Why doesn't botox work as well for those over age 65?

Botox may be less effective for individuals over age 65 due to several factors, including changes in skin elasticity and muscle strength that occur with aging. Older adults often have more pronounced wrinkles and sagging skin, which can affect how the treatment takes hold. Additionally, age-related alterations in facial anatomy and reduced responsiveness of muscles can diminish the overall results of Botox. Lastly, older patients may have a higher likelihood of underlying health conditions that could impact the efficacy of the treatment.
