I do this everytime. On everyone. It works everytime. Prior to makeup application... Spay skin with either a moisturising toner or fix plus. This might be the only moisturiser you need for oily skin, otherwise while the skin is still wet apply a primer or moisturiser, but not both. Remember, skin can be too dry, too matte, too oily, too shimmery, but never too hydrated. The middle ground is always the best place, which is why i use a toner or fix plus first, because everything goes on better. On a sub-note, MAC Prep and Prime SPF50 is a great primer/moisturiser. It actually leaves a matte finish but you don't get a lot of product, so if you're gonna use this for you only source of sunscreen PLEASE make sure you use enough to get protection (even if your foundation contains SPF). 10 Steps. 1. Foundation. Apply with your favourite method to the entire face. I tend to use a brush and then a damp sponge. I'm a fan of bobbi brown stick foundation (melted), MAC Stuido Tech (melted) and Eve Pearl HD foundatoin for very mature skin. 2. Concealer. Apply under the eyes. If apply regular concealer make sure it is the same shade as your foundation. If applying corrector, pink tones work best for fair to medium tones, and peach for medium to dark tones. 3. Powder. Apply with either a puff or brush. I like loose but tend to travel with pressed. MAC Skin Finish Natural is amazing. 4. Bronzer. I like to apply to the outside parts of the face. Don't go mad. I like Bobbi Brown correctors ...
