As someone who regularly tans and finds myself battling the dreaded neck/face tan line, I decided to invest in a decent face tanner. We wash and cleanse and exfoliate our faces every day, so it's no surprise our faces struggle to keep a tan for as long as the rest of our bodies. I decided to try to St Tropez gradual tanner, which I use most nights just before bed like a night-moisturisor. Every few days when my face is at a good colour I'll use my Nivea night moisturiser instead, to keep my skin on good form.
It doesn't smell at first but as with most tanners by morning it develops into a slightly biscuity smell. Not the most terrible tanning smell by all accounts though. I can't remember quite how much this tiny bottle cost, about £12 I think but it has lasted a lot longer than I thought it would and in the morning my face is a nice brown tan rather than orange. It doesn't seem to streak very easily either, which is a bonus. I squeeze a pea size amount onto my hand before rubbing in all over in circular motions.
I would recommend this and would buy it again, it does what it says on the tin and seems a good value for money. I've been using it for over a month now and my face has safely kept up with my body, which is mission accomplished from my point of view.
