At QNET, we highly prioritize the safety of our customers, but it is important to note that different things can cause different allergic reactions. Our skin care products do not contain the most common allergens; however, natural extracts and essential oils may still cause various skin reactions. Note that this does not signify poor quality. The body can have many possible allergic reactions to different components. It is always recommended to perform a patch test before using any new skin care product, especially if you have sensitive skin or known allergies. This precaution can help prevent any adverse reactions and ensure a safe experience with our products.
