DUO Strip Eyelash Adhesive for Strip Lashes

I have been using the Duo dark-tone glue since probably about 2011? It's been so long I can't remember exactly when I started, and BOY OH BOY was I surprised when I twisted my newest tube open to find basically a whole new product was being squeezed out. There was an adjustment period but I ultimately like the new formula more than the old one. Here's the major differences: 1. The color used to be a medium gray straight out of the tube and grew darker as the glue dried and became tacky. The only time the glue became a true black with the original formula was when it was completely dry. This helped me to know when the lash was ready to be applied. Now it comes out black right off the bat, and the first time I saw it I panicked and thought I had a bad tube that had dried out in the warehouse before it shipped to me. Thus far, this is the only con I can find. 2. The new formula is much more stable and easier to apply to a lash band in a uniform fashion, it has a higher viscosity and comes out tacky. The old formula was runny and would bleed into the lashes, thereby lowering the number of times I could wear a pair of lashes. The improvement in viscosity of the new formula has also stopped the waste that would leak out and stick to the lid almost entirely, making the tube last longer and prolonging the life of your dollars spent. 3. Applying the lash has also become easier with the new formula. Although the color change is no longer an effective way to estimate the tackiness of the glue, the new formula means the lash can be applied much sooner and will hold it's grip on my lash line even if the glue is still setting up. The old formula had a small window of time where you could apply the lash and rely on it sticking down. It would either be too dry to stick or too runny to stick and would smush glue into your eye or the surrounding make-up. So far, the new formula has not leaked into my eyes or through my top lash into my bottom lash (gluing them together) in the few weeks I have been using this new tube. On average I give it 30-45 seconds before I apply the lash. My make up routine has become significantly faster in the mornings because I don't have to fight with the lash or clean up the aftermath. 4. Removal has also improved. With the old formula, the dry glue would stick to the band and not my lashes so I would have to remove them slowly and gingerly so I wouldn't remove lashes from either. This would also require additional cleaning of the false lashes-literally combing dry glue out of the hairs. With the new formula, the glue pops off the lash band and stays on my eyes so I can quickly wash it off in the shower. I have noticed that the removal of the glue in the shower has also improved and I do not find tiny chunks still embedded in my eyelashes after washing my face anymore. In my panic upon seeing the differences I did jump on Google to see what other people were saying and found a few complaints from people with sensitive skin (I guess) complain that they experienced swelling and redness from the new formula and could not use this brand anymore. That said, those comments were left on TikTok make up videos, so who even knows if those were real people and not just bots. I use the glue 5-6 days a week and have not had irritation of any sort. I do not have any allergies and do not have particularly sensitive skin so that's worth noting. All-in-all, I will continue to use the Duo dark tone glue and have enjoyed the new formula.
