- The table below compares sermorelin therapy to alternative interventions targeting skin elasticity, showing timelines, mechanisms, and realistic expectations.
- Sermorelin (200–500 mcg nightly)
- Stimulates endogenous GH → IGF-1 elevation → fibroblast activation and collagen synthesis
- 12–16 weeks for initial texture changes; peak at 24 weeks
- 12–18% increase in dermal collagen density
- Systemic, sustainable, requires consistent dosing and pituitary responsiveness. Not a quick fix
- Topical Retinoids (0.025–0.1% tretinoin)
- Upregulates collagen gene expression in keratinocytes; accelerates cell turnover
- 8–12 weeks for texture; 16–24 weeks for structural changes
- 8–12% increase in epidermal thickness
- Surface-level intervention. Works in tandem with sermorelin but doesn't address systemic decline
- Microneedling (1.5–2.5mm depth)
- Induces controlled dermal injury → wound healing cascade and neocollagenesis
- 4–6 weeks for initial plumping; 12 weeks for remodelling
- 10–15% increase in collagen I/III ratio
- Mechanical intervention. Synergistic with sermorelin but requires multiple sessions
- Exogenous HGH (2–4 IU daily)
- Direct GH replacement → IGF-1 elevation without pituitary involvement
- 8–12 weeks
- 15–22% increase in dermal thickness
- Faster than sermorelin but suppresses natural production; higher side effect risk (oedema, joint pain)
- Oral Collagen Peptides (10g daily)
- Provides proline/glycine for collagen synthesis; stimulates fibroblast activity via small peptides
- 5–8% improvement in hydration and elasticity
- Supportive but not sufficient alone. Works best alongside systemic interventions like sermorelin
