I would suggest a light witch-hazel blend like Thayer's lavender or rose toner to follow it (if not just leaving it on its own, which also will work given the slickness). Then an herbal-type after-shave like Myrsol's agua balsamica or some bay rum. Since returning to France, I've been following it with Christian Lenart's Eau micellaire, 500ml, which is found in a local mega-supermarket here for around 4-5 euros. Really nice, Thayer's toner-like delicate stuff. Once it dries, its off to the only source of bay rum that I could locate here, Benjamins from Jamaica, which has a high-octane flash. All in all, I'm pretty happy with the sequence. No way that I would spring for the 50ml Osma options. But the original alum-Osma puck is a must!
