Mushroom Extract

Much of the mushroom extract in iS Clinical formulas comes from Polyporus umbellatus, a natural source of kojic acid. Mushrooms are also rich in polysaccharides, which attract and hold moisture, so the extract does two jobs: it helps the complexion look brighter and more even, and it leaves skin feeling plumper and smoother. Natural antioxidants add support against everyday environmental stressors.

Brightness is the common thread in this collection. Warming Honey Cleanser starts the routine at the Cleanse step. Brightening Serum, Super Serum Advance+, Poly-Vitamin Serum and Youth Serum with Copper Tripeptide-1 each place mushroom extract in the Treat step, and Brightening Complex seals it in as you Hydrate. Finish with an iS Clinical SPF at the Protect step. Read more in our guide to mushroom extract.
