1. Prepare a glass of clean water, and pour a proper amount of seawater bath mask to be tested into the glass.
2. Shake the cup gently. At this time, it is time to identify the true and false algae. You can judge whether it is true algae or false algae by specific phenomena.
3. The fake will sink to the bottom of the cup while shaking and vibrating. These sinks into the bottom of the cup are fake seawater baths. The more they sink, the more adulterated beaches there are! But there will be no falling objects when the real sea bath is shaking.
4, and the real sea bath will not sink when shaking. Because the real sea bath contains collagen, it will be released when it meets water, so that the particles of the sea bath stick together, while the fake sea bath does not have collagen, so the particles will not stick together, so there will be sediment in the fake sea bath!
