LCD and Tar Home Psoriasis Treatment Tests

These treatment tests I did on myself are because I prefer more natural treatments over drugs, biologics, and other treatments with side effects. These are the best two lotions to moisturize psoriasis.


Coal Tar Solution (LCD) 20% in Aquaphor Ointment is a very safe, natural, thick ointment for skin. It is made from Aquaphor (same as vaseline, very thick) which is 80%, and 20% tar. The tar comes out of the ground naturally in a place such as South Dakota, but is sterilized and boiled down so that just extract of tar (LCD) is left. Coal Tar Solution (LCD) 20% in Aquaphor Ointment is a very old, safe ointment that has been used to sooth conditions such as psoriasis and eczema.

I hope you found this test very interesting that I've been researching. As you may or may not know, there are a number of psoriasis treatments that can be done at the doctors office versus those that can be done at home. This natural treatment can be done easily at home. These tests that I've been researching on my own are to see if it would be possible for someone with psoriasis to use various LCD and/or tar creams at home. These creams can be very messy and difficult to deal with. What I have done is taken my small lesions of psoriasis that I would normally quickly treat with protopic or another steroid, and treated them with LCD or tar. Many tar lotions (liquid), creams (not the most thick), and ointments (thickest) can be purchased online, over the counter, or even for taking baths or shampooing.

I would not know what treatment will or won't work for you. That is up to you and your doctor to discuss. The information in this piece is just what worked for me, so it is important to take that into account as you read about my experience below.

The materials needed for me to do these tests were LCD 20% in Nutraderm lotion, Coal Tar Ointment 2% in White Petrolatum, Coal Tar Ointment 5% in White Petrolatum, Coal Tar Ointment 10% in White Petrolatum, a number of sets of dark pajamas, a number of sets of dark clothes, baby wipes, and a number of sets of brown and a dark colored sheets.

The tests I did are below. Please note that at no time did these ointments or lotion cover the majority of my body. I used these treatments just on test Psoriasis lesions. As the skin needs to breathe, if I felt tired, or worn out from the treatment being on my skin too long in a given day, I would remove the treatment and shower. Test treatments I did:

