Multiple factors are involved in the formation of wrinkles. These include chronological ageing, chronic sun damage, and smoking. Continued over contraction of certain muscles of facial expression, especially the frown lines at the glabella, the forehead, and crow’s feet, also contribute to the developments of wrinkles and frown lines. These underlying muscles can be safely weakened with the use of anti-wrinkle injections, which can help soften of these lines. To see sustained improvement, these injections can be repeated every 4 months or so.
Anti-wrinkle injections can form one part of managing skin ageing. Treatments are often combined. Depending on severity, treatments include: Sun protection & avoidance and Retinoid creams (mild), Anti-wrinkle injections and Volume enhancing injections (moderate), photodynamic therapy or other medical treatments for actinic keratoses, non-ablative lasers and intense pulse light advanced), and ablative laser resurfacing, and sometimes facial plastic surgery (severe).
