Tanning drops, like many other skincare products, can indeed go bad over time. The shelf life of tanning drops can vary depending on the specific formulation and the preservatives used. It is important to check the expiration date on the packaging or consult the manufacturer's recommendations for the product's shelf life.

Typically, tanning drops can last anywhere from six months to a year if stored properly. However, factors such as exposure to air, sunlight, and high temperatures can accelerate the degradation process. If you notice any changes in the color, texture, or smell of the tanning drops, it is advisable to discard them, as they may have expired or become ineffective.

To maximize the shelf life of your tanning drops, store them in a cool, dry place away from direct sunlight. Additionally, ensure that the bottle is tightly sealed after each use to minimize air exposure. If you have any concerns about the longevity of your tanning drops, it is always best to reach out to the manufacturer for specific guidance.
