Mixed in with this super sheer silicone-based primer are skin hydrators so it can replace the need for a morning moisturizer, or add additional hydration to thirsty skin. It’s a primer with a feel unlike most; not greasy or heavy, with a slight slip to give foundation something to hang on to leaving skin hydrated and balanced. It’s a fantastic primer for dryer skins to encourage a longer foundation wear time. At $45, Skinprep is a bit of an investment, but it’s more of a grown up primer for those whose skin isn’t automatically perfect without a little bit of help.
