Eternity flowers are created by first selecting fresh blooms at their peak. These flowers are then immersed in a glycerin-based preservation solution, which replaces the natural moisture in the flowers' cells with glycerin, maintaining their softness and flexibility. After preservation, the flowers are often treated with eco-friendly, cosmetic-grade dyes to restore or enhance their original color. Once the flowers have absorbed the solution, they are slowly air-dried in a controlled environment to ensure that the petals, stems, and leaves retain their structure and shape. This process allows the flowers to remain visually fresh and long-lasting for several years.

永生花的制作首先是挑选处于盛开状态的鲜花。这些鲜花会被浸泡在含有甘油的保存溶液中，甘油会取代花朵细胞中的天然水分，从而保持花瓣和茎的柔软性和弹性。经过保存处理后，花朵通常会使用环保的化妆级染料进行处理，以恢复或增强其原本的颜色。待花朵完全吸收溶液后，会在受控的环境中缓慢风干，以确保花瓣、茎和叶子的结构和形状得以保留。此过程使花朵能够保持外观上的新鲜感，并且可以长时间保存，通常可达数年之久。
