Botox injections are for both men and women that are looking to achieve or retain their youthful appearance. The majority of patients seeking treatment are at least 30 years old or older, but patients younger than that also seek out Botox as a proactive step in preventing wrinkles. If you have excessive skin laxity, Botox may not be able to produce noticeable results. If you have lines that are already imprinted or etched into the skin, Botox will help soften those lines, not completely erase them.
