With so many eyelash serums available, choosing one can feel overwhelming. Some highlight peptides, others vitamins, botanical extracts or moisturising ingredients.
So, what should you actually look for in a lash serum?
The answer isn't simply “the more ingredients, the better.” A well-formulated lash serum should contain ingredients that help condition and support the appearance of natural lashes, along with clear instructions and appropriate product claims.
What Ingredients Should You Look For in a Lash Serum?
When comparing lash serums, look at the complete formula rather than focusing on a single ingredient.
Peptides
Peptides are short chains of amino acids commonly used in cosmetic formulations. In lash serums, they may be included as part of a conditioning formula to support the appearance of healthier-looking lashes.
However, not all peptides are the same, and having more peptides doesn't automatically make a serum better.

ProVitamin B5
Also known as panthenol, ProVitamin B5 is commonly used in hair and cosmetic products for its conditioning properties. In a lash serum, it can help condition the lashes and support their healthy-looking appearance.
Vitamins
Some lash serums contain vitamins such as Vitamin C and Vitamin E as part of their formulation. Their role depends on the overall formula, so it's useful to consider the complete ingredient list rather than one ingredient alone.
Hyaluronic Acid
Hyaluronic acid and its derivatives are commonly used for their moisturising and conditioning properties. Ingredients such as Sodium Hyaluronate can help support the conditioned appearance of lashes.
Botanical Extracts
Botanical ingredients such as aloe vera may also be included for their conditioning or moisturising properties.
As with other ingredients, their presence alone doesn't determine whether a lash serum is better.
Does a Lash Serum Need Peptides?
Not necessarily.
Peptides are one type of ingredient used in lash-conditioning formulas, but they aren't the only factor to consider.
When choosing a lash serum, look at:
- The complete ingredient list
- The purpose of the ingredients
- Application instructions
- Evidence supporting the product's claims
- Whether the formula fits your routine
The formulation as a whole matters.
What Else Should You Consider?
Ingredients are only part of the decision.
Clear Application Instructions
Choose a product with clear instructions on how and how often to apply it. ILASH, for example, is designed for once-daily application along the upper lash line.
Ingredient Transparency
Look for brands that make their complete ingredient information easy to find, particularly when applying a product around the delicate eye area.
