New 2026 Study: Laser Treatments Reverse Skin Aging at the DNA Level — What This Means for Your Skin

Most people think laser treatments improve how skin looks on the surface — smoother texture, less redness, fewer dark spots. That's true. But a study published this month in Scientific Reports (Nature Publishing Group) proved something far more significant: non-ablative laser treatments actually reverse the biological markers of aging inside your skin cells — at the DNA level.
This isn't marketing language. It's peer-reviewed science from one of the most respected journals in the world. And if you've been considering laser skin rejuvenation in Northville MI, this changes the conversation entirely.
What the Study Actually Found
Researchers conducted a controlled split-face study on 22 adults. One side of each participant's face was treated with a non-ablative fractional laser three times. The other side was left untreated for comparison.
Scientists then analyzed skin samples at multiple points: immediately after treatment, 1 month later, 3 months later, and 6 months after the final session.
The results were remarkable.
No significant changes appeared immediately after treatment — which is actually expected with non-ablative lasers. But at the 1-month mark, 635 biological change markers emerged in the treated skin. By 3 months, these effects expanded. By 6 months, they had stabilized into lasting results.
Most importantly: 83.9% of aging-related DNA changes were reversed by the laser treatment.
What "Epigenetic Aging" Means for Your Skin
Your skin ages in two ways. The first is physical — collagen breaks down, elastin weakens, texture changes. The second is epigenetic — the biological instructions that tell your skin cells how to behave gradually shift over time, and those shifts accelerate aging.
Think of epigenetics like software running on your DNA. As you age, the software becomes corrupted. Cells that once prioritized collagen production slow down. Inflammation pathways stay active longer than they should.
What this study proved is that non-ablative laser treatments can actually reprogram that software. The laser triggered changes in pathways related to:
Collagen organization — firmer, more structured skin
Epidermal differentiation — healthier, faster cell renewal
Stem-cell maintenance — your skin's natural repair system
Wound response regulation — controlled, sustained healing long after treatment
These aren't temporary effects. They're durable biological changes that kept developing for months after the last session.
Why Your Results Keep Improving After Treatment
One of the most misunderstood aspects of laser is the timeline. Many clients expect dramatic results after one session and feel disappointed when changes are subtle at first. This study explains exactly why that expectation is wrong — and why patience with laser is scientifically justified.
The biological remodeling triggered by laser doesn't happen overnight. It unfolds over weeks and months as your skin cells respond to the signals the treatment activated. The study found the most significant changes appeared 1–3 months after the final session and remained stable at 6 months.
That means every time you leave a laser session at Natural Lash Skin Bar in Northville MI, your skin is still actively improving long after you walk out the door.
What This Means for Aerolase Laser at Natural Lash Skin Bar
The Aerolase Neo Elite we use at Natural Lash Skin Bar in Northville MI is a non-ablative laser — the same category of technology validated in this research. It works deep below the surface while protecting the outer skin layer, making it one of the safest options available for all skin tones, including Fitzpatrick IV–VI.
Conditions Aerolase treats at our Northville studio:
Acne and active breakouts
Hyperpigmentation and melasma
Rosacea and persistent redness
Fine lines and early skin laxity
Uneven texture and tone
Now backed by peer-reviewed science showing non-ablative laser reverses aging at the biological level, Aerolase isn't just a cosmetic treatment — it's a clinically supported investment in your skin's long-term health.
How Many Sessions Do You Need?
Based on the study protocol and clinical experience, most clients see the best results from a series of 3–6 sessions spaced 3–4 weeks apart. This mirrors the 3-treatment protocol that produced 83.9% reversal of aging DNA markers in the study.
Results continue building for up to 6 months after your final session — meaning the investment you make today keeps paying off well into next year.
Frequently Asked Questions
Is Aerolase the same laser used in the study?
The study used a 1940-nm non-ablative fractional laser. Aerolase uses 1064-nm energy. Both are non-ablative — they work below the surface without damaging the outer skin layer. The collagen stimulation and biological remodeling mechanisms apply across non-ablative laser technologies.
Is Aerolase safe for my skin tone?
Yes. Aerolase Neo Elite is FDA-cleared for all Fitzpatrick skin types, including darker tones that are often excluded from other laser treatments. It is one of the few lasers we are fully confident using on every client, regardless of complexion.
Will I see results after just one session?
Most clients notice improvements in redness, texture, and brightness after their first session. The deeper cumulative results — the biological remodeling the study describes — build progressively over 3–6 months.
Is there any downtime?
None. You can return to your normal routine immediately after treatment. Some clients experience slight warmth or mild redness for a few hours, which resolves the same day.
Can Aerolase be combined with other treatments?
Yes. Aerolase pairs well with HydroFacial, microneedling, and other skin services. At Natural Lash Skin Bar, we build customized treatment plans based on your specific goals — not a one-size-fits-all approach.
Your skin is a long-term investment. And science just confirmed that non-ablative laser is one of the most effective tools available to protect it — not just on the surface, but at the cellular level.
