Microneedling at Merrion Medical Aesthetics Oakville
Microneedling – also known as collagen induction therapy – is a minimally invasive skin rejuvenation procedure that uses very fine needles to create controlled micro-injuries in the skin. These tiny punctures trigger the body’s natural healing response, boosting collagen and elastin production – the proteins that keep skin firm, smooth, and youthful.
By stimulating new collagen from within, microneedling helps improve skin texture and tone, reducing the appearance of fine lines, wrinkles, acne scars, hyperpigmentation, and even stretch marks over time. The result is a fresher, firmer complexion that still looks completely natural.
Unlike more aggressive laser or chemical peel treatments, microneedling preserves the surrounding healthy tissue, which means minimal downtime and a quicker recovery for you.
Our Oakville clinic performs microneedling in a safe medical setting under the guidance of Dr. Kate Healy (MD) and her trained team, so you can trust that you’re in experienced hands. We tailor each microneedling session to your skin’s needs – delivering rejuvenation while prioritizing your comfort and results.
What Is Microneedling?
Microneedling is a cosmetic procedure that harnesses your skin’s own healing ability to rejuvenate itself. The treatment involves a specialized device (often a pen-like tool) containing numerous ultra-fine, sterile needles that create microscopic punctures in the top layer of your skin.
Don’t let the needles scare you – these micro-injuries are so small that they won’t cause actual damage or scarring. Instead, they act as controlled stimuli that prompt your skin to produce new collagen and elastin in the treated area.
This process is why microneedling is frequently called collagen induction therapy, literally inducing your skin to remodel and renew itself.
By boosting collagen internally, microneedling helps smooth and firm the skin in a way that topical products alone often cannot. Over a series of treatments, it can soften fine lines and wrinkles, refine enlarged pores, fade the look of acne scars or stretch marks, and even out minor skin tone irregularities.
The popularity of microneedling has grown worldwide because it offers noticeable improvement with minimal invasiveness. Most people are good candidates for microneedling since it’s safe for all skin types and tones, including darker complexions that may not be suited for certain lasers.
At Merrion Medical Aesthetics, we use advanced microneedling technology to ensure precise, consistent results. The procedure is entirely non-surgical and performed right in our Oakville clinic.
If you’ve been researching what microneedling is and how it can refresh your appearance, our team is happy to explain the science and the beautiful benefits behind this treatment in more detail during your consultation.
How Does Microneedling Work?
Microneedling works by tricking your skin into repairing itself in targeted areas. When the fine needles create tiny channels in the skin’s surface, your body interprets it as minor damage and kicks into healing mode. This healing process involves releasing growth factors and sending fibroblast cells to the area to produce new collagen fibers and elastin.
Essentially, microneedling rebuilds and reinforces the skin from within, resulting in smoother, tighter, and more resilient skin texture over the following weeks and months. Because the needle pricks are so controlled and shallow, they predominantly affect the dermis (the collagen-rich middle layer of skin) without significantly damaging the outer epidermis.
This is why microneedling achieves collagen induction with very little actual injury to the surface – you get the benefits of a wound-healing collagen boost without the prolonged downtime associated with deeper peels or ablative lasers.
Another advantage of microneedling is that the micro-channels it creates can also enhance the penetration of topical serums or growth factors applied during treatment.
In our clinic, we may apply professional-grade serums (such as hyaluronic acid or vitamins) immediately after needling, allowing these actives to seep deeper into the skin through the temporary channels for added benefit. This combination further amplifies the rejuvenation effect.
Microneedling does not use any heat or harsh chemicals, so the risk of pigmentation changes or other side effects is minimal. In fact, unlike laser procedures that carry a small risk of causing hyperpigmentation (especially in darker skin tones), microneedling’s mechanical approach doesn’t trigger melanin issues, making it a versatile treatment for virtually all skin tones.
Overall, the mechanism is simple yet powerful: create tiny controlled injuries, let the skin heal itself stronger and smoother. Over a sequence of sessions, this process restructures the skin’s support matrix, yielding a noticeable improvement in firmness, fine lines, and scars.
One of the great benefits of microneedling is its versatility. This treatment can be done on the face, neck, and many other areas of the body that can benefit from collagen rejuvenation.
