"
I've never heard of salt being used in skincare before. Are these claims way out of line or do they hold some merit?
