the very best thing i've ever used on my skin is homemade... equal parts olive oil, ground coffee, sugar, plus a full spoonfuls of honey, and a splash of vanilla for enhanced smell.
i use this on my face and body. i just made a new batch yesterday using only the olive oil and coffee and it's pretty tricky to rinse off if you don't add in the sugar. somehow adding in the sugar makes it rinse better.
i'm into the olive oil as a base b/c it moisturizes so well, plus it is supposed to help prevent and reduce the appearance of stretch marks. coffee supposedly helps combat cellulite.
the best exfoliate i've ever used (and made my skin feel like silk) is completely drenching my body in honey and then scrubbing it off with sea salt.
everything i've described here is messy and takes ample time. none of these are quick on-the-go methods. however, i've tried tons of products, organic and not, expensive and cheap, and the things i outline here are hands down the two that make my skin the happiest.
on-the-go face care i like is that coQ10 by avalon organics: cleanser, toner, and lotion are all fancypants.
pricey but amazing.
