Thank you for reaching out! Each bottle contains 2% Hyaluronic Acid, please shake the bottle well prior to each use. This serum is one of our thickest facial serums that we have because Hyaluronic Acid itself, is very thick. There is no getting around that. If you prefer a thinner facial oil, please consider trying our Normalizing Face Oil. That product will be much much thinner and more suitable for your preference.
If you have any questions or concerns, please contact us at email@example.com, so we can further assist you. Thanks for being a customer!
