SPRAY TANS
I think that as far as spray tans go San Trope gives the best colour.

SELF TANS
I am medium skinned, and use Dove Summer Glow Body Lotion year round. I look disgusting white. There's something about a tint of colour that seems to enhance the features and blend out imperfections. I use it ON MY FACE TOO!

Its actually a really nice body moisturizer too. I was using a hellishly expensive Estee Lauder Renutriv one and cant see much difference. I used to use Johnsons Holiday Skin, but it went patchy quickly.

Its pretty light though so for serious colour use a stronger tanning cream. Please let me know what works for you so I can pass it on.

CELLULITE
Those little plastic cellulite massagers do work if you use them regularly.
I like (Dove again) moisturising shower cream. I can't remember its exact name, its in a white pump bottle. You need to use a bit of water, get up a lather and work the massager in a circular motion.
My man Michael who is trained as a Naturopath explained that "White people" tend to form hard yellow fatty deposits which is why they get cellulite. So, great. Brown and dark raced people don't need to use tanning products and aren't as susceptible to getting cellulite! Not fair is it? But they do need to use sunblock!
