I started using L'Oreal Nutrisummer after seeing a magazine advert with Scarlet Johanssen in Cosmo. I'm an advertisers dream! Previous to that I had tried numerous fake tanners and body lotions with a hint of fake tan (Boots no 17, Piz Buin, St Tropez, Johnsons Holiday Skin), but none did the trick - leaving me either streaky or orange.
In my opinion, Nutrisummer surpasses them all. After having a shower, I just apply as I would normal body lotion and in a few hours I'm left with lovely tanned legs (I used the "Fair skin" version, although it is also available in "Medium"). With a bit of care, making sure it has been throughly rubbed in, there were no streaks or patches, even without using a body scrub to exfoliate first.
The only downside to this product is the smell. Those familiar with using fake tan will know what I mean when I say that it smells very strongly like stale biscuits, which I've not noticed using the Johnsons Holiday Skin.
Overall, this is something that I can live with and the good points more than make up for it. I usually apply it before bed and then a shower in the morning gets rid of the smell before work without losing too much of the colour.
Recommended to first time users of fake tan as well as the experienced. Currently available for around £7 for 200ml.
EDIT - also don't forget to wash your hands after applying - having orange streaks between your fingers is not a good look!
