I nearly didn't buy it, because it claims improvements after 1 day and I get really cross with ridiculous claims on these products. But, it was reasonably priced as these things go, and recommended on Mumsnet, so I used it last night and this morning I couldn't find a single blackhead worth squeezing. I can often spend 10-15 mins picking. Yuk! So thank you, I think I may have witnessed a present day miracle.
