Chemical formula

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.
