Question: I bought this air mattress to use while my new bed was being shipped from back east, the bed lost air every night and I woke up almost on the floor. I tried to send it back but it was impossible to get back into the box.

Answer: Negative


Question: I love how this product makes me look in my clothes!!! its shapes me into a perfect hourglass! i dont know if the claim that it permanantley reduces your waist after 30 days is true because i havent had it that long. my only complaints are that it is a little too short, so i still have a small bulge over the top in vthe back and i think it may be stretching out as i wear it as oppossed to it shrinking me, but overall, it is the best shapewear i have ever purchased. i love it and would recommend it to anyone.

Answer: Positive


Question: I bought this at Ulta after doing some research regarding chemical peels helping acne, and one of the sales associates recommended this product. My acne has always been pretty mild, but I wanted to see if I could get it under control better. My skin is extremely delicate. My skin actually felt great for the first few days of using this product -- balanced out my skin tone very nicely. Perhaps I should've stopped there, as after a week I broke out with HORRIBLE deep, cystic, painful acne that took me weeks to get over. The scars/pock marks they left behind were even worse. I would be wary if you have sensitive skin. Fortunately, the folks at Ulta remembered me from a few weeks prior and refunded my money. Sadly, I did almost no explaining as my face told the whole story.

Answer:
Negative
