This is a prescription medicine for short-to-medium term use. Avoid sun exposure and always apply a broad-spectrum sunscreen during the day, as the skin becomes more sensitive to sunlight. Do not use during pregnancy or breastfeeding (tretinoin is not safe in pregnancy). Avoid the eyes, lips and mucous membranes. May cause redness, peeling, dryness or irritation. Reduce frequency or stop if severe. Do not use on large body areas or for prolonged periods without medical review, as long-term hydroquinone use can cause skin darkening (ochronosis). Store in a cool, dry place. This product information is for general guidance only and does not replace professional medical advice. Always consult a qualified healthcare provider before starting any new medication or supplement. Keep all medicines out of reach of children.
