Quick Recipe

Prep time: 15 minutes (plus overnight infusion)

Best for: Boosting lash appearance, strength, and shine

Use type: Oil serum

Main ingredients:

  • Flaxseed
  • Dried Rosemary
  • Castor Oil

Ingredients

  • 1 tablespoon whole flaxseeds
  • 1 teaspoon dried rosemary leaves
  • 2 tablespoons castor oil (cold-pressed, hexane-free preferred)
  • 1 vitamin E capsule (optional, for preserving)
  • 1/4 cup distilled water
  • Small, clean mascara wand or spoolie
  • Small, airtight container or dropper bottle

How to Make It

  1. Prepare Flaxseed Gel: In a small saucepan, combine flaxseeds and distilled water. Bring to a gentle boil, then reduce heat and simmer for 5-7 minutes, stirring occasionally, until a gel-like consistency forms.
  2. Flaxseeds simmering in water in a small saucepan forming a gel-like consistency
    Simmer flaxseeds to create a nourishing gel base for your serum.
  3. Strain the Gel: Remove from heat and immediately strain the mixture through a fine-mesh sieve or cheesecloth into a clean bowl. Press firmly to extract all the gel. Discard the flaxseeds. Let the gel cool completely.
  4. Infuse Rosemary: In a separate small, heat-safe jar or bowl, combine the castor oil and dried rosemary leaves. You can gently warm this mixture in a double boiler for 15-20 minutes to aid infusion, or simply let it infuse at room temperature for at least 24 hours, or up to a week, shaking occasionally.
  5. Strain Rosemary Oil: Strain the rosemary-infused castor oil through a fine-mesh sieve or cheesecloth to remove the rosemary leaves.
  6. Combine & Store: Once the flaxseed gel is cool, mix approximately 1-2 teaspoons of the rosemary-infused castor oil with 1 tablespoon of the flaxseed gel. If using, puncture a vitamin E capsule and squeeze the oil into the mixture. Mix well.
  7. Transfer: Pour the finished serum into a clean, airtight container or a small dropper bottle. If using a dropper bottle, ensure the consistency is not too thick. Adjust the amount of flaxseed gel if needed.

How to Use It

  1. Clean Lashes: Ensure your lashes are clean and free of any makeup.
  2. Apply Gently: Dip a clean mascara wand or spoolie into the serum. Carefully apply a thin layer to your upper and lower lash lines, ensuring you cover the base of the lashes. Avoid getting the serum directly into your eyes.

Why These Ingredients Are Used

Flaxseed

Flaxseeds are known for their rich content of omega-3 fatty acids and lignans, which can help nourish hair follicles. When prepared as a gel, flaxseed provides a smooth, conditioning base that may help support the strength and shine of your lashes.

Rosemary Oil

Rosemary is a traditional herb often used to promote hair health. When infused into an oil, rosemary may help stimulate the hair follicles, supporting the appearance of denser, stronger-looking lashes. It’s often included in natural remedies for its revitalizing properties.

Castor Oil

Castor oil is a popular choice in beauty for its rich fatty acid profile, particularly ricinoleic acid. It’s believed to deeply moisturize and condition the lashes, potentially helping to reduce breakage and supporting a thicker, fuller appearance over time.

What Results to Expect

With consistent use, you may notice your lashes appear more conditioned, feel stronger, and look shinier. This natural serum can help support the appearance of fuller and healthier lashes. Individual results can vary, and patience is key with natural remedies.

Safety Notes

  • Patch Test First: Before applying to your lashes, perform a patch test on a small, inconspicuous area of skin (like behind your ear or inner arm) to check for any allergic reactions or irritation. Wait 24 hours.
  • Avoid Eye Contact: Be extremely careful to prevent the serum from entering your eyes. If it does, rinse thoroughly with cool water.
  • Discontinue if Irritated: If you experience any redness, itching, burning, or discomfort, discontinue use immediately.
  • Use Clean Applicators: Always use a clean mascara wand or spoolie to prevent bacterial contamination, which can lead to eye infections.
  • Storage: Store the serum in a cool, dark place. Due to the flaxseed gel, this serum is best used within 1-2 weeks. For longer storage, consider making smaller batches more frequently.
  • Consult a Professional: If you have sensitive eyes, a history of eye conditions, or are pregnant or breastfeeding, consult with a doctor or ophthalmologist before using any DIY eye remedies.
