I’ve used proper fake tans and gradual tanners. I exfoliate before and my legs are moisturised (but I don’t moisturise immediately before putting the tanner on anymore). It takes on the rest of my legs and on my body, but I get no change in colour whatsoever on my shins, and very little on my calves. Knees and feet fine though (nice!).
I’ve used isle of paradise pre-tanner and that’s made no difference.
Any ideas?!
