Our products are designed for a wide range of daily beauty routines, but everyone's skin is different. If you have sensitive skin, we recommend checking the product details carefully and doing a small patch test before full use.

Please follow the instructions on the product page or packaging. For skincare items, apply to clean skin and introduce new products gradually, especially if you are using other active products in your routine.

Orders usually require 3-4 business days for processing. Delivery generally takes 5-15 business days for the United States, 7-15 business days for the UK and Europe, and 10-20 business days for other regions.

For hygiene and safety reasons, opened or used beauty products may not be eligible for return unless there is a clear quality issue. Please contact support@trinous.com with your order number and photos if there is a problem.

Stop using the product immediately and rinse the area with water. If irritation continues, consult a healthcare professional. You can also contact us with your order details so our team can assist.
