Dermal Fillers vs Skin Boosters: What is the Difference?
Published on June 5, 2026 • 4 min read
Hyaluronic acid is the darling of modern aesthetic medicine, prized for its unique ability to hold up to 1,000 times its weight in water. However, hyaluronic acid is utilized in two fundamentally different injectables: dermal fillers and skin boosters (such as Profhilo and Sunekos). Knowing which treatment fits your concerns is essential to achieving your desired outcome.
Dermal fillers are formulated using cross-linked hyaluronic acid. "Cross-linking" is a chemical process that binds the molecules together, turning the liquid into a stable, structural gel. This allows the filler to stay in place, hold its shape, and resist immediate breakdown. Because of this structural thickness, dermal fillers are ideal for physically filling hollows (like tear troughs), lifting cheeks, projecting a recessed chin, or adding definition and symmetry to thin lips.
Skin boosters, on the other hand, contain non-crosslinked hyaluronic acid. This formulation remains highly fluid, resembling a lightweight serum rather than a gel. When injected into the skin, it does not stay in one spot to add structural volume; instead, it diffuses smoothly across a wide area under the skin surface. Its main job is to flood the tissue with intense moisture, trigger the skin’s biological healing responses, and stimulate the natural synthesis of new collagen and elastin.
To put it simply: Dermal fillers change the shape, structure, and contours of your face by restoring lost volume. Skin boosters improve the quality, texture, bounce, and hydration of the skin tissue itself. Often, the most comprehensive and natural results are achieved by combining both approaches in a personalized treatment plan—restoring structural support with dermal fillers, and creating a luminous, healthy glow with skin boosters.
