Red Light Therapy for Penis Size: Benefits, Risks, and What Works

Added: 2026-05-12

[00:00:00]Hey guys, it's Sink here. So today I have to bring you a re-evaluation of basically red light therapy, near infrared therapy. We need to talk about this because there's actually quite a bit of interesting data. You may have seen my part one video where I talk about red light therapy and the potential implications, especially when it comes to enlargement. But I actually want to double back around and do a deeper dive because there's some very important clinical implications when it comes to discoloration whether it be through post-inflammatory hyperpigmentation or hemoceterin staining. There's actually new data regarding erectile function, smooth muscle cells, lymphatic drainage, lysolidase and fibrosis. There's a lot of things that we need to discuss today.

[00:00:42]So let's break it down. Before we go into that, guys, if you just take a second, cost you nothing to leave a thumbs up. And of course, if you're interested, please become a subscriber if you like what I do. And guys, I'm also going to be talking about red light therapy for hair loss restoration as that's something I'm currently involved in. And so, if you're interested in hearing me talk about that, make sure you subscribe to my other channel and I'll leave the link in the description below for that. So, guys, the first thing I want to talk about is this paper here looking at erectile dysfunction.

[00:01:08]Now, I will give you this is a paper looking at rat peeps. Okay? So, if you think your job sucks, at least you're not measuring erectile function in rats.

[00:01:16]But like look, look at how they did this study. I mean, this is the wildest stuff I've seen. Like that these have these rats spread eagle. They're shining that near infrared light on it. That's just wild to me. I don't know. Just just that idea. But there's some important things that came from this paper. You have improvement in smooth muscle cell distribution. You have reduced collagen deposition. You have increased nitric oxide synthes. And there was the promotion of angioenesis. And so all of those things are actually very important when it comes to potentially PE in general or penile enlargement, but also just when it comes to penile health.

[00:01:48]This measurably increases those. Now, there's an important caveat that you need to keep in mind through all of this that wavelength matters. And also the energy or the fluence level matters a lot. And so for this study specifically, they used 808 nanometer wavelength lasers or laser light therapy. And so there is a difference in distribution as far as how deeply things penetrate and what you can use them for. Double entandra there. I'm going to cover that more in just a second, but just but keep that in mind. So that's the first data we're going to cover. And that basically is saying that there's pretty clear evidence that in rats that have basically a decrease in erectile function, this could potentially be helpful. Now, is this to say that if you have a normal healthy male with good erectile function that is going to help them? Like no, you cannot extrapolate that. However, it is still interesting data, especially for guys recovering from any sort of trauma or injury or if you are happen to be an older human male, you might be suffering from some mild erectile issues, this could potentially be beneficial. Now, next is discoloration. Guys, if you haven't seen my whole video on discoloration, I took you through a very deep dive with that.

[00:02:52]I highly recommend you check that out as far as the different types of discoloration. But when it comes to red light therapy, what they're seeing is that there's actually pretty good data for bruises and hematomas. Okay. Now how that is applicable once again guys I'm extrapolating here but when we're looking at the major cause of discoloration it's hemoceterin staining or basically blood cells leaking out into the epidermis and causing staining there and so if you can have resolution of bruising with this then it makes sense that it could potentially help with the hemocenter staining. Now is there evidence for this? Yes guys look at this before and after picture. Okay.

[00:03:26]Now, this is about a two week differential, but there's actually very clear data that with bruising specifically, you can have a significant improvement. Now, I found this quote particularly interesting is that the near infr infrared uh light can actually improve the rates of hemoceterine absorption by 3.5 times. That is significant and that is potential clinically meaningful when it comes to hemocetin staining. Now, how does it do that? Well guys, through several different processes and I'll put it on the screen here, but you can see there's nitric oxide release, there's a faggocytosis boost, there's vascular repair, and there's anti-adema, which you know, we're going to circle her back around to. So, it actually makes sense.

[00:04:06]There is clinical evidence, and there is a physiologic explanation for why it could be beneficial for all of these things. Now, once again, wavelength matters. Okay, so for this, they're saying about 830 to 850 nanome is the ideal wavelength. Now, personally, I think there's also evidence of this potentially being helpful for post-inflammatory hyperpigmentation, the other cause of discoloration, actually stimulation of those melanocytes. And for many of these reasons above that I just showed you on that chart, it can potentially help. There's also, as we'll get to, evidence of decreased fibrosis and just inflammatory markers in general. And so, if you have decreased inflammation, you're going to have decreased post-inflammatory hyperpigmentation. I'm extrapolating, guys. I don't have a paper saying yes, it decreases post-inflammatory hyperpigmentation.

