Improved blood circulation: by stopping smoking, blood flow to the skin increases.Reduced oxidative damage: without the constant exposure to free radicals from cigarette smoke, the skin undergoes less oxidative stress, which slows down the ageing process.Collagen and elastin synthesis: over time, skin begins to rebuild its collagen and elastin reserves, improving firmness and elasticity.Improved hydration: skin becomes less dry, more hydrated, smoother and wrinkles are reduced.
