Rated 4.5 out of 5 by 52 reviewers.
Rated 4 out of 5 by Great Soap I use this on my face and body and I feel very clean afterward. Also the subtle scent is great. I wish they would make a body far with a higher sulfur content. December 8, 2015
Rated 2 out of 5 by On to the next thing... This smells so bad once it starts to lather and I would've gladly kept using it anyway if it worked. Sadly, it did not help with acne or even blackheads. I also found it to be drying. Luckily, it's very inexpensive to try out (the bar probably could last you a year. maybe longer.) and it did not make matters worse or at least I hope it didn't. *I gave it about 3 months for reference. November 25, 2015
Rated 5 out of 5 by Most acne products dry out the skin. This doesn't! And it works! Which, for the price, is amazing. I've always had troublesome, acne prone skin that is oily but flaky (not sure how that's even possible. My skin is THAT annoying.) I cannot say enough positive things about this simple bar of soap. I will never go back. August 26, 2015
Rated 5 out of 5 by Great! Keeps me from getting shoulder and back breakouts due to sweating. July 19, 2014
Rated 4 out of 5 by Keeps breakouts at bay This soap has definitely helped control acne breakouts for me. I find that it is gentle and lathers well. The only downside is the smell but I don't notice it as much anymore. Great product, and is very affordable. Thanks Grandpa! April 18, 2014
Rated 5 out of 5 by goo soap I bought this soap for my 11 year old who had been experienced some blemishes. This definately helps dry them up very quickly. I began using it to help balance my own skin and help reduce oil on my skin. I did realize you cannot "scrub" without causing some redness and irritation. Washing with hands or softly with a cloth works best. March 16, 2014
Rated 5 out of 5 by AMAZING RESULTS! My 18-year old daughter has had awful acne for years on her face and neck. She had tried a series of sulfur washes and prescription creams and nothing worked--every other sulfur product dried her face out even though she has very oily skin. I got this soap for her because I read the great reviews. After one week there was a DRAMATIC difference in her acne. After three weeks her face is totally clear, is not dry and looks beautiful. This is the ONLY thing that has worked! I HIGHLY RECOMMEND THIS SOAP! Thanks Grandpa! February 21, 2014
Rated 5 out of 5 by very effective I have been using this soap for about 3 weeks. I have noticed a marked improvement in my skin. No blemishes any longer and pores almost completely clear. Highly recommend. February 5, 2014
Rated 2 out of 5 by Wouldn't purchase again I have combination skin with pimples mostly on my forehead and chin. I have been using this soap for a couple of weeks, but it hasn't cleared up my pimples at all. The soap hasn't made my skin any worse but it definitely hasn't made it any better. January 4, 2014
Rated 5 out of 5 by Grandpa's soap Very happy with this product. I tend to break out but I've noticed a great improvement in my skin. My skin is pretty much clear now. I've tried a lot of products and this seemed to work the best. I use Swanson's clear complexion cream too. So not sure if its a combination of the too. November 2, 2013
Rated 5 out of 5 by Best purchase ever I have tried several different cleansers and facial products but this has been the most effective product to treat blackheads and adult acne. Works very fast, saw results in two days, it immediately calmed the redness and pain of pustules of rosacea. Love this product, and it is so cheap, it does have a strong sulfur smell but it is worth the minor inconvenience. August 2, 2013
Rated 5 out of 5 by Great Bar Soap My dermatologist recommended I use a mild sulphur bar soap on my face due to acne rosacea. My skin is so sensitive to soaps, especially bar soaps. Even Dove burned like crazy and left my skin overly dry, cracked, and extremely irritated. I told her about my reaction to all bar soaps, but she said to try a sample bar of her brand. Well, I was determined to prove her wrong. I was wrong. I tried it and was amazed at how nice my face felt. It was not dry, red or irritated like every other bar soap I have ever tried, EVER. I could not believe the results. My problem came in when it cost over $8.00 - for 1 bar! I just knew there had to be a cheaper version of a mild sulphur soap on the market. Swanson came to the rescue again. Thylox Acne Treatment Soap with Sulfur from Grandpa Soap Company is just a fraction of the cost of the dermatologist's brand and every bit as effective. My skin feels clean, soft, and smooth after washing, with no irritation. It seems to be effective on my oily, acne-prone skin. Breakouts are much less frequent and cleared up more quickly. The only drawback is the mild sulphur smell. However, it did not take long to get used to the smell and now I don't even notice it. I love this soap and will use it forever! July 27, 2013
Rated 5 out of 5 by Soap that really Works I have used many products for my acne but this soap is the best and cheapest treatment I have ever had. I wash in the morning and evening with it and my face is never dry and the acne is totally under control. I am so happy with the product that I ordered about 5 bars to share with my family and friends. June 23, 2013
Rated 5 out of 5 by Great acne control I'm in my early 40's and suffering from acne for the first time in my life. I had been using Burts Bees acne system with fair results when I saw this bar and decided to try it because it was so affordable. Using it twice a day, my acne has been reduced from several breakouts weekly to one or two a month. When I do have a breakout it's dried up and healing within a day so I LOVE this product and I will most definitely purchase it until my acne resolves itself. November 7, 2012
Rated 4 out of 5 by Slowly but surely This is working on my son. The progress is slow, but it is not harsh and nothing else we have tried has worked. Reducing redness and slowly clearing up bacne chest, and arms. July 19, 2012
Rated 5 out of 5 by Silky Skin Sulfur always stinks a little, but this soap leave your skin very smooth and silky. Also, helps with breakouts. July 7, 2012
Rated 4 out of 5 by Feels very nice. Acne seems to be clearing up much better while using this. Not sure about blackheads as I haven't been keeping track of them. It goes on very easy with help of a little water. I just dab a few drops of water on the soap and rub it on my face. I then wet my hands and work it into the skin. I leave mine on for 5-10min and sometimes I might even forget it's even on. It comes off very easy and makes my face will very good. So far so good. June 19, 2012
Rated 5 out of 5 by The only thing that worked Works well on my 16yr old son whom tried Proactive and everything else. This really works. May 19, 2012
Rated 5 out of 5 by wonderful this is a great product. my face looks better after each use. it minimizes redness and irritation, helps heal, doesn't overdry and makes the little bumps that eventually turn into full blown pimples slowly vanish. i will never be without this :) May 11, 2012
Rated 5 out of 5 by Sulfur is great for Acne this is a great price for a product to add to your acne regimen. I keep mine in a clean soap holder and remove it from the shower when I am done so the water doesn't destroy it! April 4, 2012
Rated 5 out of 5 by I love Grand Pa! My grand daughter had black heads on her nose that looked not only ugly but painful. Nothing I bought helped. I saw Grand Pa's soap and decided to try it. I am so glad I did. All the black heads are gone. Thanks Grand Pa March 21, 2012
Rated 5 out of 5 by It really works!! You will see and feel the difference in a few days.i recomended to my sister in law and I will buy more!! Thanks February 29, 2012
Rated 5 out of 5 by Good soap Simple to use lather and rinse. When skin is oily / greasy I leave it on longer. If it dries my skin out, I rinse it off quicker and use less. If I use this soap with other acne treatments = rash. I was very surprised at results for less than $5.00 a bar. January 18, 2012
Rated 5 out of 5 by Really helps Please keep this soap! It really helps. October 18, 2011
Rated 5 out of 5 by Helps combat acne This soap has reduced acne flare ups. Seems to leave skin feeling soft after use also. It does have a strong sulfur smell, which lingers after use. August 24, 2011
