Another cheap and good beauty essential are MyBeautyDiary facial masks. It's nicely packaged with at least a dozen different essences for you to choose from. Unwrap and place on your face for about 20mins.
It's relaxing aromatherapy, I do find my skin more moisturized after, so its a great weekly beauty treat for yourself. It always feels cold on application that is a bonus for our hot weather. $16.90 per 10 pack, I tend to get mix packs so I get some variety, occasionally there are limited edition essences for mother's day etc.
