In October, 2014, Allure Magazine posted on its website an article titled “The 11 Biggest Retinoid Myths” that seeks to correct the false information surrounding retinoid products. The article first draws the distinction between retinoic acid and retinol. The former is the ingredient that actively combats visible aging and is only available by prescription. Retinol, available in over-the-counter products, first needs to be converted by the skin at the cellular level into retinoic acid before it can be effective. One common myth about retinoids is that they work by exfoliating the skin when in fact redness and peeling are just a side effects. Retinoids actually work at a cellular level by affecting gene expression, smoothing skin, enhancing collagen production, and evening out pigmentation.
