It's called "foundation" for a reason - it acts as a base for your makeup, a primer, sometimes it can double as a moisturizer. So it's important to spend some time finding one that enhances your skin. I've used few different types through the years, and have found that these are my go-to's.
I've been a devoted user of bareMinerals Matte Foundation for years. I have semi-oily skin, meaning that throughout the day it tends to get oily, some days worse than others. You could probably call it true "combination skin". I always apply it with the Handi Buki Brush and it goes on evenly without much effort. It provides light to moderate coverage, and has always delivered. I find that during the summer months it helps keep the
sweat oil at bay and keeps my face looking fresh. The color range is great for all skin tones. I also feel like the powder blends better than some liquid foundations so it's a little more forgiving if you deal with any uneven texture or blemishes. The only con is that it doesn't add moisture, so if you have some blemishes that need concealing be sure to use extra moisturizer around those spots.
More recently I have discovered Tarte Maracuja Miracle Foundation. There are always times I need a little more coverage, but I still want a build-able foundation. This does the trick. It applies well with a brush or a sponge, and doesn't settle in fine lines throughout the day. I like that one coat will be a light coverage, but I can add more in areas if needed. The best selling point for me was that it has natural ingredients. Bonus! The colors offered are good, not expansive, but good.
Another foundation that I have been using lately is the IT Cosmetics Your Skin But Better CC Cream. It has SPF 50+, and it claims to be packed with anti-aging ingredients to improve skin texture, brightness, and hydration. Let me tell you, I've been LOVING this CC cream. It truly covers more like a foundation - I'd say it's on the medium side of the spectrum. It blends so well, and works with any application method. I usually use my fingers to work it into the skin, almost like a moisturizer. I've also used the Sigma F80 and it works beautifully. I'm always left with a natural finish that stays put throughout the day. For my combination skin I always set with a finishing powder to help battle extra shine.
What recommendations do you have for a good foundation - drugstore or high end - can you tell a difference?
