There’s a high price-tag. It’s a whopping $150 per tube, and it is unclear how long the tube will last with the recommended daily use. The instructions are unclear. It’s unknown what will happen if the product does not apply or rest on the lashes evenly. Will it only work on some of the lashes? The longevity has not been fully tested. Lash Boost has only been on the market for around six months, so the long-term results and side-effects are not widely known. The ingredients may produce unwanted side-effects. Lash Boost contains the ingredient isopropyl cloprostenate, a synthetic prostaglandin analog. The FDA noted that the use of the products which contain this ingredient should be supervised by a licensed practitioner, as isopropyl cloprostenate may lower intraocular pressure and other side effects such as ocular irritation, hyperemia, iris color change, macular edema, ocular inflammation and interference with glaucoma therapy.
