- Oral Collagen Peptides (Glow Stack)
- 7–10 days
- Peaks at weeks 8–12
- 8–12 weeks residual effect
- Systemic delivery; requires consistency through week 12 for structural benefits
- Topical Retinoids
- 2–4 weeks
- Visible at 12–16 weeks
- Returns to baseline within 4–6 weeks
- Surface-level remodeling; does not increase dermal collagen density systemically
- Hyaluronic Acid Serums
- 24–48 hours
- No collagen synthesis
- Immediate loss upon cessation
- Temporary humectant effect; no structural change
- Vitamin C + Peptide Serums
- 3–7 days
- Minimal; primarily antioxidant
- 2–3 weeks
- Surface protection; limited dermal penetration for collagen stimulation
- Microneedling + Topical Peptides
- 1–2 weeks
- 6–8 weeks with repeated sessions
- 6–8 weeks
- Enhances peptide penetration but requires clinical setting and downtime
