Unveiling the Secret: The Science Behind Our Serums

If you’ve seen the dramatic results our lash and brow serums deliver, you might guess their secret is some kind of miracle. It’s not. The truth about how our serums work? It’s all in the science.

How lash and brow serums work is (in some ways) similar to the science behind skincare serums. Like skincare, lash and brow care is all about choosing the right key ingredients in serums. You might be familiar with peptide-enriched serums and hydration boosting serums for your skin. These ingredients can also be helpful for your lashes and brows.

In this post, we’ll explore the science behind anti-aging serums for your lashes and brows. We’ll explain why RevitaLash® Advanced and RevitaBrow® Advanced work so well for lashes and brows. We’ll explore why they’re among the top-rated serums in their category. And we’ll break down why they’re the best serums for dry and dull lashes and brows – so let’s dive in.

What Makes Our Serums Special?

Their Ingredients Our science-backed serums for lashes and brows have set an industry gold standard, for good reason. They’re physician developed, clinically tested, and they use some of the most advanced technology you’ll find in the category.

Let’s explore the exclusive technology that powers our lash and brow serums:

BioPeptin Complex®: Found in our RevitaLash® Advanced eyelash serums and our RevitaBrow® Advanced brow serum. Our exclusive technology includes peptides, biotin, lipids, and green tea extract rich in panthenol. This combination helps condition, strengthen, and soften lashes and brows. It also protects them from breakage and brittleness.

Revitasome® Technology is now in all three of our lash serums: RevitaLash® Advanced, RevitaLash® Advanced Sensitive, and RevitaLash® Advanced Pro. This plant-based liposomal encapsulated delivery system offers time-release technology for lashes. The technology is designed to aid in absorbing ingredients into the eyelash hairs for optimal results.

The Curl Effect®: All three of our RevitaLash® Advanced serums contain this breakthrough technology. Not only does it condition and nourish lashes, but it also can give them a natural lash lift and curl. The results are eye-opening!
ReGenesis® 5D: Exclusive to our RevitaLash® Advanced Pro serum (only available through select professionals). This technology features peptides, lipids, and fortifying factors that work synergistically to nourish and improve the quality of hair. It renews lashes and defends against breakage and brittleness, for more beautiful, healthier lashes.

In addition to our exclusive technologies, our serums also feature botanical ingredients that benefit lashes and brows. These include:

Ginseng and Swertia japonica are in all our lash and brow serums. These extracts are rich in antioxidants and vitamin B. They help protect and revitalize lashes and brows.

Saw palmetto: This botanical extract is rich in fatty acids and plant sterols, aiding in conditioning and enhancing shine. You’ll find it in our RevitaLash® Advanced and RevitaLash® Advanced Pro serums.
Aloe vera: This botanical is renowned for its soothing and calming abilities. You’ll find it in our RevitaLash® Advanced Sensitive serum, which includes ingredients specifically designed to be gentle for sensitive eyes.

Calendula: Our RevitaBrow® Advanced brow serum uses this natural ingredient. It helps brow hairs retain moisture for better flexibility.

We’re proud of the high-quality ingredients we use and the care we put into developing our formulas. All our serums are oil-free, hypoallergenic, and made without parabens, phthalates, fragrance, or gluten. They’re physician developed, third-party safety tested, and reviewed by independent experts, including ophthalmologists and board-certified dermatologists.

Our lash and brow serums built their reputation on word of mouth. Today, almost 20 years since our debut, the beauty industry still can’t stop talking about how good they are.

“I've tried other brow conditioners over the years, but always come back to this one,” says an editor at Allure of our RevitaBrow® Advanced. The beauty expert publication has picked our brow serum for its Best in Beauty Awards for 12 years straight.

How to Incorporate a Lash or Brow Serum into Your Routine

Now that you’ve learned all about our powerful serums for repair and conditioning, it’s time to add them to your beauty routine.

Using a lash or brow serum only takes a few seconds a day – and the payoff is worth it. Plus, you can still use the makeup and skincare products you already love, as long as you apply your serums correctly.

To use lash and brow serums like RevitaLash® Advanced and RevitaBrow® Advanced, follow these steps:

1. Prep your eye area. Begin by removing any makeup, dirt, and oil from your lashes and brows using our Micellar Water Lash Wash.

Choosing an oil-free cleanser or makeup remover like this one is important. Why? Oil-based products can leave behind a film which may create a barrier between your lashes and brows and the serum. Remove any oily residue before applying your serums.

2. Apply your lash serum. Once a day, apply one thin line of RevitaLash® Advanced directly to clean, dry upper eyelashes only, above the lash line.

No need to apply more than a very small amount of serum. If you use too much, the serum could drip into your eye, which may cause irritation or other unwanted effects. You only need to dip the applicator brush into the bottle one time for both eyes.

3. Apply your brow serum. Once a day, apply several short strokes of RevitaBrow® Advanced to clean, dry eyebrow hair, using the specially designed eyebrow applicator.

4. Let your serums dry. Wait two to three minutes for your lash and brow serums to dry completely. Once they are dry, you can finish your beauty routine. You can add any products you like, such as eye cream, brow gel, or mascara.

Better Lashes and Brows with Physician-Developed Science

The bottom line: You don’t need magic, dumb luck, or good genes to get lashes and brows that turn heads. All you need is science.

Our lash and brow serums are global sensations for good reason. They combine advanced technology with results-driven botanicals to deliver proven results. Add them to your routine and your lashes and brows will thank you.
