    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)

    Absolutely great. I’m a repeat buyer.
    Absolutely LOVE this toner. My skin is slightly sensitive and this formula NEVER burns my face. Great exfoliation. No tightness or dry areas. Fantastic for the price and just as good or better than name brand or expensive toners. I’m a repeat buyer. Big bottle and lasts a while. I would highly recommend.

    Hard to keep on the shelf
    Yesyesyesyes Imo it's the perfect male equivalent of a Honeypot wipe. It's also rock solid for drying out oily skin but to me it's kind of expensive to use it like that. Easily my favorite out of all the Thayers tonics. The serum is also really good for converting red patches into poppable pimples which then just leave, and the sulfur cream is just invaluable as a leave-on make-up/healing combo. Thayers is good stuff man. It's a billion times healthier than benzoyl peroxide or adapalene and even SA is pretty rough on the skin in therapeutic doses. Thayers does such a good job of balancing herbs and gentle chemicals to provide a uniquely safe yet effective remedy, across the board. The only thing that was a genuine flop from them for me was the rosewater tonic, which smelled like God.

    Results!!
    I have been using this product daily for just over two years. It’s one of those things that you just put into your daily routine and sort of forget about it. I usually don’t expect to see a huge improvement with any product. I just use them hoping that I will maintain the status quo and that things won’t get too much worse. :) This past Mother’s Day, I was with my sons and grandkids. I usually avoid letting them take my picture because these darn kids always seem to catch me with an unflattering look on my face. I’m pretty sure they do this on purpose. Anyway, I must not have had my guard up quite enough because when I got home, my phone alerted, and it was pictures, of me, taken incognito. 😎 I cautiously looked, and to my surprise I couldn’t believe how good the skin on my face looked! I hurriedly scrolled back in my pictures on my phone to find a “before” picture from three years ago and I couldn’t believe my eyes. My skin looks so much better now than it did three years ago. I wondered, how could this be? The only change that I made was adding this product to my routine a little over two years ago. There is an actual noticeable difference. Now, I realize that my experience is nowhere near proof beyond all doubt, however, I’m not taking any chances. I will continue to use this product daily. It’s relatively inexpensive and my results have been great.
