Yes, we ship worldwide. As soon as you choose your country at the checkout step, the available carriers, their delivery times and prices are displayed. Every parcel is tracked.

Orders are dispatched within 24 to 48 business hours. Then allow, with standard shipping, 7 to 12 business days in France, 8 to 14 days in Europe and 10 to 21 days for the rest of the world. The express option (DHL, Chronopost) brings this down to 5–12 days depending on the destination.

For deliveries outside the European Union, customs duties or import taxes may be charged by the carrier on receipt. They depend on your country and are not included in our prices.

With retinoids, the rule is to start low and go up slowly. If you have never used one, tretinoin 0.025% is the usual starting point. A healthcare professional remains best placed to guide you.

No for retinoids (tretinoin, tazarotene), hydroquinone and estriol: they are contraindicated. For azelaic acid, ask your doctor or midwife.

Yes. Orders are sent in a plain parcel, with no mention of the contents or the shop's name on the outside. The actual contents are, however, declared on customs documents, as required by law.

For hygiene and safety reasons, opened or unsealed products cannot be returned or exchanged. An unopened product can be returned within 14 days of receipt: write to us to arrange the return.
