What are Rhytids? How do they show a good or bad response to Botox?

Rhytids are facial wrinkles, and they come in two forms:Static -- there at rest.Dynamic -- there only when moving the faceBotox is a great treatment for dynamic wrinkles because it relaxes the muscles that cause movement. Lines and wrinkles caused by muscle movement (dynamic wrinkles) can deepen and remain present even when the face is relaxed (static rhytids), often as a result of repeated facial expressions like smiling and squinting.Skin resurfacing procedures (e.g. lasers and chemical peels) are best for static rhytids.I hope this helps!

Botox can soften facial lines of animation and are most commonly used on the upper 1/3 of the face. If the ones are deep they may not flatten completely.
