The expiry date for Mycina H&T (hydroquinone and tretinoin) cream is usually printed on the crimped end of the tube; if only the manufacturing date (12/2023) is available, such creams are generally stable for about 18–24 months, suggesting an approximate expiry between June 2025 and December 2025 if stored properly in a cool, dry place away from sunlight. Still, since tretinoin can degrade with light and air, it is advisable to check with a pharmacist or avoid use if there are any changes in colour, smell, or texture.
