Horizontal lines accross the forehead can be effectively treated with BTX (Botulinum Toxin A). This should only be done in conjunciton with a treatment of the glabella areas (vertical lines between the eyes and forehead) to avoid drooping of the eyebrows (ptosis).
Along with a reduction in visible lines (rhytides) on the forehead, appropriate placement of BTX can result in an aesthetic shaping of the eyebrows which can have the effect of making the eyes and forehead appear fresher and brighter.
During the procedure you should feel only minimal pinpricks as only very fine needles are used. The effect usually lasts between 4 – 6 months.
