What Does Vinegar Do to a Sunburn and Is It Safe?

Sunburn is a common skin reaction from overexposure to ultraviolet (UV) radiation, causing redness, pain, and discomfort. Many turn to home remedies, with vinegar, particularly apple cider vinegar, often discussed. This article explores vinegar’s purported effects on sunburned skin, safe application methods, and alternative remedies.

Understanding Vinegar’s Effect on Sunburn

Vinegar, specifically apple cider vinegar (ACV), contains acetic acid. Some believe it reduces inflammation and pain associated with sunburn. Anecdotal accounts suggest its acidic nature might help restore the skin’s pH balance. Acetic acid is also thought to possess antibacterial properties, potentially preventing infection. Its astringent qualities are suggested to tighten skin and minimize peeling.

Despite these beliefs, robust scientific evidence for vinegar’s efficacy in sunburn relief is largely lacking; most claims are anecdotal. Many dermatologists caution against its use. Vinegar has a low pH (2-3), which can be harsh on damaged skin. Applying an acidic substance to irritated skin might disrupt the skin barrier, increasing pain, dryness, and slowing healing. Improper use or insufficient dilution can lead to irritation or chemical burns, worsening the sunburn.

Using Vinegar Safely for Sunburn

If considering vinegar for sunburn, proper dilution is important to minimize irritation. Traditional methods suggest diluting vinegar with an equal part water or adding about one cup of apple cider vinegar to a cool bath. This diluted solution can be applied by soaking a clean, chilled cloth and gently placing it on the sunburned area for 10 to 15 minutes.

Another method involves adding diluted apple cider vinegar to a cool bath, soaking for 15 to 20 minutes for widespread burns. Some also mist a diluted solution onto mildly sunburned skin using a spray bottle. Always perform a patch test on a small, unaffected area first. Never apply vinegar to broken skin, blisters, or severe burns, as its acidity can exacerbate damage, increase pain, and elevate infection risk.

Alternative Sunburn Remedies

Other remedies offer more widely accepted relief for sunburn discomfort. Apply cool compresses, such as a towel dampened with cool tap water, or take frequent cool baths or showers to reduce skin temperature and inflammation. After cooling, gently pat skin dry, leaving some moisture, then apply a soothing moisturizer.

Aloe vera is a popular, effective choice, known for its cooling, hydrating, and anti-inflammatory properties. Use pure aloe vera gel or products with high aloe concentration, free of irritants like fragrances or alcohol. Drink extra water to counteract fluid loss and prevent dehydration. Over-the-counter pain relievers such as ibuprofen or acetaminophen can manage pain and reduce inflammation. Avoid products with petroleum, which traps heat, or “-caine” ingredients like benzocaine, as these may irritate skin or cause allergic reactions.
