Laura, i'm not sure if it's available in Ireland, but i found a drugstore exfoliator by Freeman to be gentle & effective.
however, for REALLY good exfoliation, i like Dr. Brandt's Microdermabrasion in a Jar & Philosophy's Resurface. i use either 1x/week & my skin feels as soft as a baby's. plus, it helps w/any dark scars from old blemishes.
