I've used both masks and I find the Peter Thomas Roth one to be better for my sensitive skin. I found the DDF one to be very irritating, which countered any good effect it had (no visible results) and had to return it. Even as a spot treatment, I felt tea tree oil was better for my skin.

On the other hand, I really love the Peter Thomas Roth one both for how it cools the skin down and clears it. My skin was very, very smooth after using it.

I miss-typed my last message. It is $9.50 an ounce for the DDF product.

Here's a quick comparison. Keep in mind, it's not just about price...

DDF - $38
SIZE: 4 oz
Ingredients: Water, Bentonite, Propylene Glycol, Talc, Kaolin, Titanium Dioxide, PVP, Diazolidinyl Urea, Glycerin, Fragrance, Methylparaben, Aloe Barbadensis Leaf Extract, Sodium PCA, Allantoin, Propylparaben, Prunus Amygdalus Dulcis (Sweet Almond) Oil, Benzyl Alcohol.

Peter Thomas Roth - $40
SIZE: 5 oz
Active: Precipitated Sulfur U.S.P. 10%. Purified Water, Bentonite, Kaolin, Propylene Glycol, Glycerin, Aloe Vera, Zinc Oxide, Eucalyptus Oil, Polysorbate-20, Titanium Dioxide, Diazolidinyl Urea, Methylparaben, Carbomer 940, Sodium Hydroxide, Propylparaben.

This all may mean nothing to you - but honestly - I use the Peter T Roth Mask and think it's a great product. $2 for an extra once is a deal if you average it out...
DDF = $6.50/ ounce
PTR = $8.00/ ounce.... you're basically getting an extra ounce for $2 when comparing the both of them...

Yes like AJS23 said they are owned by Procter and Gamble and test on animals which is part of the reason i bought the PTR sulfur mask. Also with the Peter Thomas Roth mask you get 25% more for only 2 dollars more. It's definately a better deal. If you buy the DDF mask you are paying $9.50 an ounce with this mask you are paying $8.00 an ounce. It works very well. I give it two thumbs up :)

spend the money! This is cool and refreshing and works great at ridding impurities and for on the spot blemishes!

I've used both and prefer DDF. It's far less irritating.

peter roth!!! the cooling masque is amazing and although it's so lovely... :)

I wouldn't buy either of the masks you mention. Proactiv's Refining Mask with 6% sulfur is much better at getting rid of pimples and can easily be used overnight where the PTR product can't.

I haven't used DDF, but sulfur is supposedly meant to treat cystic acne (and this mask works very well for mine). It does a great job, I would highly recommend it...and you can also use it as a spot treatment at night.

I was trying to make the very same decision, then I found out that DDF was owned by Proctor & Gamble. Proctor & Gamble is one of the largest animal testing offenders in the country and I therefore do not purchase any of their products. Peter Thomas Roth, on the other hand, is a cruelty free company. That made the decision for me.

I have used both of these products, but I'm not sure how to go about answering this. Each of these products have their differneces. The DDF masque is less potent in scent and a little more emollient, whereas the PTR masque is very strong (due to menthol) and perhaps a bit gritty. However, I still liked both products. I think you should base your choice on skin sensitivity. The PTR masque is very, very stong! If you use it as a spot treatment, there will no longer be a blemish. However, it left a red mark, because of the potency of the masque. If you use PTR, don't leave it on any longer than 30 minutes. I hope this helps! (:

Using as a masque once each week, and as a spot treatment at bedtime works well for our family. We tend to have serious break outs, complicated by extremely sensitive skin.

I would suggest only using for 10-15 minutes every three days or so. Using too often or for too long might stimulate too much oil production and make break outs even worse (I over cleanse my skin sometimes and that's what happens to me). If you're getting stress break outs, maybe you could use the mask while doing 15 min. of yoga : ) Hope this helps!

It's okay several nights in a row, but you should see improvement. If you don't see improvement then vary treatment - try a few nights of this and then a few nights of salicylic acid. Also wash with a benzoyl peroxide wash. If you still have problems, try to avoid dairy products and soy. Hope this helps!

I think it should be used once a week, not more than that.

I use it every other day but I think the directions say not to leave it on more than 10 minutes. I think if I doesn't dry out your skin too much you can use it as a spot treatment.

