Question 1

How long does Duac take to work?

Accepted Answer

Most people start seeing improvement within 2–5 weeks. Use it consistently once daily for up to 12 weeks; stopping early may allow acne to return.

Question 2

Can I use other acne products with Duac?

Accepted Answer

Avoid using medicated soaps, abrasive cleansers, or other topical acne treatments containing tretinoin, isotretinoin, or erythromycin, as they may increase irritation. If needed, use them at different times of the day.

Question 3

Does Duac cause skin bleaching or stain clothes?

Accepted Answer

Yes, benzoyl peroxide can bleach hair, coloured fabrics (towels, bed linen, clothing), and carpets. Avoid contact with such materials until the gel is completely dry.

Question 4

What should I do if I experience severe redness or peeling?

Accepted Answer

Mild irritation is common in the first weeks. If severe, reduce application frequency to every other day, use an oil‑free moisturiser, or pause treatment for a few days. See your doctor if irritation persists.

Question 5

Can I use Duac if I am pregnant or breastfeeding?

Accepted Answer

Limited data exist. Your doctor will weigh the benefits against potential risks. Avoid applying to the breast area if breastfeeding. Consult your GP before use.
