The compounds present in their formulation are subject to degradation and when stored for longer than indicated on the package may favor the appearance of microorganisms such as fungi and bacteria. These altered substances can cause dermatitis, swelling, blistering and redness, as well as injury to the cornea if used near the eyes.
These compounds may also undergo oxidation due to contact with air, temperature and light. Once oxidized, the molecules of the product transform and become irritating and allergenic.
The manufacturer himself no longer guarantees the safety of the sunscreen, if it is used after the deadline.
