Megan Markle’s favorite eyelash serum! This original, one-of-a-kind, Ophthalmologist developed eyelash conditioner enhances the look of lashes and protects against breakage, while improving health, flexibility and strength, for lashes that thrive, naturally. Patients have asked what the difference is between RevitaLash and Latisse (another eyelash serum). Both work and produce noticeable results. However, RevitaLash is not as strong as Latisse. Many people cannot use Latisse without irritation. We have found that RevitaLash does not cause this issue. The RevitaLash rep said it like this; Latisse is stronger and produces more dramatic results, she compared it to a habanero pepper whereas RevitaLash is more like a jalapeno pepper. Not as strong but still produces results.
