This is lovely. The particles are very fine and even and do not seem rough- my skin can be sensitive and this does not irritate it.
It is fine to use gently over spots (I don't rub too vigorously) and possibly helps some of the stuff to surface! I enjoy the heating sensation when it is first applied and I leave it alone before gently massaging and rinsing off. I think it does work to reduce the blackheads on my nose and overall my skin feels softer and smoother. I used it thrice a week initially and then twice a week. I would recommend it- not too expensive but a little more than an average scrub so maybe worth purchasing when there is a 3 for 2 or a Boots voucher.
