Sunscreen or sunblock protects our skin from by absorbing or reflecting the UV rays of the sun. However, the chemicals used in the sunscreen may cause sunscreen allergy in a few people. This reaction takes place when our body mistakenly identifies some chemicals in the sunscreen as harmful and reacts to it.
In some cases, sunscreen allergy develops only when you are exposed to the sun. These reactions are known as photoallergic reactions. Photoallergic reactions are caused when the sunscreen reacts with the UV rays, resulting in an allergic reaction.
