Skinfood Pineapple Peeling Gel (reviewed here) - My go-to exfoliator when my skin feels like it needs a good scrub. It's a mix of physical and chemical exfoliant, and it lives in my shower caddy pretty much permanently.
PVA base coat (how to make it here, troubleshooting here) - I've used this under the manicures that contain glitter, or that I might layer glitter on top of later (i.e. all of them). So much easier to remove, and on my nails, it doesn't do any damage.
Models Prefer Cleansing Brush (reviewed here) - I only picked this up recently, but I've used it almost every second or third day since. It turns any cleanser into a scrub, and makes my skin feel properly clean when I need to remove foundation.
Rose Hip Oil (reviewed here, here, here and here)* - This has reduced breakouts significantly, and whenever my skin plays up, it's likely that I've been lazy about the RHO.
