WHAT IS THE SCIENTIFIC EXPLANATION OF TANNING?
There are two different types of ultraviolet rays, UVA & UVB, both are required to tan. UVB “activates” and UVA “oxidizes” (browns) your skin’s melanin. The skin’s oxidation or tanning process continues even after your session, up to 24-48 hours! Individual genetics determine the amount of melanin and tanning potential.
