Eye makeup brushes set come in many different shapes and sizes and sometimes it can be a little daunting to figure out what to use where. So to help simplify it a bit Niamh always says “Use the brush that fits the area”. So take eye brushes, for example, if it’s a small flat brush it’ll usually be suitable for your eye lid or lower lash line.
If it’s tapered or fluffy it’s usually suitable for your socket line. With face brushes, smaller brushes are used for detailing areas with highlighter or contour. Whilst larger brushes are suitable for larger areas of coverage like foundation or setting powder. Some brushes are made more durable than others for stronger areas of coverage, so avoid using a dense foundation brush for blusher or you’ll end up like Aunt Sally! In the same respect, trying to apply a foundation with a soft fluffy brush could out strain on the brush and pull the hair right out from the ferrule.
So to an extend read the description of each brush and once you’ve grasped what each brush is generally used for you can then adapt it to your style and technique.
