B Kamins' signature ingredient is a derivative of sugar maple. Now, its role in skin care is fairly specific. It is a natural alpha hydroxy acid and exfolliant. As a long time rosacea sufferer, I have learned the hard way that peelers and exfolliants can make matters a lot worse. Some rosacea experts would go so far as to say AHAs can cause roscacea.
There is also a Ph balancer in this product called triethanolamine. This can be an irritant and, according to one study, is a possible carcinogen.
The sunscreen ingredient, ethylhexyl methoxycinnamate is a particularly unpleasant one. It can produce excess reactive oxygen species that can interfere with cellular signaling, cause mutations, lead to cell death and may be implicated in cardiovascular disease. Nice. A study published in Contact Dermatology associates it with causing allergic reactions.
