Hi Lauri, I am SO sorry to hear you didn't love the serum! Most people can use the lash treatments once per day every day without an issue however, some people do need to start off using the product slowly. Instead of using it every day, allow your eyes to completely re-adjust before applying it again. This means it might be 4-7 days in between applications which is fine! This allows your eyes to get used to the serum without a reaction. Keep in mind, when applying the product less is more. Don't re-dip the wand, 1 dip is enough for both eyes and apply to the upper lash line only. We offer a 90 Day Satisfaction Guarantee and want you to have an exemplary Babe Lash experience. We recommend taking full advantage of our 90-day Satisfaction Guarantee to allow enough time for your body to acclimate to this new product. If you have any additional feedback or questions please do not hesitate to reach out to us directly at info@babelash.com
