I see people asking what bb creams are all of the time. So hopefully this is helpful. I’ve been using bb creams exclusively since last year. I’ll never go back to a regular foundation ever again. This is taken from the BB Cream wiki page:
BB cream, also known as Beblesh Balm, is a cosmetic item sold mainly in East and Southeast Asia, although larger beauty brands are increasingly introducing BB creams to Western markets as well. Originally formulated in Germany by dermatologist Dr. Christine Schrammek in the 1950s, the cream was initially used to protect skin after laser procedures and surgery, while also providing light coverage.
Introduced to South Korea and Japan in the 1980s, BB cream has been named “the secret of Korean actresses” and has been heavily endorsed by Korean celebrities, which gained it large exposure in these Asian markets.
BB creams come in a variety of different formulations and qualities mainly perceived as being anti-inflammatory and having a soothing effect. As companies focused initially on the East Asian market, BB creams have a limited number of hues. Due to its “multi-tasking” all-in-one properties — moisturizer, primer, foundation, and sunblock — the cream became a hit in Asia, especially in South Korea, where BB creams make up 13% of the cosmetics market. Moreover, the cream is also used by men in South Korea.
