Tingles give you the deepest, darkest tan possible. They bring blood to the skin surface and, essentially, oxygen to affect the skin’s melanin. The more melanin that’s affected, the darker your skin is going to become! This type of lotion is for experienced tanners only as skin “tingles”, giving you a burning sensation and redness approximately 1-2 hours after tanning. Tingles are best to use when you have reached your tanning plateau and not getting any darker with your typical lotion.
