Apple Cider Vinegar Is the Surprising DIY Acne Trick You're Missing

How does apple cider vinegar help with acne?

Although there has been no specific research on apple cider vinegar for acne, there are research-backed properties of ACV that show it may be beneficial in improving breakouts, says Dr. Hayag. “ACV contains acetic, citric, lactic, and succinic acids, all of which have been shown to kill acne-causing bacteria called Propionibacterium acnes or P. acnes,” she says. Plus, ACV acts sort of like a gentle, at-home chemical peel, helping improve hyperpigmentation, soften acne scars, and lead to overall glowing skin.

“The succinic acid has been shown to decrease inflammation and therefore help with scarring,” says Dr. Hayag. The lactic acid (yes, the same one you know and love from your skincare) can help improve the superficial texture of your skin. It removes the outer layer of your skin, exfoliating dead skin cells and helping healthier skin grow. This can majorly help improve scars, texture, and pigmentation. The other acids, such as malic acid, help balance the skin’s pH level, which is normally 4.5 to 5.5. “This fairly acidic environment helps keep harmful bacteria and contaminants at bay and improves skin barrier function,” adds Dr. Hayag. Sounds great, right? Well, it’s not without its side effects (keep reading).

Are there any side effects?

Those with sensitive skin may find apple cider vinegar for acne too harsh, so first-time users should be cautious. “Since it is very acidic, it can be irritating and can cause burns when directly applied to the skin,” says Dr. Hayag. To minimize irritation, always dilute ACV with water and only leave it on your skin for a short amount of time (like, seconds!). If it burns, wash it off ASAP. Beauty is not pain in this case, and you don’t want to burn your skin causing more issues than what you started with. Dr. Hayag recommends doing a patch test first to see if your skin can tolerate apple cider vinegar as an acne treatment. If it can, there are a few ways you can use it, starting slowly and working up to a more exfoliating treatment.

What skin types does apple cider vinegar work best for?

Not surprisingly, those with oily and acne-prone skin types find ACV works best at minimizing breakouts. Those with sensitive skin might find it too harsh, and those with dry skin might find it too drying. Always follow up an ACV treatment with extra hydration, such as gentle, peptide-enriched moisturizer. Those with oily and acne-prone skin will want to use an oil-free, lightweight moisturizer that’s sure not to clog pores and cause future breakouts.

How should you use apple cider vinegar for acne?

For the best results, Dr. Hayag recommends using “organic apple cider vinegar that contains ‘the mother,’’' the cloudy substance at the bottom of the bottle. It looks a little icky, but this is where the good stuff lives. “This layer contains the enzymes, proteins, and beneficial bacteria that are responsible for ACV’s health benefits,” she says. Though, without preservatives, you’ll want to be extra careful as it’s much more potent.

Dr. Hayag recommends a few ways to use apple cider vinegar. First, as a cleanser, mix a quarter cup of warm water with one tablespoon of apple cider vinegar. If you prefer to use ACV as a toner, start off slowly applying the following solution one to three times per week with a cotton ball: for sensitive skin, use one part apple cider vinegar to five parts water; for moderate acne, use one part apple cider vinegar to four parts water; and for severe acne use one part apple cider vinegar to three parts water. Those with severe acne can try using ACV as both a cleanser and toner.

You can also use ACV as an acne spot treatment, which might be even better for those with dry or sensitive skin, who don’t need to use it all over their face. Apply the diluted solution directly to the pimples to dry them out. Prefer to have an at-home spa day? If you have a facial steamer at home, you can add four tablespoons of ACV to two cups of water and heat the mixture. “Cover your head with a towel and place your face above the hot mixture, being careful to not get in contact with it,” says Dr. Hayag.
