The Ordinary Hyaluronic Acid 2% + B5

The molecular size of HA determines its depth of delivery in the skin. This formulation combines low-, medium- and high-molecular weight HA, as well as a next-generation HA crosspolymer at a combined concentration of 2% for multi-depth hydration in a water-based formula. This system is supported with the addition of Vitamin B5 which also enhances surface hydration. 

Note: Hyaluronic Acid is found in the skin naturally but its natural function within the skin is not hydration. Many products have used HA to claim hydration benefits, but HA is too large of a molecule to penetrate the skin and instead sits on the surface and can draw moisture out of the skin making the surface feel soft and hydrated temporarily, while making you feel like you need more HA after the product is rinsed. This formula uses three forms of HA with varying molecular weights, as well as an HA crosspolymer, to offer multi-depth hydration and visible plumping without drawing water out of the skin solely to improve temporary surface hydration

Apply a few drops to face AM and PM before creams. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children.

Patch tests are an easy way to help predict if you may experience a negative initial reaction to a new product. It is recommended to perform a patch test before incorporating any new product into your regimen. We have outlined a general method for conducting your own patch test below based on the type of product.

• Apply a small amount of the product onto a clean area of skin on the upper forearm.
• Keep the area dry.
• If the product has a specified duration of use, rinse off after this time has elapsed. Otherwise rinse off after 24 hours.
• If any redness, burning, itching, blistering or irritation is observed at any time throughout the test, do not use the product.
