For years I've had a prominent 'line' (I hesitate to call it a wrinkle because that doesn't seem right...but then I can't think what it would be called) across my forehead. Perhaps from frowning too much

But anyway, I've seen smoothing products for men before (I think L'Oreal do some?) and just wondering if theres any people would recommend for a fairly cheap price (sub-£10?) and any body whose got experience with them (and their effectiveness) that'd be great.

Thanks in advance.
