Can Peptides Improve Skin Aging?

Systematic review reports gains in hydration, brightness, and wrinkles, with stronger evidence for oral vs topical formulations

1

Peptide-based therapies show modest improvements in skin aging signs, particularly hydration, brightness, and wrinkle appearance.
2

Oral peptide formulations demonstrated stronger evidence of effectiveness compared to topical therapies in improving skin hydration and wrinkle reduction.
3

Peptides may enhance skin structure by stimulating collagen synthesis and supporting extracellular matrix integrity.
4

Peptide therapies were generally well tolerated, with mild gastrointestinal discomfort noted, but no serious safety concerns were reported.
5

Further standardized research is needed to confirm peptide efficacy and establish consistent outcome measures across studies.
