远在千年前，黄瓜水、丝瓜汁擦肤涂脸，红花抹腮，指甲花染发等朴素的天然化妆品历经现代科技的发展，原料和调配技术已得到了极大的提高。化学、物理学、生物学、医、药学等多门学科和许多新的原料、设备以及新的技术已广泛应用于化妆品的生产。
当代化妆品品类繁多，大部分是由化工原料组成，一般是水和油的融合物，而且功效比较单一；从长期效果来看，具有正面作用的化妆品微乎其微，业界认为化妆品就是伤害皮肤的代名词，这些化学物质不但有损皮肤的健康，而且还会通过皮肤的吸收并随着时间的积累逐步积累在人的机体内，危害健康，增加诱发疾病的机会。
最大限度地减少化学化妆品给人体健康带来的污染和伤害，历经10多年的探索和实际应用，以现行化妆品无可比拟的优势，给人类的健康美丽带来了时代的崭新世界：一系列安全有效的、护理与美容并重的、多重功效的、无公害的、环保的生物酸化妆品承担了这一健康使命。
生物酸类物质在医药保健方面，特别是在皮肤健康的防治方面早已得到了科学验证；由于具有改善微循环、改善细胞通透性、激活和促进细胞新陈代谢、去腐生肌、加强局部营养、调节和增强免疫功能、抗病毒、消炎止血、抗衰老、抗溃疡等作用，因此不但在保健方面有着积极的作用，而且是非常有利于皮肤健康的，也是现行化妆品无法做到的。
生物酸类物质含有大量的活性功能基因，可以通过吸附、络合、螯合等作用与现代化妆品中的重金属及相关一些有害物质发生反应，达到缓解、除去或回收这些成分的作用，就像在工业废水处理和环境污染的防治以及农药的降毒等方面，一样显示出出色的绿色作用。
生物酸类物质属于天然和植物发酵物，它不但分子量小、活性高、更安全，而且更容易被皮肤吸收利用，它溶于水，并具有抗酸碱的缓冲能力，既可作主剂、也可作辅剂、增效剂、稳定剂、缓释剂。这些功能对于化妆品的调制、生产是非常有利的。
生物酸化妆品具有现行化妆品无法达到的多重功效，在用于紧肤抗皱功效时，同时抗炎抗菌，保护皮肤，延缓衰老；在用于嫩肤美白功效时，同时营养皮肤，防治某些皮肤疾病，做到美容与护理并举；在用于维护口腔健康时，同时具有消炎、抗溃疡和止出血作用；在用于头发定型时，同时具有营养毛发的作用；在用于口服美容剂时，同时具有消炎、改善微循环、健康肠胃、调节机体免疫力等积极作用。

Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
