What it is
Lysophosphatidic Acid (LPA) is a bioactive glycerophospholipid mediator that signals through G protein-coupled LPA receptors (LPA1-6) expressed on keratinocytes, fibroblasts, and melanocytes; LPA1/LPA2 activation on fibroblasts stimulates cell proliferation, migration, and collagen synthesis — key wound-healing mediators; LPA3 on keratinocytes promotes differentiation and barrier protein expression (loricrin, involucrin, filaggrin); LPA5 on melanocytes modulates pigmentation signalling; autotaxin (an ectoenzyme on skin surfaces) generates LPA in situ from lysophosphatidylcholine; topical LPA or LPA precursors can supplement endogenous production; anti-apoptotic on skin cells under oxidative stress; inhibits hyaluronic acid degradation; particularly relevant for slow-healing, atrophic, or radiation-damaged skin; present in low concentrations in various plant seed oils; emerging research on topical application for skin renewal and barrier restoration.