  1. Treated the Psoriasis 24 hours per day on my body with Coal Tar Solution (LCD) 20% in Aquaphor Ointment. This test included spreading this ointment on psoriasis lesions and then wearing either dark clothes out and about, or wearing pajamas at home. Because this ointment is a dark yellow color, it very easily stains clothing. I found this test to be pretty effective. Each time I've done this test, after about one to two months, the psoriasis lesions that it was applied to are gone. All that is left is a stain on the skin which eventually disappears in following months. The difficulty in this treatment is that I could really smell the ointment as it is basically just tar (almost like road tar but more pure) and vaseline!. If I was out and about, others in rare cases walking near me could smell the ointment and I would get some funny looks. This treatment is also a lot of work to do. I found it important and necessary to wash and dry clothes separately that I had worn doing this test versus other sets of clothing.
  2. The second test I did was in conjunction with the first test. This test was to use LCD 20% in Nutraderm lotion on any scalp or facial psoriasis lesions. This liquid is the same color as LCD 20% and Aquaphor ointment, although not as strong. I found that it takes one to two months of using this lotion 23 hours a day (24 minus shower and dry time) to make my lesions of psoriasis disappear. It was difficult to sleep when smelling this lotion as I'm a sensitive person to smells. I did get used to it. The plus of this lotion is that one container with 960 mL goes very far. Because this is a lotion and not an ointment, it was easy for me to apply with the hands, and not as sticky as the ointment in number one above.
  3. The third test I did was to use Coal Tar Solution (LCD) 20% in Aquaphor Ointment just at night. This means that after dinner in the evening I would apply the ointment on the lesions and put on pajamas. It took a little bit of getting used to for my wife more than me, but she was okay with it after a while. I found this treatment to be less effective than number one, but still useful in maintaining and slowly decreasing the lesions. With this treatment it took me about four months to make a large solid lesion totally disappear. The drawback of this treatment is that when there was no ointment on my skin during the day, the psoriasis lesions would slowly get worse. This test I did is ideal for me since I am sensitive to medications.
  4. The fourth test I did was to use LCD 20% in Nutraderm lotion just in the evening when using Coal Tar Solution (LCD) 20% in Aquaphor Ointment at night. The results were a bit faster than those in number three. It took about two months for me to clear the lesions using this technique. It was very important to use dark-colored pillowcases since any lotion in my hair would stain the pillowcase, and sometimes could leak through to the pillow. It was also important not to put this lotion too close to my eyes as it could get in the eyes by dripping.
  5. The fifth test I did was to use coal tar 2% ointment in White Petrolatum. For this test it was not possible for me to just put on the ointment and then put on my clothes or pajamas. Because this is such a sticky ointment, it got very gooey and sticky on my skin and clothes. So what I needed to do with this one was purchase plastic wrap at Costco in large rolls, and after applying the ointment, loosely wrap those areas with plastic wrap. This not only kept the tar from getting on clothing, but it intensified the effect on the skin in a good way. This treatment was very helpful although a bit time consuming. It was more time-consuming than the other treatments in numbers one through four. What I would do is carefully apply the ointment to the lesions of psoriasis, wrap those areas with the plastic wrap, and then put on my pajamas. From what I have learned about this treatment, I did not feel I should do it 24 hours a day as the skin needs to breathe. That would have also made it hard to get out of the house. So, in this test I would put it on my skin once I'm home for the day whether that be in the afternoon or evening, and remove the ointment just before going to bed. The way I removed the ointment would be either with baby/mineral oil or baby wipes. When using baby/mineral oil, Kleenex needed to be used to remove the oil and tar. After as much as possible was removed, I would take a shower using lever 2000 soap as that is the best one I had heard of for psoriasis. Then I would go to sleep with no cream or ointment on my body. I found this treatment totally healed my psoriasis lesions in about a month and a half.
  6. The sixth test I did was the same as the test and number five but use coal tar 5% ointment in White Petrolatum. I found this treatment to be a bit strong unless I first started out for a week with Coal tar 2% ointment. But overall, it was faster acting than number five. This treatment healed my psoriasis lesions in just under a month and a half.
  7. The seventh test I did was to use coal tar 10% ointment in White Petrolatum. The test was the same as numbers five and six above, but because this tar was so strong, I needed to build up by using 2% for a week, 5% for a week, and then 10% after that. This treatment healed my psoriasis lesions in about a month.
  8. The eighth test that I did was to do test number 7, 23 hours a day (minus one hour for shower and dry). This would have meant starting out for a week with 2%, moving up to 5% in the next week, and then continuing with 10%. After a couple of days I found this test too difficult, and the tar was just a bit too strong for me. So this test, in my opinion, was not ideal.
  9. Another test was at one point during test number 7 I put on hydrophilic ointment when there was no treatment on my skin. This felt better than having dry skin, but did not speed up the healing process noticeably for me.
  10. The tenth test I did was during test number seven, when the Coal Tar Ointment was not on my skin, I used Coal Tar Solution (LCD) 20% in Aquaphor Ointment on my body and LCD 20% in Nutraderm lotion on sensitive areas of skin such as my face and scalp. This test healed the psoriasis lesions well.


My conclusion to all these tests is here. It could be different what would work best for me in one of these home treatments versus what you may choose. If you are going to proceed with a treatment similar to one of the above, I would suggest for sure discussing with your doctor first as this is just what I did. When I want convenience my choice would be just to use the LCD 20% and Aquaphor ointment ( Coal Tar Solution (LCD) 20% in Aquaphor Ointment ) whenever possible. When I want convenience and comfort, my choice would be to use that same ointment, but when it is not on the skin to use hydrophilic cream. Please note hydrophilic cream is easier to apply than hydrophilic ointment. The treatment that would be more work than this but more beneficial would be to use LCD 20% in Aquaphor ointment 24 hours a day, and when possible use LCD 20% in Nutraderm lotion as well on sensitive skin such as the face and scalp. Please note though that since tar and LCD are sensitive to light on the skin, exposing any of these to light when I left the house could burn the skin. So with that in mind I found it useful to cover those areas or not have the treatment on the skin when being exposed to sun. The next best treatment I would use is LCD 20% in Aquaphor ointment for part of the day and coal tar ointment for the other part of the day. This treatment would mean sleeping with the LCD ointment on the skin. For all of these treatments, I found it necessary that after showering there be a 20 to 30 minute wait time before applying an ointment or cream so that the skin has dried a bit from the shower water. I hope this information helps you, as it was very interesting for me to do these tests.

Below are a couple of photos showing the various jars of ointment and lotion.

LCD and Tars for Psoriasis

The above photo shows a jar on the left of coal tar 5% ointment in White Petrolatum. This jar contains 400 g, and it's the same kind of jar coal tar 2% or 10% ointment in White Petrolatum would be sold in. The second jar from the leftcontains LCD 20% in Aquaphor ointment, 400 g ( Coal Tar Solution (LCD) 20% in Aquaphor Ointment ). The bottle on the right contains LCD 20% in Nutraderm lotion, 960 mL.

