1. If you are using mineral concealer and foundation, you may want to apply concealer over the foundation, as you might buff it away if applied before foundation.
2. Use a flat top kabuki for heavier application. Rounded top for applying lighter layers.
3. Many shadows can double as a brow powder and also eyeliner. Yes, visine works great as a wetting medium.
4. Many shadows, blushers and bronzers can serve multiple purposes as lip color, cheek color, eye color. Just be sure to read the labels to check for lip safety.
5. Ingredients: be aware that "made with minerals" can mean just pigment, or just one ingredient. Ingredient lists are listed in order of predominance.
SPF ingredients: FYI if a company claims SPF protection then the cosmetic becomes a drug and must meet stringent drug manufacturing laws. Plus, once a drug, the amount of sunscreen ingredients are limited. Not so if it's a cosmetic with no SPF claims. So a foundation with no SPF claim may have more protection than one that does claim it! Confusing, I know. Sorry
Point is don't assume there's no SPF protection, simply because it isn't claimed. Read the ingredients, and if you really want to investigate, ask the manufacturer what the percent of SPF ingredients is.
