Do DHA solutions have a shelf life?
Yes they do. The DHA molecule will break down over time although this can be slowed through proper storage. We have talked with our supplier of DHA about stablization of the molecule. The response was that it is possible but it would cease to work as a sunless tanner. As such, it unfortunately something we will need to live with. Ongoing exposure to high temperatures (over 80), light or frequent exposure to air reduces shelf life. We recommend to our clients to purchase for needs in the next four months to ensure the best results for their clients. Some solutions hold up better than others. It is quite possible that a solution could be fine at 12 months but this would be the exception.
