Spectral.LASH® is an ophthalmologist-developed eyelash-conditioning serum that supports the appearance of longer, visibly denser, thicker, and fuller lashes, formulated with unique key ingredients of the highest quality and proven efficacy. This formula has been encapsulated in our proprietary Advanced Nanosome Delivery System® which offers higher penetration for maximum results. Our proprietary easy-to-use applicator dispenses a precise dosage to each lash, improving the bioavailability and avoiding cross-contamination.
