What is freeze-dried powder? Freeze dried powder is a powder made by removing water from high-purity active ingredients in a low-temperature vacuum environment. The entire process is not subjected to high temperatures, and the structure and efficacy of the active ingredients are maximally preserved - this is also the reason why it has long been favored by professional formulators. Compared with a bottle of prepared essence, lyophilized powder returns the choice to you: ·High purity without water, fillers, or preservatives, you get almost 100% of the active ingredients themselves. ·The concentration is controlled by dissolving with a matching solvent or your commonly used essence base. The concentration is adjusted according to your skin type and tolerance. Start from low concentration and gradually find the most appropriate level. ·Ready made, ready to use, ready to adjust, ready to use. The activity is not diluted by long-term storage, and every use is in a fresh state. ·One thing for multiple uses can be added to essence, lotion, face cream, or used alone as a nursing step. One bottle can be mixed for more than 30 times. Each bottle is individually sealed and packaged to avoid light and moisture, ensuring optimal condition upon hand. After opening and mixing, it is recommended to refrigerate and use within 14 days to ensure activity. Freeze drying powder is not "more expensive essence", but a more active skin care method - you are no longer just a user, but also the decision maker of your own formula.
