Passage ThreeWhen you stretch out in the sun you can do one of the three things: you can use no sun tan oil, an ordinary sun tan oil; or Bergasol.If you don't use any sun tan oil when you're in the sun, you will burn surprisingly quickly. If you use an ordinary sun tan oil, you will protect your skin to a lesser or greater degree. How much protection depends on the "protection-factor number" on the bottle. Some oils block out so many of the sun's rays and you can stay in the sun all day without burning but you won't go very brown, either.Bergasol will protect your skin like an ordinary sun tan oil. It also has a tan accelerator that speeds up the rate at which the sun activates the skin cells that produce melanin(黑色素). It is melanin that gives the skin its brown colour. Bergasol enables you to go brown faster, am as the days pass the difference will become more obvious. Unfortunately, this special formulation isn't Cheap to prepare. So Bergasol is rather more expensive than ordinary sun tan oil. However, the price looks more attractive as you do.BergasoiIt makes you go brown fasterProtection Many people imagine that "cover-up" means you don't get a tan.
