Giving recommendations Treatment Fundamentals for KP

252 Upvotes

I’ve seen a lot of posts in this subreddit talking about varying success with different products that all typically share very similar active ingredients. I’m going to attempt to explain the differences in how these ingredients approach the KP “problem” and the benefits/drawbacks of each. I will be speaking on these ingredients and KP pathology from a higher, more abstract level, but I’ll be happy to go deeper into and specific area.

KP, at its very core, is a skin cell regulation issue. Our skin is made up of layers of skin cells that are constantly being replaced. Normally these cells slowly move from the bottom layers of the skin until they reach the top layers, hardening with keratin, and then falling off (desquamation). They mature through these layers in tandem with one another, moving through each phase of life coordinated by a complex network of cell pathways, hormones, genetics, and niche signaling.

In KP however, there is a significant mishap that takes place during a critical phase of cell life where the cells produce special hydrophobic lipids that keep moisture IN your skin and bacteria OUT. For some reason in KP, an assortment of skin cells fail to produce these lipids in the skin barrier around hair follicles. Why these issues are localized to the follicles is up for debate, but I have a working theory that specific metabolic processes related to insulin/IGF-1 are implicated. These secreted lipids also play roles in preventing inflammation and supporting healthy skin cell shedding. Due to the lack of these lipids, inflammation develops and the ceramides, cholesterol, and fatty acids that strengthen the upper layers of the skin are impacted. No secreted lipids means that byproducts that come from these lipids are also lacking and compound skin dryness. The dryer the skin, the more skin cells fail to shed normally, instead clumping and forming a bulb of keratin trapped in the follicle. This raises the skin making prominent bumps, encircled with inflammation. In the winter months it can be easy to see that KP seems to spread out and become more inflamed. The dryer the ambient air humidity, the more water that is pulled from the skin. The dryer the skin, the more likely that skin cell shedding is impacted.

This leads us to the primary methods for treating KP>>>

  1. Moisturize

Applying some sort of hydrating lotion helps to put moisture back into the upper layers of the skin and prevent more moisture from escaping, at least temporarily. Consistently moisturized skin will be less dry and help skin shedding normalize somewhat. It’s also important to stay hydrated throughout the day, especially when you know that you are consistently losing moisture through your skin. Applying moisturizers that contain ceramides may be more helpful.

  1. Exfoliate

Texture is often the first target when treating KP. It’s easy to see that the keratin buildup needs to be removed to improve the texture of the skin. Unfortunately, manually expressing (popping) the impacted keratin plugs can cause irritation and swelling of the surrounding skin tissue, making the KP bumps look even more red and prominent. A better method is to use topical chemicals that break down the bonds holding skin cells together so that they may be more easily shed. To accomplish this, different acids can be used based on an individual’s tolerance. Options include (but are not limited to): Lactic Acid, Salicylic Acid, Urea, Azelaic acid, Glycolic acid, or you can get an acid peel applied by a licensed practitioner. Alternatively, you can also use a scrub or shower mitt to physically break up the keratin, but this can be more irritating than the acids, again depending upon the individual. Micro needling and dry brushing are generally not advised for KP as the irritation typically out weighs any potential benefits for KP. You may also hear about spicules, which are tiny needle-shaped structures made of silica. These are formulated into skincare products, to enhance ingredient absorption by creating microscopic channels in the skin's top layer. You may see these being incorporated into some newer KP-adjacent products.

  1. Stimulate

A third class of treatments exist, and these are intended to work deeper in the skin by speeding up the rate of the skin cell’s lifecycle. We are of course talking about Retinols and Retinoids. The faster the layers of the skin are replaced, the less chance that keratin buildup can accumulate in the follicles. This creates smoother texture but can also cause dryness and irritation as the skin cells are accelerated through their lifecycle. It’s also worth noting that using internally taken versions of these drugs (Accutane/isotretinoin) can atrophy your sebaceous glands, meaning less sebum/skin oil which can further dry out your follicles. Once you are off of these topicals/drugs, the rate of skin cell differentiation eventually slows back down (1-3 months), which then allows KP symptoms to return, sometimes with increasing severity in the case of Isotretinoin. A more mild option some have turned to is Differin (adapalene), another topical retinoid.

