  • What form of hyaluronic acid is best? Low MW problematic causes eye irritation and feels dry

    Posted by Zink on May 16, 2019 at 4:06 pm

    So very low molecular weights can irritate eyes and possibly feel drying/cause milia. 

    Very high mw versions don’t penetrate the skin but feel good / act as gelling agents.

    Is HA a useless ingredient or are there forms that work without these issues?

    None of the hyaluronic varieties penetrate through stratum corneum as even ultra low molecular weight is larger than 400 daltons. I personally find it overpriced and useless.
