7. Chemical Sunscreens

Chemical Sunscreens

Sunscreens that contain chemicals such as avobenzone, oxybenzone, ecamsule, octocrylene, octinoxate, and homosalate work differently than mineral-based sunblocks. According to Piedmont Healthcare, these substances prevent sunburn by absorbing harmful UV rays. Next, these chemicals transform the UV rays into heat, which the body discharges back into the environment. Sunscreens are designed to prevent diseases, including sunburn and skin cancer. Therefore, the FDA regulates them to ensure that they perform their intended functions without causing harm to those who use them.

6. Absorption of Chemicals

Chemical Component

Recently, a study by the Center for Drug Evaluation and Research found that the chemical components of common sunscreen products were absorbed into the bloodstream of individuals who use them. The results of this study have prompted the FDA to recommend further studies to determine whether blood levels of these chemicals may cause harm to the consumers using them. According to the American Academy of Dermatology, these studies will help uncover more information about the levels of sunscreen chemicals absorbed by the skin. These studies will also help determine whether the absorption of these chemicals has a negative effect on health.

5. Contact Allergies

Contact Allergies

Some individuals may experience an allergic rash when using sunscreens. In these individuals, the chemicals in the sunscreen react with the sun’s rays to cause an allergic reaction known as photocontact dermatitis. This condition may appear as red, itchy, raised bumps on the skin. According to the American College of Allergy, Asthma, and Immunology, oxybenzone is an active ingredient frequently used in sunscreen. Oxybenzone is also one of the common causes of photocontact dermatitis. Individuals who experience this reaction may find that sunblocks containing zinc oxide or titanium dioxide will provide UV protection without triggering an allergic reaction.
