Anti-Aging: Rethinking the Promise to Focus Only on What Works
Dr. Anais BambiliFew words in the cosmetics industry hold as much promise as “anti-aging.” The term suggests a battle, a struggle, almost a possible victory over the passage of time. Ever since this category came into existence, it has been built on this tension: the more spectacular the promise, the more legitimate the product seems.
Except that the skin doesn't work through spectacular victories. It ages through a gradual, measurable process that has been extensively documented by dermatology—and this process has very little to do with what the packaging claims.
What “anti-aging” has long meant
The terminology of “fighting wrinkles” or “repairing” stems more from advertising logic than from biological logic: we don’t “repair” aging skin—we support it. Aging skin is not defective skin that needs urgent correction—it is skin whose certain functions are gradually slowing down, and which can be supported more or less effectively depending on the daily habits adopted over time.
At what age do the first signs of aging appear?
The production of collagen—the protein that gives the skin its firmness—begins to decline gradually starting in one’s early twenties, at a relatively slow and steady rate. The first visible signs—a complexion that may lack radiance, a slightly less even texture, and very fine lines around the eyes—may appear as early as one’s mid-twenties in some people, and much later in others. Genetics plays a real role, but according to dermatological literature, cumulative sun exposure remains the most significant environmental factor in the visible signs of skin aging.
The moment you start paying attention to it matters less than how consistently you then stick to a few simple habits.
What Really Accelerates Skin Aging
Two mechanisms overlap in the aging of the skin. The first is intrinsic: the natural slowing of cell turnover and the production of collagen and elastin by fibroblasts, a genetically programmed process common to everyone. The second is extrinsic, and it is the one we can actually control: exposure to ultraviolet rays, pollution, smoking, and glycation—a process by which excess sugar in the body stiffens collagen fibers and accelerates their breakdown. The first cannot be “fought”: it proceeds at its own pace, which is the same for everyone. The second is directly influenced by daily habits.
Actions That Really Make a Difference
If we set aside the marketing jargon, there remains a limited number of practices whose effects on visible skin aging have been consistently documented. Daily sun protection tops the list: when applied every morning—even on cloudy days—it limits the breakdown of existing collagen far more effectively than any corrective active ingredient applied at night. Next is maintaining an intact skin barrier, which retains moisture better, is less prone to irritation, and absorbs applied active ingredients more effectively. Finally, consistency matters more than intensity: a moisturizing and protective routine repeated every day for several years has a cumulative effect on skin firmness and texture that a one-time treatment used irregularly will never replicate.

Understanding this mechanism changes the way we evaluate a product that claims to be “anti-aging”: the question is no longer “what does it promise,” but “what does it actually do, and what specific mechanism does it target”—a question we ask ourselves regularly as we observe this cycle of trends, from bakuchiol to active ingredients touted as miraculous. Consistency, however, cannot be bought: it must be practiced, day after day.
