Is tanning indoors safer than outdoors in the sun?
Indoor tanning is done in a controlled environment, which allows you to slowly build a tan, to develop pigmentation and increase your natural SPF, thus providing a safer environment. The external factors of tanning in the sun, such as time of year and day, altitude, cloud coverage, pollutants, reflective surfaces, etc. are harder to control or predict, which increases your risk of overexposure.
