I've been using this Ardell on my previously sparse eyelashes and brows for almost 3 weeks now and I must admit, by the 10th day, I was impressed. I actually use Lucia Essence (lash & brow treatment) first and once it's dry, which is about 5 min. later, I apply the Ardell as my mascara. Once the Ardell dries, I curl my lashes with my revlon traditional curler. The curl holds all day, and my lashes after 10 days use, look more beautiful and fuller than they ever have with regular mascara. I think it's contributed to the "cocktail" I use... Lucia/Ardell. I purchased Ardell from CVS, and Lucia Essence from Ebay after reading "rave" reviews on the EDS Forum (Essential Day Spa)... if you want to read on it, type "Long, beautiful lashes" in the search field. The Ardell darkened my brows and lashes a bit and also helped them thicken. My lashes have actually doubled with these lash/brow growth serums. I trimmed my lashes about 10 days ago so that they would grow evenly, and now the length is back, plus, my lashes are getting fuller/thicker/longer. Oh, I almost forgot... I used to have to pencil in my eyebrows because or baldish areas. Now, I don't have to anymore. My brows are filling in nicely. I'm very happy with this product in combination with the Lucia.