[00:04:50]>> Don't do the voice.

[00:04:51]>> Now, guys, similarly, so we just looked at hematoma data. Let's briefly look at bruising data. And so, guys, here's a pretty impressive before and after. Now, this is saying, you know, 30 minutes after one of these name brand treatments. However, you can clearly see that the lighting is different, the angle is different, and so I I don't like how that's manipulative, but I do think you can see a mild improvement.

[00:05:10]Now, that just gives further evidence of this potentially being helpful with hemocenter staining. But I also think that this is important for patikia. And so, if you have those little red dots, guys, if you haven't seen my video on pikia, check it out. But if you have those little red dots every single time you pump and you're trying to get rid of them, using red light therapy would potentially help with that. And if I really really kind of twist the data to fit my needs, I think you could also say there's evidence that it can help actually prevent pitikia as well, but I don't have great data for that. And that's mostly through improving basically the vascular channels. Now guys, let's get into the wavelength matters discussion because in this the size size definitely matters, okay? Or the wavelength size at least. And so when we're talking about penetration, so you're just looking for something for your skin, okay? Then as you can see here, guys, you can look for something somewhere around like 600 nanometers. It gets to the skin. It's pretty it's pretty superficial. Okay? Now, when you start getting into like almost the 700s, that's when you can start to see actually penetration into the epidermis and the dermis, you can see boost in collagen and sometimes improvement in skin tone. Now, when you start to get to like the 810 to 830s, like on the rat study, they used that. On the hematoma study, they also used around the 800s.

[00:06:23]That's when you can start to penetrate a little bit deeper. And I do think around 800, you could potentially see activity in the tuna, which could be a good and a bad thing, guys. So, so stick around.

[00:06:33]Don't don't jump. You guys need to listen to this whole video. Now, guys, one of the reasons I said hold your horses is because of the impact on collagen. Okay, you can debate me on the collagen thing. I I get it, guys. I I just think that excessive collagen deposition is not a good thing and it is not something that we can strive for.

[00:06:49]And I think that that that's not a hot take. I don't think that's a spicy take.

[00:06:53]Now, if you look at collagen impact, you can see here like in this paper here that using the red light actually led to a almost 50% increase in average collagen density. Something that makes my my little nervous meter start start ticking up a little bit. Now, what makes it nerves start ticking up a little bit more is the fact that you have increased fibroblast activation as well. The fibroblasts are what are the important cells that actually secrete collagen, secrete lysolidase. Okay, I'm not going to go through all that in this video.

[00:07:21]And yes, guys, there is evidence of increased fibroblast activity when you stimulate it with red light. But once again, guys, this is where wavelength matters because I think if you're just using something superficial like 600 to 700 is not getting into the tunica and I don't think you're going to have much stimulation of collagen within your tunica. However, if you try to reverse discoloration and you're using something that has like 800 nanometer wavelength, you know, then we start talking about, hey, maybe you are actually penetrating deep enough where you could be stimulating collagen and lysol oxidase.

[00:07:51]But hold up, pink, this is just looking at red light therapy for collagen. Why are you extrapolating lysol oxidase?

[00:07:58]Well, let's get into it. So, for those that don't know, there was a rat study that basically showed that if you can block lysol oxidase, that alone increases the size of a rat's penis by almost 10%. Okay? Okay. And when you combine it with something like pumping, you actually can increase the size of a rat penis by almost 20%. Okay. So lysol oxidase is the key. It's the glue that holds the collagen fibers together. And when we're trying to do enlargement, we want that glue to be as liquid as possible so the collagen fibers can expand so your penis can actually grow.

[00:08:25]Now guys, here's where nuance comes in as well. Okay? So when we're talking about red light therapy, it can both either increase or decrease lysol oxidase activity. And it depends on basically the fluence of the energy or basically how much energy you're depositing over time to that area. So why this matters is because if you're using a red light therapy, it can actually help to organize the lysol oxidase and organize collagen fibers.

[00:08:52]And so if you have something that's called a kloid guys or like a hypertrophic scar where you have really big scarring but what you can see is that it actually can reduce some of these disorganized collagen fibers and excessive like lysol oxidase activity and so that could be a good thing in this case. Now how does it actually do that? Well guys, there's evidence of this YAP TED Tea locks signaling. And so we have evidence that high fluence red light therapy can actually limit that activity and therefore limit the ability of locks to basically do its thing. But once again, that's with the high fluence or that high energy deposition pathway.

