Kiehls is by far one of my favourite skincare brands and when they launched the Micro-Blur Skin Perfector, I couldn't be more excited. A primer (or "skin smoother" like they call it) with skincare benefits to it? Yeah, I'm up for that.
Generally I'm not one to believe in skincare benefits from cosmetics, but I honestly think this does what it says. It contains Lipo Hydroxy Acid, Bark and Lentil Extracts, which aid to hydrate the skin and pore correction over time. Now I haven't noticed any pore correction so far (sadly), but I can vouch for the hydration bit —my combination/dehydrated skin is simply loving it.
I like to smooth this over my nose, cheeks and forehead (after my moisturiser) and let it sink in for about 1-2 minutes, before I continue with my base. I can't say it makes my foundation last longer, as I tend to powder my face due to the 'natural dew' it gives me throughout the day, but I do think it makes my skin look smoother, plumper and just better.
