Do you put a concealer on top?

Yes, the optic crystal serum serves as a wonderful base to keep the concealer from looking dry and increasing the look of fine lines.

How many times a day should i use it (am & pm)?

Once a day or even ever other day…..

Is this real? why is it half the cost of the same product on the manufacturer's website?

I was directed COSMEDIX's Amazon store to purchase the Opti Liquid Crystal Eye Serum ($95) by using a link in an article I read about it on the InStyle magazine website. The article also included a link to the COSMEDIX's own website as well (price was $104 there). I don't believe that InStyle magazine would be publishing links on their website to Amazon sellers that were selling counterfeit (read ILLEGAL & DANGEROUS) products. Also I'm quite sure whenever those type of review/promotional articles are written about products on these websites - the companies are very much aware of the article being published and any links to their products in said articles. So I wouldn't worry about the legitimacy of this particular product. Hope this helps!!

How many applications are in the tube

I use this product at bedtime and 1 tube lasts about 4 months. It only takes a very small amount (less than the size of sesame seed) to get excellent results.
