Peter Attia MD355 – Skincare strategies, the science of facial aging, and cosmetic-intervention guidance
CHAPTERS
- 0:00 – 9:22
Introduction and guest backgrounds
Peter Attia frames the episode as a topic where he knows little and describes his own lax skincare habits. Tanuj Nakra (oculofacial plastic surgeon) and Suzan Obagi (dermatologist with a cosmetic surgery fellowship) describe their training and academic practices.
- •Nakra trained in ophthalmology, then oculoplastic and facial cosmetic surgery fellowships
- •Obagi is a dermatologist at the University of Pittsburgh focused on skin rejuvenation and fat grafting
- •Peter notes he looks worse at 52 than at 42 and admits he doesn't wash his face at night
- •Scope is limited to the neck up
- 9:22 – 15:27
Biology of the aging face: fat, bone, and ligaments
Obagi explains that facial fat compartments atrophy and bone recedes with age, producing a tired look that starts around the eyes. She says these changes are largely hormonal and hit women harder after about fifty. Nakra adds the role of retaining ligaments in creating deep lines.
- •About eleven facial fat compartments per side atrophy by the late sixties
- •Bone loss widens the eye openings and narrows the cheekbones and jaw
- •Obagi describes hormone-driven changes, with women aging about 20 years faster than men in the lower face from 50 to 70
- •Nakra cites CT-based studies and the ligament network that tugs on skin as volume is lost
- •Obagi says women should be caught before far into menopause for a hormone replacement discussion
- 15:27 – 24:51
Why facial fat atrophies while body fat accumulates, and the role of stress
Peter asks why he gains body fat while losing facial fat. Obagi describes pregnancy and yo-yo weight changes affecting the face, and both guests say the biochemical mechanism is not fully known. Nakra links cumulative stress and cortisol to faster facial aging and criticizes the poor, commercially influenced science in aesthetics.
- •Facial fat differs metabolically from abdominal and limb fat, including beta-carotene content
- •Grafted abdominal fat retains its source behavior and can hypertrophy with weight gain
- •Nakra suggests chronic stress accelerates facial volume loss and skin aging
- •Two patients of similar age illustrate lifestyle effects on appearance
- •Industry funding makes aesthetic science murky
- 24:51 – 37:20
Evolutionary biology of beauty
Peter asks whether evolution explains the facial changes, and Nakra describes the genetic basis of beauty perception, citing infant preferential-looking studies. The guests discuss symmetry, proportion, and sexual dimorphism as universal features, and how modern diet, jaw development, and exposure to global faces complicate this.
- •Newborns preferentially look at beautiful faces
- •Three universal beauty features: symmetry, averageness/proportion, and sexual dimorphism
- •Obagi says softer modern diets and mouth breathing have changed jaw and palate structure
- •Social media expands the apparent pool of faces far beyond evolutionary norms
- •Appearance was evolutionarily important only until about 20 to 25, so aesthetic work fights biology
- 37:20 – 43:09
Social media, influencers, and shifting beauty trends
Peter asks how trends have changed what patients request over the years. Obagi and Nakra describe influencer-driven trends, filtered and posed images, and exaggerated features such as oversized lips and wider eyes, and say they steer patients toward natural results.
- •Obagi contrasts the pre-social-media era with today's influencer culture
- •Trends are temporary, and patients lack celebrities' resources to reverse them
- •Nakra describes subconscious posing and filtered images that exaggerate symmetry and proportion
- •Exaggerated dimorphic features like big lips are being normalized
- •They decline requests that would distort a patient's face
- 43:09 – 53:52
Ethics, financial incentives, and regulation in aesthetic medicine
Peter asks how widespread unethical practice is. Obagi believes most physicians are ethical but some mass-treat patients, while Nakra says the situation is worse because of financial incentives and weak regulation. They discuss who performs injectables, falling reimbursements, and the artistic motivations of trainees.
- •Obagi compares patient-directed transformations to letting patients set their own insulin doses
- •Nakra warns that providers range from hairdressers to surgeons with financial incentives to treat
- •Obagi says unqualified providers in poorly regulated states create risk of complications
- •Both say declining reimbursement and high cash pay can distort ethics unconsciously
- •Self-pay practices give them time with patients
- 53:52 – 1:00:52
Teenagers and the most concerning cosmetic requests
Peter asks about the most concerning social-media-driven requests. Obagi describes teenagers seeking Botox and fillers, Nakra describes overfilling and the claim that filler lasts only a year, and they discuss consent age and 'beauty pressure'.
- •Teens are being told preventive Botox at 18 is fine, which Obagi calls untrue
- •Selfie distortion makes patients unhappy with how they really look
- •Nakra says overfilling is an epidemic and filler can persist eight to ten years
- •Nobody can predict who metabolizes hyaluronic acid quickly
- •The 'snatched' high-arched brow request and an 18-year-old patient without a parent illustrate the concerns
- 1:00:52 – 1:12:57
UV damage and sunscreen
Starting from prevention, Obagi calls sunscreen the minimum daily step and argues for mineral over chemical sunscreens. The guests explain how UVA, UVB, and other light damage DNA, collagen, and elastin, and how melanin protects darker skin.
- •A randomized Australian study showed sunscreen users aged better
- •Obagi prefers mineral sunscreens due to concerns about chemical filters and says chemical ones degrade within about an hour
- •Obagi says UVA ages, UVB burns, and visible and infrared light also contribute
- •Nakra explains UV injures collagen and elastin and thins skin
- •Melanin acts as a parasol over the cell nucleus; tanning is melanin upregulation
- 1:12:57 – 1:23:30
Retinoids and vitamin C
Obagi recommends retinoids as the next step, explaining retinol, retinaldehyde, and retinoic acid and how to build tolerance. Nakra adds a protocol for sensitive users and explains why vitamin C serums are hard to formulate and why they matter.
