Dermatologist Q&A | Thin Skin, Epiduo, Weightlifting & More

Added: 2026-05-12

[00:00:00]Hey guys, happy Sunday. I hope you are having a fantastic weekend. We are picking up. We're picking up where we last left off with these questions that you guys asked. You dropped some good ones. Can I use only the road glazing milk without any other moisturizer? In other words, can I use it as an everyday moisturizer? Yes, you absolutely can. I love that product. Personally, I find it a very hydrating, moisturizing, lightweight, fluid. I mean, you don't necessarily need to use additional moisturizer. Of course, everyone's skin needs will vary. Some people will benefit from additional moisturizer. Can it can easily be used as a standalone moisturizer. This person writes, "I'm worried about using salicylic acid on my scalp now because I ended up getting scalp micropigmentation. I don't have access to a cosmetic dermatologist."

[00:00:47]Okay. So, I think this person is concerned because I mentioned, you know, salicylic acid is really good for getting down into the pore and exfoliating it and it's approved for use on the scalp as an over-the-counter anti-dandruff ingredient. This comes from last weekend where people were asking about putting glycolic acid on their head. And I was like, I mean, you salicylic acid, you got a ton of sebum up there, ton of oil glands, go with what can actually get on in there. Now this person is concerned it sounds like perhaps if I'm reading this correctly that you know the exfoliating will hasten or lighten your micropigmentation. So scalp micropigmentation is placement of pigments in the superficial dermis to basically make it look you know to mask cosmetic tattooing in a sense to mask areas of thinning hair and um people can be very satisfied with this. The nice thing about it as a side note is that some people have to undergo scalp reconstruction. they get a scar and scar I've mentioned this before hair does not grow from a scar I mean hair once a scar forms there's no hair coming out of that and scars do not also really pigment evenly so you can tattoo um with the micro pigment over over the scar it's the fact that the ink is down in the superficial dermis exfoliating the skin is not going to lighten that pigments that are placed in the dermis whether it be superficially or deep they fade over time due to exposure to light. Sunlight can lighten them and also um as that pigment drops down and drains into the neighboring lymph node, it can alter the color. Now, that being said, a lot of it will depend on the skill level of the person who did it. Um because if somebody's real novice, doesn't quite know what they're doing, they might end up placing a lot of the pigment up actually in the epidermis, in which case it will lighten a lot faster with salicylic acid, but it'll lighten regardless because the epidermis is, you know, turning over on its own and so that pigment would get cleared out eventually. But anything down in the papillary dermis where it should be that's meant to last to provide lasting pigmentation is not going to be lightened by using salicylic acid. My mom has thin skin and is starting to get skin tears. Will amlactin help with thin skin on the elderly? It can. So, um 12% and higher ammonium lactate has actually been shown to reverse dermal atrophy after about 3 months of consistent use.

[00:03:09]Um dermal atrophy specifically related to topical steroid use but also may be helpful for dermatoperosis which is age related thinning especially in sun exposed areas. um namely the backs of the hands which is not just a cosmetic issue like you pointed out skin tearing becomes more likely persistent stubborn bruising the skin doesn't heal as well vulnerable to infections discomfort yeah um this can certainly help for sure also um filler can also help to a certain extent but the placement there is tricky it is an area that is more inclined to get the little superficial nodules which you know cosmetically speaking isn't great it has a bio stimulatory effect So it helps your body to produce more collagen locally and therefore can help quite a bit actually. So it's not just a cosmetic thing here, right? It's it's functional as well. Can Epiduo or combination of Epiduo and Caravee moisturizing cream cause small scars on the skin without any visible acne?

[00:04:07]Epiduo stop my acne but scars keep forming and my skin looks less smooth.

[00:04:12]Uh no. So Epiduo is adapylene and benzol peroxide and those retinoid and benzole peroxide. Not only do they not actively cause scarring, but they will prevent and decrease the likelihood of acne scarring both by controlling the acne and then the adapylene helps with dermal remodeling to help with ultimate healing to diminish the likelihood of scarring.

[00:04:34]Plus, it's anti-inflammatory. So, no, these this combination doesn't cause scarring. Now, what a lot of people end up confusing scars with what they actually have is either post-inflammatory hyperpigmentation or persistent aythemma. Especially if you have a deeper skin tone, post-inflammatory aythemma can really fool the eye because it can look kind of like hyperpigmentation, but also just sort of almost like a scar, right? And honestly, even even really well-trained dermatologists sometimes have difficulty distinguishing like the aiththemma from the true melanin pigment and they find that as they're treating surface things and other things become clearer as to what's going on. And so what might happen is say for example you've gotten excessively irritated by these well you could get post-inflammatory hyperpigmentation due to the irritation and maybe you're thinking that that is a scar but no it doesn't it doesn't actively scar the skin I have pressure herdicaria and I get a r a rash from elastic could that also be a cause versus an allergy okay so this person was asking about the elastic waistband again because we brought it up last weekend because um basically you can become allergic to elastic in like your underwear waistband or waistband of pants. Elastic waistbands specifically if they've been bleached, they release rubber accelerators from the elastic.