[00:09:32]And so you have to be very particular with how you're using it because if you use that high fluence, yes, you can actually inhibit locks and that could potentially do good things as far as growth. But the other type with just regular kind of your standard lowfluence red light therapy, that is something that if you have Peryon's disease, for example, or you're prone to it where it's a disregulated collagen deposition could actually be a good thing.

[00:09:57]Theoretical guys, talk to your doctor.

[00:09:59]Clowning a mask here. Okay. Now guys, similarly with fibrosis, a lot of you guys are hopefully worried about penile fibrosis and hopefully care about the overall health and well-being of your penis and how it's going to function long term, not just where you are right now. But guys, there's evidence that once again, high fluence red light therapy actually can decrease especially the myofibrolast. Now, if you guys saw my live stream with Carl Wickman, he talks about this, but those are the really bad actors, okay? That's what you definitely want to avoid at all costs.

[00:10:28]But once again, there's also cytoine modulation. So things like TGF beta 1 that can be decreased with red light therapy and you can actually see increases in MMPPS or matrix metallop proteinase is things that are going to break down the collagen bonds and can be a good thing when it comes to growth.

[00:10:43]I'm just going to put on the screen here for time sake so you can read the different articles and different examples of actually how red light therapy can decrease different rates of fibrosis. So I think it could be a good thing with penal health in that regard.

[00:10:54]So finally we're going to talk about lymphatic impact. Okay. Now guys, there's no evidence of looking at the fagio scerosis in the pee pee. However, there is a lot of evidence in people that suffer from lymphatic difficulties and things like lympadeema. And so look at this first thing here. Okay, there's a meta analysis found that 93% of patients with breast cancer related. So guys, look at this meta analysis here.

[00:11:14]2026 meta analysis showed that 93% of patients with breast cancer related lympadeema experienced up to a 22% reduction in limb volume, okay, after 10 to 12 sessions of red light therapy. And there's even evidence like this paper here that basically showed that two sessions of red light uh therapy improves tissue softness and reduced swelling in people with lympadeema and it was a prolonged benefit. And guys, it does this through several pathways including lympangioenesis, increased motility, reduction of fibrosis and immune modulation. So there's legitimate evidence for this. I do think it matters once again the wavelength that we use because most of the lymphatics in the penis are pretty superficial and just located basically within the dermis and epidermis. I don't really think you need to go above 700 for this specifically.

[00:12:01]Okay? I don't think you need to penetrate deep down into the tuna cuff for that. If you are having issues with chronic swelling or edema in your penis, especially if it seems to be getting worse, this is something you might want to consider. or if you're having issues with chronic lymphosils or lymphio sclerosis. Once again, this is another thing that could potentially help mitigate that problem. So guys, in summary, I think that it can be good for things like pikia, hemoceterin staining, lymphatic issues, possibly even mild erection quality benefits if you are older or and have a damaged penis or if you have some sort of increased risk or you have peronis disease and still want to do PE. However, if you're using low fluence, red light therapy, I think it can actually stimulate collagen and stimulate locks, which could be long-term detrimental to your growth.

[00:12:49]So, you need to make sure if you're using it, you know what fluence it is.

[00:12:52]Now, what are my thoughts? Am I going to start doing this? Well, I actually have a little red light laser therapy that I bought from actually my last video. Am I been using it? No, guys. I I haven't.

[00:13:02]I'll be honest, okay? If I have problem with discoloration, I know how to do discoloration. I use lymphatic massages and whatnot. if I have any lymphatic issues. And so I just don't feel like I have time to incorporate this into my life. Now, that being said, I have a very busy life. You might have a little bit more time in your hands. And if you're interested in that, I will try to leave the link in the description of a solid product that I recommend that I think has the wavelengths of what you're looking for. But my overall verdict is it's very interesting. It's very hypothetical data. It could help. If you have a big issue and you've been trying other things and it hasn't helped, maybe it's worth considering. And guys, I clearly do a deep dive. I've been studying and researching this for the past 5 years on top of all of my medical knowledge from actually being a yes, a real medical doctor. And so, if you're interested on how to get bigger using real medical techniques and real published data, please consider my course. Thousands of guys have done it and thousands of guys have gained with it. Now, if you don't believe me, check out my he trial below. The guys used my techniques and my methods and on average grew over half an inch in length and a/4 inch in girth with images you can see guys unlike any of the other published data. There's before and after you can see and you can see for yourself if you believe it. That's going to do it for this one guys. Just remember you are enough just as you are. I'll catch you in the next one guys. Peace and love.
