Botulinum toxin type A (e.g. BOTOX®) injections can help reduce lines and wrinkles which are caused by contractions of the underlying facial muscles every time you smile, laugh or frown. The more you laugh, smile and frown, the more prominent these wrinkles become as they gradually wear away the collagen in your skin. Botulinum toxin type A injections, better known as BOTOX®, and recently formally approved for cosmetic use under the name VISTABEL®, are prescription only medications, and should be administered by fully trained doctors.
