Recombinant human collagen as a skin booster: what it does, how it differs, and when we use it.
Most skin boosters work by delivering hyaluronic acid into the skin to hydrate and signal collagen production indirectly. Karisma is different. It uses recombinant human collagen, the actual building block, directly delivered into the dermis.
What recombinant human collagen is. Identical in structure to the collagen the body produces, manufactured through recombinant DNA technology rather than animal sources. There is no risk of allergic reaction tied to animal-derived collagen, and the structure is exactly what the dermis is built from.
How it differs from hyaluronic acid skin boosters. HA boosters add hydration and signal fibroblasts to produce more of the skin's own collagen and elastin. Karisma delivers collagen directly, supplementing the structural framework while also signalling regeneration. For clients whose primary concern is skin thinness and loss of structural support rather than hydration, this can be a better fit.
What it treats well. Mature skin showing thinning rather than just dryness. Crepey textures around the eyes, neck, and decollete. Clients who have not had as much success with hyaluronic acid boosters and want an alternative protocol.
A typical course is three sessions, two to three weeks apart. The injection technique uses multiple shallow points across the treatment area. Sessions are 30 to 45 minutes. Topical anaesthetic is applied for comfort. Tiny bruises at injection points sometimes appear and resolve within a few days.
Results build across two months as the delivered collagen integrates and the regenerative signal triggers the skin's own production. The cumulative effect is firmer, smoother, more youthful-looking skin with a quality rather than a volume change.
Who should consider it. Clients in their late forties and beyond with thinning skin. Anyone who has plateaued with hyaluronic acid boosters. Those who want a more structural, longer-lasting result than facials and surface treatments can deliver.
We discuss the choice between recombinant collagen and other boosters at consultation. There is no universal best, the right answer depends on what your skin needs.
