Lashes to Die For Turbo Nighttime Eyelash Treatment has a name that conjures images of fast results; apply tonight, and wake up to long, dark lashes ready for extra enhancement by mascara. Unfortunately, unlike previous versions of Lashes to Die For, this one doesn't contain anything with scientific research proving it will change the growth rate or cycle of eyelashes. Simply put, assuming the ingredient list the company provides is accurate, using this product won't lead to longer, thicker, or darker lashes.

The potential "active" ingredient in this product is a synthetic peptide known as myristoyl Pentapeptide-17. The Jan Marini brand was the first to use this peptide in a lash growth product and, not surprisingly, they filed a patent application for this. Although a patented ingredient sounds impressive, patents don't have to prove a product works as claims—only that the group or person applying for the patent has found a unique application for something. Remember, patents don't guarantee effectiveness.

We have looked (and looked) and, so far, there isn't any published, peer-reviewed research proving this peptide is the one to use for enhancing lash growth. Apparently it has some effect, but you're left to take the word of the companies selling the product or the company selling the peptide to other brands. As most of us know, that can be a gamble that leads to disappointment and wasted money. And for what Peter Thomas Roth is charging for this product, you'd be better off paying extra for prescription Latisse, which we know works (often to a very impressive extent)!

  • Fragrance-free formula will condition lashes.
  • Does not have the same side effects as prescription Latisse.
  • Lack of research proving the peptide this contains enhances lash growth, thickness, or color.
  • Expensive for a product with potentially iffy to unimpressive results.

Brand Overview

Peter Thomas Roth At-A-Glance

Peter Thomas Roth is a large but straightforward line with mostly uncomplicated formulations that, for the most part, are quite good and state-of-the-art. Unlike many product lines, most of the acne, AHA, BHA, sunscreen, and moisturizing products contain what they should to be effective and helpful for skin.

Even more impressive are the well-formulated cleansers, sunscreens, AHA products, and skin lighteners. The moisturizers have improved somewhat, and most are now packaged so that the light- and air-sensitive ingredients remain stable. In fact, Roth's packaging deserves special mention because it is exceptionally utilitarian.

After all that glowing praise, what you should be aware of are the instances of products containing potential irritants (noted in their respective reviews) as well as the products in jar packaging that contain ingredients which are sensitive to air and light.
