The face ages differently than any other part of the body. It is the surface most exposed to the environment, the most expressive, the most scrutinized — by others and by ourselves. It is also the most biologically complex in terms of how it changes over time, because facial aging is not simply a skin problem. It is a structural problem: shifting fat compartments, bone resorption, muscle change, and volume redistribution happening beneath the surface, with the skin responding to all of it simultaneously. Understanding what is actually happening — and what the research says about when, why, and how visible aging progresses — changes the way patients think about bothprevention and treatment. At Beverly Hills Center for Plastic & Laser Surgery, Dr. Ben Talei brings a depth of training that is genuinely rare in this field. He completed his residency in Head and Neck Surgery at Columbia University, Cornell University Medical Center, and New York Presbyterian Hospital, where he served as Chief Resident and as a fellow at Memorial Sloan Kettering Cancer Center. He then completed two separate fellowships in Facial Plastic and Reconstructive Surgery — a distinction that places him among only a handful of surgeons in the country to hold dual fellowship training. He is dual board-certified, has pioneered the SMART Lift technique (a modified extended deep plane facelift), and has performed the upper lip lift procedure more than any surgeon in the world. His publications on advanced face and neck lifting techniques are used to train surgeons globally, and visiting surgeons come to Beverly Hills weekly to observe and learn his methods. What follows is what the science of facial skin aging actually shows — and what it means for patients who want to understand their options clearly. Collagen Loss Begins in Your Mid-20s — and Accelerates With Every DecadeMost people assume skin aging is something that becomes relevant in their 40s or 50s. The biology starts earlier. Collagen production in the dermis — the structural protein that gives skin its firmness, elasticity, and resistance to wrinkling — begins declining at a rate of approximately 1% per year starting around age 25. By the time a patient is in their late 30s, measurable collagen reduction has been occurring for over a decade. By the age of 50, the average person has lost roughly 30% of their skin’s collagen density compared to peak levels. After menopause, women experience an accelerated rate of collagen degradation — studies show that women lose approximately 30% of their remaining skin collagen in the first five years following menopause, with the rate then stabilizing at around 2% per year thereafter. This accounts for why facial skin changes can appear to accelerate in midlife: the underlying structural loss that’s been occurring gradually becomes visibly apparent at the surface. Understanding this timeline shifts the conversation from reactive to proactive. The patients who maintain the most natural, long-lasting results are often those who addressed early structural changes before significant volume and elasticity loss had compounded. Sun Exposure Is Responsible for Up to 90% of Visible Facial AgingIntrinsic aging — the biological processes that occur regardless of environmental exposure — accounts for less than the majority of what we see on the face. Photo-aging, the skin changes driven by cumulative ultraviolet radiation exposure, is responsible for an estimated 80 to 90% of visible skin aging, including fine lines, uneven pigmentation, loss of texture, and the breakdown of collagen and elastin in the dermis. For patients in Southern California, this matters in a specific and practical way. The UV index in Los Angeles and Beverly Hills regularly reaches extreme levels from spring through fall, and year-round sun exposure is simply a feature of life in this region. Cumulative UV damage to the facial skin doesn’t announce itself with immediate visible change — it accumulates over years and decades, expressing itself later as the accelerated aging that patients attribute simply to “getting older. ”Photodamage operates through two primary mechanisms: direct DNA damage in skin cells, and the generation of free radicals that degrade collagen and elastin fibers. Unlike intrinsic aging, which follows a relatively predictable biological clock, photo-aging is highly variable between individuals based on sun exposure history, skin type, and protective habits. This variability is exactly why two people of the same age can present with dramatically different degrees of facial skin aging. The Face Loses an Estimated Teaspoon of Fat Per Year After 40The volumetric changes that drive so much of facial aging are not primarily about the skin itself — they are about what lies beneath it. Facial fat is organized into distinct anatomical compartments that descend and redistribute with age. Studies using CT imaging have quantified that the average face loses meaningful fat