IV Skin and Beauty

An IV skin-and-beauty drip is, almost without exception, a bag of saline with some combination of vitamin C, B vitamins, biotin, and (depending on the clinic) glutathione or NAD+. You sit in a chair for forty-five minutes, somebody in scrubs makes a fuss over you, spa music plays, you leave $250 lighter and tell yourself you can feel it working.

I don’t have a problem with the ritual. The ritual is fine, the ritual is doing real work, and the ritual would cost you nothing if you took a nap instead. The marketing is what bugs me. The marketing tells you the chemistry is doing the work and almost none of the evidence backs that up. The chemistry is along for the ride. What the bag is selling is permission to lie down in a quiet room with your phone unreachable, and in a culture where rest has to be justified, paying $250 makes the rest feel earned.

This whole corner of the industry got huge after the influencer wave hit aesthetic medicine, partly because somebody figured out that “glow” is a great word. Glow can mean anything, glow can’t be measured. If your skin looks the same after the drip, you weren’t glowing enough beforehand. If it looks better, the drip worked. It’s an unfalsifiable product, which is the dream business model.

The dermatology evidence for what works on skin is one of the most well-trodden in medicine. None of it is interesting. All of it works.

What’s actually in the bag

The big four, in roughly the order they show up on a menu:

Vitamin C, usually 5 to 25 grams. You can absorb maybe 200mg of it orally before your gut hits a ceiling, so IV does get more of it into the bloodstream, the question is what the bloodstream does with it. For sepsis and certain oncology stuff there’s a real conversation. For “glow” there’s no decent trial showing IV vitamin C does anything to skin texture or tone that you wouldn’t get from eating a kiwi, and eating a kiwi is fun.

Biotin is sold as the hair-skin-nails vitamin. Real biotin deficiency does cause hair loss and brittle nails, and real biotin deficiency is rare unless you’re on certain seizure meds or have a specific genetic enzyme issue. Giving biotin to somebody who isn’t deficient does nothing for their hair. It does screw up thyroid lab tests and troponin assays (the blood test ERs use to look for heart attacks), which is how a few people have ended up getting worked up for heart attacks they weren’t having… which is the kind of complication you don’t read about in the drip menu.

Glutathione is the big one in Asian beauty markets and increasingly in the US, sold for skin lightening. Whether anyone gets to say that out loud or not, that’s what it’s marketed for. The US FDA has been clear that no approved injectable glutathione products for skin whitening exist, the stuff on the market is unapproved and often compounded in places nobody is watching closely, and the agency has flagged contaminated batches, unknown purity, and infection risk from these products. This is not “wellness.” This is an off-label cosmetic injection of an antioxidant whose safety profile at these doses has never been properly worked out.

NAD+ is the newest entrant, sold as anti-aging. It’s a coenzyme involved in how your cells make energy, the animal data on NAD precursors is genuinely interesting, the human data on IV NAD+ for any cosmetic outcome is essentially zero. It’s also famously uncomfortable to infuse, and the clinics will tell you that’s “the cells working.” That’s a marketing rephrase of “we’re pushing it in too fast.” Slow the infusion down, the burning eases. Mitochondria have nothing to do with it.

What’s actually selling

The kind of guy who shows up after eighteen months of weekly drips, paying for vitamin C and glutathione and “the works,” when you ask him what he thinks he’s getting, usually says something like… it’s the only hour of the week his phone can’t reach him. Slack doesn’t follow him into the chair, the nurse is kind, the room is dim. Meditation apps felt like another thing to fail at. The drip doesn’t ask anything of him.

That’s the actual product, the chemistry is along for the ride. He’s buying a permission slip to lie down in a quiet room. In a culture where rest needs a receipt, paying $250 makes the rest feel earned. Worth saying out loud, because the bag is taking credit for what the nap is doing.

The nurse, the dim room, and the phone-free hour are doing the work. The bag is just the receipt that lets you take the nap.

The influencer side of it is a separate machine. Somebody with great skin posts a video of their drip, the implication is that the drip caused the skin, and the actual cause (genetics, twenty years of sunscreen, a dermatologist, ring light, retouching) doesn’t make it into the caption. Photogenic, vaguely medical, unfalsifiable… a service that checks all three of those boxes is going to sell whether the chemistry is doing anything or not.

What actually changes skin

The dermatology evidence for what works on skin is one of the most well-trodden in medicine. None of it is interesting. All of it works.

For hair specifically, the things that actually work are finasteride and minoxidil, which have decades of randomized data behind them, and neither is sexy enough to advertise on Instagram. Biotin drips will not regrow hair. They will give the wellness clinic your $200.

Treating underlying skin conditions is where most people get the biggest wins. Acne, rosacea, melasma, perioral dermatitis, seborrheic dermatitis. These are diagnosable conditions with actual treatments, and people will spend $3,000 a year on drips and have never seen a dermatologist for the rosacea that’s been giving them the red cheeks the drips are supposedly fixing. Your uncle who knows a guy and your cousin’s hair stylist are not the right consults for this.

The risk side nobody mentions

Most drips are fine. Most isn’t all. You’re getting an IV from a nurse who may or may not be supervised by a physician, in a setting that may or may not have crash equipment, with a compounded product that may or may not be what the label says. The compounding pharmacy side of the cosmetic IV industry has had multiple recalls, contaminated batches, and FDA warning letters over the last few years.

Bloodstream infections from IV access in non-medical settings are real and underreported. Allergic reactions to high-dose vitamin C have happened. Glutathione has the FDA warnings already mentioned. NAD+ infusions done too fast cause chest tightness, nausea, and a racing heart that look exactly like a panic attack and have sent people to the ER more than once. None of that means a drip is going to hurt you. It means the risk-to-evidence ratio is not great. You’re accepting a small but real medical risk in exchange for an outcome that has essentially no data behind it.

What I tell people who ask

If the ritual matters to you and you can afford it, go get the drip. I’m a provider, not a parent, and the appointment is yours. Just know what you’re paying for, which is an hour in a quiet room with a kind person and cultural permission to rest. That’s a real product, and it’s worth something. It’s just not a medical product, and it shouldn’t be priced or marketed like one.

If your goal is actually better skin, the money is better spent on a dermatologist appointment, a tube of tretinoin, and a bottle of sunscreen you’ll actually use. Total cost under $150, the change shows up in photos over six months, and nobody is going to make a TikTok about it… which is part of why it works and the drip doesn’t.
