When it comes to acne treatment and skin care, there are several common questions that arise, especially for those who are beginning their journey with dermatological treatments. Here’s a comprehensive response to your inquiries based on current medical knowledge and practices.

1. Should I stop using skincare products during acne treatment?
It is not necessary to completely stop using skincare products while treating acne, but you should be cautious about the types of products you use. During acne treatment, especially with medications like topical retinoids (such as A acid), it is advisable to avoid products that can irritate the skin further. This includes products with strong exfoliants, alcohol, or fragrances. Instead, focus on gentle, non-comedogenic moisturizers and cleansers that can help maintain skin hydration without exacerbating acne. Always consult your dermatologist for personalized advice on which products to continue or discontinue.

2. Do I still need to apply sunscreen the day after using A acid?
Yes, applying sunscreen is crucial, even the day after using A acid. Topical retinoids can increase your skin's sensitivity to sunlight, making it more susceptible to sunburn and damage. It is recommended to use a broad-spectrum sunscreen with an SPF of at least 30 every morning, regardless of whether you have used A acid the night before. This helps protect your skin from UV rays and prevents further pigmentation issues or skin damage.

3. Can food allergies cause acne or folliculitis?
While food allergies are not a direct cause of acne, certain food sensitivities can trigger inflammatory responses in some individuals, potentially leading to skin issues, including acne. Foods high in sugar, dairy, and certain fats may exacerbate acne in some people. Folliculitis, which is the inflammation of hair follicles, can also be influenced by dietary factors, though it is more commonly associated with bacterial infections or irritation. Keeping a food diary and noting any skin reactions can help identify potential triggers, and discussing these with your dermatologist can provide further insights.

4. What should I use for post-acne hyperpigmentation: glycolic acid or whitening treatments?
For treating post-acne hyperpigmentation, both glycolic acid and whitening treatments can be effective, but they work in different ways. Glycolic acid, an alpha hydroxy acid (AHA), helps exfoliate the skin and can promote cell turnover, which may reduce the appearance of dark spots over time. On the other hand, whitening agents like hydroquinone or vitamin C can help lighten existing pigmentation. The choice between these options may depend on your skin type, the severity of the pigmentation, and any other treatments you are currently using. It is advisable to consult your dermatologist to determine the best course of action tailored to your skin's needs.

In summary, managing acne and its aftermath requires a careful approach to skincare. It is essential to maintain a consistent routine that includes gentle cleansing, moisturizing, and sun protection. Be mindful of the products you choose, and don’t hesitate to reach out to your dermatologist with any concerns or questions. They can provide guidance tailored to your specific skin type and condition, ensuring you achieve the best possible results in your acne treatment journey.
