Spray tan blocking pores

Hi Girlies, haven't been on for ages, but need your advice

The last 3 spray tans that I have had, have made me look like I have really bad black heads over my chin. Which I assume is the spray tan getting blocked in my pores! Have had lots of spray tans before and never happened then.

The last 3 I had were all done by different people and 2 different brands of tan.

I have normal to dry skin and wouldnt say I have massive pores!

Has anyone heard of this before? And is there anything I can do? As although I have a beautiful tan, I have a dark mess on my chin :-(

Was thinking about booking myself in for some facials

What do you guys think? Any ideas? Or solutions?

Thanks xx

I had this at college, when I had my spray tan practice, had it all over my chest and face.
I have combination skin type with oily t-zone and dry cheeks.
My tutor said it was because I had open pores and no way of stopping it. This put me off ever having a spray tan.
