Genetic and Metabolic Targeting: The development of cell-specific ferroptosis loss-of-function models (e.g., epithelial- or immune-specific GPX4 or ACSL4 knockout systems) will enable precise dissection of compartment-specific contributions to inflammation and metabolic dysregulation

Stimulates collagen and elastin production estriol and GHK-Cu both independently activate fibroblasts to rebuild the skin's structural proteins, while tretinoin further drives collagen synthesis through retinoid receptor signaling 1 2 3 Reduces fine lines and wrinkles research on 0.3% topical estriol, tretinoin, and GHK-Cu has each independently shown measurable reductions in wrinkle depth and surface area 1 2 5 Improves skin thickness and density topical estriol counteracts the epidermal thinning associated with estrogen deficiency, and GHK-Cu has been shown to increase dermal density and firmness 1 6 Enhances skin hydration and barrier function estriol boosts hyaluronic acid production, niacinamide supports ceramide synthesis, and tretinoin improves the stratum corneum's ability to retain moisture 4 7 Evens skin tone and reduces hyperpigmentation tretinoin normalizes melanocyte activity and speeds cell turnover
