Amazing how fast it works
Item Package Quantity: 1
This works so much better than the prescription cream I got from the doctor. I thought 40% was the highest available. Ease of use and it goes exactly where it's needed. Saw improvements after the second day of use.

Amazing cream to restore cracked skin!!
Item Package Quantity: 1
Cracking of my feet is not the problem. This has been the only cream I found that restores my cuticles!! My right thumb constantly stays dry and ugly. The convenience of applying like a ChapStick is wonderful. and allows me to grab and apply frequently. My cuticle has finally become soft and pretty. :) (Highly recommend)

Awesome!
Style: Blemish Clearing Toner, Size: 12 Fl Oz (Pack of 1)
Love this product! I've used witch hazel for a long time as a toner and to help keep acne under control. Thayer's is the brand I've always used and loved. This one is specific for acne and blemishes, so I thought I'd give this blend a try. There is a slight fruit loop smell (it fades quickly!) and I feel like it's slightly sticky (which is not how plain witch hazel feels) but that also goes away as it dries. I use this anywhere on my face, but especially where there are blemishes and acne. It works well, and doesn't seem to adversely react with my rosacea , which is a plus! I let it air dry, then apply my favorite moisturizer. Results come quickly, and I love how clean and fresh and skin feels!
