1. What is The Ordinary Lash Serum?

Understanding The Ordinary’s Multi-Peptide Formula
The Ordinary Multi-Peptide Lash and Brow Serum is a lightweight, water-based treatment designed for twice-daily application along the lash line and eyebrows. Unlike prescription serums like Latisse (which contains prostaglandins), this formula relies on 11 key ingredients, including four proprietary peptide complexes :

• SYMPEPTIDE XLASH®: Features Myristoyl Pentapeptide-17 to boost lash density.
• Widelash™: Combines Biotinoyl Tripeptide-1 and Panthenol to strengthen hair anchorage.
• REDENSYL™: Uses plant extracts (like Larch Tree) to stimulate follicles.
• CAPIXYL™: Includes Acetyl Tetrapeptide-3 to prevent hair loss.

The serum is fragrance-free, vegan, and cruelty-free, making it suitable for sensitive eyes and contact lens wearers . A 5ml bottle typically lasts 3–6 months with daily use .

2. How Peptide Technology Promotes Lash Growth

The Science Behind The Ordinary Lash Serum
Peptides vs. Prostaglandins: A Safer Approach
Most lash serums fall into two categories: peptide-based or prostaglandin-based. Prostaglandin analogs (like bimatoprost in Latisse) can cause iris darkening, eyelid pigmentation, and orbital fat loss . The Ordinary avoids these risks by using peptides—short chains of amino acids that communicate with hair follicles to:

• Extend the growth phase of the lash cycle (anagen phase)
• Reduce shedding by strengthening the hair root
• Increase density by activating dormant follicles

Table: Key Ingredients and Their Functions

Ingredient Complex	Key Components	Primary Benefit
SYMPEPTIDE XLASH®	Myristoyl Pentapeptide-17	Enhances lash density
Widelash™	Biotinoyl Tripeptide-1 + Panthenol	Strengthens hair roots
REDENSYL™	Larch Tree Extract + Green Tea	Stimulates follicles
CAPIXYL™	Acetyl Tetrapeptide-3 + Clover Flower	Prevents hair loss

According to dermatologist Dr. Marisa Garshick, peptides offer a « lower-risk alternative » for those seeking subtle improvements without medical side effects .

3. Real User Results: Before and After Evidence

Does The Ordinary Lash Serum Actually Work?
Clinical Studies vs. Real-World Outcomes
An independent 12-week study of 30 users reported « significant improvement in volume, fullness, and density » in 4 weeks . But real-world data paints a nuanced picture:

Positive Experiences

• 65% of Amazon reviewers noted longer, thicker lashes, with baby hairs appearing in 7–10 days .
• Refinery29 testers saw « bushier, thicker lashes » after 8 weeks, especially when using mascara .
• Blogger Nikki P. documented fuller outer lashes and reduced fallout after 4 months .

Limitations and Criticisms

• Inconsistent results: 30% of Cult Beauty users saw « no change after 3 weeks » .
• Slower than prostaglandin serums: In a head-to-head test, UKlash (a prostaglandin serum) outperformed The Ordinary in length after 8 weeks .
• Brow results weaker: Many users reported better lash outcomes than brow growth .

4. How to Use It for Maximum Results

Optimizing Your Lash Serum Routine
Step-by-Step Application Guide

1. Cleanse: Remove makeup/oils with a gentle cleanser.
2. Dry: Pat skin thoroughly (serum won’t stick to damp skin).
3. Apply: Swipe a thin layer along the upper lash line (like liquid liner). Avoid the waterline to prevent irritation .
4. Consistency: Use morning and evening for 8–12 weeks.

Critical Tips:

• Patch test first on your forearm to check for redness/itching .
• Store horizontally: The thin formula pools at the tube’s bottom near the end .
• Avoid common mistakes: Don’t apply to wet lashes, oversaturate the brush, or expect results in <4 weeks .

5. Safety Profile: Side Effects and Risks

Is The Ordinary Lash Serum Safe?

• 5–10% of users report mild redness, itching, or swelling (especially if applied too close to the eyes) .
• No pregnancy safety data: The Ordinary advises consulting a doctor before use .
• Lash extension compatibility: Not formally tested; consult your technician .

Compared to Latisse (which requires a prescription), this serum is significantly lower-risk but may work slower .

Frequently Asked Questions

Your The Ordinary Lash Serum Questions, Answered

How long does a bottle last?

A 5ml bottle lasts 3–6 months with nightly use. Apply sparingly—just one thin swipe per lash line is enough. Over-application wastes product and increases irritation risk.

Can I use it with lash extensions?

Proceed cautiously. While the serum won’t dissolve adhesive, residue buildup can weaken extensions. Apply only to the skin (not lashes) 24 hours after fills. Many technicians recommend peptide-free alternatives like Nanolash for extension-safe growth.

Why aren’t my lashes growing?

Common reasons include:

1. Inconsistent use: Skipping >2 days/week resets progress.
2. Genetic factors: 15–20% of users see minimal results due to follicle sensitivity.
3. Health triggers: Thyroid issues or vitamin deficiencies (like biotin) can stunt growth.
   Solution: Pair with biotin supplements and track progress with monthly photos.

Is it safe during pregnancy?

No clinical data exists. Peptides are likely low-risk, but hormonal changes alter lash growth cycles. Dermatologists like Dr. Dhaval Bhanusali advise waiting until postpartum unless prescribed.

Can I apply mascara afterward?

Yes! Wait 5 minutes for absorption, then apply mascara. Avoid waterproof formulas—they require harsh removers that strip peptides.
