What's Actually In There: You've seen the names. Nobody's ever explained them. Let's fix that.
Ingredient lists love to make skincare feel harder than it is. A few impossible-to-pronounce names, a wall of claims, and suddenly you're expected to know which serum goes before which cream — and whether any of it can even be layered together.
Vitro takes the opposite approach. The K-Beauty Balm is built around six primary actives, each chosen for a specific job: visible lines, lost firmness and volume, dark spots, dullness, barrier damage, and the structural changes that make skin look less lifted over time.
And instead of asking you to stack them across half a shelf, Vitro puts them in one solid stick, then uses its Bio-Magnetic Cationic Lock to keep the formula in sustained contact with skin for up to 12 uninterrupted hours per application.
Six primary actives. One swipe. A lot less shelf space.
Your routine doesn’t need more steps.
It needs the right actives, in one place, long enough to do their jobs.
01
PDRN (Sodium DNA)
The one Korean clinics gatekept.
If skincare TikTok has crossed your feed lately, you've probably met Rejuran: the salmon DNA injectable Korean clinics kept under-the-radar for years, right up until the internet found out and lost it.
PDRN is the ingredient behind the hype. Sodium DNA is the version you can put on your face at home, in a balm, with no appointment and no needle.
In Vitro, Sodium DNA (PDRN) is positioned as a marine-derived cellular DNA activator that supports cell renewal and helps rebuild the look of deep tissue density. That matters when aging looks less like one obvious line and more like hollow under-eyes, softer cheek contours, thinner-looking neck skin, or that 'where did the volume go?' feeling.
Vitro pairs PDRN with Hydrolyzed Collagen for a more complete volume-and-structure story — and the 12-hour cationic lock keeps PDRN in continuous contact with skin instead of treating it like a quick rinse-on, rub-off step.
Best for: Hollow-looking under-eyes, loss of volume, thinner-looking skin, and structural deflation.
Clinic-famous ingredient. No appointment required.
Bakuchiol
Retinol results, without making retinol your whole personality.
Bakuchiol is Vitro's high-potency retinol alternative. It activates retinoid receptors to support Type I and III collagen synthesis and cellular turnover — the same big reasons people reach for retinol in the first place.
The difference? In the 12-week head-to-head trial cited in Vitro's master positioning, Bakuchiol delivered results equivalent to retinol without the same side-effect story. That's a very different proposition if your skin has spent years telling traditional retinoids 'absolutely not.
In Vitro, the cationic lock holds Bakuchiol against the skin for the full 12-hour window, giving that collagen-signaling story sustained contact instead of a quick cameo.
Best for: Fine lines, deeper wrinkles, crow's feet, expression lines, neck rings, and loss of firmness — especially if traditional retinoids aren't your thing.

Still trying to “work up” to retinol?
Vitro gives you a different route to the collagen story — without adding another serum to the lineup.
03
THDA Vitamin C
The vitamin C that actually wants to go deeper.
Tetrahexyldecyl Ascorbate — THDA if you're not trying to win a spelling bee — is an oil-soluble, lipid-stable Vitamin C derivative. Vitro's master positioning cites it as penetrating three times deeper than standard ascorbic acid.
Why care? Because dark spots and sun damage aren't just surface-level problems. THDA is positioned to reach deeper, support collagen synthesis, and inhibit melanin production at the source while staying stable instead of turning into that sad orange serum at the back of your cabinet.
It also works alongside Niacinamide and Licorice Root in Vitro's broader brightening system, so your tone isn't being handed off to one ingredient and told 'good luck.
Best for: Dark spots, sun damage, post-acne marks, dullness, uneven tone, and oxidative collagen loss.
Three times deeper than standard ascorbic acid — without the oxidation drama.
Niacinamide
The overachiever. And yes, it earned the title.
Niacinamide is one of those ingredients that refuses to pick one lane. In Vitro, it's there to help rebuild the intercellular lipid barrier, inhibit melanin transfer, minimize the look of pores, and calm visible redness and inflammation.
It's also government-certified for brightening in South Korea, which means the tone-evening story isn't just there because 'glow' looks good in a headline.
The Bio-Magnetic Cationic Lock keeps Niacinamide against the skin barrier for 12 uninterrupted hours, while Ceramide NP backs it up on the barrier side and THDA Vitamin C + Licorice Root round out the brightening side.
Best for: Blotchy tone, dark spots, visible pores, redness, rough texture, sensitivity, and a compromised barrier.

05
Ceramide NP
The one keeping the whole operation sealed.
Ceramide NP directly replenishes the skin's lipid barrier, helping seal moisture in and irritants out across the full 12-hour wear window. It's bioidentical to ceramides naturally present in human skin, which is exactly why it makes sense in a formula built for dry, reactive, overworked skin.
Here's where Vitro gets interesting: the Bio-Magnetic Cationic Lock creates the electrostatic hold, while Ceramide NP creates a second physical occlusive seal. Two different mechanisms, same mission — keep the formula against your skin and help stop moisture from making an early exit.
Best for: Chronic dryness, crepey texture, reactive skin, redness, irritation, and a barrier that feels like it has officially clocked out.
Dry again by morning?
Vitro doesn’t treat barrier support like an afterthought. It builds it into the same swipe as the rest of your actives.
Hydrolyzed Collagen
The structural one.
When skin starts looking less lifted, the issue isn't always 'more wrinkles.' Sometimes it's the bigger architecture: a softer jawline, thinner-looking neck skin, deeper folds, or the kind of deflation that makes everything look a little less supported.
Vitro uses low-molecular-weight Hydrolyzed Collagen peptides to support structural firmness in the jawline and neck. The master positioning frames it as replenishing structural protein that free-radical oxidation has been breaking down over time.
It works in tandem with PDRN: Hydrolyzed Collagen handles the structural protein side, while PDRN supports deeper tissue density. And because protein signaling needs sustained contact, Vitro's cationic lock keeps those peptides flush against the target area for the full 12-hour window.
Best for: Sagging, thinning, neck rings, deeper folds, loss of firmness, and skin that looks structurally deflated.
Not every sign of aging is a line. Some of it is structure.

Why Six Actives Work Better Than Six Separate Steps
Any one of these ingredients could headline a serum. Vitro's point is that your skin concerns usually don't show up one at a time — so why should your routine?
Bakuchiol goes after the collagen-and-wrinkle story. PDRN and Hydrolyzed Collagen tackle volume and structural density from complementary angles. THDA Vitamin C and Niacinamide cover pigmentation and tone. Ceramide NP helps rebuild and seal the barrier around all of it.
Then the Bio-Magnetic Cationic Lock does the part most routines don't talk about: keeping that active-rich formula in sustained contact with skin for 12 uninterrupted hours per application.
It’s not six serums in a trench coat. It’s one formula designed as a system.
Meet the Balm
One solid stick. No tools. No fingertips. No five-minute layering spreadsheet.
Swipe Vitro onto under-eyes, expression lines, crow's feet, jawline, neck, or wherever you want targeted support. In the morning, it blends under or over makeup. At night, use it as your final step on clean skin. The cationic matrix anchors the formula through the full 12-hour wear window.
Six primary actives. One swipe.
If your shelf is crowded but your results still feel scattered, this is the edit.
