Introduction
Under normal circumstances, apple cider vinegar is not recommended for topical application on wounds, as improper use may adversely affect wound healing. In daily life, if a wound occurs, first clean the skin around the wound, then treat it with professional disinfecting products, and bandage when necessary to avoid exposing the wound to a contaminated environment. At the same time, keep the wound dry and clean, and avoid applying non-medical products topically at random.
Generally, apple cider vinegar is not recommended for topical application on wounds, as its indiscriminate use may adversely affect wound recovery. A detailed analysis is as follows:
Apple cider vinegar contains acetic acid, which has an irritating nature, while the skin and mucous membranes around wounds are typically delicate. Direct topical application of apple cider vinegar on wounds may irritate the wound surface, potentially causing significant stinging sensations. It may also damage the normal mucosal barrier around the wound, worsening local symptoms such as redness, swelling, and warmth, and even interfering with the normal healing process. Additionally, commercially available apple cider vinegar might contain added sugars, colorants, and other ingredients. When applied directly to wounds, these substances may create an environment conducive to bacterial growth, increasing the risk of wound infection and delaying healing.
In daily life, when wounds occur, it is important to first clean the skin surrounding the wound and then treat it with professional disinfectants. Dressing may be needed to prevent exposure to contaminated environments. At the same time, keeping the wound dry and clean, and avoiding the arbitrary use of non-medical products for topical application, will better promote wound healing and maintain skin health.
