Generally, freeze-dried powder is not harmful to the skin, primarily because it is usually made from certain cytokines. Freeze-dried powder offers many benefits for the skin, including achieving a skin-smoothing effect and enhancing skin hydration. It can also be used by individuals with facial wrinkles or poor skin condition.
