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.

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.

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.

Dry and dull skin with small pimple-like bumps can occur because of dehydration, damaged skin barrier, clogged pores, harsh soaps, weather changes, poor sleep, stress or improper skincare products. Using strong acne creams on already dry skin may sometimes worsen irritation, roughness and tiny bumps, instead of improving them. A mild skincare routine may gradually improve skin texture. Using a mild face cleanser, regular moisturiser, and sunscreen may help restore the skin barrier and reduce dryness. Creams containing ceramides, hyaluronic acid, or gentle niacinamide may help improve hydration and skin texture in some people. Avoid excessive scrubbing, hot water, fairness creams, and repeated face washing because these may further damage dry skin and increase irritation. Drinking enough water, sleeping well, eating fruits and vegetables and lowering stress may also naturally support healthier skin. If the bumps are related to allergies, fungal irritation or acne, treatment may differ depending on the exact cause. Consult a doctor if the bumps become painful or itchy, spread further, or if dryness and dullness continue to worsen despite proper skincare and hydration.

For acne spots and pigmentation, creams that contain ingredients like azelaic acid, niacinamide, or glycolic acid can be helpful. These help fade dark marks and even out skin tone while also addressing breakouts. Start with a gentle, dermatologist?recommended product and use sunscreen daily, as pigmentation can worsen with sun exposure. If the spots are stubborn or severe, seeing a dermatologist for stronger prescription options will give better and faster results.
