I don't think this mascara is authentic. It is super flaky and dry, I couldn't go to Sephora though and I really needed mascara so I bought this one. I couldn't return it either because I was going out of the country. Anyway I just got the YSL Babydoll and used my old original Singulier mascara's brush in the baby doll formula.
I love YSL Singulier mascara it didn't flake, it applied really well and smelled amazing. Not sure why Sephora doesn't carry it anymore :( but I will forever clean my brush from the Singulier mascara and use it with their other formulas.
I bought this mascara on amazon as well, but I don't like it. It takes about 3-4 hours for it to come down under my eyes... i have dark circles by the time i go to lunch. every time. this is very irritating
