Patience required [SEP] I’ve been trying out a couple of different lash serums over the past month. With my husband also using it (on his brows), while I use it on my lashes, we’ve been able to try different brands to see if there are any differences in results. This serum, by Kimuse, is very similar to the others in consistency (a thin liquid) and in how it’s applied (with a very thin brush). I have had no negative reactions to the serum, and no irritation to my eyes even when I’ve slipped and gotten some in my eye. This serum boasts results in as little as 3-4 weeks, while most others are more conservative at 6 weeks. In the few weeks we’ve been using the serums, neither of us have noticed any dramatic changes as far as lash or brow growth, but I do think I’m losing fewer lashes which is a definite plus. Honestly, I’m not sure if any serum is going to provide dramatic results, but we’ll continue for at least a few more weeks and see what happens while hoping for the best.Hopefully, I’ll be back with exciting news!<br /><br />Update: After using this, as well as other, lash growth serums for several months, I have noticed a definite improvement in the length of my lashes. I have not noticed as significant an improvement in the thickness, or volume, of my lashes, however. I believe that these types of serums do help promote growth, and I haven't been able to detect much difference between brands except that a couple of them irritated my eyes. Therefore, my conclusion is that this is helpful and the real determination of what works best will be what's most comfortable for you to use, so read the ingredients and watch for any possible allergy triggers or irritants.
