What is the difference between peptides vs retinol for skin research?
Retinol binds retinoic acid receptors and directly upregulates keratinocyte turnover, collagen synthesis, and pigmentation regulation. Peptides work through fibroblast signaling, gene expression, or angiogenic pathways depending on class. Different upstream me

- Retinol binds retinoic acid receptors and directly upregulates keratinocyte turnover, collagen synthesis, and pigmentation regulation. Peptides work through fibroblast signaling, gene expression, or angiogenic pathways depending on class. Different upstream mechanisms, overlapping downstream outcomes. Peptide research shows generally better tolerability; retinoids have more extensive clinical outcome data.
