Do Lash or Eyebrow Growth Serums Really Work After 50?

Somewhere around my 50s, the lashes and brows I took for granted started to thin out. Can anyone relate?! Hormones, age, even years of tweezing, it all adds up. The beauty industry swears that lash and brow serums can help, but do they really work once you’re past 50? The short answer is: yes, some can, but results vary depending on the formula and your own hair growth cycle. Here are a few of the most popular options.

As with all beauty and skincare, I suggest starting slowly. With a lash serum, wipe off the excess, and apply only a small amount. If you experience any irritation, skip a day or two and try even less the next time. It can take a few days before your lashes adapt.

Just remember, most serums take a couple of months to really show changes, so consistency is key.
