Collagen and Skin Firmness in Montréal: What to Know

Think of collagen as the skin's internal scaffolding. It gives the dermis structure, helps skin resist stretching, and supports the even surface we associate with healthy skin. Hyaluronic acid, another natural component of the skin, works alongside it by holding water within the tissue, which keeps skin hydrated and supple (Zhou & Yu, 2025).

Because this support system thins gradually, the changes tend to appear slowly: fine lines, rougher texture, and skin that feels less firm than it used to.

Several treatments are designed around exactly this idea. Rather than adding something that sits under the skin, they aim to stimulate the skin's own repair response so that new collagen forms gradually.

Microneedling uses very fine needles to create controlled micro-injuries in the skin, which trigger the body's natural repair process. A 2025 systematic review of microneedling for facial rejuvenation found improvements in skin texture, fine lines, and overall appearance across the included studies, with side effects that were generally mild and temporary, such as short-lived redness (Foppiani et al., 2025).

Biostimulators are injectable treatments made of collagen-stimulating particles, such as poly-L-lactic acid. The carrier liquid is absorbed while the particles encourage the skin to build its own collagen over weeks and months. A 2024 systematic review found that several studies reported increased dermal thickness and improved firmness after poly-L-lactic acid treatment, with effects in some studies maintained for two years or longer. The same review cautions that the overall quality of the evidence is still low, and that side effects such as bruising, tenderness, and small nodules can occur (Signori et al., 2024).

Topical retinoids are vitamin A derivatives used in skincare. A 2022 systematic review of randomized controlled trials found that topical tretinoin, a prescription retinoid, improves the appearance of photoaged skin over time (Sitohang et al., 2022).

Collagen-stimulating treatments share one trait: they work gradually. Changes build over weeks to months rather than days, and a series of sessions is often recommended rather than a single visit. They also share a second trait: results vary. Your age, skin, lifestyle, and sun exposure all influence how much improvement you will see, and no treatment can stop the underlying process of ageing.

If you have noticed a change in firmness or texture, the first step is a conversation. We can assess your skin, explain which collagen-supporting options fit your situation, and build a plan with realistic expectations attached.
