Buying Guide: Key Purchase Considerations

  • Ingredients and sensitivities: Look for prostaglandin-free formulas if you have sensitive eyes. Plant-based and organic ingredients favor those seeking natural options.
  • Target and routine: Decide whether you want a dedicated lash serum, a brow-focused product, or a dual-use oil. Consider whether you prefer a wand, brush, or applicator that minimizes mess.
  • Application and ease of use: Dual-ended wand designs can simplify precise application to the lash line and brows, reducing spill and waste.
  • Product form and shelf life: Pure castor oil blends have long shelf lives, but some serums with multiple botanicals may vary in color and scent due to natural ingredients.
  • Brand transparency and testing: Vegan, cruelty-free, and USA-made claims may influence purchasing decisions based on your values.
  • Results timeline: Expect differences in response times; some formulations show noticeable fullness within 4 weeks, while others may take longer with consistent use.
  • Value and size: Compare bottle size and price per milliliter to gauge long-term value, especially for daily use over several months.
