THE TRUTH ABOUT LASH GROWTH SERUMS:
WHAT TO WATCH FOR
Shigeru Lash and Brow Serum has NO Prostaglandin!
Lash growth serums can be an amazing way to enhance your natural lashes, but it’s important to be informed about potential sensitivities. Some formulas contain active ingredients that may cause irritation, discoloration, or unexpected side effects for certain users. The good news? By choosing high-quality products, such as Shigeru Beauty, following usage guidelines, and doing a patch test beforehand, you can enjoy longer, fuller lashes while keeping your eyes healthy and happy!
What you need to know about ⚠ Prostaglandin Analogs ⚠ found in many other serums.
Long, full lashes are a beauty dream, and many lash serums promise to make them a reality. However, some serums contain prostaglandin analogs—ingredients that can come with unexpected and even permanent side effects. Before applying that serum, here’s what you should know.
- ⚠ Irritated Eyes – Redness, itching, and discomfort are common reactions.
- ⚠ Eye Color Changes – In some cases, blue or green eyes may develop permanent brown spots.
- ⚠ Darkened Eyelids – The skin around your eyes can become darker over time, sometimes permanently.
- ⚠ Sunken Eyes – Some users notice a hollowed-out appearance around their eyes due to fat loss in the area.
- ⚠ Unwanted Hair Growth – If the serum spreads to other areas of your face, you may see unexpected hair growth.
- ⚠ Dry Eyes and Vision Changes – Long-term use may lead to dry eye syndrome, increased sensitivity to light, or even subtle vision changes.
What’s in Your Lash Serum?
Some larger lash serums use powerful ingredients originally designed for medical eye treatments. These ingredients extend the lash growth cycle, making lashes appear longer and fuller. But with great results can come unwanted risks.
