Hyaluronic Acid Booster contains a specialized matrix of skin-smoothing hyaluronic acid, skin-replenishing ceramides, and panthenol that penetrates skin’s surface to help lock in moisture, keeping skin hydrated and ultimately moisturized.

All Paula’s Choice products are 100% fragrance free, clinically proven to be non-irritating, and never tested on animals.

Visibly plumps skin, smoothing the appearance of fine lines and wrinkles—including fine lines around the eyes. Can be used alone or add a few drops to your favorite moisturizer or serum to see even better results. From first use, you’ll see noticeably smoother, more hydrated, younger-looking skin.

Dispense 1-2 pumps into the palm of your hand and then apply to your face. Add a couple more drops if you will also be applying to your neck and chest. During the day, finish with a moisturizer with SPF 30 or greater. Can be applied under the eye area, avoiding the eye itself.
