It does work - as quickly as 24 hours before you’ll see spots drying up and redness going down. However, the spray is very wet rather than a mist and you still have to reach where you sprayed it to rub it in. The bottle only sprays when held upright so it’s quite hard to cover everywhere as a result. The Murad one is more of an aerosol so is better to apply.
