My main one is suncream, lots and lots and lots of suncream. I haven't been burnt in almost 5 years now (this takes a bit of effort, something I'm kinda proud of..!). Avoiding skin cancer, avoiding wrinkles, sun spots.
Also, use sensitive products on your skin. Try to avoid products with harsh/synthetic ingredients. If you want skin as smooth as a baby's bum, treat it gently like a baby's bum. Make sure products you use are PH balanced, it's worth reading labels of skin care product packets before you fork out. Read a few online articles about the science of skincare (not ones funded by big magazines or by skin care companies) to smart yourself up so you know what to look for in a product.
Also, remember that $ does not always translate into quality. Do your research. My favourite 3 skin care items are avocado, watered down lemon juice, and lucas paw paw. I go through shite loads of that stuff.
I usually wash my face with watered down lemon juice after I've removed my makeup with simple wipes (product plug!). Then witch hazel in an atomizer as a toner, then I use avocado (mushed up) as a facemask. The proteins in it are awesome and the oils in it are really moisturising. Important to not strip your skin of too much oil as then it will just over compensate. Don't forget the neck, ears, shoulders and decolletage when cleansing... These are on display alot. Also your ankles/feet and hands. Manis/Pedis are not just about nails, they also are about skin care.
Personally I also avoid fake tan as I'm not a successful tanner - some girls are (lucky them) but I look like shite in it. Find out what works for you, and stick with it. Play your own game.
I avoid makeup as much as possible. I never wear it when I'm not at work. Unfortunately at work, I have to wear it. If you are wearing makeup, quality and natural is key. Mineral Make ups are great. I still haven't found the right makeup for me though so I can't say too much about it. Zane, not sure if makeup is your thing?
hehe
Also, a lesson I am learning (for the millionth time because I'm a slow learner with a very sweet tooth!): Diet is key. I've been eating lots of sweets and unhealthy snacks and soft drinks lately and my skin is hating me for it... So back to hydrating (lots of water!) and eating healthy and then hopefully my skin will stop behaving like a 3yo.
Think I've said more than enough for now...
