I love the product, but like the tube on the sample better than the dropper style on the purchase product. I end up not using the dropper because the product is too thick for the dropper. I just place a small drop on my hand and use it. Using the dropper is clumsy and annoying. Also the sample lasts quite a long time due to the style of tube

Wonderful serum, smooth and easy to use. My only complaint is the bottle. It's impossible to see how much is left in it. So ordering new product gets tricky.

Although I don't have much experience in comparison with other similar products. After using Blue Therapy I dont feel the need to search any further. This product leaves my skin felling moisturized without that thick sticky, oily waxy feeling. My skin feels healthy, more youthful and relieves me of puffy eyes, I plan on making this product a staple in my skin care.

It works. My age spots are fading and my skin feels smoother.

Have been using this products for 6 months now...worth the money...
