QUESTION:

Can I use the same self-tanner I bought last year?

ANSWER:

“As long as you store your self-tanner at room temperature, it should have a 12 month life span.” says cosmetic chemist and founder of BeautyStat.com, Ron Robinson. While DHA (the ingredient in self-tanners that darkens the skin) isn’t harmful after that time, it definitely becomes less effective, upping the chance for it to leave streaks or cast an unnatural, orangish skin tone. If it’s been less than a year but your self-tanner has a strange smell or different color than when you bought it, toss it.
