after moisturizer and foundation, use a good LOOSE powder -- such as coty. get the scented -- not the fragrance-free. you'll fall in love with the scent.
dip your biggest blusher brush into the powder, dust your face gently all over. use a cotton puff to take off the extra. perfect finish.
for best hygiene, don't dip the brush directly into the coty box. remove enough powder for a month's worth of application into a container such as a pretty ceramic cup or small ramekin. this powder is very affordable and is the most perfect i've found.
