I also got Vaniqa prescribed to me, unfortunately my face had a huge acne reaction to it, and felt like my hairs were coming through faster (this is pre-hrt) as usually I'd have to shave 2-3 days apart but with that it was a daily thing - unless my testosterone levels were starting to rise(as I should be at my prime height of T levels but when I had my blood taken it was low) - if this is why I'm glad I got HRT when I did as now (only a week in) - I can go up to 4 days without shaving (though my skin will feel stubbly) and it's not visible.
So no experience with what you've seen but my Vaniqa cream was not good for me personally