[00:05:54]And some people are allergic to those and they get these horrible rashes underneath the elastic and they have to, you know, get new underwear or whatever cuz it tends to become a problem once you've washed and especially ble namely bleach the elastic over time. It releases more of that allergen. Well, um there are actually a couple of other things that can go on with your underwear elastic. So, this person mentioned um pressure herdicaria. So, pressure herdicaria, yeah, it can happen to the underwear elastic, but it's not an allergic contact dermatitis.

[00:06:25]Eurtdicaria, as a side note, is just the medical term for hives. You can get hives related to pressure on the skin, and there are actually two variants.

[00:06:32]there is um an immediate pressure ordicaria where like pretty shortly after pressure on the skin the hives will appear waistbands are common crossing your legs for example another thing that can bring it out um also stroking the skin dermatographism is an immediate pressure urtdicaria delayed pressure urtdicaria is going to present with hives about 4 to 8 hours after after the pressure has been there but in the case of allergy to the rubber accelerators in in the underwear elastic it's going to be a delayed type hypers sensitivity will appear a lot more quickly as opposed to allergic contact dermatitis the rash usually manifests within earliest a day 2 days right it's pretty typical now there's another one though called contact urtdicaria contact urtdicaria it's a variant of of hives uh contact urtdicaria and in that case typically you get it's an immediate hypersensitivity ity reaction. So you put the wa the waistband on immediately you get hives. It has nothing to do with pressure. In this case it has something to do with what's in the waistband. It's an immediate hypersensitivity reaction to something in the waistband. And what would be most likely would be latex. So latex is a common reason for contact herdicaria hives on contact with latex.

[00:07:54]That wouldn't be a delay type hypersensitivity aka allergic contact dermatitis to the rubber accelerator. it wouldn't be a um pressure because it's not the pressure like if you press on other body sites test do a pressure test it's not going to elicit hives in that case um it's going to be contact though of the skin um immediately will result in hives if you contact the skin with in this case likely latex um for contact herdicaria which can be found in those waistbands can you speak about the effects of weightlifting on the skin weightlifting I mean kind of depending on the body site the location, a variety of other things that stretch force can cause stretch marks. That's something that a a lot of bodybuilders actually develop. Um, so that's definitely something that can happen. Just like with weight gain, you can get stretch marks. You can get stretch marks with putting on a lot of muscle, especially over a quick period of time. Some people are just more inclined to developing stretch marks than others. It's like you either are or you're not. You know, there's not really anything that aggressively prevents them. It's hard to predict who's going to make them and who's not. But I will say um weightlifting in general resistance training um it doesn't directly anti-age your skin but it indirectly definitely has anti-aging benefits. First of all like if you think about it just from a crepey skin, saggy skin perspective.

[00:09:13]It's volume. It's volume from muscle that's going to help offset volume loss that happens with age. Um you know it's going to be make volume loss with age less dramatic, right? You're you're maintaining it. Muscle is a a tissue though that really does a lot for your overall health as far as your metabolic health and glycemic control. It can help secondarily with skin aging as a result.

[00:09:39]Better glycemic control, blood sugar control. That lends itself to less glycation in the skin, less prominent aging. Also you have better blood flow, better circulation when you are doing you know that could come from cardiovascular exercise as well and to a certain extent resistance training also can stimulate the fiberblast. Yeah I mean it does it does have benefits. Now that being said you know there's you you'll point to various people who seem to have aged very quickly in spaces where there is you know a heavy focus on weightlifting. And why might that be?

[00:10:15]Well, in some weightlifting communities, there is uh the tremendous pressure, namely in those who do competitions to take various performance-enhancing medications, drugs, substances that um are not healthy for you and do, you know, contribute to aging.

[00:10:32]Performance-enhancing drugs can definitely have a very pro-aging effect for sure. Like some bodybuilders, for example, abuse insulin and growth hormone, which Yeah. I mean, that is just not that's that's that's so dangerous. that's so dangerous. Like I I wish things were different for that sport. Like it's kind of just accepted in that sport that that's how it is. And I feel like it's kind of absurd that in order to like really compete, I mean, yeah, they have natural bodybuilding, but in order to like be in some of the big things, it's like they're all expected more or less to abuse stuff that's really bad for your health. want to paint the whole industry in, you know, a negative light, but it's like I think if you're in that industry, you know exactly what I'm talking about.

