                                          uvB rays​:

UVB rays are also known as the "building" rays or "reddening" rays. These rays are responsible for increasing the production of melanin in your skin. The more melanin you have, the darker the pigments of your skin will become. Along with building up the melanin, these rays also build up your vitamin D levels.  UVB rays are great for building your base tan but they can also burn you if you don't start off slow with lower minutes. 


                                           UVA RAYS

 UVA rays are also known as "bronzing" rays. These rays penetrate deeper than UVB rays, reaching layers deeper into the epidermis. UVA rays oxidize the melanin in your skin, creating the bronzed or brown look to your tan. Although theses rays typically don't cause burns, overexposure to the rays too quickly can cause you to burn. UVA rays are best if you have a decent base tan already.
