Even before mineral makeup was introduced to the market, loose powders have been there for quite a while, as something to set makeup. Loose powder was also something that is worn by those who have flawless and low maintenance skin to begin with, just to give it a more polished and neater look.
There are also loose powders that promise superb oil control properties that control shine all throughout the day. But most of the time, loose powders are there to set makeup. Specially for full coverage makeup, when a liquid, or cream foundation is used, the loose powder is used last to make the skin feel velvety, smooth, polished, and all even.
Good thing that mineral makeup is here, with ingredients helpful to the skin and non-comedogenic, as well as non-harming to the skin with the absence of the ingredient talc. For my makeup schooling, when they ask me to get loose powder, I just whip up whatever mineral loose powder I have to use on my model, because mineral loose powder, in my opinion, can be more fine, skin friendlier, and can dew up into a fabulous, dewy finish as skin oxidizes as minutes or hours pass by.
The technique taught to me was, after applying liquid or cream foundation, use a powder puff to apply generous amounts of loose powder ( or rather, loose mineral powder , translucent in shade ) for the even layer of cream foundation-applied base to smoothen up and set ( just make sure that the layer is already very even ), and as the loose mineral powder absorbs the cream, it sets the makeup to that, to stay for the whole day. Use a big powder brush to make sure that loose mineral powder is applied evenly as well.
I’m just so glad that I can get in mineral makeup my routine in makeup school, still! I’ve been studying really hard, yknow!
