I'm lucky that I don't burn thanks to being half Italian but I don't tan quickly either, it will take a good 3 days before I notice a difference and I usually reach a certain color and then won't get any darker, that's where Lancaster's Tan Maximeser comes into play!
It's essentially an after sun that will soothe and moisturizer your skin but at the same time stimulate the production of melanin to the intensify and extend the wear of you tan and guess what it really works!
I'm not sure how it does it exactly but I definitely notice a difference when I used this compared to when I haven't and the bonus is that it isn't sticky or greasy an is easily absorbed into the skin.
So next time you're waiting to board your flight at the airport pick up a bottle of this (it's always on offer) and be amazed!!!
