I use a cream that is basically excipient (I think mainly lanolin) and 0.03% vitamin A (very efficient in promoting wound healing).
You could have this mixed up by a pharmacist. Just that the absence of a preservative would mean small quantities and toss soon. Or keep in the fridge.

I think the parabens are overrated.

A recent review of the available data has concluded "it is biologically implausible that parabens could increase the risk of any estrogen-mediated endpoint, including effects on the male reproductive tract or breast cancer" and that "worst-case daily exposure to parabens would present substantially less risk relative to exposure to naturally occurring endocrine active chemicals (EACs) in the diet such as the phytoestrogen daidzein."

In addition, the American Cancer Society has concluded that there is no good scientific evidence to support a claim that use of cosmetics such as antiperspirants increase an individual's risk of developing breast cancer.
