How does apple cider vinegar help in treating acne, and what is the best way to apply it?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Apple cider vinegar (ACV) may help treat acne thanks to its antibacterial properties and acetic acid content, which can reduce acne-causing bacteria and balance skin pH. To use it safely, dilute one part ACV with three to four parts water, apply gently to the skin with a cotton pad, and rinse after a few minutes to avoid irritation.

Because acne can have many underlying causes—hormonal shifts, diet, stress, or skin conditions that mimic acne—home remedies alone may not resolve it. Take a free, instant, online symptom check to better understand what's driving your breakouts and confidently plan your next steps.

Explanation

Apple cider vinegar (ACV) is often used for acne treatment because it contains acetic acid, which has antibacterial properties. This means it can help kill bacteria that might cause acne. The vinegar's acidity can also help balance the skin's pH, potentially reducing oiliness and preventing further breakouts.

How to Apply Apple Cider Vinegar:

Dilute the Vinegar: Mix one part apple cider vinegar with three parts water. This helps prevent irritation, as vinegar is very strong when undiluted.
Apply to Skin: Use a cotton ball to gently apply the mixture to the affected areas of the skin.
Leave it On: Let it sit on your skin for about 5 to 20 seconds, then rinse it off with water.
Moisturize: After rinsing, apply a moisturizer to keep your skin hydrated.

It's important to test the diluted vinegar on a small area first to ensure it doesn't cause irritation. Regular use may help improve the appearance of acne over time.