I had some pretty congested skin on my forehead from using a silicone-based primer and used this to help clear it away. I probably shouldn't have, but I used it overnight as a spot treatment every night for a month, BUT by 30 days later, my skin is extremely clear, just a little on the dry side. every other day would probably be the best way to go about it, but if you want to speed up the process by using it every night, make sure you use a heavy duty moisturizer right after to balance out your skin.

my cheeks break out too and i use every night! i cleanse, tone, then apply the sulfur masque!! wipe down and before bed i just apply a little to my problem areas

Use your best judgement. I use all over 1-2 times per week. T-zone 1-2 times per week. Spot treat daily (in the mornings). Just make sure you're paying attention to how dry your skin is getting while using it.

I use it every night as a spot treatment for problem areas. It doesn't dry out my skin...I have combination oily and dry. If I am breaking out on the dry parts, it don't use it there as a spot treatment, instead I use as directed. It's worked so far for me....when my skin is calm I use it every 5-6 days.

I had the exact same problem. My cheeks were breaking out, and I figured that since the ingredients seemed harmless I would use it overnight everyday. It didn't make my skin worse, or burn my skin or anything. It actually helped my pimples a lot. I now have a couple of light scars (that's my fault, I kept poking at them), but the sulfur mask even helps with that. If I use too much, my cheeks can get a little bit dry, but after not using the product for 2 or 3 days, the dryness goes away. I've been using this product for over 3 years, and I've kept it on overnight before (despite what the directions say) and it has helped my skin.

Sulfur content here is 10% and is the active ingredient.

Apply this mask all over and leave on for an hour. Remove with lukewarm water by applying a moist washcloth over face for a few minutes then wipe of with washcloth. If you have mod- severe acne use everyday for a week. Apply peter Thomas Roth aha/bha acne clearing gel after mask everyday(get sample) it works! I have tried every product out there for 20 years and this I'd the first time my face has been clear.

This one is very strong. I originally applied it all over but found the fumes irritated my eyes. Now, I just spot-treat - only put it on a breakout and not close to the eyes.

all you have to do is just take it with your fingers and put it on your face. just cover everything and make sure it's all about the same amount.

I just take it right from the jar and apply a thin amount with my fingers all over my face avoiding the eye area.

You can use the mask as a spot treatment--applied directly to blemishes or problem areas--or as a full facial. Apply liberally to clean, dry skin. Let the mask dry before washing off; if you have sensitive skin, don't leave on for longer than 10 minutes. I will often leave it on for hours or overnight if I've got serious blemishes to deal with. Otherwise, a quick facial works too.

Rinse with luke-warm water and your fingertips (gentle). Pat dry. Feel refreshed! Aaaah. :)

try introducing it to your skin as a spot treatment first. wherever there are blemishes (or even some post-acne scars you want to get rid of), get some of the product on your finger and dab a thin (or thick) film on top to cover it. if I use it as a spot treatment, I usually leave it on overnight, but leaving it on for a good fifteen minutes is good, or at least until it's fully dry is when you can wash it off. remember to be gentle when you wash it off, and when you feel comfortable enough with it, you can us it as a mask. just don't over-do it and use it every day. oh, and make sure to moisturize after every use.

you can use it on the entire face and once you feel it turn to dry you can rinse it with warm water!! OR you can apply it at night, before bed, to your ZITTY areas!! It's awesome

a little of this product goes a long way. take about a dime's worth and smooth it onto your problem areas. it will be very cooling to your skin. let dry and then rinse of with water or wet washcloth. keep away from eyes!!!

You just massage it on your face, avoiding eyes. Let it dry (about 15 mins), and then rinse with water. I hope you like it.

if you have dry skin do not leave it on for more then 5 min. You can use it as a spot treatment or smear on your whole face. I would not leave it on for more then 15 min, it really works.

My skin is pretty sensitive - i.e. I swell up if I use benzyl perioxide. This works fine for me if I don't get it near my eyes or right under my nose. I just leave it for about 5 minutes even though it calls for longer. It really works for me to clear up acne.

YES !

I think it's too strong. I like Boscia products better - they're less iritating.

This masque doesn't make your skin look raw at all, it just makes it smoother and more radiantl

Yes!! My skin is sensitive and acne prone. This mask doesn't agitate my skin on either point. It's just soothing n great on my pores!

I have a mild form of rosacea, and flush easily. This mask doesn't cause flushing for me, but I do find it irritating to my eyes if I get it too close to them for too long. If you're close to a store, see about getting a sample before plunking down your hard-earned cash!

