Skin aging occurs through two main processes: intrinsic (genetic) aging and extrinsic (environmental) aging. Intrinsic aging is natural and gradual, while extrinsic aging is primarily caused by sun exposure, pollution, smoking, and lifestyle factors. Signs include fine lines, wrinkles, loss of elasticity, uneven skin tone, and rough texture.
UV radiation from the sun is responsible for up to 80% of visible skin aging. Other contributing factors include decreased collagen production (starting in your 20s), reduced cell turnover, loss of hyaluronic acid, and environmental pollutants. Genetics, diet, and lifestyle choices also play significant roles.
A comprehensive anti-aging routine includes daily sun protection (the most important step), retinoids to stimulate collagen and cell turnover, antioxidants to neutralize free radicals, and moisturizers to maintain barrier function. Consistency is key—results take time and require ongoing maintenance. Start with lower concentrations and build tolerance gradually.
Sunscreen is non-negotiable—use it daily, even indoors and on cloudy days. Retinoids can cause initial dryness and sensitivity, so start slowly (2-3 times per week) and always use at night. Don't combine multiple active ingredients initially—introduce one at a time. Be patient; visible improvements typically take 3-6 months of consistent use.
If you're not seeing improvement after 6 months of consistent use, or if you're experiencing persistent irritation, schedule a follow-up. We can adjust your routine, consider prescription-strength options, or discuss in-office treatments like chemical peels or laser therapy for more advanced concerns.
