There are two aspects to the question of whether it is better to inject hyaluronic acid or botulinum toxin for Kawasaki lines. Kawasaki lines are wrinkles on the face, and the formation of Kawasaki lines is related to the interbrow complex. The interbrow complex is mainly composed of the descending interbrow muscle between the eyebrows, and the descending brow muscle under the head of the eyebrows and the frowning muscles on both sides, so Kawasaki lines are comprehensive wrinkles. If Kawasaki lines are true wrinkles, in addition to filling with hyaluronic acid, Botox is needed to relax the muscles of the interbrow muscle complex. If the lines are pseudo-wrinkles, only Botox is needed to relax the muscles of the interbrow muscle complex, and regular injections are needed. Therefore, for the treatment of Kawasaki lines, patients need to go to a regular hospital and see a qualified dermatologist for treatment, and they must pay attention to sun protection after the treatment.
