Some things in life are inevitable — death, taxes, and the fact that your favorite shade of lipstick will eventually be discontinued. Others can sometimes be just as certain, like when the hero ingredient everyone has lauded for years suddenly enters its villain era.
For retinol, it appears that time has come.
Retinol, a potent form of vitamin A, has long been the gold standard for anti-aging skincare routines. Decades of dermatological research confirm that retinol can literally reverse the visible signs of skin aging. Its benefits include minimizing the appearance of fine lines and wrinkles, improving skin tone and texture, clearing acne breakouts, and restoring a healthy radiance to the skin.
So, how did skincare’s golden child end up on the beauty blacklist? The answer is less than surprising.
What’s Causing the Controversy?
Retinol is frequently misunderstood because its early side effects include dryness, irritation, and peeling. These symptoms are often misinterpreted, leading to the belief that retinol causes skin thinning. With barrier repair being one of skincare’s biggest talking points, “harsh” ingredients like retinol began to fall under scrutiny.
Retinol’s tendency to cause temporary skin irritation, peeling, and breakouts makes it an easy target for the clean beauty movement. However, claims of skin thinning and barrier damage are largely unsupported. In truth, retinoids actually increase dermal collagen, which over time can thicken the deeper layers of the skin. And while retinoids do have a reputation for causing skin irritation, these effects are often temporary and can be mitigated with proper care.
Additionally, concerns about retinol’s link to cancer have emerged. The concern largely stems from early studies involving systemic retinoids, especially in lung cancer prevention trials for smokers. Systemic retinoids are a class of oral medications that treat severe dermatological conditions and certain cancers by operating throughout the entire body. Unlike topical retinoids, systemic retinoids are ingested as pills or capsules. They travel through the bloodstream to alter how cells grow, mature, and shed. Research has shown that high doses of oral beta-carotene (a nutrient that helps the body produce vitamin A) in smokers increased the risk of lung cancer for that group.
But here’s the key point: These findings do not apply to topical retinoids. Topical retinoids, which are applied directly to the skin and used in much lower concentrations, are not absorbed systemically. Multiple long-term studies have found no evidence that topical retinoids increase cancer risk.
Finally, in 2024, the European Union (EU) announced new restrictions on retinoid usage. Although not an outright ban, the EU imposed a cap limiting retinoid concentrations to 0.3% for face products and 0.05% for body care. As is often the case, social media influencers and clean beauty advocates seized upon this new information and twisted it, claiming that retinol causes cancer. While dermatologists and other experts swiftly refuted these claims, suspicion and skepticism had already firmly taken root in the public’s opinion.
Is Retinol Safe?
When used correctly, retinol is perfectly safe. But using it too often or at a high strength can result in skin irritation. In addition, using retinol without daily sun protection can increase your risk of sun damage and skin cancer. Side effects are likely to disappear after a few weeks of regular use, so it’s important to give your skin time to adjust. Moreover, it’s important to find the type, formulation, and concentration of retinol that works best for you. Retinol is not a one-size-fits-all ingredient; some individuals with sensitive skin or certain skin conditions may want to avoid it altogether. However, when used properly and with consistent sun protection, retinol can alleviate many skin issues.
Final Thoughts
Regardless of controversy, retinol is widely considered by experts to be a safe and effective ingredient. When choosing a retinol, the formulation’s concentration (strength) and your skin type matter most. It’s essential to strike a balance between the product’s potency and your skin’s tolerance to maximize anti-aging benefits while minimizing the risk of irritation. Always begin with a low concentration and seek out formulas that combine the active retinoid with skin barrier protectors such as ceramides, niacinamide, and hyaluronic acid. Use retinol as part of your nighttime skincare routine, and always remember to apply sunscreen during the day.
