Daily Moisturizers and SPF

 

Daily moisturizers that claim to provide UV protection may not provide protection from UVA rays.

Are we getting enough sun protection from just applying a daily moisturizer in the morning?  Manufacturers are increasingly adding UV filters to skin care products, however, a recent study published in the Archives of Dermatology suggests that these products do not provide necessary protection against the UVA aging rays  (UVB are burning rays).

Researchers chose 29 top selling day creams with claims of broad spectrum UV using sales volumes from the US website Amazon.com. They looked for the presence of chemical UVA filters and zinc oxide in the products.

Although actual product names are not disclosed, according to the study, six of the 29 products contained no active ingredients that provide UVA protection and seven of the remaining 23 contained zinc oxide, but only 3 contained levels greater than 5 per cent, which the team said was required to provide ‘adequate’ UVA protection. Sixteen products did contain chemical filters, but only 3 had adequate concentrations of a key ingredient necessary to stabilize the filters, which according to the researchers, is otherwise unstable on contact with UV rays.

The researchers concluded that many day creams do not offer long wave UVA protection.
