The Hyaluronic Acid Serum

Sale price$75.00
Quantity:

A lightweight, non-comedogenic hyaluronic acid serum designed to hydrate dehydrated skin while supporting the skin barrier. This formula delivers water-based hydration without heaviness, stickiness, or pore congestion. Dehydrated skin lacks water, not oil, which is why lightweight hydration is essential even for oily and acne-prone skin.

This hyaluronic acid serum hydrates at multiple levels, improving surface smoothness and overall comfort while helping maintain  skin hydration levels. With consistent use, skin appears more balanced, supple, and stable. 

Not all hyaluronic acid serums perform the same. Many create temporary surface hydration but fail to support long-term balance. A hyaluronic acid serum is a humectant-based formula that helps attract and retain water in the skin to improve hydration and barrier function, but this hyaluronic acid serum takes a treatment-room approach, delivering hydration without occlusion, remaining compatible with sensitive and acne-prone skin, and supporting consistent daily use without irritation. Hydration is not just about adding water - it’s about helping the skin maintain it.  

Suitable for dehydrated skin, oily but dehydrated skin, sensitive or reactive skin, acne-prone skin needing hydration without congestion, and over-exfoliated, sensitized skin, post-treatment or compromised barrier. 

Not intended for those seeking heavy, occlusive moisturizers or for extremely dry skin without layering with a  Onerta® Cream Barrier to help lock in hydration.

HOW TO USE

The Hyaluronic Acid Serum is formulated for AM/PM use for all skin types and tones.

In the morning or evening, apply 2-3 drops of the serum to the face and neck. Gently smooth into the skin until absorbed. Follow with your favorite moisturizer and eye cream.
