Treatment Overview
Collagen Booster Injections are a regenerative dermatology treatment designed to restore firmness, elasticity, and smoothness to skin affected by stretch marks. Unlike fillers that add volume, collagen boosters use bio-stimulatory injectables such as PLLA (Poly-L-Lactic Acid, e.g., Sculptra), CaHA (Calcium Hydroxylapatite, e.g., Radiesse), PCL (Polycaprolactone), or PN/PRN (Polynucleotides like Rejuran). These stimulate fibroblasts to produce new collagen and elastin, gradually repairing the dermis.
In Korean dermatology clinics, collagen boosters are used on the abdomen, thighs, buttocks, breasts, arms, and hips to reduce the depth of stretch marks, improve skin thickness, and tighten lax areas. They are often combined with microneedling RF, Fraxel laser, or mesotherapy ampoules for maximum results.
Purpose & Benefits
- Stretch Mark Repair: Restores dermal thickness and smooths texture.
- Skin Tightening: Stimulates collagen remodeling for firmer skin.
- Improved Elasticity: Strengthens crepey or thin skin.
- Natural Regeneration: Gradual, long-lasting results from within.
- Dual Action: Treats both color (appearance) and laxity (tightness) of stretch marks.
