INTERVENTIONAL
Treatment of Lateral Canthal Rhytides With Medium Depth Chemical Peel With or Without Pretreatment With Botulinum Toxin A: A Split-face, Rater-blinded Randomized Control Trial
This study is being done to find out if the use of botulinum toxin prior to a medium strength combination chemical peel (Jessner's peel followed by 35% Trichloroacetic acid peel) will improve the appearance of crow's feet wrinkles when compared to a chemical peel alone. Botulinum toxin type A is a purified substance, derived from a bacteria that block muscular nerve signals. Jessner's Peel, a combination of resorcinol (14g), salicylic acid (14g), and lactic acid (85%) in ethanol (95%), is a superficial chemical peel. These two products/procedures have been FDA approved to improve the appearance of facial wrinkles.

- Type: PROCEDURE
- Name: Chemical Peel Only
- Description: After cleansing the face with a pre-treatment cleansed composed of water and alcohol, the Jessner's peel solution \[a combination of resorcinol (14g), salicylic acid (14g), and lactic acid (85%) in ethanol (95%)\] will be applied to the entire face with a large cotton swab. The mixture will be left in place for a few minutes, and then the face will be wiped clean with water. Next, the TCA peel \[35% Trichloroacetic acid\] will be applied around the eyes. After leaving in place for a few minutes, cool, iced washcloths will be applied and the face will be wiped clean with water.
