I was extremely skeptical about this product. I had received a free bottle to test, and trial. During quarantine I haven’t been doing my make up much but I religiously continued my nighttime skin care which included this serum. After about two months of using it every night, I finally went out for a weekend and applied my make up routine. I was absolutely blown away after putting on my mascara. I couldn’t believe The length and wispy-ness of my lashes! Yes. Its works and works well!
