Assessing Brush Quality

Before purchasing brushes, you have to know what you are looking for and which brushes are worth-while investments. Assess the quality of the brushes by running your fingers through the bristles to make sure that they don't shed.
The brushes that come with most makeup compacts are too small and narrow for proper blush application. Toss them and use a brush specifically for that purpose instead.
Tips
Natural Bristles - natural bristles (such as squirrel, goat, pony or sable) are very soft and offer a more blended, natural application. They are best for applying powder-based products-blush, powder and eye shadow.
Synthetics Bristles - they are the best choice for applying creamy products such as concealer, gel liners, and lip colour. They are generally stiffer than natural hair and this helps in giving you greater control and more precise application.
