Background: BB creams (also known as blemish balms) started off as after-treatment balms for patients who underwent laser surgery. Because they helped regenerate damaged skin and provided protection, BB creams became a natural alternative to pore-clogging liquid foundations, and South Korean cosmetics companies became the first to make BB creams available to a wider market.
About BRTC: Among the reputable South Korean brands to manufacture BB creams (such as Dr. Jart, Gowoonsesang, Etude House, Missha, The Face Shop, Skinfood, Hanskin, Skin 79, etc.), BRTC BB creams became favorites for their healing properties, finish, oil control, and coverage. So far, BRTC produces five types of BB creams: Perfect Blemish Balm, Perfect Recover Balm, Whitening & Wrinkle Repair, Perfect Protect Balm, and Perfect Soothing Balm.
EDIT: I've been told Perfect Blemish Balm has been discontinued due to copyrighting purposes. BRTC has released a couple new BB creams - all equipped with the now-standard whitening, anti-wrinkle, and SPF - most likely to stay competitive with the plethora of creams on the market. I'm not certain, but I'd guess there are about 4-5 new BRTC BB creams out?
My Review: After fawning over Korean actresses' perfect porcelain skin, I finally gave in and bought the BRTC Perfect Blemish Balm after a friend recommended it to me. The consistency of the Perfect Blemish Balm is quite thick - thicker and creamier than most liquid foundations or tinted moisturizers I've tried; however, it's still blendable and easily spreadable.
The coverage is absolutely amazing. Before using BB creams, I used Bare Minerals in Fairly Light, which was extremely matte and a bit cakey, almost CREATING fine lines that I didn't have. (Thinking back, my problems with BE might have been in the application, but I'm off point.) Comparing the two, the Perfect Blemish Balm has really great coverage and a dewy (but not at all oily) finish. Because it's marketed (almost exclusively) to Asian people, it has yellow undertones, though it's pinker than other Korean foundations I've tried. I naturally have pink undertones, so this BB cream wasn't a perfect match for my skin, but after a half hour or so it adjusts slightly to better match my skin tone. Though my skin isn't perfect, this foundation makes my skin look simply flawless - it makes the pores around my nose look smaller, covers up small imperfections, and adds a really beautiful glow to my face. I often get compliments on my skin since I started wearing this BB cream. (My favorite was "Your skin looks like porcelain!") The staying power is quite good, too - I've worn it for 12+ hours without oxidation - it still looked fresh without much difference from moment of application.
For me, the real selling point about BB creams is the healing properties. Since I've started using the BRTC Perfect Blemish Balm (about two months ago), my skin has generally improved: I don't get breakouts anymore, skin tone has evened out, and the pores around my nose have gotten smaller. I've been told that the Perfect Blemish Balm's oil control isn't as good as that of the Perfect Recover Balm, but I didn't really see a difference because my skin isn't all that oily in the first place. Actually, the Perfect Recover Balm dries my face out, but I heard it's better for people with acne or oily skin.
Because I naturally have really pale skin, the shade of the BB cream isn't much of a factor for me, but for my darker-complexioned friends, this BB cream looked really pale (and a bit unnatural) on them. They told me, however, that after an hour or so, it blended more into their skin tone (though not completely). Unfortunately, most BB creams only come in one or two shades - both pale - because BB creams are marketed almost exclusively to East Asian people. If it helps, for reference I wore Fairly Light (1.2) in Bare Minerals, and most BB creams are about as pale as my skin.
Remember that this BB cream IS a cosmetic product - wearing no makeup at all would probably be best, but this is better for skin that other foundations. You have to wash it off! I get really sick of people complaining that BB cream gave them breakouts when they didn't wash it off completely! Unless makeup is washed off completely, it can cause breakouts and wrinkles. I suggest using a cleansing oil, since it's really the only thing that can get the residue off completely. Also remember to wear a primer or sunscreen underneath!
