I have tried many hair growth serums before for my lashes and brows, and there was always something wrong with them. In the past, the ones I've used had negative side effects, like changing the color of your eyes, or if it's made with minoxidil, it can reduce collagen production in the skin, or it simply does not work at all. This is the first eyelash growth serum I've tried where they stand out from the mainstream market by using hydrating products with botanical ingredients and peptides. I have used this product every day for about a month now, and I can tell it's amazing in many ways. Let me explain. The formula is gentle. I've been using this in my water line, and even if the product gets into my eyes, there is no burning sensation; it just feels like eye drops. I've been using this 1x a day for 2 weeks and was honestly surprised when I started to see regrowth. I have a condition called Trichotillomania, where I impulsively pluck my hair when stressed, which has caused me to lose most of my eyebrow hairs with no room for regrowth without intervention, so I have my eyebrows microbladed. I've also plucked my eyelashes to a point where they grew back sparse and straight, losing their natural curve. After using this product daily for 2 weeks, I started seeing regrowth in both my eyebrows and a patch in my lash line that was bare. This motivated me to start using the serum 2x a day, morning and night, for the last 2 weeks. In total, I've used this product for about 4 weeks, and I regrew about 70% of my eyebrows, and my lashes have grown longer, resulting in that natural curve returning. There is still room for progress. Now that I am seeing this regrowth, I am noticing that the density of my brows and lashes is also improving. I'm honestly so happy and surprised because I bought this expensive serum on a whim, not expecting it to actually do much, but with this issue of mine, I'm always on the lookout for a solution. The ingredient list is cleaner and more natural than anything I've used, more hydrating, and provides faster results, so I've decided to repurchase another tube. It claims that one tube lasts 6 months, but since I am using it on my eyebrows as well, I expect it to last maybe 2-3 months. Overall, I'm very happy, and I'd recommend trying it out!
