Regarding spray hair removals: they are not as good as they sound, in my opinion. I have tried Nair and Veet. First of all, be warned that cream hair removals like this smell FUNKY. In addition, do NOT leave them on too long. They will begin to take off a little skin when you wipe them off, and may sting a little. If you are looking for hair removal that lasts longer than shaving, consider waxing over creams. There are a lot of waxes on the market for sensitive skin and you get used to it. Leg waxing is not all that bad. If you are going to try the creams, do as Ana said and test a little patch. These are all my opinions from my experiences, so who knows, you may try one and love it. If you do, let me know!
Regarding self tanners, I use those gradual lotion tanners and they are the best. Jergens has a good one, but I prefer Dove's Energy Glow. It smells nice (much better than Jergens), it's easy on the skin, and it gives you a natural glow that builds everyday you use it. I have not used the instant tanning lotion kinds because every friend I have who uses them looks like a pumkin...with streaks. Not so fab.
