Glycerol/ Glycerine/ Glycerin/ Pflanzliches Glycerin

由脂肪水解或醣類發酵製得,也可以人工合成,它都是一種很好的保水劑,可以維持皮膚的障壁功能,避免產生乾燥或脫皮。如果使用100%純度在皮膚上,會從底部的真皮層吸收太多水分到表皮中,反而會增加水分流失的速度,所以必須和其他成分加在一起。將甘油、矽靈油(dimethicone)、凡士林(petrolatum)、抗氧化物(antixoxidants)、脂肪酸、卵磷脂和其他成分加在一起,持續使用一段時間,對於幫助皮膚修護、減輕皮膚炎症狀、恢復障壁功能的效果非常好
1克的甘油可約吸附0.6克的水

It is made by fat hydrolysis or sugar fermentation. It can also be artificially synthesized. It is a good water-retaining agent, which can maintain the barrier function of the skin and avoid dryness or peeling. If 100% purity is used on the skin, too much water will be absorbed into the epidermis from the dermis at the bottom, which will increase the rate of water loss, so it must be added together with other ingredients. Add glycerin, dimethicone, petroleum jelly, antioxidants, fatty acids, lecithin and other ingredients together and continue to use for a period of time, which is helpful for skin repair, alleviation of dermatitis symptoms, and recovery The effect of the barrier function is very good
1 gram of glycerin can absorb about 0.6 grams of water
