Achieving the look of longer, healthier eyelashes and well-defined eyebrows is a common goal for many beauty enthusiasts. When navigating the world of eye-area enhancement, understanding how to use The Ordinary lash serum—officially known as the Multi-Peptide Lash and Brow Serum—is essential for maximizing your results.
This lightweight, water-based formula is designed to support the appearance of density and health in your hair follicles without relying on harsh chemicals. By following a consistent application routine, you can leverage the power of advanced peptides to nourish your lashes and brows, helping them appear thicker and more resilient over time.
Understanding the Multi-Peptide Formula

The efficacy of this product lies in its sophisticated ingredient profile. Unlike many conventional lash enhancement solutions that rely on prostaglandin analogs—which can sometimes cause unwanted side effects like eye color changes or skin irritation—The Ordinary utilizes a thoughtful combination of technologies to support hair health. At the heart of the formula is a multi-peptide lash complex that works to condition and protect the delicate hair fibers of your lashes brows.
Key ingredients include myristoyl pentapeptide- and biotinoyl tripeptide-, which are known for their role in promoting the appearance of hair density. Furthermore, the inclusion of Larix Europaea wood extract and Camellia Sinensis leaf extract provides a botanical boost that supports the overall condition of the follicles.
This complex is designed to be gentle on the sensitive skin around the eyes while delivering targeted hydration. Because it is free of oils, silicones, and alcohol, it is suitable for most users who want to enhance the look of their natural hair without adding heavy residues that could interfere with makeup application later in the day.
Preparing Your Eyes for Application
Before you begin the process of applying the serum, your face must be properly prepped. The effectiveness of any topical treatment depends heavily on the cleanliness of the area.
If you attempt to apply the serum over residual makeup, dirt, or natural oils, the active ingredients may struggle to reach the hair follicles effectively. Therefore, the first step is to remove all traces of mascara, eyeliner, and brow products using a gentle cleanser.
Once your face is clean, pat the area around your eyes dry with a soft towel. It is important to ensure that the skin is completely dry, as residual moisture can dilute the product or cause it to run into the eyes. Some users find that applying the serum immediately after their nightly skincare routine is the most convenient method.
However, if you use heavy eye creams or oils, you should wait a few minutes for those products to absorb fully into the skin before reaching for your brow serum. This ensures that the serum remains concentrated at the base of the lashes where it is needed most.
Step-by-Step Guide to Proper Application
Learning how to use The Ordinary lash serum involves a simple, two-step process that can be integrated into your morning or evening routine. Because the formula is thin and non-greasy, it absorbs quickly, leaving no sticky or crunchy feeling behind. Follow these steps to ensure optimal delivery of the peptides to your hair:
- Cleanse your face thoroughly and ensure the eye area is completely dry.
- Dip the applicator brush into the bottle once, ensuring it is sufficiently coated but not dripping.
- Using the precision tip, draw a thin line along your upper lash line, moving from the inner corner toward the outer corner.
- Repeat the process on the lower lash line if desired, being careful to avoid direct contact with the eyeball.
- Apply the remaining product on the brush to your eyebrows, focusing on areas where you desire a fuller, thicker look.
- Allow the serum to dry for a minute or two before applying other skincare products or makeup.
Consistency is the most critical factor when using this treatment. Because hair growth cycles are naturally slow, you cannot expect overnight miracles. Most users start to see subtle changes in the appearance of their lashes and brows after several weeks of consistent daily use.
Managing Expectations and Timeline for Results
When you decide to incorporate this treatment into your regimen, it is vital to maintain realistic expectations. You might think that a few days of application will yield dramatic, long-term changes, but the biology of hair growth dictates a longer timeline.
Hair follicles undergo distinct phases: anagen (growth), catagen (transition), and telogen (resting). The peptides in the serum work to support the hair during these cycles, helping the lashes and brows look fuller and healthier as they emerge.
Generally, you should anticipate needing to use the product consistently for at least four to eight weeks before noticing significant visual improvements. During this time, the results may manifest as reduced breakage, improved texture, and the appearance of increased density. By the twelve-week mark, many individuals report that their lashes look noticeably thicker and more voluminous.
If you stop using the product, your lashes will eventually return to their natural state as the hair cycles continue. Think of this as a maintenance routine rather than a one-time fix; keeping up with the application ensures your lashes continue to benefit from the nourishing ingredients.

Common Mistakes to Avoid
Even with a user-friendly product, there are common pitfalls that can hinder your progress or cause unnecessary irritation. One of the most frequent mistakes is over-applying the serum.
Because the formula is potent, you only need a thin layer at the base of the lashes. Applying too much product does not accelerate the growth process; instead, it increases the likelihood of the serum running into your eyes, which may cause temporary blurring or mild discomfort.
Another error is inconsistent usage. Skipping days frequently interrupts the delivery of the active ingredients, which can make it difficult to maintain the progress you have made. If you find it hard to remember, try keeping the bottle next to your toothbrush so it becomes a part of your daily ritual.
Finally, avoid double-dipping the applicator into the tube multiple times during a single application session. This introduces bacteria into the bottle, which can compromise the preservative system of the serum. One dip is usually sufficient to cover both eyes and your brows.
Comparison of Application Frequency and Expectations
The following table outlines how different application habits can influence your experience with the serum.
| Frequency | Expected Outcome | Best For |
|---|---|---|
| Once Daily (Night) | Steady, consistent improvement | Most users, especially those with sensitive skin |
| Twice Daily (AM/PM) | Faster visual saturation | Users wanting to speed up the conditioning process |
| Irregular/Occasional | Minimal or no visible results | Those who are not committed to a long-term routine |
As indicated, while using the product twice a day is possible, most dermatologists suggest that once-daily application is sufficient to achieve the desired look without over-saturating the delicate skin of the eyelids.
Frequently Asked Questions
Is it better to use the lash serum in the morning or at night?
Most users prefer applying the serum at night as part of their evening skincare routine. This allows the ingredients to absorb fully while you sleep without being disturbed by makeup or environmental factors. However, you can safely use it in the morning if you prefer, provided it dries completely before makeup application.
Will The Ordinary lash serum change my eye color?
No, this serum does not contain prostaglandin analogs, which are the ingredients typically associated with the risk of iris pigmentation changes. The formula relies on peptides and botanical extracts, making it a safer alternative for those concerned about potential side effects like permanent darkening of the eye color.
How long does it take to see results?
While individual experiences vary based on your natural hair growth cycle, most people begin to see a visible improvement in the appearance of their lashes and brows after four to eight weeks of consistent daily use. Patience and regular application are the keys to achieving the best possible outcome.
Can I use this on my lower lashes?
Yes, you can apply the serum to your lower lashes if you desire. Be sure to use a very small amount to prevent the product from migrating into your eyes. If you experience any stinging or redness, stop the application to the lower lash line immediately and consult a professional.
In conclusion, mastering how to use The Ordinary lash serum is a straightforward endeavor that rewards consistency and patience. By integrating this peptide-rich formula into your daily beauty ritual, you provide your lashes and brows with the nourishment they need to look their best.
Remember to keep the application area clean, use only the recommended amount, and give your hair the time it needs to cycle through its natural growth phases. With a steady hand and a committed schedule, you can look forward to a fuller, more defined appearance for your lashes and brows.
