Ablation of ferroptosis regulator glutathione peroxidase 4 in forebrain neurons promotes cognitive impairment and neurodegeneration

DSIP therapy aims to replenish and support these natural signaling levels

Topical peptides function as signaling molecules that communicate with fibroblasts and keratinocytes, stimulating: Collagen synthesis (types I, III, and IV) Elastin production Barrier repair and hydration retention Melanogenesis regulation (relevant to hyperpigmentation research) Key peptide classes studied in dermatology include: Peptide Class Example Primary Function Signal Peptides Palmitoyl Pentapeptide-4 (Matrixyl) Stimulates collagen and elastin production

These early steps lay a foundation for better long-term outcomes