[00:11:15]Like there's just a lot of people who go to, you know, really dangerous places with it. And I think that that should just not be acceptable. And it's it's wild that it's just like, yeah, that's how it is. if you want to do this, that's what you're going to because you look at, you know, back in the earlier days of bodybuilding when that was not prevalent and you compare and contrast the physiques of people from back then to now. It's like, why can't we go back to that? It looked a lot more natural, attainable, and it wasn't associated with all this stuff. Like, why can't we keep that as a standard? I don't know.

[00:11:48]We have to be pushing things to extreme.

[00:11:50]And in the case of bodybuilding, it's just like really, really dangerous. I mean, spending the amount of time, this is a scary thing. Okay. So, like that's like a niche, right? Competing and a certain type of thing where there's like a specific goal. But you now you have on Tik Tok especially these large communities, mostly of young men, but also a lot of young women as well, who have zero interest, zero interest in actually competing in the sport, right?

[00:12:14]They're not looking to go to the Olympia or whatever. They're not looking to to compete. They're not really in love with bodybuilding, the sport, per se. I mean, they like it. It's more of a hobby that from a very young age are doing these aggressive performance-enhancing drugs that have all kinds of serious side effects like Yeah. And they they check their own blood work. Um and you know they take all these supplements to offset these negative. It's wild. Like we're talking taking armdex and I mean just wild stuff that's like all that so you can look good in a Tik Tok. Where is your mom and dad? Cuz a lot of these people are really really young. A lot of these these are like children children.

[00:12:54]It's sad. It's really sad because I know for the longest time I'm going on a tangent here, but for the longest time it was so taboo for people in the fitness community to admit to taking these things. And you know, to a certain extent, I think it's good that people are a lot more upfront about their use and saying, "Hey, yeah, you know, um I look like this. Yeah, I work out. You got to work out to look like this. Um but I take these drugs, too." Um, I think it's good to admit that because a lot of people will look and, you know, try and do what you're doing and just be get frustrated or especially if you're selling something, you know, you got to be upfront and honest, right? Um, but I think also a lot of people have been like, "Oh, okay. Well, we're going to promote this now and we're going to show people how to do this and it's trickle down to young children and oh man, it is wild. It is wild." I I mean, that's the kind of thing that people will regret. I mean, because that has lasting permanent effects on your reproductive health, the stuff that they're abusing. You know, it's one thing to be, you know, an adult and you can make an informed consent, but to be a child and just have gone on this tangent from the internet, it's dangerous stuff, you guys. It's dangerous stuff. All right, guys. So, that about wraps up this weekend Q&A.

[00:14:05]Thank you so much for all of your wonderful questions and comments. I really appreciate them. This is a ton of fun. I really like this format because I feel like it's a little bit more conversational. Like I'm involving you guys more as opposed to just talking at you. I mean, I'm still talking at you, but you know what I mean? Like it's a little bit more of a back and forth kind of a thing. And I especially like that you guys are asking additional questions to go deeper on certain questions from past videos or like recent. So, I really like that too. Like the elastic waistband. You see how we we uncovered another layer. We uncovered another layer um about all things. You never knew the underwear could backfire, did you? Your underwear can be sabotaging your skin. Yeah, but you're not going to learn about that other places. You're not going to learn about that at Victoria's Secret cuz they're trying to sell you elastic waistband underwear.

[00:14:52]Okay? Don't bleach it. Don't bleach it.

[00:14:54]Anyways, guys, if you enjoyed today's video, give it a thumbs up, share it with your friends, and as always, don't forget sunscreen and subscribe. I'll talk to you guys tomorrow. Bye. Do people still shop at Victoria's Secret?

[00:15:06]I don't know. I do buy their underwear.

[00:15:08]You can buy their underwear on Amazon.

[00:15:09]Actually, this is TMI, but hey, you made it this far and I'm interjecting. I actually buy um they have this like four or five pack of basic black briefs, women's briefs from Victoria Secret. And I can attest, I've purchased now this package of five underwear, I want to say twice. And the longevity is amazing. The quality is really, really good. In contrast, the majority of quote unquote mall brands of things are just like the what once traditionally was more considered not luxury, but more on the high end, like you're going to pay a little bit more, but it was understood, you know, the the social contract was you're going to pay a little bit more, but you were going to get something very quality that would last. Those brands that still exist, Vera Bradley looking at you, quality is out the window. Price is still skyhigh. Price is still skyh high. can't speak for all of Victoria's Secret, but I will tell you that the black briefs that you can get from their store on Amazon, they are solid. Like I I can't do fancy jazzy doodly underwear.

[00:16:06]I just want basic boring underwear. I mean, it doesn't have to be granny panty level like but um I want comfort and I I don't I like black because you know it starts to get too many choices like no no no. So, highly recommend those. Um, but you know, they do have an elastic waistband, so wash accordingly. Be you you've The warnings have been laid out.

[00:16:28]The warnings have been laid out. All right, y'all.
