Lactobionic acid
乳糖酸
分子式:C12H22O12 分子量:358.3 Cas No:96-82-2
半乳糖分子與葡萄糖酸分子結合而成,本身結構與作用上與粘多醣(Glycosaminoglycan)有些相似,具有良好的保水性,並藉由抑制氫氧基形成,達到抗氧化之特性,能再生表皮組織,結合膠原蛋白,以進行修補作用,研究顯示添加 8%以下無毒性及刺激反應,實際運用時機與果酸(AHA)相似[1]。

號稱第三代果酸,加大果酸分子量、緩和刺激性,去角質效果會較遲緩,但增加了保溼力[1]。

Lactobionic acid is the brother or maybe the sister of gluconolactone. Usually, it’s called a PHA, though some studies call it bionic acid or aldobionic acid. Not that this matters too much. What matters is that it’s similarly awesome to gluconolactone. So go read about gluconolactone to get the idea.
In a nutshell, it’s a next generation AHA, with almost all the benefits and more and without the irritation. It gently lifts off dead skin cells and makes your skin smooth and even. It moisturizes and helps the skin barrier. Can be used on sensitive skin too or post cosmetic procedure. In the long run, it has anti-aging benefits (though a tad less than AHAs), and it’s even an antioxidant.
