Pore vacuuming is very much the latest trend in facial care. However, unless it is done as part of a skin care programme, along with proper facial cleaning and followed by a suitable face mask, (for example a charcol peel mask) simply buying one of the rather gimmicky pore vacuum devices is a waste of money and time.
Remember that what you are likely to see is more than likely sebaceous filaments, which are totally natural and will never disappear. They're designed to be in your pores. You can temporarily remove them, but they will always come back as soon as your skin produces oil and sebum, which is does every day.
The "professional use" pore vacuuming models use a handheld device which has a rotating nozzle at its tip that inserts an acid based solution which is then sucked out along with any dirt, excess sebum and any dead skin cells. After this treatment a suitable face mask is then used or what is known as "red light" therapy.
Skin vacuuming will not get rid of acne. It may help to give the skin a short term glow and repeated treatment can help to maintain that glow. However, proper use of an AHA based cleanser (such as a Glycolic or Mandelic Acid Cleanser) along with oil free moisturiser and other skin products designed for acneic and/ or oily skin will produce a more lasting radiant complexion.
If blackheads are an issue, some time spent with your fingers and some tissue is much more likely to be of greater help than any cheap pore-vacuuming devices!
