Silicone Spray is a fine mist which provides the skin with a breathable barrier against the environment.  It helps lock in and protect against moisture loss.  When used as a make-up primer, it helps fill in and smooth the surface of the skin for a flawless makeup application.  It is excellent for daily use on extremely dry skin because it protects the tissue and keeps the skin hydrated.  It will not irritate sensitive skin or vulnerable skin post medical aesthetic procedures like Microdermabrasion, IPL, Microneedling and/or chemical peels.  The key ingredient is dimethicone.
