Can I use acids on a large inflamed pustule?


Hello, doctor.
I would like to ask about my condition, which involves large pustular acne.
1.
If I do not pop them, can I use products containing alpha hydroxy acids (AHAs) like mandelic acid? Will it help improve my condition? 2.
If I do pop them, can I still use products with AHAs? Will it worsen my condition, or should I only apply antibiotic ointment at that time?

Chen, 20~29 year old female. Ask Date: 2022/03/21

When dealing with large inflammatory pimples, such as cystic acne or large pustules, the choice of treatment is crucial to avoid exacerbating the condition. Here’s a detailed response to your questions regarding the use of acid products, specifically mandelic acid, in such cases.

1. Using Mandelic Acid on Non-Extracted Pimples: If you have large inflammatory pimples that you have not attempted to extract, using mandelic acid can be beneficial. Mandelic acid is an alpha hydroxy acid (AHA) derived from almonds, known for its gentle exfoliating properties. It can help to improve skin texture, reduce inflammation, and promote cell turnover without being overly harsh on the skin. This can lead to a reduction in the size and redness of the pimples over time. However, it is essential to use it as directed and to monitor your skin's response. If you notice increased irritation or sensitivity, it may be best to discontinue use.

2. Using Mandelic Acid After Extraction: If you have already attempted to extract the pimples, caution is advised. While mandelic acid can help with exfoliation and may prevent future breakouts, applying it on freshly extracted pimples can lead to irritation and potentially worsen the inflammation. After extraction, the skin barrier is compromised, making it more susceptible to irritation from active ingredients. In this case, it may be more prudent to focus on soothing and healing the skin. Using a gentle, non-comedogenic moisturizer and possibly an antibiotic ointment may be more appropriate to prevent infection and promote healing.

3. Antibiotic Ointments: If you have extracted the pimples, applying a topical antibiotic ointment can help prevent bacterial infection and reduce inflammation. Common options include clindamycin or erythromycin, which can be effective against acne-causing bacteria. These should be used as directed by your healthcare provider.

4. General Recommendations: It’s essential to approach the treatment of large inflammatory pimples with care. Here are some general tips:
- Avoid Picking or Squeezing: This can lead to scarring and further inflammation.

- Use Non-Comedogenic Products: Ensure that any skincare products you use are labeled non-comedogenic to avoid clogging pores.

- Consult a Dermatologist: If your acne is severe or persistent, it may be beneficial to consult a dermatologist. They can provide tailored advice and may recommend prescription treatments, such as topical retinoids or oral medications, depending on the severity of your condition.

In summary, mandelic acid can be used on large inflammatory pimples that have not been extracted, but caution is advised if the pimples have been manipulated. In such cases, focusing on healing and preventing infection with antibiotic ointments may be the best course of action. Always listen to your skin and consult with a healthcare professional if you have any concerns about your treatment plan.
