hi,
sunscreens are usually tested for 80 minutes of efficacy.
for example, if a company was making a SPF 15, the SPF would have to be at or above 15 at minute 1 and minute 81.
most sunscreens should be reapplied every two hours, and it's about 1oz (a shot) of sunscreen you should be using for your whole body each application.
have fun in the sun and be safe!
At least 15 to 30 minutes before hand.
Well actually according to a news article on 'PREVENT SKIN CANCER' we should apply sunscreen at maximum 20 minutes prior to going out in the sun and always would sunscreen on face, arms, legs, back (if at beach), back of ears where sun exposure can affect and nape of neck. Keep safe. :)
We should apply sunscreen even if it is nit sunny.
this really depends on your spf. I normally reapply every 3 hours and when some says i am getting red
There is no waiting time, in fact, you can apply sunscreen while you are actually IN the Sun!
Every 2 hours.
30 minutes

You should bring sunscreen to the Barbados Resorts. Barbados can be very sunny and if you are outside for a long time, you can get sunburned. To protect yourself wear sunscreen.
That depends almost entirely on the type of chemical in question. other factors include the size of the pool, and ration of water to chemical additive
I would assume it would last for around 20-60 minutes in the water depending on the brand you would be using
depends on how long the sunscreen your using says it can last (e.g some go for 4 hours)
you will have to wait a month
By applying slow amounts of water to the soil over a long period of time, the soil can absorb the water more quickly. It is the most direct form of irrigation, by applying water where only it needs it less is wasted and results in reduced water. By applying it slowly there is more time for the plant to soak up the water before evaporation.
You should apply the Clinique sun broad spectrum spf50 sunscreen face cream where you need long lasting protection from the sun. Ideally this should be applied in the morning for long lasting sun protection. It can be applied before make up and by hand gently massaging into the face.
Fifteen to thirty minutes.
