Vibrating Mascara – really worth the purchase?
Anybody tried it? Is it as good as they say? And if it is, which is the best? So far I only know of 4 that exist:
Estée Lauder – TurboLash
Lancôme – Ôscillation
Prescriptive – Motor-Eyes
Maybelline – Define-A-Lash Pulse Perfection
If I’m going to buy it, I want the best. So what does everybody think about it so far?
to be honest i dont see a difference when i wear the virbrating. dont spend the money more money on a vibrating mascara when you can get the same results from a normal mascara!
