- Palmitoyl Tetrapeptide-7
- Inhibits IL-6 inflammatory signaling, reduces capillary permeability
- 6–8 weeks
- High. Reduces inflammatory edema by 25–35% in studies
- Moderate. Supports collagen integrity but doesn't rebuild volume
- Best for chronic puffiness tied to inflammation or allergies; requires consistent use at 3%+ concentration
- Acetyl Tetrapeptide-5
- Blocks glycation, restores dermal elasticity
- 4–6 weeks
- Moderate. Improves drainage but doesn't directly reduce fluid
- High. Measurably increases tissue elasticity and reduces AGE accumulation
- Strongest evidence for age-related bags where collagen glycation is the primary driver; ineffective for acute edema
- Copper Tripeptide-1 (GHK-Cu)
- Stimulates collagen synthesis, inhibits MMP degradation
- 8–12 weeks
- Low. No direct effect on fluid dynamics
- Very High. Increases dermal thickness and structural support
- Long-term structural repair; works synergistically with other peptides but requires stable formulation to avoid oxidation
- Retinoids (tretinoin, retinaldehyde)
- Increases cell turnover, stimulates collagen via retinoic acid receptor activation
- 12–16 weeks
- None. Can worsen irritation and fluid retention initially
- High. Proven dermal remodeling but slow onset
- Gold standard for photoaging but high irritation risk in periorbital area; requires prescription strength (0.025–0.05%) for meaningful effect
- Caffeine (topical)
- Vasoconstriction reduces capillary leakage; mild diuretic effect
- 15–30 minutes (temporary)
- Moderate. Immediate but transient reduction in puffiness
- None. Purely symptomatic, no structural benefit
- Useful for acute morning puffiness; effect dissipates within 2–4 hours; does not address underlying pathology