- •Retinoids boost collagen, normalize melanocytes, and aid repair; collagen production peaks around 18
- •Obagi advises acclimating to retinoic acid; alternatively 5 days retinaldehyde and 2 days retinoic acid
- •Nakra suggests gradual ramp-up or mixing with 1% hydrocortisone
- •Cheap vitamin C degrades, so stabilized formulations are worth paying for
- •Vitamin C supports collagen synthesis, acts as an antioxidant, and evens skin tone
- 1:23:30 – 1:37:07
Daily skincare routine: cleansing, serums, and moisturizing
The guests walk Peter through application amounts and order, gentle glycerin-based cleansing, antioxidant serums, and moisturizer. They give brand examples and settle on a simple morning and evening routine for him.
- •Use a fingertip unit of retinoid, including under the eyes, applied thinnest to thickest
- •Use a gentle glycerin-based cleanser rather than body soap on the face
- •Antioxidant serum goes on morning and night; retinoic acid only at night
- •Cheap occlusive moisturizer like Aquaphor can improve skin in 30 days; Obagi would add moisturizer later for Peter
- •Peter's plan: cleanser, serum, sunscreen in the morning; cleanser, serum, retinoic acid at night
- 1:37:07 – 1:46:07
Managing acne and Accutane
Peter asks about the playbook for acne. Obagi stresses treating before scarring, describes acne types, and explains when she moves to Accutane or photodynamic therapy, including side effects and monitoring.
- •Cystic acne is treated as a medical emergency because it scars even without picking
- •About 20% of adolescents develop cystic acne, per Obagi
- •Obagi prefers Accutane or photodynamic therapy over long-term antibiotics
- •Accutane risks include dryness, lipid and liver changes, and teratogenicity
- •About 85% need only one five-month course
- 1:46:07 – 2:01:21
Aesthetic consultations and the five Rs of rejuvenation
Peter asks what changed in his face compared to ten years ago. Nakra describes the skin, volume, gravitational, and bone changes, his rapid anatomical assessment, and detective work on patient psychology and readiness. Obagi outlines her five Rs: relax, refill, resurface, redrape, renew.
- •Nakra assesses skin, bone, proportion, volume, muscle movement, and asymmetry in the first seconds
- •Consultations probe motivation and mental state, sometimes starting with reversible treatments
- •Nakra educates patients with a mirror, then gives his opinion at the end
- •Obagi: relax muscles, refill volume, resurface skin, redrape, and renew
- •Cookie-cutter approaches like Botox for every forehead are criticized
- 2:01:21 – 2:25:29
Case study of Peter's face: fat grafting vs fillers and the eye area
Obagi and Nakra analyze Peter's face, covering forehead movement, hollow lid-cheek junction, platysma banding, and asymmetries. They compare fat grafting to fillers on cost and technique and explain why the eye area drives patient motivation.
- •Peter's forehead use partly compensates for upper lid hooding; blanket Botox would feel heavy
- •Obagi compares fat graft cost (about $5,000) to filler syringes ($800–$1,000)
- •Fat grafting uses stem cells, PRP, and nano fat; harvest of about 120 cc is described
- •Nakra cites self-discrepancy theory and the unflattering photo effect as drivers
- •Nakra describes four causes of dark circles and asymmetry that Peter was unaware of
- 2:25:29 – 2:40:11
Eyelid surgery options, brow interactions, and risks of complications
Nakra explains that Peter's upper lids might qualify for insurance coverage, and that eyelid surgery interacts with the brow. He describes transposition lower blepharoplasty and tetracycline for malar mounds, then the guests discuss filler embolism and why bad outcomes occur.
- •Upper blepharoplasty may require Botox or a brow lift to avoid creating new problems
- •Peter would likely be undertreated to avoid disrupting forehead muscle compensation
- •Transposition lower blepharoplasty moves fat to the cheek rather than removing tissue
- •Obagi warns of vision loss and stroke from filler embolism
- •Nakra says bad outcomes are most often the wrong procedure or technical error
- 2:40:11 – 2:51:31
How to choose a cosmetic surgeon
Asked to act as an advocate for a friend, the guests list what to look for in a practitioner: rapport, a comprehensive evaluation, relevant training and board certification, experience volume, and specialization. They also discuss academic involvement and how universities handle aesthetic practices.
- •Obagi advises asking about complication rates, re-treatment rates, and showing varied before-and-afters
- •Nakra cites board certification and at least 25 facelifts or rhinoplasties a year
- •Facial cosmetic surgery is a different specialty than body procedures
- •Choose someone evolving with the field, such as through lecturing and publishing
- •Nakra says patients should research society websites and learn their own anatomy
- 2:51:31 – 3:10:33
Skin resurfacing: ablative vs non-ablative treatments
The guests explain how controlled skin injury triggers healing, and distinguish non-ablative treatments from ablative lasers and peels, including downtime trade-offs. They discuss choosing among options for skin tone and goals, and close with reflections on why people want appearance to match self-image.
- •Greater aggressiveness gives better results but more downtime
- •Non-ablative options include light peels, fractional lasers, vascular lasers, and IPL/BBL
- •Obagi cautions under-45s against ultrasound or radiofrequency tightening due to fat atrophy
- •Ablative lasers can be riskier in darker skin; deeper peels and CO2 lasers have longer recovery
- •Nakra closes on self-discrepancy and why appearance matters at all ages
