Who doesn’t love smooth skin? Scrubs can be a great way to exfoliate skin so it feels super soft. Scientific White Bamboo Exfoliator ($68, scientificskin.com) by Kenneth Beer, M.D. is a clay-based scrub, microsifted with white bamboo that promises to purify skin, minimize pores and balance excess oils providing a more luminous, smoother, younger-looking complexion. Scientific sent over a sample for me to try, and I found that the antioxidant-packed scrub made my skin feel supple, though I think the bamboo might be a bit coarse for more sensitive skin.
Acai berry comes from the plant Euterpe oleracea native to Central and South America (Appetite). Acai has recently been in the marketed for weight loss purposes but is found in beverages and food products. Acai seed oils are used in cosmetic products for their beneficial properties.
Acai berries contain antioxidants acting as free radical scavengers. According to the book Natural Products: Essential Resources for Human Survival, acai berry has one of the highest contents of vitamin C in a natural source. A study on their antioxidant potential concluded that acai is effective against superoxide along with peroxyl, peroxynitrite, hydroxyl radicals, the most common type of reactive nitrogen or oxygen species (Journal of Agricultural and Food Chemistry).
Tea seems to be everywhere in cosmetics. The white bamboo exfoliator by scientific contains both green tea and white tea. Different processing methods produce different types of tea. White tea is made from buds and young leaves which are steamed and fired to inactivate polyphenol oxidase in turn giving white tea high concentrations of catechin (Oregon State University). Green tea on the other hand is made from mature leaves and are withered prior to steaming or firing (Oregon State University).
Tea is known for its antioxidant activity. According to Experimental Dermatology, both green and white tea are photoprotective agents. The researchers wanted to see if topical application of green tea or white tea would prevent oxidative damage to volunteers who were given green or white tea topically after UV irradiation. They found that the teas has similar levels of photoprotection.
Green tea is said to have antimicrobial properties by preventing bacterial growth through altering the bacterial membranes to stop it from binding to mammalian cells (Food chemistry). Essentially, green tea is antimicrobial, because it stops bacteria from adhering to cells, which is necessary for bacteria to thrive on its host (Clinical Microbiology Reviews).
Ferulic acid is a phenolic antioxidant found in high concentration in plants. It inhibits UVA and UVB- induced expression of metalloproteinases (MMPs) responsible for degrading collagen (Photochemistry and Photobiology, Journal of Nutrition and Biochemistry). This is done through the proteasome pathway, degrading MMPs before they degrade collagen.
In a study in the Journal of Investigative Dermatology researchers found that ferulic acid improved the stability in a formula of 15% L-ascorbic acid and 1% alpha-tocopherol. It also doubled vitamin C and E’s photoprotection against UV-irradiation in this study, though it's important to note that the forms of vitamin C and E in this scrub are different forms.
I’ve been using Scientific White Bamboo Exfoliator twice a week (which is about how often it should be used), and my skin has been super soft. I felt the exfoliator — microsifted bamboo — was a little rough, so I definitely wouldn’t use this too many times in a week.
The product gives off a nice heat when you use it, and it doesn’t have a scent, which I personally liked. Overall, it left my skin soft and smooth, though I think it’s a bit on the coarse side.
Scientific White Bamboo Exfoliator is a great scrub when you want deep exfoliation. Acai berry is an antioxidant and anti inflammatory scavenging for free radicals and inhibits NF-κB. Green and white tea have similar beneficial properties: They’re both photoprotective agents and antioxidants. Ferulic acid also inhibits UVA and UVB irradiation and doubled the effectiveness of vitamin C and E. However, the bamboo is pretty coarse for exfoliation, so I wouldn’t recommend it to those with sensitive skin.