LCD and Tar in Containers for Psoriasis

The above photo shows coal tar 5% ointment in White Petrolatum on the left. As you can see it is a very dense ointment. When applying to the skin, it was very cold to the touch. I found it helpful warming the jar a bit in slightly warm water for 10 minutes before using. The jar on the right is LCD 20% in Aquaphor ointment, 400 g. This photo does not contain the LCD 20% in Nutraderm lotion, 960 mL from above since you can already see that the color of that lotion in the see-through bottle is the same as LCD 20% and Aquaphor ointment in this photo.

Please note that the above tests I did were done since I have had psoriasis for so many years, and learned from patients, doctors, and nurses.

Smoking, Secondhand Smoke and Psoriasis

Can smoking really cause psoriasis?

Psoriasis is a skin disease which causes redness and inflammation of the skin. The skin appears scaly and often the individual will feel pain, soreness, itching or burning. This is a chronic disease but is not usually life threatening. People with psoriasis can go through the same experiences of those with severe diseases. For some time, psoriasis has been linked to different causes. One of these causes is smoking. For many years there was no scientific evidence until recent years, such as the Nurse Health Study II publication. These are the best two lotions to moisturize psoriasis.

Smoking and drinking top the vices of people in our society. Even in high school, teenagers start to experiment with these kind of fixes. Some will quit while others die due to ailments caused by smoking or drinking. In the United States alone, many of the population die due to smoking. The tobacco in cigarettes contains more than 4,000 chemicals that are toxic to the body. Every puff from a cigarette brings the smoker one step closer to a risk of illnesses of the throat, mouth, esophagus, heart, lungs, skin and others.

In 1985, O'Doherty and MacIntyre brought up the relationship of smoking and palmoplantar pustular psoriasis. Since then, many more studies have been conducted to prove this assumption.

One of the groundbreaking studies proving this case is the result of the Nurse’s Health Study II. In 1989, 116, 608 female registered nurses completed a questionnaire as an initial survey for the research. After 14 years of continuous follow up, out of this group of women, 887 had an occurrence of psoriasis. Researches found out that psoriasis incident happened to smokers, past smokers and those breathing secondhand smoke. As such, the result of the Nurse’s Health Study II supported the connection of smoking being one cause of psoriasis.

According to the results of this “ongoing longtitudinal study”, the risk of having psoriasis increases if one taking in smoke reduces gradually instead of just stopping. Note that quitting only reduces the risk but does not erase the risk of damage done. The study of NHS also concludes that even in the event one stops smoking, it takes 20 years to decrease one’s susceptibility to the risks of developing psoriasis. Passive smoking can also trigger the risks of psoriasis. Women smoking during pregnancy increase the risk of their child to psoriasis and children exposed to a smoking environment face the same chances. Another result of the study is that between men and women, women are slightly more prone to psoriasis.

What could be the agent in smoking that increases the risks to psoriasis? According to experts, the toxins in cigarettes affect the biological level of those breathing smoke. In fact, because of these toxins, the immune system decreases various functions. A body process greatly affected by this is the skin cell growth. With these toxins in the body, the skin cell growth slows down. According to Luigi Naldi, M.D, who led an Italian case control study on smoking and psoriasis, the nicotine is the probable cause for the changes in one’s immune system. The nicotine is believed to hinder skin cell growth, the same reason premature aging is another downside of smoking. The more years an individual smoked, the more one is prone to psoriasis.

The advice of health professionals is to quit smoking, do not breathe secondhand smoke, and don’t start smoking. Health professionals continue to educate patients with psoriasis to avoid smoking, especially since the correlation between the two has already been proven. Studies have provided overwhelming, unquestionable scientific evidence so that they can educate and help others.

People with psoriasis deal with years of experimenting with medications, experiencing scrutiny from other people, and suffer from loss of self confidence and self esteem. The red patches and scaly skin is not a pleasant sight for anyone, including the person with psoriasis. For smokers or those breathing secondhand smoke, it is clear that removal of smoke can only help their situation. It is also good to keep in mind that smoking can not only bring about psoriasis, but also other life threatening illnesses sooner or later in life. The worst part would seem to be the dangers inflicted upon one’s own health, but the fact that secondhand smoke can cause psoriasis and other diseases for one or many others near the smoker is something no one wants to cause.
