Should You Add Apple Cider Vinegar to Your Skin-Care Routine?

 

The popular home remedy may have benefits for certain conditions, but experts warn it can cause serious reactions.

Using pantry staples for skincare, from avocado facials to honey scrubs, has long been a popular practice. Apple cider vinegar (ACV), another superfood ingredient, has also gained attention for its potential skincare benefits. Many people consider using ACV to address acne or other skin conditions like eczema, psoriasis, or rosacea, thanks to its reputation for healing wounds and reducing blood sugar levels in individuals with type 2 diabetes, as suggested by some research.

However, it's important to note that the purported benefits of ACV for skincare lack strong scientific evidence. Harvard Health Publishing highlights the absence of long-term randomized controlled trials investigating ACV's effects on humans. Additionally, University of Chicago Medicine emphasizes that despite online claims, ACV does not cure cancer.

While some components of ACV may offer potential benefits for skin health, experts remain cautious about its use, whether consumed orally or applied topically. In this article, we'll delve into the potential benefits and risks of using apple cider vinegar for skincare.

Could Apple Cider Vinegar Enhance Your Skin's Appearance?

Many individuals ponder whether incorporating apple cider vinegar (ACV) into their skincare routine could yield positive results for their complexion. While some research suggests that ACV may possess antifungal and antibacterial properties, there remains a scarcity of scientific evidence regarding its efficacy in improving skin appearance, as noted by Dr. Melissa Piliang, a dermatologist at the Cleveland Clinic. Dr. Piliang emphasizes the need for robust scientific backing for the purported skincare benefits of ACV, cautioning against potential adverse effects. Nevertheless, she acknowledges that ACV might offer assistance with certain skin conditions if used judiciously and under the guidance of a dermatologist.

ACV contains components that hold potential for enhancing skin health. One such component is acetic acid, known for its antifungal and antimicrobial properties. When applied topically, acetic acid aids in eliminating bacteria associated with infections or skin issues such as acne, rosacea, and chronic scalp conditions like seborrheic dermatitis and eczema.

Additionally, ACV contains citric acid, a member of the alpha hydroxy acid (AHA) family. AHAs are recognized for their ability to promote skin cell turnover and diminish wrinkles and age spots.

Although ACV boasts higher concentrations of acetic acid and citric acid, similar acids can be found in other vinegar varieties. According to Dr. Abigail H. Waldman, a dermatologist at Brigham and Women’s Hospital in Boston, white vinegar may offer comparable benefits for addressing skin conditions as ACV. Dr. Waldman highlights the long-standing use of vinegar soaks by medical professionals, suggesting that while ACV may contain more citric acid, some of its effects may be exaggerated.

Diluting Apple Cider Vinegar for Safe Use

Experts caution against applying pure apple cider vinegar (ACV) directly to the skin in skincare routines due to its acidic nature, which can lead to chemical burns and irritation, as reported in case studies.

Dr. Patricia Farris, a dermatologist in Metairie, Louisiana, and a clinical associate professor at the Tulane University School of Medicine in New Orleans, highlights the risk of skin irritation and burns associated with the direct application of ACV. She advises patients against using this home remedy due to safety concerns.

For addressing skin infections, Dr. Waldman recommends diluting ACV by mixing 1 tablespoon of ACV with 1 cup of water. While there are varying recommendations for dilution concentrations, starting with this ratio is advisable to assess tolerance levels.

Dr. Waldman underscores the importance of finding a balance between concentration and effectiveness. While higher concentrations of ACV may offer enhanced benefits due to increased levels of acetic and citric acid, they also pose a higher risk of skin irritation. Therefore, using ACV in its concentrated form is not recommended to avoid adverse effects.

The Potential of Apple Cider Vinegar in Treating Skin Conditions

Expert opinions regarding the efficacy of apple cider vinegar (ACV) for skin conditions vary. While some have heard of success stories, others caution against its use due to potential adverse reactions. Dr. Waldman acknowledges that ACV may offer relief for mild conditions but cautions against relying on it solely for more severe cases.

When using diluted apple cider vinegar on the skin, it's crucial to understand the basics. The outer layer of the skin, known as the epidermis, acts as a protective barrier. Using harsh products can disrupt this barrier, leading to dryness and increased susceptibility to irritants. ACV's slightly acidic pH can complement the skin's natural acidity, particularly for those with dry skin, helping maintain the lipid layer and barrier function.

Regarding acne treatment, keratin buildup within pores contributes to acne formation. AHAs, such as citric acid found in ACV, help dissolve keratin, facilitating pore drainage and potentially improving acne appearance. However, the lack of robust studies hinders the validation of ACV's effectiveness in this regard.

Using ACV alongside other anti-acne products may exacerbate skin irritation and compromise the skin barrier. Dr. Waldman emphasizes the importance of individualized skincare routines, considering factors like skin type and tolerance levels. While teens with oily skin and acne may tolerate ACV better due to their skin's resilience, those with sensitive or dry skin should exercise caution.

In conclusion, while ACV shows promise in addressing certain skin concerns, its use should be approached with caution, especially when dealing with severe conditions or alongside other skincare products. Individualized care and close monitoring are essential to ensure optimal results and minimize potential adverse effects.

