Dear OncoLink "Ask The Experts,"
I am wondering how long the SPF value lasts in the tube of sunscreen! I do tend to save it from year to year. Thank you.
Carolyn Vachani RN, MSN, AOCN, OncoLink's Nurse Educator, responds:
Look on the bottle for an expiration date and don’t use after that. The FDA requires that the product be stable at the strength stated on the bottle for three years- but can you ever know how long they were on the shelf at the store? So, go with an expiration date.