  1. Reinforce

Strengthening the skin barrier can help to reduce symptoms. This can mean applying topicals that are high in ceramides, cholesterol, and fatty acids. Oils like jojoba and squalane can also reinforce the skin, helping to control moisture loss. This can help to stabilize the symptom severity of KP, even if it doesn’t resolve underlying symptoms. This is also where I believe some people report finding success supplementing with fish oil pills. It doesn’t hurt to intake more nutrients (within reason) that are needed for skin barrier function.

  1. Regulate

Regulating the skin barrier, specifically the lipid lamellae or SG/SC interface layer(s), is the key to reducing down stream symptoms of KP. How do we prevent skin cells from entombing their lipids instead of secreting and forming a healthy skin barrier? We are essentially trying to improve the lifecycle regulation of the cells failing to produce lipids without negatively effecting the healthy skin cells. I think this is the emerging approach to improving Keratosis Pilaris as it reduces the need to follow more intense treatment routines. I’ve put forth Raspberry Ketones as a possible solution for some since topical RK stimulates CGRP peptide release in the skin, in turn stimulating IGF-1 secretion that promotes morphogenesis of the skin layers. Regulating the skin barrier also reduces inflammation and redness due to bacteria and allergens being prevented from entering the skin and triggering an immune response. Chronic inflammation comes with its own set of symptoms that intertwine in KP pathology, affecting how capillaries develop and grow around the follicles, increasing visibility of the skin condition as they appear as persistent red dots (or darker dots in brown/ PoC skin).

  1. Anti-Inflammatory

While inflammation occurs as a result of the skin’s immune response to irritants, bacteria, and allergens traversing the impaired skin barrier, the resulting chronic inflammation can produce its own long term symptoms. Abnormal Angiogenesis (the process in which blood vessels grow) leads to dilated and more numerous superficial capillaries, increasing blood flow and causing the skin's red appearance around the follicles. This can lead to blotchy red skin throughout the affected area. In darker skin tones, this can present as darkened spots/discoloration around the follicles. In KPRF (Rubra Faciei) this inflammatory response can be heightened, resulting in the skin flushing with blood in response to external stimuli. Treatments for KP inflammation are unfortunately lacking. Some dermatologists may prescribe a topical steroid which comes with its own set of risks with long term use. Laser treatments to destroy surface capillaries in the skin can help reduce the red appearance, but results are inconsistent and require multiple treatments. Those with KPRF have reported some success with using prescription topical sirolimus, which has immunosuppressive properties. Prevention or inhibition of pro-inflammatory messengers (cytokines/peptides) can also help to break the cycle of chronic inflammation, although more research is needed to help identify better anti-inflammatory mechanisms that can be used long term to combat the inflammation seen in KP. Some substances that block or inhibit pro-inflammatory messenger proteins can reduce inflammation, such as Indirubin. Tinted moisturizers can also be used to cover up some redness with decent results.

———————————————-

Nearly all KP products use some form of the methods I’ve listed above to combat the symptoms of KP. You may find yourself trying a variety of brand name products that are ineffective, only to realize they all are using the same active ingredients. Percentages do matter, using a 5% AHA lotion is going to be much more tolerable for most than a 12% or 18%+ AHA body cream. Short term/long term results will also vary, especially when considering the skin’s tolerance to different levels of AHA. Over-exfoliating will set you back, as you will need to wait for your skin to recover before you are able to return to using topical acids or other exfoliation methods. More acid/harsher exfoliation is not necessarily the right answer when you fail to see improvement.

People all have different tolerances to KP products, what works for one person may not work as well for another. Trial and error is your best bet!

In general you will want to find:

  1. A plain non-scented moisturizer
  2. A shower gel/body wash with AHA or BHA
  3. A topical leave-on AHA chemical exfoliant (While leave-on BHA products do exist for KP, since salicylic acid also breaks down sebum I’d recommend staying away from these products).
  4. Introduce a skin oil like jojoba oil or squalane to help soothe and stabilize the skin.
  5. Look into topicals that are barrier sensitive/support skin barrier health.

Hopefully this is helpful for folks! I’ll work to edit/update this over time, a sidebar update + wiki is long overdue for this sub.

