Expert Advice
Expert Advice
“We wanted to deliver known skin actives, such as Niacinamide, Glycolic Acid and Hyaluronic Acid in their pure form in simple formulations without too many ingredients to deliver efficacy, layer well into a skin regimen, such as with Kiehl’s Ultra Facial Cleanser and Ultra Facial Cream and allow users to customize their skin care according to their needs. The simplified formulas ensure the ingredients absorb fully into the skin. Topically applied, Hyaluronic Acid in our Ultra Pure High-Potency Serum 1.5% Hyaluronic Acid helps boost skin’s hydration, softness and reduces the appearance of dry, fine lines.”

Frequently Asked Questions
Serums are a way to introduce ingredients to the skin in a lighter-weight, more concentrated format – in this instance: Hyaluronic Acid. Hyaluronic Acid is a group of sugar molecules that are naturally occurring in the body but can also be sourced from plant material. Hyaluronic Acid serums can attract and retain moisture in the upper layers of skin to keep it hydrated and visibly plump.
Yes. Hyaluronic Acid serums are safe for use every day and can be used both day and night. You may also use our Hyaluronic Acid Pure Serum in partnership with any of our other serums.
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.
Hyaluronic Acid will help the skin to appear plumper and more hydrated looking. Additionally, the greater hydration levels allows the skin to be more resilient and elastic which can help reduce the appearance of static lines and wrinkles.