Acne

Acne arises when keratin, the primary protein in the skin, accumulates within a pore, forming a plug known as a blackhead or a whitehead. Alpha hydroxy acids (AHAs) like citric acid aid in dissolving keratin, allowing the pore to open up and drain, thus reducing the appearance of pores and improving acne. Similar effects are observed with retinoids and benzoyl peroxide.

While apple cider vinegar (ACV) contains AHAs and theoretically holds potential for acne treatment, conclusive studies are lacking, according to Piliang. Combining ACV with existing anti-acne washes or treatments may exacerbate skin irritation, leading to dryness and peeling, potentially compromising the skin barrier.

Using ACV without dilution could disrupt the skin's protective barrier, allowing external irritants and bacteria to penetrate. Skin tolerance varies among individuals, with oily skin generally having a higher tolerance for acidic products compared to sensitive, dry skin. There is no one-size-fits-all recommendation for skincare routines.

Teenagers with oily skin and acne may tolerate ACV better due to their skin's resilience and faster oil replenishment. Conversely, older adults with drier skin are more susceptible to irritation. Thus, caution is advised when incorporating ACV into skincare routines, especially for individuals with sensitive or dry skin.

Eczema or Psoriasis

For individuals with psoriasis or eczema, caution is advised when considering the use of apple cider vinegar (ACV). According to Piliang, applying ACV to areas of the skin that are already broken, fissured, or bleeding can cause significant discomfort and a burning sensation.

When dealing with eczema, where the skin's protective barrier is compromised, there is an increased risk of bacterial or fungal infections. Waldman suggests that using diluted ACV may help eliminate bacteria, potentially reducing the risk of infection.

While Waldman has observed cases where ACV appeared to improve psoriasis symptoms, the mechanism behind its effectiveness remains unclear. However, she notes that ACV may offer relief for conditions like seborrheic dermatitis, characterized by a scaly scalp and greasy, thick pink scales on the face. This condition is believed to be linked to the skin's response to fungal and bacterial presence, making a diluted vinegar soak a potential remedy.

Rosacea

For individuals dealing with rosacea, exercising caution when considering the use of apple cider vinegar (ACV) is crucial. Piliang emphasizes that individuals with rosacea typically have highly sensitive skin with a compromised outer layer, making them prone to adverse reactions.

Waldman echoes this sentiment, advising against the use of ACV for rosacea due to the multifactorial nature of the condition. Rosacea can result from various triggers, including normal skin organisms, sun exposure, spicy food, coffee, and irritating skincare products.

"While ACV may potentially alleviate inflammation associated with rosacea, its use should be approached with extreme caution," says Waldman. "Improper application, such as using undiluted ACV or applying it on particularly sensitive skin, can exacerbate symptoms rather than provide relief."

Skin Infections

Waldman has observed patients effectively utilizing vinegar soaks to address chronic or acute local skin infections, such as fungal infections like athlete’s foot and paronychia (infection around the fingernails). Vinegar soaks have shown particular efficacy in treating toenail infections caused by pseudomonas bacteria, which manifest as greenish discoloration of the nails, also known as chloronychia, as noted by the American Osteopathic College of Dermatology.

When assessing skincare products containing apple cider vinegar, Waldman cautions that the concentration of ACV may be unclear. Instead, she advises seeking products with acetic acid, citric acid, or other AHAs, or creating a homemade toner using 1 tablespoon of organic ACV in 1 cup of water. This ensures efficacy without unnecessary expenditure on branding.

Although medical research has yet to fully endorse the external use of apple cider vinegar for specific skin conditions, ongoing exploration is underway to determine its potential for skin and cosmetic benefits in clinical settings. A study has suggested that topical application of apple cider vinegar may enhance the effectiveness of varicose vein treatments, improving both pain levels and cosmetic appearance.

How to Determine If Apple Cider Vinegar Isn't Improving Your Skin Condition

1. Persistent Symptoms: If you continue to experience the same symptoms of your skin condition despite regular use of apple cider vinegar, it may indicate that it's not providing the desired relief or improvement.

2. Worsening of Symptoms: Pay attention to any worsening of your skin condition after using apple cider vinegar. If you notice increased redness, irritation, or discomfort, it could be a sign that ACV is exacerbating rather than alleviating your skin issue.

3. No Change in Appearance: Lack of improvement in the appearance of your skin condition over time despite consistent application of apple cider vinegar suggests that it may not be effective for your particular condition.

4. Development of New Symptoms: Be wary of any new symptoms or side effects that arise after using apple cider vinegar on your skin. These could indicate an adverse reaction to ACV and warrant discontinuation of its use.

5. Consultation with a Dermatologist: If you're unsure whether apple cider vinegar is helping your skin condition, or if you experience any concerning symptoms, it's advisable to consult a dermatologist. They can provide professional insight and guidance tailored to your specific needs.

6. I understand the desire for alternative treatments, but there are instances where seeking medical attention is necessary," she says. "Obtaining an opinion from an outside expert can provide reassurance that everything is normal or indicate if further evaluation is needed.
