Is the Rejuran Injection the Secret to ‘Glass Skin’?

The “glass skin” trend—characterized by a complexion so smooth, hydrated, and even-toned that it appears reflective—is often difficult to achieve with topical serums alone. Rejuran injections have become the “secret weapon” for this look because they address the skin’s structural integrity.

While makeup and highlighters create a temporary illusion of glow, Rejuran produces a biological glow. By injecting Polynucleotides (PN) directly into the dermis, the treatment restores the skin’s internal hydration levels and smooths out the micro-roughness that causes skin to look dull. When the skin surface is perfectly smooth and the internal layers are dense with collagen, light reflects off the face more uniformly, creating that hallmark “glass” finish.

To understand how Rejuran works, you have to look at the role of Polynucleotides (PN). These are DNA fragments derived from salmon, which are highly compatible with human skin. Unlike hyaluronic acid fillers that simply pull in water, PNs are “biostimulators.”

Once injected at Bella MD, these polynucleotides act as a signal to your body to start a repair process. They increase the proliferation of fibroblasts, which are the “factories” for collagen and elastin. As these structural proteins increase:

• The Dermis Thickens: This reduces the appearance of fine lines and “crepey” texture.
• Oil-Moisture Balance is Restored: Rejuran helps regulate sebum production, reducing the greasiness that can ruin a clear complexion while boosting deep hydration.
• Inflammation Subsides: By calming the skin’s inflammatory response, redness is reduced, leading to the clear, porcelain-like tone required for glass skin.

Because Rejuran relies on your body’s natural ability to heal and regenerate, the results are cumulative rather than instant. Most patients begin to see a noticeable improvement in skin texture and hydration within 1 to 2 weeks after their first session.

However, for the full “glass skin” effect—where pores are minimized and the skin achieves its maximum luminosity—we typically recommend a primary series of 3 to 4 sessions, spaced approximately 3 to 4 weeks apart. This timeline allows the skin cycles to refresh and the new collagen matrix to fully develop. After the second session, most patients report a significant “lift” in their skin’s radiance and a visible reduction in pore size.

One of the greatest advantages of Rejuran is that it changes the actual health of your skin, meaning the benefits are long-lasting. Once you have completed your initial loading phase of 3–4 treatments, the regenerative effects typically last for 6 to 12 months.

Because the skin is a living organ that continues to age and face environmental stress, we recommend a single maintenance session every 6 months at Bella MD. This “top-up” ensures that your collagen production remains optimized and your barrier remains strong, keeping that poreless, luminous glow consistent year-round.
