A new article published in the International Journal of Women’s Dermatology discussed that sunscreens may contain varying number of ultraviolet filters (UVFs).

The authors reported that sun protection to prevent skin cancer and aging changes should combine sun avoidance, the use of protective structures and clothing, as well as sunscreen usage. Newer and safer products are needed to help supplement and replace older agents to improve cosmetic acceptability. Certain ingredients are known to cause local toxicities like contact dermatitis or photocontact dermatitis, and should be replaced. Additionally, special considerations for children is warranted and environmental, ecological and human toxicities must be addressed.

This article stated that sunscreen is recommended for infants, aged six months and older, while the best practices for sun safety for younger neonates and infants are direct sun avoidance and the use of lightweight, sun protective clothing. Sunscreens are contraindicated in younger infants as their skin is immature and they have a higher surface-area to body-weight ratio, which poses the risk for greater absorption of chemicals. Although limited, evidence suggests that chemical sunscreens can be absorbed systemically. Therefore, sunscreens should be avoided during pregnancy and breastfeeding, owing to its effects on the fetus—as shown in animal models. In these scenarios, physical blockers are preferred. Furthermore, sunscreens should never be applied too close to the areola by breastfeeding mothers, where they may interfere with suckling.

This article summarized that irritants, allergens, photoallergens, as well as cosmesis are points to consider when advising patients about proper sun protection. The American Academy of Dermatology’s (AAD’s) Practice Safe Sun Program emphasizes upon protection to prevent skin cancer and aging with a combination of sun avoidance, protective structures, clothing, as well as regular use of sunscreen products and newer and safer products with special considerations for children.