If you're worried about irritation, I'd recommend trying a sample of the product to begin with. Just put a little bit on a blemish or problem zone, and see how your skin reacts before attempting a full facial. Although I do not have super sensitive skin, the friends I do have with sensitive skin tend to experience a burning sensation with most clay/acne treatment masks, so try a sample first. Personally, I don't experience any "burning", but a slight cool tingling, which is pleasantly refreshing.

I have sensitive skin, and this mask is in no way irritating. It is quite the opposite - very soothing.

I have sensitive combination-oily skin and have been using the sulfur mask for about two months now and haven't had any major problems. it's very gentle, the smell is close to how Noxema is, it doesn't sting (even on open blemishes) --- I would only suggest that you use a really good moisturizer after using it, and using it every other day or every two days if your skin is extremely sensitive.

yes it is perfect for sensitive skin!!

Hello! Though I really like the DDF mask, I have to say that I like this one a little bit better. The texture is nicer and I think it works better. I've switched to this one. Hope that helps!

Truthfully I've found them to be very similar. They are both clay based with 10% sulfur. Both are fantastic, although I tend to use a lot of PTR stuff in general.

I've tried both (and the Decleor sulfur masque) and I always come back to the PTR one. I think it's just a great product and I've been using it for over a decade. I think it's more of an effective treatment than the other sulfur masques and more "medicinal" if that makes sense. However, it isn't quite as nice smelling as the others. Small price to pay for good skin, tho!

sorry never used DDF but this stuff rocks for oily and ance prone skin. my skin has never looked better. i have been using this for less than 2 weeks and acne that i have battled for 30 years is gone. a little goes a long way. this should last around a year and well worth the $$$$

I prefer the DDF product based on the smell alone. If eucalyptus doesn't bother you, then the peter roth one is probably better. I find them to be equally effective. TPTR is a little easier to get off, but I always use a scrub after a mask so that doesn't matter to me either. While neither smells good (they are sulfur masks afterall), the DDF one is less offensive to me.

I prefer the PTR. It goes on smoothly and you don't have to scrub to get it off.

I have had my jar for about 2 weeks and it's almost as if I've barely made a dent and I have been using it often! I spot treat almost every night and have only scraped off the surface it seems like. I apply the mask liberally as well. The jar will last a very long time!

it will last you a LONG time if you use it correctly, you really dont need a lot. Just smooth on a thin layer and the product works like a charm. As long as you don't glob it on and waste it, you will have many uses! I've been using it 2x a week for a few weeks now and havent really made a dent in the jar.

I've used it as a whole face masque five or six times, and as a spot treatment five or so times, and there is still at least 4/5th of the jar left.

This product lasts me about 5-6 months and I sometimes use it up to 2-3 times a week and as a spot treatment.

I've been using this product for nearly 20 years. My facialist is the one who first turned me onto it when I was 20 years old. She told me to apply a thin layer (not a thick one as directed) RIGHT before I jump in the shower. Then, keep it on in the shower for the entire time and rinse it off at the very end before getting out.

Not only does the steam help the mask to work better, but it never dries out the skin this way AND it makes the tub last at least three times as long as when I had been using it as directed.

I would not recommend doing a thin layer without the steam of the shower, though, since it can be drying.

It is somewhat effective at getting rid of blackheads, but not a significant effect. A blackhead strip is more effective at instantly getting out blackheads. I have had this mask for 2 weeks and am not sure I see much of a difference with regards to the blackheads.

Yes. It helps slough of skin cells and dry the acne. Allowing the blackhead to either diminish or be extracted.

I don't really have any black heads, well maybe a few.. but this mask is amazing and my face has cleared up so well! I would definitely think that this would shrink or diminish your black heads after a few uses. :) Hope this helped!

This mask irritated my skin, I dont think you should be going through a purging process. I think you should stop using it.

If it is breaking you out after 3rd week, I would recommend you to stop.

I never had any break out from this product. I bought after reading that one of the ingredients was sulfur. I heard that your skin will either like or not like sulfur. Have you used any other sulfur products before that your skin liked?

For my skin I would never consider keeping this mask on overnight. It tends to dry my skin out and if you have similar issues with dry skin, this would cause serious dryness. Just my opinion though.

I'm sure you could use this as an overnight treatment, but you might want to use a towel over your pillow...like other sulfur masks I've tried, it starts to flake off when it's dry.

I don't think you can use it overnight...
