The manual provided is very clear and complete it we step guide (with great caution) for optimal use of Lumea. A month is a little short to test this product. Philips recommends at least 4 uses for achieving tangible results (ie 2 months with biweekly use as recommended by the brand). Anyway after two uses I have already noticed a positive effect. Most darker hair (on my fair skin) does not grow, because the more the hair is dark over the Lumea is performing. For lighter hair, they grow back finer, perhaps they disappear with an additional two weeks, this remains to be confirmed. Having scrupulously follow any of the Philips Board I have seen on my side effect yet fragile skin. The Lumea should not be used in body parts such as ears or near eyes, and on the parties very "sensitive" or on the face for men (why? No idea ...). For people with many moles, careful brand warns and recommends the advice of a doctor. The use is somewhat more restrictive than for a standard waxing. We must first shave the hair (without irritating the skin to have no skin reaction) and then flash stepper any desired area by successive support. Although we talk about permanent hair removal, do not be naive, all your hair will not disappear, this type of hair removal allows, however, a much less regular waxing. I recommend to all allergic hair!
