BR Skin Reaction Policy 📄
At Loshen & Crem, we want to ensure you have the best possible experience with Biologique Recherche. Before purchasing any Biologique Recherche product, we highly recommend booking a consultation with one of our estheticians. Consultations are available virtually through Google Meet or in person at our Edmonton boutique. An appointment is required.
In the event of a reaction, Biologique Recherche requires photos of the reaction and the product, the lot number found on the product or the bottom of the box, and proof of a consultation with one of our estheticians before they can review the concern.
If you choose to purchase without a consultation and experience a reaction, we will be unable to provide a refund. Our team is always happy to answer your questions and help you select the products best suited to your skin.
