My favourite masks all use fruit, and in my experience, are gentle enough to use on all skin types, although you ARE in danger of eating them...
I like to mix 1/4 cup of a peeled diced apple (the smaller the pieces the better) with 1/2 cup of greek yoghurt, 1/8 a cup of oatmeal and 3 tspn of honey- melt it in the microwave to liquify it. If you can get New Zealand Manuka honey, all the better, because it has a healing and soothing effect on all skin types. I let it cool in the fridge until the honey is no longer hot, and then smooth it thinly as possible over the face, making sure to avoid the eyes. Leave it on for ten minutes, or as long as comfortable, and then scrub off like an exfoliator.
Also, mango pulp and egg whites mixed together make a nice and soothing mask which also draw out impurities, as well as smelling fantastic!
Greek yoghurt mixed with oatmeal and lemon juice makes a great exfoliating mask, as the citric acid in the lemon juice leaves the skin looking fresher and brighter, and the oatmeal has an exfoliating effect when removed from the skin as though it is a mechanical exfoliant. Greek yoghurt is hydrating and soothing on the skin also.
