Hyaluronic Acid may be beneficial to some who are prone to acne. Skin may produce excess sebum when it is dehydrated. In those instances, excess sebum can build up and clog pores. By increasing the hydration of the skin barrier, it may trigger the skin to produce less sebum which can help resolve some of the issues. Additionally, for those who have post-acne texture, Hyaluronic Acid can help plump the skin giving it an overall smoother appearance.
