How can i prevent freckles while getting sun tanning ???

You can't: Freckles occur from sun exposure. If you skin is prone to freckling, you will freckle after you've been in the sun (or tanning). The only way to avoid freckling is to avoid the tan (sun screen, stay out of peak sun, avoid tanning beds). If you want the color without the freckles spray or self tan will get you a better result with less risk.

Impossible: It is not possible to prevent freckles while suntanning. Freckles are a sign of skin damage by the sun. We recommend sunscreen and protective wear to avoid skin cancer. Try some sunless tanning products. They are quite good to.get.the look you want, sans freckles!
