In 2024, lash serums have become a popular way to grow long and fluttery eyelashes, with a market value of nearly $800 million in the U.S. Users on TikTok have been showcasing their results, but many are now experiencing unpleasant side effects. Some users have reported swollen and raw eyes, while others have developed issues such as reddish rings and sunken eyes, leading to what is known as „eyelash serum blindness.“ Even doctors have fallen victim to the allure of longer lashes, with one plastic surgeon developing an eye bulge after using lash serum containing prostaglandin.
Prostaglandin analogs are the main ingredients in lash serums, and they are known to have lash-enhancing benefits. However, these ingredients can also come with potential side effects, such as hyperpigmentation, irritation, and inflammation. Prostaglandins can also cause muscle weakness, as seen in the case of a doctor who experienced asymmetry in her eyes after using lash serum. While serious side effects are rare, some users may experience irritation or hyperpigmentation. Some lash serum brands argue that prostaglandins are not dangerous, and have conducted their own research to support their claims.
Not all lash serums contain prostaglandins, and alternatives like castor oil may be a safer option for those looking to enhance their lashes. Castor oil is known for its hair strengthening properties, although there is limited scientific evidence to support its effectiveness in stimulating hair growth. Ultimately, there are safer alternatives to lash serums, such as lengthening mascara, which can provide similar results without the risk of damaging side effects. It is important for users to be aware of the potential risks associated with lash serums and to explore safer options for achieving longer lashes.
