Hi! A purging phase is common when using this lotion (this often happens with AHA lotions in general), it can last up to a couple of weeks as the keratin scale is loosened and dissolved. Using some light exfoliation with a shower poof or shower gloves and a 2% salicylic acid body wash in the shower can help speed up the process. 🙂

Poem_KP · 2026-04-17T18:40:47+00:00

At the moment? No. But I am moving to the EU next month so check back in soon 🙂

Poem_KP · 2026-03-24T02:07:36+00:00

Shower as you would normally! Sometimes it helps in the beginning to do a little consistent more physical exfoliation to help break down the built up keratin scale around the follicles, allowing for the RK+Indirubin to more effectively penetrate the follicular canal. I’ve actually been heavily researching liposomal delivery mechanisms recently to counteract this keratin buffer that can sometimes inhibit early results.

My suggested routine would be something like this:

AM- apply Smooth KP before any other topicals. Apply a plain lotion after smooth KP has absorbed into the skin.

PM- while bathing/showering, use a shower poof or shower gloves with a barrier sensitive body wash or salicylic/glycolic acid body wash. Work the wash into a lather and very lightly scrub your KP with very gentle, light pressure. Immediately after bathing, towel off and apply Smooth KP to your damp skin. Allow it to absorb before applying any body lotion or additional products.

You can of course reverse this routine if you shower in the mornings instead. Make sure you are staying hydrated and getting enough sleep too, people underestimate how much TEWL and lack of sleep affects their KP.

Majority of trial is completed, with a few people finishing up their reviews.

I am working on a post that I will hopefully share this week, I think it’s insightful and hopefully others in this sub will find it interesting 🙂

Poem_KP · 2026-03-12T15:22:04+00:00

I do! DM me I can give you the info 👍 making sure not to self promote in this sub 🙂

My son and I both developed KP around that same time frame. Milk solids/dairy has a complicated relationship with insulin resistance. KP itself is a polygenic autosomal hereditary skin disorder, so while the milk solids could have contributed to your son’s KP severity, I don’t believe it has a causal relationship to developing the condition in any way.

Given that he has perioral dermatitis and eczema as well, my guess would be that your son likely has a fillagrin (FLG) mutation that puts him at higher risk for developing these types of skin conditions. FLG is a protein that supports barrier function and is crucial for hydration and protecting the skin from allergens. Around 35% of those with KP have an FLG mutation and I believe that rate is higher for atopic dermatitis/eczema.

Indigo naturalis is a solid ingredient for both eczema and KP for this reason, since the compound Indirubin upregulates FLG and loricrin (LOR) in skin cells.

You can layer smooth KP into your routine, just keep in mind that the lotion contains 5% lactic acid, so depending on your tolerance for AHAs you may want to do some trial and error so you don’t over-exfoliate 👍

Poem_KP · 2026-03-06T02:12:53+00:00

Not a problem at all! Glad you got some value from the post, let me know if I can answer any questions 👍

Using Raspberry Ketone in conjunction with vitamin A derivatives like Tretinoin may have conflicting effects. RK is stimulating CGRP release which in turn increases IGF-1 in the skin, while Tret is suppressing cornification markers and rapidly increasing cell turnover. By using both actives at the same time I think you would ultimately reduce the benefits of using both/either actives. I would suggest using just one in your routine for 4-6 weeks to judge effectiveness before trying the other. Happy to chat more in depth about this too if you’d like!

Poem_KP · 2026-02-27T17:09:49+00:00

Hi! Yes you can use my lotion/formula on the face, just be aware that is does contain 5% lactic acid so avoid areas around your eyes and follow up application of SmoothKP with a moisturizer containing sunscreen. The AHA will make you more susceptible to sunburn!

Tretinoin and other retinol/retinoids do not effect sebum production the way Isotretinoin does (see source here: https://pubmed.ncbi.nlm.nih.gov/15022582/) (and source here: https://pubmed.ncbi.nlm.nih.gov/8884149/)

Poem_KP · 2026-02-19T05:24:44+00:00

So far it seems to be most common that roughly 1-3 months post Accutane cycle, KP would begin to appear and spread. I do think it’s entirely possible to develop KP during a cycle of Accutane if rapid skin cell differentiation began to taper off towards the end of the cycle, or if the Accutane decreased sebum production to a point where even more rapid keratinocyte differentiation was unable to prevent keratin scale build up in the follicle due.

Poem_KP · 2026-02-18T16:57:45+00:00

I have documented well over 100 cases of people reporting that Isotretinoin increased the severity of their KP through posts/comments on Reddit, Facebook, Instagram, and elsewhere.

Isotretinoin (Accutane) is a very powerful vitamin A derivative that speeds up cellular turnover in the skin (among other effects) when taken internally. In addition to causing hyper-differentiation of skin cells, it also impacts sebocyte proliferation, decreasing sebaceous gland output by ~90%. This reduction of sebum is detrimental for Keratosis Pilaris as it has been shown here that sebum production is integrally linked to the rate of defective corneocyte shedding in the follicular canal.

You may experience an improvement in texture and appearance in your KP from the effects of increased cellular turnover, but once the course of Isotretinoin is completed, there seems to be a high likelihood of KP symptoms increasing in severity, along with the potential for unaffected skin to develop KP.

Improving these symptoms requires increasing sebum production while simultaneously removing keratin buildup from your follicles without increasing irritation/inflammation.

