Clean your makeup brushes regularly!
Not only does it helps your makeup go on smoother, but it will get rid of old oxidized makeup that’s going back into your skin- which will make your makeup look too orange or pink. It will also help reduce breakouts.
Dirty brushes will harbor bacteria which can cause breakouts, or even skin irritations.
All you have to do is use your shampoo, and massage your brushes with it, and watch all the product come out in the sink. Every few times you can also use a conditioner to soften your brushes.
When drying them, lay them flat like in this picture, if you put them upright in a container the water will drip down into the base where the bristles are attached and can wreck the bond and you will have lots of hairs fall out. You can leave them in a room with a heater, not don’t put them in front of it, especially if you have synthetic brushes as the hairs will frizzle!
You can do this weekly or monthly depending on how often you wear makeup. I recommend foundation/concealer brushes be cleaned more often as they can become really hard to get out.
On a daily basis, you can use a brush cleaner, there are heaps of different ones. All pretty much the same ingredients, isopropyl alcohol and something to make them smell less potent. So If you don’t have a lot of money you can get the isopropyl spray from Bunnings for about $6.
I use a little bit of makeup remover and the spray on a tissue and rub my foundation/concealer brushes or anything that had a strong colour on them to clean them. For powder/blush/eye brushes I just use the spray on a tissue. You should do that every time after you use your brushes.
