Colloidal Gold

Colloidal gold is a suspension of extremely fine gold particles in liquid. In skincare it is prized for its antioxidant qualities and for the radiance it lends the complexion, helping skin look luminous, smoother and more refreshed. It also helps skin feel comfortable and contributes to a silky, refined texture in the formulas that contain it.

Within the iS Clinical range, colloidal gold is part of Retinol+ Emulsion 0.3, where it sits alongside retinol, bakuchiol and ectoin. Together they create a Treat-step formula that helps skin look smoother and more even while staying comfortable. Use it after cleansing, then Hydrate with your usual moisturiser, and wear SPF each morning. Read more in our guide to colloidal gold.