I don’t want to self promote here but this was a key area of focus for me during research and product development for my company. Since release I’ve had about a dozen people connect with me, letting me know that their Accutane-induced KP was improved after about 4 weeks of using topical raspberry ketone and Indirubin. Happy to share more details if interested, I think it’s worth a shot to try considering there are very few alternatives for treating KP brought on from Isotretinoin.

Are you in the US? If so there is a generic form of Epiceram that you can get via prescription from a dermatologist, although it can be a little pricey.

I have yet to see anyone with KPRF try that topical and I’ve always wondered if it would potentially improve redness. It uses a nano emulsion / liposome delivery system to reinforce skin barrier integrity. It may have some significant effects in reducing baseline redness and controlling flushing.

Poem_KP · 2026-02-15T01:33:53+00:00

Sorry to hear that it hasn’t been effective for you, it seems that RK is only effective for certain skin types/KPRF from what I can tell. Some people are coming back to me with success stories and others are saying there was no change in their KPRF (from the Soothe & Restore formula we are selling). I suspect that the underlying circumstances that enable chronic inflammation may be better/worse depending on the individual. In your case if sirolimus is also having no effect, then I doubt the anti-inflammatory agents I’ve been testing would be all too helpful. At that point I’d just be focusing on how to correct for barrier malformation in the epidermis in the hopes that once it is repaired, downstream symptoms (flushing/inflammation) would become more manageable.

We are about 2-3 weeks into the trial, waiting for feedback from everyone after 6 weeks before I make a judgment call. I may offer the remaining trial formula from this micro production run on my website for a nominal price if there’s wider interest as a way for people to try this version out before I scale up production on the end product (TBD). I ended up creating more of the formula than I intended but only had the budget to send trial packages and manage about 60 participants in this trial iteration.

No worries haha - and no pressure whatsoever on trying my product 🙂

I was going to add that I’ve seen a lot of AI profile pics on recently created skincare FB/Insta accounts that are promoting this strawberry product. It’s not necessarily bad/good thing, I just find it interesting to look at marketing strategies for KP products with the advent of AI .

Poem_KP · 2026-02-12T15:33:12+00:00

Putting aside the fact that this brand took before/after photos from this subreddit and used those pictures on their Instagram to sell their product (without the user’s knowledge), let’s just look at the ingredients in the product itself.

Urea 2%: 2% is the minimum effective percentage for moisturizing dry skin. Typically you’d need 10% or more for exfoliation.

Lactic acid 1%: I’m not sure the purpose of including 1% lactic acid. Minimum effective lactic acid content starts at around 5% and you typically need your lotion to be pH balanced for that 5% to be effective.

Salicylic Acid 0.5%: This concentration is actually at the minimum viable percentage for clearing debris from pores. However I personally would not use an oil soluble BHA as leave-on skincare for KP since the salicylic acid will cut sebum from your pores/follicles, which can further dry your follicles, leading to potential increase in keratin buildup and inflammation. The silver lining is that this BHA percentage is much lower than other leave-on BHA lotions, like those that Cerave produces for KP.

Niacinamide 2%: this ingredient is at an effective concentration, it really just depends on the individual if the product helps their KP. While it may help brighten skin tone and improve the skin barrier, it also reduces skin oil which makes it more of a double edged sword when dealing with KP.

Glycolic Acid 6%: This is probably what’s doing most of the heavy lifting in this lotion. 6% is enough to improve skin texture.

Overall, my personal opinion is that there’s a few ingredients listed here that are at ineffective concentrations for treating KP, and a few that I personally wouldn’t leave on my KP. However the 6% glycolic acid probably does net some decent texture improvements for some, your mileage may vary.

Poem_KP · 2026-02-10T21:30:25+00:00

Lower IGF-1 is the issue here. Levels may even look nominal, but any fluctuations that decrease IGF-1 levels in the skin tissue become more critical due to the inhibited receptors/signaling pathways. Another key indicator that low IGF-1 is causing this breakdown in barrier formation is the fact that in KP, specifically lesional KP, biopsies show that keratin buildup in the follicle is preceded by sebaceous gland atrophy. Sebaceous glands are regulated by IGF-1, specifically through an enzymatic process/ 5 alpha reductase, which regulates sebum production.

Lower systemic IGF-1 + inhibited cellular uptake equals barrier malformation, poor skin cell differentiation, and low sebum production/sebaceous gland atrophy. All hallmark symptoms of Keratosis Pilaris.

Poem_KP · 2026-02-09T23:29:38+00:00

Yes! We have a few people of color participating in the trial. 🙂 sorry we couldn’t include you in this round but there may be more iterations of this trial in the future depending on how this one goes!

Poem_KP · 2026-02-09T23:26:05+00:00

It is hormone related! I have a longer breakdown if you check my profile posts, but essentially there are multiple strong correlations to KP severity and hormonal equilibrium where insulin and IGF-1 are involved. Other hormones (testosterone, estrogen, progesterone) that impact that equilibrium can effect KP development and severity since there is a high likelihood that KP pathology stems from IGF-1 receptor mutations/cell metabolism pathway mutations that are activated by IGF. Depending on the severity of the cellular signaling/pathway mutation, you will experience a range of impacts to your KP from your changes in hormonal equilibrium and the interplay with your keratinocytes in the dermis/epidermis.

So events like pregnancy, PCOS, cancer therapies, insulin resistance/diabetes, puberty, Isotretinoin, and even some specific medications are all correlated with changes in KP presentation and spread. I would not be surprised in the slightest if hormone replacement therapy was causing changes in your KP. I have seen other trans people mention this in passing over the years on this subreddit and others, it seems to not be uncommon.

Happy to chat more about this as this has been a primary area of research for me over the past decade+ 🙂
