Retinol may be the gold standard of skin care, but its nuances—especially in formulation—are often misunderstood. For clarity, Dallas dermatologist Elizabeth Houshmand, MD offers a simple breakdown: “Retinal (retinaldehyde) and retinoic acid (tretinoin) are all types of retinoids. Retinol is the most common over-the-counter form and, as the alcohol form of vitamin A, requires two conversion steps in the skin to become the active form (retinoic acid). Retinal is one step away from conversion to retinoic acid, making it more potent and faster-acting than retinol.” That increased potency can mean quicker results but also a higher risk of irritation, making a low-and-slow approach essential. That’s also where a lot of the confusion around retinol begins.
From how it works to how it’s used, there’s no shortage of misconceptions. Some are rooted in outdated information, while others come down to differences in formulation. Ahead, the biggest retinol myths—debunked by experts.
