Treatments - Salicylic Acid
Salicylic acid is a key ingredient in many skin-care products for the treatment of acne, psoriasis, calluses, corns, keratosis pilaris, and warts. It works by causing the cells of the epidermis to shed more readily, preventing pores from clogging up, and allowing room for new cell growth. Because of its effect on skin cells, salicylic acid is used in several shampoos used to treat dandruff. Salicylic acid is also used as an active ingredient in gels which remove warts. Use of concentrated solutions of salicylic acid may cause hyperpigmentation on unpretreated skin for those with darker skin types, as well as with the lack of use of a broad spectrum sunblock.
Use in PC
K16 patient "For my calluses, I've been using salicylic acid with good results. The Rx I have is for 6% and I'd like to find something not quite so strong."
MD comment "You asked about finding a cream/lotion/gel that had a milder concentration of salicylic acid (somewhere around 5%). The 6% strength are prescription only (Rx) - so you'll need to have a doctor write a prescription for any of those. I also looked at some of the 3% creams - and found that just doing an on-line Google search will give a number of things that you can get over the counter (OTC). I included one example that I found online that is marketed for psoriasis, but should work just as well on hyperkeratotic calluses found in PC."
K6a patient "I have calluses starting to grow more on my palms. I went to the doctor and the doctor didn't know if salicylic acid would help and I am being referred to someone else. I have started riding a bike and going to the gym to lift weights."
MD comment "I think the PC web page on salicylic acid is very good and explains it well. I also think that the cause is the friction is creating the calluses and no matter what he uses to soften or reduce the thickness of the callus (such as salicylic acid), if he continues to have the friction, the calluses will remain. In fact, it seems to me that once the calluses have formed, it is more difficult to get them to regress by avoidance of friction than it is to prevent it in the first place. I would describe this to him as a balance of life issues type thing - that only he can say whether the enjoyment and health benefits he is getting from the cycling and weight lifting is worth the discomfort that the callusing brings. You could try and find some type of anti-friction gloves to use."
K16 patient "We are using Urea 40 cream and salicylic acid and my husband has worked on his calluses diligently for the last few months and it has made a huge difference."
K16 patient " I use RE Salicylic Acid 6% creme that slows growth."
K16 patient "I do not recommend salicylic acid. I was using it on one hand for a few months and it seemed to be helping but has now stoped using it and it made the calluses on my hand come back 3 times more worse then they were to begin with and I wish that I had not tried it."
