i wouldnt recommend a moisturiser with fake tan in, as if you go in the pool it will come off your skin quickly.
I work in a tanning shop, and i would recommend either one of these two..
Go on the sunbeds for very low minutes for a week before your holiday, some places do a weeks course, start off at around 3-4 mins and work your way up..you may not seem like you are tanning, but burning doesnt mean you get a tan, so dont be tempted to highten those minutes.
I have very very fair skin too and hardly ever tan but this did work for me.
the second option i would suggest is going ahead with a spray tan. These can last up to 10 days depending on aftercare, and i would suggest using a waterbased moisturiser, especially johnsons baby lotion because it works the best. This gives an instant result that is very natural.
hope this helps. =) hollie x.
