How to Swap to Non-Toxic lash serums:

Here's how to swap to non-toxic lash serums:

What to know about lash serum

Lash serums are applied daily to one of the most sensitive areas of your body — right along the lash line, near your eyes. Because of this high proximity and frequent use, the ingredients in your serum matter more than in many other products.

  • Some lash serums rely on synthetic fragrances, harsh preservatives, or hormone-disrupting ingredients like parabens and phthalates to extend shelf life or add scent.
  • Welpr looks for clean formulations with purposeful ingredients, safe preservatives, and no unnecessary additives — especially important for a product used so close to your eyes every day.

Review the lash serum you already use

Check whether your current lash serum meets Welpr's standards by scanning its ingredient label. Open the Welpr Personal Care and Cosmetic Scanner, take a photo of the ingredient list, and it will flag any concerning ingredients.

  • Look out for "fragrance" or "parfum" on the label — these often indicate undisclosed synthetic ingredients.
  • Since lash serum is used daily near the eyes, prioritize checking it before products you use less often or further from sensitive areas.

Use your current lash serum more carefully

If you're not ready to switch yet, small adjustments in how you apply your serum can reduce unnecessary exposure. A little care with application goes a long way near the eye area.

  • Apply only to the lash line as directed — avoid getting serum directly on your eyelid or in your eye, and use the smallest amount needed.
  • If you notice any redness, irritation, or swelling, take a break from the product and consider replacing it sooner.

Choose a cleaner lash serum

Look for lash serums with simple, functional ingredient lists. The best options skip synthetic fragrance, harsh preservatives, and unnecessary additives while still being effective.

  • Choose serums that are fragrance-free or scented only with natural plant extracts, and look for certifications like EWG VERIFIED™ for extra confidence.
