Spectral Lash, a cutting-edge treatment from DS Laboratories, is clinically demonstrated to make eyelashes appear 25 percent longer in just two weeks. Many users also enjoy greater thickness and density. Spectral Lash utilizes a breakthrough peptide complex, not a glaucoma drug like bimatoprost. Peptides work by stimulating the expression of keratin genes and improving overall eyelid health. These developments represent the most recent efforts in biotechnology, advancing the safety and efficacy of eyelash therapy.
