Aziderm 10% GelGel is a high‑concentration topical medication used for certain skin conditions. It is best started under medical supervision, because not every skin type or problem requires this strength, and sometimes a lower concentration or a different treatment is more suitable. Using it without guidance may irritate or may not address the underlying issue effectively. The right step is to discuss your symptoms with a dermatologist or GP, who can confirm whether this GelGel is appropriate for you and advise on safe use.

Both Azelaic acid and Niacinamide are good choices for oily, acne-prone skin with pigmentation, but they serve different purposes. Azelaic acid is usually more effective for treating acne and fading post-acne dark marks, as it helps reduce inflammation and slows excess pigment production. Niacinamide is better for controlling excess oil, strengthening the skin barrier, and gradually improving uneven skin tone. In many cases, they can be safely used together when introduced gradually, as this combination can improve both acne control and skin tone.

Pigmentation that develops during or after antibiotic use can have several causes, including drug-induced pigmentation, post-inflammatory hyperpigmentation, or sun-related pigmentation. Since you have been using tretinoin 0.05%, sunscreen, a moisturiser, and vitamin C serum consistently for 6 months with only partial improvement, it is advisable to consult a dermatologist for a thorough skin evaluation. Different types of pigmentation can look similar but often require different treatment approaches. A dermatologist can determine the underlying cause and recommend the most appropriate treatment, which may include prescription depigmenting agents, chemical peels, laser procedures, or adjustments to your current skincare regimen if needed. Continue using broad-spectrum SPF 50 sunscreen daily, as sun protection is essential for preventing further darkening and supporting treatment outcomes.

Both Aziderm 10% Gel and Sebogel can be useful for oily, acne-prone skin with pigmentation, but they work in slightly different ways. Aziderm 10% Gel contains azelaic acid, which helps reduce acne-causing bacteria and calms inflammation. Sebogel contains salicylic acid, niacinamide, and hydrating ingredients that help control excess oil and unclog pores effectively. Aziderm is usually more effective at gradually fading dark spots after acne, while Sebogel is more helpful for very oily skin with blackheads and frequent breakouts. In some cases, dermatologists may advise using both at different times of the day, depending on your skin sensitivity and the severity of your acne.

To treat pimples along with dry, rough, and dull skin, it is important to follow a gentle skincare routine that controls acne without increasing dryness. Use a mild hydrating cleanser instead of harsh or foaming face washes. Doctors often recommend Azelaic Acid cream or gel, as it helps reduce pimples, improve skin texture, and brighten dull skin while being gentler than many other acne treatments. Use a non-comedogenic moisturizer containing ceramides or hyaluronic acid to repair the skin barrier and reduce roughness. Apply a broad-spectrum sunscreen with SPF 30 or higher daily to prevent dark spots and skin damage. Avoid harsh scrubs or over-washing the face. If your acne does not improve within 4 weeks or becomes severe, please consult a dermatologist.

It sounds like you are experiencing Post-Inflammatory Hyperpigmentation (PIH), which is a common and treatable skin reaction after microneedling. Please don't worry, as this is usually temporary. To help fade these patches, daily sun protection is crucial; use a broad-spectrum sunscreen with SPF 30 or higher. You can apply gentle creams containing active generic ingredients like azelaic acid, kojic acid, vitamin C, or niacinamide, which help lighten dark spots. Avoid harsh scrubs or chemical peels for now. I highly recommend consulting a dermatologist to get a personalized prescription, which may include stronger options like topical hydroquinone or retinoids.
