I put off using it until it started to get a bit warmer and skirts were being worn! I don't really know what I was so worried about as it was "relatively" painless and easy to use.
Warm the sugar in the microwave until it has the consistency of runny honey and test is for temperature so you don't burn yourself. Allow a bit to cool on a spatula and apply to the leg or arm. If the mixture is still on the hot side then allow the mixture to cool for 5-10 mins before testing again.
Then use as you would a wax system, applying carefully and thinly to areas you wish to remove hair. The benefit of a sugar system is that it doesn't adhere as much as wax so it won't pull off more than a few thin layers of skin with the hair (saves me exfoliating).
I found it easy and pleasant to use, the great thing is that you can apply the sugar to the whole leg and then only really need to use two to three strips as you can use them more than once. This makes it really speedy! If you make a mistake or it gets on towels then it is easy to wash out with warm water. The sugar only needs to be warm for application, it remains sticky so you can use the strips in succession.
I haven't used this on the face as I am still considering laser so don't want to mess up my hair growth by removing roots. I did use it to shape a friend's eyebrows the other day and it worked really well. In fact much better as if any gets on eyelashes, you can wipe it away with damp cotton wool.
This system is a definite repurchase for me as I have tried and failed to make my own sugar mixture and now can't be bothered to keep trying! I'd rather just buy a sure fire system! I'd say that if you were doing legs, underarms and bikini once every 2-3 weeks (6 weeks? no way!) this would last about 2-3 months (4-6 full applications).
