Thank you for taking the time to leave a review, it is helpful. We are glad to hear enjoyed using the BioLumin-C Eye Serum and that you would consider incorporating this into your skincare routine. Samples are an excellent way to test a product for skin compatibility but unfortunately, you will not always see the entire results unless you use a product for 2 - 3 weeks.
Thank you for leaving your review, it is helpful. We hope your eyes have begun to calm and return to normal. Please visit a medical practitioner if you feel it is appropriate to do so. A skin reaction is often a result of the skin reacting negatively to one or more of the ingredients contained within a product and not the level of sensitivity of the skin itself.
