Bye Bye Under Eye Bags Treatment is the top coat of your routine—apply it as the last step. We do not recommend applying any skincare or makeup products on top. It’s intended to use on top of your concealer makeup, over your eye moisturizer or by itself. Before applying the product, cleanse your face and apply your eye moisturizer. Let your skincare fully absorb. Follow with makeup (if desired) and allow it to dry down before applying Bye Bye Under Eye Bags Treatment.
