Alpha hydroxy acid (AHA)
I would like to ask! I have pimples all over my body! I have seen many dermatologists without any effective results! Sometimes I also get them on my neck! Why is that? One dermatologist suggested that I try glycolic acid lotion!!! But I have sensitive skin and allergies! Is it safe for me to use? If so, where can I buy it? Which brand should I choose? However, I am mostly allergic to dust mites!!!

Hello, Pudding: Regarding the issue you mentioned, it seems to be a case of folliculitis.
The questions of whether it itches or hurts are commonly asked! If the folliculitis is uniform and slightly itchy, you might consider seborrheic folliculitis, which can be caused by allergic predisposition or medication factors such as long-term use of corticosteroids or antibiotics.
If there is significant pain, you should consider bacterial folliculitis, which requires a bacterial culture for accurate treatment.
Alpha hydroxy acids (AHAs) can regulate keratinocyte metabolism; at low concentrations, they can help open pores and bring superficial acne to the surface, which is often the first noticeable effect.
If the concentration is increased, it can improve skin elasticity and luminosity and promote new collagen production.
For sensitive skin, it is advisable to start with a 10% concentration and gradually increase it.
After an AHA treatment, it is important to apply ice packs and use sunscreen and moisturizer to prevent post-inflammatory hyperpigmentation and dryness that could lead to eczema.
I recommend undergoing treatments at a hospital for safety.
If there are areas of dermatitis, it is best to treat those first before proceeding with any chemical peels to avoid adverse effects such as the recurrence of conditions like flat warts or viral rashes.

More Info
When it comes to managing acne, especially for individuals with sensitive or allergic skin, the use of Alpha Hydroxy Acids (AHAs) can be a double-edged sword. AHAs, such as glycolic acid and lactic acid, are known for their exfoliating properties, which can help in unclogging pores and reducing acne. However, for those with allergic skin or a history of sensitivity, caution is essential.
Firstly, it’s important to understand that AHAs work by loosening the bonds between dead skin cells, allowing them to be shed more easily. This process can help prevent clogged pores, which is a common cause of acne. Additionally, AHAs can promote cell turnover, leading to fresher, healthier skin over time. However, this exfoliation can also lead to increased sensitivity, redness, and irritation, particularly in individuals with allergic skin or conditions like eczema or rosacea.
Given your history of allergies, it is crucial to approach the use of AHAs with care. Here are some recommendations:
1. Patch Test: Before applying any AHA product to your face or body, conduct a patch test on a small area of skin. This will help you determine if you have any adverse reactions to the product. Wait 24-48 hours to see if any irritation occurs.
2. Choose the Right Product: Look for AHA products that are specifically formulated for sensitive skin. These products often contain lower concentrations of AHAs and are combined with soothing ingredients like aloe vera, chamomile, or hyaluronic acid to minimize irritation. Brands like Paula’s Choice, Neutrogena, and La Roche-Posay offer options that may be suitable for sensitive skin.
3. Start Slowly: If you decide to incorporate an AHA into your skincare routine, start with a low concentration (around 5-10%) and use it only once or twice a week. Gradually increase the frequency as your skin builds tolerance.
4. Moisturize: AHAs can be drying, so it’s essential to follow up with a good moisturizer to maintain hydration. Look for non-comedogenic moisturizers that won’t clog your pores.
5. Sun Protection: AHAs can make your skin more sensitive to the sun, increasing the risk of sunburn. Always apply sunscreen during the day, especially when using AHAs.
6. Consult a Dermatologist: Since you have a history of allergies and have seen multiple dermatologists without success, it may be beneficial to consult a dermatologist who specializes in sensitive skin or acne. They can provide personalized recommendations and may suggest alternative treatments, such as topical retinoids or oral medications, that could be more effective for your condition.
7. Consider Other Treatments: If AHAs are not suitable for your skin, there are other options available for treating acne, such as salicylic acid, benzoyl peroxide, or even prescription medications. Your dermatologist can help you explore these alternatives.
In summary, while AHAs can be beneficial for acne treatment, they may not be suitable for everyone, especially those with allergic skin. Always prioritize your skin's health and comfort by starting slowly, choosing the right products, and consulting with a healthcare professional. Your journey to clearer skin may require some trial and error, but with the right approach, you can find a solution that works for you.
