Hyaluronic acid is a molecule which we already have in our skin. It’s essential in helping the skin retain a youthful appearance. The molecule can hold over 1,000 times its weight in water. So it’s no wonder that hyaluronic acid has gained so much respect as an excellent way to improve hydration.
We know that some people are turned off by the word acid. However, hyaluronic acid is a gentle acid, with a pH between 5.0 and 8.0, which complements the skin's natural pH which hovers between 4.5 and 6.2.
