Exosome Microneedling in Houston

Exosome microneedling pairs two things. First, a PromoItalia microneedling pass, which is the part that actually does the work on your skin. Second, a topical exosome serum I apply onto the surface after the channels are open, which some patients choose as a post-procedure support step. I want to be plain about the order there, because the microneedling is the treatment and the exosome serum is an adjunct layered on top of it. Nothing gets injected.

I also want to be honest up front about where the science sits. Exosome products are a newer category, the regulatory picture is still evolving, and the FDA has cautioned the public about unapproved exosome products sold with big therapeutic promises. So you will not hear me make disease-treatment or "regenerative cure" claims on this page. What I can describe is how I use the serum in practice, honestly and with the hedges it deserves.

Considering exosome microneedling in houston? Start with a consultation.

What it treats

  • Overall skin texture and tone (driven mainly by the microneedling)
  • Fine lines and early surface lines
  • Dullness and loss of skin radiance
  • Post-procedure redness and recovery, as a support step some patients add
  • Sun-stressed skin that has lost some of its bounce

Products used in this treatment: PromoItalia 1NEED PRO microneedling device (FDA-cleared), Promoitalia topical exosome serum (applied post-procedure, not injected)

What the microneedling part actually does

The microneedling is the engine here, so let me start there. When the 1NEED PRO cartridge passes across your skin, its needles create thousands of microscopic channels into the superficial dermis. Your body reads each one as a tiny wound and starts the normal wound-healing cascade - platelets release growth factors, fibroblasts migrate in, and new collagen lays down over the following weeks. Microneedling on its own is a well-studied way to nudge that collagen response without the downtime of laser resurfacing.

A clinical aside on timing. New collagen does not appear overnight; most of it forms across roughly 4 to 12 weeks after a session, which is why I tell people not to judge a single treatment at the two-week mark. The glow you see early is largely hydration and inflammation settling. The structural change comes later, and it is subtle.

The exosome step, described honestly

Exosomes are tiny extracellular vesicles - little packets that cells release, carrying a mix of signaling material. The PromoItalia exosome serum is a topical cosmetic preparation, not an injectable and not an FDA-approved drug. I apply it onto the skin after the microneedling pass, while the channels are still open, on the theory that the open surface lets more of it sit where it can do something.

Here is the honest framing. Some patients choose to add the exosome serum because they want extra post-procedure support and they like how their skin feels in the days after. The published human evidence for topical exosomes is still maturing, the products are not standardized across brands, and I cannot promise you a specific outcome from the serum itself. A second clinical aside: most of the measurable benefit you get from this appointment comes from the microneedling. The exosome layer is a reasonable add-on for people who want it, not a substitute for the needling.

If that careful tone sounds like hedging, it is. I would rather you decide with clear expectations than oversold ones. We talk through it at consult, under the medical direction of Danna Qunibi, MD, and you are welcome to skip the exosome add-on entirely and just do the microneedling.

Who tends to be a good candidate

Good fits are usually people who want general skin-quality work - texture, tone, a fresher surface - and who are realistic that this is a gradual, stacking process rather than a one-and-done fix. Healthy skin with no active infection or open breakout in the treatment area is the baseline.

I hold off, or refer out, in a few situations. Active acne flares, cold sores in the area, certain skin conditions, recent isotretinoin use, pregnancy, and a history of keloid scarring all change the conversation. People prone to post-inflammatory pigment need a gentler plan and strict sun habits afterward. None of that is meant to scare anyone off; it is just the screening I do before we book.

Downtime and what the days after look like

Plan on a pink, flushed face for the rest of the treatment day. Some patients have light pinpoint bleeding for an hour or two right after. Redness usually settles over about 1 to 2 days. By 48 hours most people look close to normal, and any visible glow tends to show up around day 7 as things calm down.

For the first 24 to 48 hours I ask people to skip makeup, harsh actives (strong retinol, glycolic, high-strength vitamin C), hot yoga, saunas, and heavy sweating. Gentle cleanser, bland moisturizer, and sunscreen. That is most of the aftercare. Everyone heals a little differently, so your timeline may run shorter or longer than the averages I just gave.

How this compares to the PDGF and Mermaid Facial options

The microneedling device is the same across all three. What changes is the serum I pair with it, and I pick based on your goal at consult.

  • Ariessence Pure PDGF is a single, well-characterized growth factor at a consistent concentration. Its appeal is predictability - the same dose every time - and I lean on it as a reliable post-procedure topical, especially when recovery support is the priority.
  • The Mermaid Facial pairs the microneedling with a salmon-derived polynucleotide serum plus hyaluronic acid and glutathione. It is my go-to for general radiance and that lit-from-within look before an event.
  • Exosomes carry a broader, less standardized signaling payload than a single growth factor. Some patients specifically want to try them for post-procedure support. The trade-off is exactly that newer, still-maturing evidence base I described above.

In practice I use all three depending on the person and the goal, and plenty of treatment plans rotate serums across a series. There is no single right answer, which is why I would rather match it to you than push one option.

Houston-specific notes and pricing

Sun protection matters more after microneedling than people expect, and it matters even more here. Freshly needled skin is temporarily more vulnerable to UV, and a Houston summer does not go easy on it. Daily broad-spectrum SPF and a real effort to stay out of direct sun for the first week help protect your result and lower the odds of post-inflammatory pigment, which our climate and a lot of our patients' skin tones make worth taking seriously. Our humidity is the one upside - skin tends to stay less parched while it heals, though heavy summer sweating in the first 48 hours is still something to avoid.

On price, I quote at consult rather than online. The total depends on whether you add the exosome serum, whether we are doing a single session or a series, and what your skin actually needs. I would rather give you an honest number tied to a real plan than a teaser figure that changes once we talk. We are at 2401 N. Shepherd Dr., Ste. 229, at the corner of 24th and Shepherd in the Houston Heights, just south of I-610, with free parking under the building.

Common questions about exosome microneedling in houston

Are the exosomes injected?
No. The exosome serum is applied topically onto the skin after the microneedling pass - it is not injected and it is not an FDA-approved injectable. The microneedling itself is what does the main work; the serum is a surface-applied support step some patients choose to add.
Do exosomes really work?
Honest answer: the science is still maturing. Topical exosome products are a newer category, are not standardized across brands, and the FDA has cautioned about unapproved exosome products sold with therapeutic claims. I do not make disease-treatment or cure claims about them. Some patients add the serum for post-procedure support and like how their skin feels afterward, but most of the measurable benefit from this appointment comes from the microneedling.
How is this different from the PDGF add-on or the Mermaid Facial?
Same microneedling device, different serum. Ariessence PDGF is a single growth factor at a consistent dose, which makes it predictable. The Mermaid Facial uses a salmon-derived polynucleotide serum aimed at radiance. Exosomes carry a broader, less standardized signaling payload with a newer evidence base. We pick at consult based on your goal.
How long is the downtime?
Plan on a pink, flushed face for the rest of the day, with redness usually settling over about 1 to 2 days. Some patients have light pinpoint bleeding right after. Skip makeup, harsh actives, saunas, and heavy sweating for the first 24 to 48 hours. Everyone heals a little differently.
Can I just do the microneedling without the exosome serum?
Yes, absolutely. Microneedling stands on its own and is the part doing the work. The exosome serum is an optional add-on. Many patients do a first session without it, see how their skin responds, and decide about add-ons from there.
How much does it cost?
I quote at consult rather than posting a price online, because the total depends on whether you add the exosome serum, single session versus a series, and what your skin needs. We talk through an honest number tied to a real plan when you come in.