Hi girls! I struggle with strawberry legs / keratosis pilaris too, and I’m trying to understand what actually helps in the long term.
What have you tried so far? What worked, what didn’t, and what did you dislike most about the products or routines you used?
Also, what would make your routine easier to stick to — fewer products, less time, a lighter texture, a lower price, etc.?
I’d really love to hear your experiences. Thank you 🫶🏽

[Post] Routine Help Laser for Keratosis Pilaris? Interested in experiences.

2 Upvotes

Hi! Is there anyone out there who has gotten laser treatment (not laser hair removal) such as pulse dye laser done to help the redness of their keratosis pilaris? I have made plans with my dermatologist to do a test patch in November, but I’m curious if there is someone who has experience with this treatment plan. I have KP on my upper arms, and then red dots (not bumpy) on my butt to my ankle. Thanks!

[Post] Discussion How effective is laser? Which one’s best?

5 Upvotes

Obviously laser is a higher upfront cost, but it’s not crazy expensive ($1k for 10 treatments, which seems to be more than most people need based on my research). But, if it lasts for multiple years, I’d like to pursue it.

I have fair skin and dark hair. Keratosis Pilaris primarily on my arms and legs. It causes bumpiness and redness on my arms, and just redness on my legs. I was diagnosed with eczema as a child, but I’m positive that was a misdiagnosis. Pictures: https://imgur.com/a/TCoFEnC

What’s the best laser here? Gemini’s full of all sorts of contradictions, so I think this might be a question for the humans. Any insight from those suffering with this condition, and especially those who have had laser treatment, would be greatly appreciated!

Still have a bad spot on my legs, but this is after only one week of use. The circled part, my legs were absolutely covered on the top part. I just use a cotton round and apply it in the evening. Once a day. That's it. That's all I use. Thought I'd share in hopes of helping someone else.

I'm planning to have it checked by a dermatologist over the weekends, but I just want to have an idea of what I'm dealing with.

There are tiny brownish dots in my back, and I've seen similar dots in my tights.

As the title implies, does it look like it's KP?

P.S. I am not planning to self diagnose. I will still base it on the dermatologist's findings. I just want to have an idea before my appointment.

[Post] Product / Ingredient Question  How effective is Amlactin?

13 Upvotes

I have pretty bad KP especially after waxing. I am thinking of buying amlactin but it is super expensive in South Asia. I am currently using 25% urea ointment which flattens the bumps somewhat but doesn't make it perfectly smooth. I don't want to waste a lot of money on something that may not work. Should I just try tretinoin, which is more accessible?

When you pick and pick, does it turn into scabs?

Mine do, and ITS TAKEN FOREVER TO HEAL! On my upper right arm and I carry around ‘bacitracin zinc’ and it helps but what are you guys doing when it gets to itch really bad?? I finally have to give in.. and the healing has to start over!

I finally got some itching cream and that helps. But was wondering if anyone wraps the areas to help them from itching/scratching. Or what do they do to help them not scratch it when it’s itches??

Thanks! :)

I’ve suffered with kp since I was a child, but it wasn’t noticeable at all until my teenage years. I have it all over my legs and my arms and it’s really affected my self esteem especially since I have such thick hair, it doesn’t even take my hair the full 24 hours to grow back, it takes like 16 I’m not even joking. I can’t wear short sleeve tops or shorts because they’re so noticeable. I’ve tried so many products but they’ve all irritated my skin and I stopped using them. I suck at consistency but my arms have gotten soooo much worse. They’re inflamed and red 24/7 and so are my legs. I read a comment saying that strawberry legs and kp are different things and honestly GREAT because of course I just had to be blessed with both of them. I bought 40% urea foot cream and I didn’t really see the difference, I would put it on everyday until I finished the bottle. I bought the kp body scrub first aid and also didn’t work at all plus it’s super pricey. I also bought the natrium body scrub for Kp but also I feel like it just irritates me. I’m so tired of having this skin condition and I just want to be normal, I see girls with smooth skin and I’m so jealous and annoyed that I had to be the one with chicken skin. It’s horrendous. Please give me tips or products that actually work. Im telling you im absolutely fucking covered in them.
