THIS IS THE CORRECT ANSWER
Doing my research this morning…this was the best answer they could come up with at the time. Here is another one. Sun tan lotion DOES NOT prevent you from getting burned unless it has a high SPF and you use it regularly and avoid prolonged exposure to UV rays. Lotion does moisturize your skin and moist skin absorbs light where dry skin reflects light. Many tanning oils also have SPF to protect from limited amounts of UV rays, however, oil is not the moisturizer that lotion is for the skin. Oil has micro reflectors that creates more effects from the UV rays. and contrary to popular belief, it
IT IS SCIENTIFICALLY IMPOSSIBLE for a sunburn to TURN into a tan. Once that skin is damaged, it’s coming off and perhaps what is remaining underneath is tanned….but that burned skin will not turn into a tan.
Just make it SMART and SIMPLE…use Maximum Strength MTII by Tantra to create more melanin so you can get darker faster. Tanning doesn’t cause cancer, burning does. Don’t burn, use MTII by Tantra and you can get as dark as you would like and it will last three to four months. Private message me if you would like, or go to¬†www.tantrahealthandbeauty.com
