I had been living (ignoring) this condition for over 30 years. KP is hereditary, and its a skin condition without cure. Just a couple of months ago, my sister had mentioned, she had used something and it made the bumps go away. My quest had then been rejuvenated.
What I've found thru more research that worked for me is... exfoliate really well using a buff puff or something similar. (loofah, scrubbing mitts, scrubbies don't work as well) something that can scrub finer is better. You don't have to use any AHA products but perhaps it'll help but since you wash the stuff off anyways, very little tend to stick. The most important ingredient... coconut oil! I use the solid coconut oil from a local E. Indian market. You can get it at almost any Indian market. It is less than $5 for 250ml jar. The one I bought was Kissan. It doesn't have a smell at all. I use it after exfoliating while I'm in the shower. I don't rinse it off tho. I use the leftover on my hands to moisturize my legs and my hands and then I exit the shower. By the time I leave the shower, my arms have absorbed all the oil and my arms are not oily at all. The results are immediate but you have to be consistent. I do this EVERYDAY without fail since I've worked it into my morning routine. There are other forums regarding KP. Many have recommended coconut oil as well. If you are unsure, go buy the cheapest one. Mine is just pure coconut oil, made by Kissan that comes in a clear jar and costs less than $5. I've found organic ones for more than double the price of the one I am using but the cheap one works why pay more. I did put some of the oil into a plastic baby food container to have in the shower. Oily glass jars and bathtubs are not friends. If you don't want to use it in the shower, use it when you get out. I use it in the shower so I can rinse my hands. My sister uses it when she gets out... no difference in the results.
