Key Differences Between the Serums
When it comes to lash serums, NourishLash and Rodan + Fields Lash Boost have both made waves in the beauty industry. Each of these serums promises thicker, longer lashes, but how do they measure up against each other?
- Key Active Ingredients

NourishLash – Peptide complex NourishLash harnesses the power of a proprietary peptide blend. But what exactly are peptides? In essence, peptides are short chains of amino acids.
Think of them as tiny protein fragments. When it comes to lashes, these peptides can support and nourish hair follicles. The end goal? To promote healthier and more robust lash growth.
Now, let’s compare this to Rodan + Fields.
Rodan + Fields – Isopropyl Cloprostenate Rodan + Fields relies on a completely different active ingredient. Isopropyl Cloprostenate is an FDA-approved prostaglandin analog.
Prostaglandins are naturally found in our bodies and have various roles, including involvement in hair growth. This particular ingredient, when applied to lashes, aims to extend the growth phase of the hair cycle.
- Clinical Trial Results
Results matter. So, how do these serums stack up in clinical trials?
NourishLash – 131% increase in length A remarkable 131% increase in lash length is no joke. This means that in clinical settings, individuals using NourishLash witnessed their lashes grow more than double in length. It’s a testament to how effective peptides can be when formulated correctly.
On the flip side, we have:
Rodan + Fields – Up to 55% increase in length While 55% might seem like a smaller number compared to NourishLash, it’s still a significant boost. Imagine your lashes growing over half their original length! This result showcases the potential of Isopropyl Cloprostenate as a lash-enhancing ingredient.

- Potential Side Effects
With beauty products, there’s always a balance between benefits and potential side effects.
NourishLash – Very minimal side effects The beauty of using peptides? They’re generally considered safe. NourishLash users can enjoy their newfound lash length without much concern about adverse reactions.
However:
Rodan + Fields – May gradually darken eyelids Every product has its quirks. For Rodan + Fields, there’s a small chance of eyelid darkening. This is linked to its main ingredient, Isopropyl Cloprostenate. It’s worth noting that while this effect is rare, it’s a possible side effect of prostaglandin formulas.
- Application Method
Using a product correctly ensures you get the best results.
NourishLash – Apply nightly to clean lash lines Nighttime application can be convenient. You can make it part of your nighttime skincare routine. By applying NourishLash before bedtime, you give those peptides a full night to work their magic.
In contrast:
Rodan + Fields – Apply once daily to upper lash lines Morning routines can be bustling, but for some, applying Rodan + Fields can be a refreshing start. There’s also a strategic reason behind this timing. By applying in the morning, users might reduce the risk of potential eyelid darkening.

Rodan + Fields – Around $150 per tube While Rodan + Fields does come with a steeper price tag, beauty enthusiasts might be willing to invest. Especially if they’re after the specific benefits offered by the prostaglandin formula.
In the world of lash serums, both NourishLash and Rodan + Fields have carved their niches. While they operate on different ingredients and price points, they both offer the promise of longer, more luxurious lashes. The choice, ultimately, boils down to individual preferences and needs.
