Latisse vs SpectralLASH

What Is Better Spectral.Lash or Latisse?

Do you want long, full and luscious eyelashes? For the majority of women, this is a huge pain-point. It’s why more and more salons are offering eyelash extensions for upwards of $150 a pop, plus the cost of maintenance.

That’s a chunk of change on its own, but extension refills can set you back another $40 to $50 every few weeks. 

Not to mention, eyelash extensions can harm your natural lashes, leaving you with sparse, wimpy fringe once you take off the fakes.

Are you doomed to deal with short lashes forever? Nope! Let’s break down the two best eyelash growth serums, along with the good, bad and the ugly when it comes to growing your natural eyelashes.

What is Eyelash Hypotrichosis?

Eyelash hypotrichosis is the medical name for having inadequate or not enough lashes. Eyelash hypotrichosis is defined as having lower than average length, thickness and/or number of eyelashe

Do Eyelash Growth Serums Work?

Yes and no.

Unfortunately, most eyelash growth serums sold in stores don’t work because the active ingredient is biotin. Biotin is a B complex vitamin that most of us get naturally through foods like whole grains, nuts and egg yolks. It’s gained a cult following in recent years, thanks to claims that it helps grow hair, eyelashes and nails — and makes skin glow.

Unfortunately, biotin alone won’t transform your lashes.

However, premium eyelash growth serums, like DS Laboratories Spectral.Lash are formulated with active ingredients soy protein, panthenol, and peptides that have proven to show eyelash growth quick, in a matter of a couple weeks.

DS Laboratories Spectral.Lash – Eyelash Stimulator

How To Use Spectral.Lash

  • Start by ensuring that the face is clean and makeup is removed.
  • Click the button to dispense the solution. Draw the applicator carefully across the skin of the upper eyelid as if applying eyeliner. Repeat for the lower eyelid. If solution gets into the eye, it is not expected to cause harm.
  • The eye should not be rinsed.
  • For best results, apply Spectral.LASH twice daily, morning and evening.
  • After several weeks of use, you can switch to once-daily application and maintain the results already achieved.

Precautions – For optimal hygiene and to limit any chance of eye infection, do not share your Spectral.LASH pen with others. Take great care when applying to avoid eye injury. Proper application requires that you bring the tip close to the eye, and the product needs to be applied with a steady hand. Do not use this product if you cannot apply it safely.

LATISSE® (bimatoprost ophthalmic solution) 0.03%

Latisse is the only FDA-approved lash growth treatment. Note, due to the fact that a doctor needs to prescribe it to you, the formula is derived from a drug used to treat glaucoma, which has been found to enhance both the length and thickness of lashes. “Latisse works by interfering with the eyelash growth cycle using prostaglandin analogs,” explains Great Neck N.Y.-based dermatologist Dr. Jeannette Graf. “This prolongs the eyelash growth cycle resulting in longer and thicker lashes.”

LATISSE Side-effects

  • Do not use LATISSE® if you are allergic to one of its ingredients. If you use/used prescription products for eye pressure problems, use LATISSE® under doctor care.
  • May cause brown darkening of the colored part of the eye which is likely permanent.
  • LATISSE® may cause eyelid skin darkening which may be reversible. Only apply at base of upper lashes.
  • DO NOT APPLY to lower lid.
  • Hair may grow outside the treatment area.
  • If you have eye problems/surgery, consult your doctor. Common side effects include itchy and red eyes.
  • If discontinued, lashes gradually return to previous appearance.
  • These are not all the possible side effects of LATISSE.
  • Editor’s Note: As per Latisse’s website – for more information, please talk to your doctor.

Can I buy Latisse over the counter?

No, Latisse is not available over-the-counter (OTC) as it is a prescription medication in the United States. You cannot simply buy Latisse online as the first step is getting a Latisse ® prescription from a medical provider before a pharmacy will dispense it.

  • Made by the makers of Botox, Allergan
  • Clinically proven


  • Need a perscription
  • High-risk side effects
  • Might change eye color
  • Can ONLY use on upper lashes
  • 5mm at CVS is $222
  • Eyelashes thin when usage stops
  • 5-6 months to see results

Why Can’t LATISSE Be Used On Lower Lashes?

Latisse is only designed for use on your upper eyelids to improve the length, thickness and color of your upper eyelashes. Do not apply Latisse to the lower eyelid. Doing so increases the risk of the Latisse solution coming into contact with the eye and causing side effects.

Can Latisse Be Used As A Substitute For Mascara?

LATISSE® does not work in place of mascara, but rather is a treatment to grow lashes for those with inadequate or not enough lashes and requires a prescription from a doctor. Many of LATISSE® patients still use mascara.

Prescription vs. Over the Counter Eye Serums

Currently, Latisse is the only FDA-approved lash growth treatment. In addition to the fact that a doctor needs to prescribe it to you, the formula is derived from a drug used to treat glaucoma, which has been found to enhance both the length and thickness of lashes. “Latisse works by interfering with the eyelash growth cycle using prostaglandin analogues,” explains Great Neck N.Y.-based dermatologist Dr. Jeannette Graf. “This prolongs the eyelash growth cycle resulting in longer and thicker lashes.

On the other hand, OTC serums tend to be more of a conditioning, repairing treatment for lashes. Usually these formulas are enriched with antioxidants and peptides like apple stem extract, biotin, and castor oil, to name a few. While these serums can help lashes appear fuller, it’s important to note that they won’t increase actual lash growth. “The length of lash appearance is different to each individual, but it is important to recognize that only prescriptions like Latisse will actually increase lash growth that will reverse once you stop applying the product,” says NYC-based Cosmetic Dermatologist, Dr. Paul Jarrod Frank.

“Patients who have tried both may claim to have better results with one than the other,” says Dr. Hanson. “Ultimately, it comes down to personal preference.” Some people feel more comfortable purchasing Revitalash because it has less chance of producing side effects, while some prefer to start with a more potent product.
