We don't want no scrubs - scouring is for dishes - and although physical face polishers still exist, they're no longer the über-abrasives of yore. Exfoliators come in many (three) different guises, so here's a quick guide to deciding which type's right for you...

{Physical}

For traditionalists (and the thick-skinned), physical exfoliators are effective when your skin's bunged up or looking parched. Containing tiny grains (usually finely ground 'organic matter' such as nuts, seeds, sugar, silica or even coffee), suspended in an oily balm or gel, these buff skin back to beautiful - physically 'lifting' the dead cells and debris that can can compromise its light-reflective properties. Best used sparingly (once or twice a week), they're ideal when you need to get skin glowing - stimulating blood flow to promote a youthful luminescence.

{Chemical}

'Chemical exfoliant' sounds scary, but don't be deterred. These acid-based resurfacers are often remarkably gentle. Invariably A/BHA (Alpha/Beta Hydroxy-Acid) based, they star things such as glycolic, salicylic or lactic acids (all of which are nature-derived), and target the bonds that bind dulling dead scurf to skin's surface. By dissolving this glue, they help shed the super-thin 'stratum corneum' - the oldest, uppermost layer of cells that contributes to dullness and makes skin look 'meh'. Best used overnight - and always in conjunction with an SPF - these dead cells are protective and without them, skin is more susceptible to ageing UV rays.

{Enzymatic}

Perfect for more sensitive skins, prone to blocked pores or congestion, enzymatic exfoliants contain fruit enzymes - papaya, pineapple and pomegranate are all common - which collaborate with the enzymes found naturally on skin's surface, to accelerate cellular turnover and 'gobble up' dead surface tissue. By refining skin texture in this way, cells are compelled to regenerate faster - which means signs of damage (scars, blemishes, dark spots) are diminished, and skin soon looks brighter and plumped-up. Enzymes are also less irritating than their chemical counterparts - therefore better for those with an easily upset complexion.