volume from key compartments — the cheeks, the periorbital area around the eyes, and the temples — beginning in the 40s and continuing progressively thereafter. One frequently cited model estimates a loss of approximately one teaspoon (5mL) of facial fat volume per year after the age of 40 across all compartments combined. The practical effect is hollowing in the temples and cheeks, deepening of the nasolabial folds, descent of the midface, and increased skeletal visibility. At the same time, fat may accumulate in the lower face and jowl area, creating the heaviness in the lower third that patients often describe as “sagging. ”This is why surgical approaches that address only the skin — tightening and pulling without repositioning underlying structure — produce results that look operated on rather than naturally rejuvenated. The deep plane facelift, which Dr. Talei has pioneered and refined through his SMART Lift technique, works beneath the skin’s surface to reposition the SMAS layer and underlying fat compartments to their anatomically appropriate positions. The result is a restoration of volume and contour rather than a stretched appearance. It is also why his results are known for their longevity — repositioned structure stays repositioned in a way that surface tightening cannot replicate. Facial Skin Is 40% Thinner Than Body Skin — and Gets Thinner With AgeFacial skin is structurally distinct from the skin covering the rest of the body. The average skin thickness on the face ranges from approximately 0. 5mm at the eyelids — among the thinnest skin anywhere on the body — to about 2mm at the cheeks and forehead. Body skin averages 2 to 4mm in most regions. This thinness is part of what makes the face so expressive and capable of the fine muscular movement that communicates emotion. It also makes facial skin significantly more vulnerable to environmental damage, less capable of sustaining moisture, and more susceptible to the visible effects of volume loss beneath it. When subcutaneous fat diminishes with age, thin facial skin drapes over the resulting contour changes much more visibly than thicker body skin would. The dermis — the deeper structural layer — also thins with age. Research indicates that dermal thickness decreases by approximately 6% per decade. Alongside this thinning comes a reduction in the density of hyaluronic acid, the naturally occurring substance that keeps skin plump and hydrated by attracting and retaining moisture in the tissue. These changes compound: thinner dermis with less hyaluronic acid means skin that is both structurally weaker and less hydrated, creating the combination of fine lines, roughness, and loss of plumpness that characterizes aged facial skin. The Relationship Between Internal Health and Facial Appearance Is MeasurableThe skin is the body’s largest organ and a visible reflection of what is happening systemically. Research published in major dermatological and medical journals has consistently documented measurable relationships between lifestyle factors and facial skin age as assessed by blinded evaluators. Chronic sleep deprivation — defined as fewer than six hours per night for extended periods — produces measurable increases in perceived facial age, including puffiness, sagging, and uneven pigmentation. Smoking accelerates facial aging at a rate estimated to produce visible skin changes equivalent to adding 1. 4 years of aging for every decade of smoking. Chronic psychological stress elevates cortisol levels, which directly suppresses collagen synthesis and increases MMP (matrix metalloproteinase) activity — the enzymes responsible for breaking down collagen. Conversely, patients whose systemic health is well-maintained — consistent sleep, controlled stress, protection from UV exposure, and appropriate nutrition — present with measurably better baseline skin quality before any interventional treatment. This matters for surgical outcomes. Dr. Talei’s philosophy is grounded in the same principle that defines his approach to every consultation: achieving the most natural, long-lasting results requires understanding the whole patient, not just the specific area to be treated. The Consultation That Changes the ConversationUnderstanding the science of facial aging — the timeline, the mechanisms, the structural and surface changes — is the foundation of having a genuinely productive consultation about what is possible and what makes sense for your specific situation. At Beverly Hills Center, we invite patients to come in for a conversation. Dr. Talei is known for his candor: he will tell you what he believes will serve you well and what he doesn’t think will produce the results you’re looking for. That honesty, backed by a level of facial plastic surgery training that is among the most distinguished available anywhere in the country, is what has made the practice a destination for patients from Beverly Hills, Los Angeles, Santa Monica, and around the world.
