No! According to Elta MD this store is not an authorized dealer and obtain their products illegally.

I would not do business with this company again.

As far as I can tell, the many products I've purchased from Dermstore have been real products. I've had a couple problems with some products. For example, the Four Truffles butter lotions looked as if they were deficient and another lotion product I bought was expired. I took iPhone pictures of both, and the company immediately responded. My credit card was paid back and they sent replacements, without me having to send them back. But everything seemed to be the real thing. Except for that one order with those 2 lotions and an earlier order with some soap that was crumbling, everything I got was in perfect shape. With both orders, I sent iPhone pictures of the problems and was reimbursed and sent either credit card refunds or replacements without having to take the trouble of sending the items back. I believe that what I was sent was the real thing. I hope this helps you.
