While searching for a remedy for sunburn pain last year, I ran across multiple references to vinegar as an effective method in treating sunburn pain.

  1. Is there any research that validates or invalidates this claim?

  2. If founded, how might vinegar act as a sunburn pain reliever? (for example, capsaicin is thought to cause nerves to be unable to report pain for an extended period of time, due to neurotransmitter depletion.)

    I've used it myself, and it seemed to work. (For obvious reasons, I'm not posting this as an answer.) Commented Aug 22, 2013 at 18:06

    Do not put acid on a sunburn (or on any kind of burn). Depending on the severity of it, you risk opening the door to many infections. Try to cool the burn down instead. Liquid applied on it might evaporate and reduce the temperature, but it does not have to be vinegar. Commented Apr 18, 2017 at 10:11

1 Answer 1


There seems to be indeed not much done for this research on a definitively not patentable solution. Most online sources craving credibility for this claim mention the University of Pittsburgh. Sometimes even "a paper from". But trying to follow that lead I ended up at a page where a nurse tells just her own anecdotal story of how she herself once found great relief from sunburn by using vinegar. One of these websites was kindly transparent enough to directly mention this very weak evidence. But most try to create the false impression of a research level study conducted there to reach this conclusion.

Vinegar as a sunburn treatment is probably in use since shortly after the first Egyptian made it while suffering from being out in the sun too long. Hippocrates and Galen also mention the use of that substance for sunburn related pain and other thermal injury.

Historical evidence aside, some people try now to cash in into combining old knowledge into patentable formulations. This, however, is not backed up by rigorous scientific testing, and may very well backfire.

The effectiveness of vinegar has several important components:

  1. for milder cases the evaporation point is low enough to provide a cooling sensation, directly counteracting the "burn"-part of the condition (higher than using water/wet towels alone).

  2. the moisture might sooth dried out skin that will otherwise or is already cracking

  3. for slightly more severe cases it will also limit the growth of bacterial infections that might profit from such a situation
  4. a small direct reduction in pain might be difficult to be observed from the vinegar alone

This is mostly an answer from a historical viewpoint and by no means any form of medical advice. But using low concentration vinegar on mild sunburns might be quite effective. Although, if other options are available, they might be preferred, since prolomged contact with such acidic material might be an additional irritant.

    The first paragraph is quite condescending. This is not that kind of site. Make this answer more apathetic and I'll remove the down vote.

    What if our forum becomes too apathetic?

    @fredsbend I think it was not condescending enough. Anectodal evidence requires it.

  • @Stian No, it does not. "The community should reject and down-vote disproportionate, mocking behavior towards any opposing ideas or people in the guise of making a VALID argument." Reserve smug and snarky comments for somewhere else.

    @fredsbend I totally agree that towards people asking questions, making arguments and either mistakenly or validly holding opinions contrary to common belief one should certainly not "be a dick". But expressing (reasonable) scorn over an anectodal piece of evidence on the internet is totally within bounds of conveying a message about the uselessness of said piece of evidence.
