Episode: The Gift of Real Talk: Is Vitamin C Overrated? "Anec-data" and the Truth About $400 Luxury Serums With Dermatologist Dr. Aegean Chan
Date: December 24, 2025
Hosts: Jill Dunn and Carlene Higgins
Guest: Dr. Aegean Chan, Double Board-Certified Dermatologist and Dermatopathologist

Overview

In this refreshingly candid episode, Jill and Carlene are joined by Dr. Aegean Chan—a leading dermatologist and dermatopathologist—for a deep dive into skincare “real talk.” They explore trending topics like the skin barrier, vitamin C's status in skincare, "anec-data," luxury serums, transdermal patches, and the truth about in-office treatments. Dr. Chan brings an expert, evidence-based approach that challenges hype and focuses on what actually works, all served with relatable, unfiltered honesty.

Key Discussion Points & Insights

1. Dr. Chan’s Unique Perspective as a Dermatopathologist

• Role Defined: Dr. Chan explains dermatopathology as the bridge between lab analysis and clinical dermatology. When a dermatologist biopsies a skin issue, Dr. Chan is often the one examining it under the microscope to diagnose, for example, cancerous cells or rashes. (04:47)
• Quote: “When you’re thinking about products and thinking about claims, I always have that image in my mind: could this cream actually alter this chronic change from UV damage over 50 years?” — Dr. Chan (07:27)

2. The #1 Skin Aging Culprit: UV Damage

• Insight: There’s “no big secret”: UV exposure is still the single biggest driver of skin aging, dramatically degrading collagen and elastin, as seen under a microscope. (06:16)
• Prevention over reversal: Prevention is more effective than reversal, and most skincare “miracles” can’t undo years of sun damage. (07:45)

3. Skin Barrier: The Underrated Foundation

• Science Lesson: The skin barrier is a complex, dynamic organ, not “just a kitchen counter you need to scrub clean” (08:58). It consists of stacked dead skin cells with a lipid bilayer and proteins working together.
• Advice: Give your skin credit—it’s evolved over millennia to protect you. Focusing on barrier health supports all other treatments. (09:54)
• Quote: “If you want to maximize medication, you want a healthy skin barrier first.” — Dr. Chan (10:42)
• Routine Reset: With acne or irritation, Dr. Chan often tells patients to stop all actives, just do gentle care for a week, and notes that “a lot of times, that gets rid of a lot of their acne.” (11:18)

4. PH Obsession: Are We Overdoing It?

• Perspective: PH matters, but “I do think it’s become something that people become overly concerned about.” Well-formulated products account for PH, except notably for vitamin C (especially ascorbic acid), which can be problematic for some. (12:20)

5. Vitamin C: “Overrated” Status Explored

• Dr. Chan’s Hot Take: “I honestly think it’s overrated... For me, vitamin C is sort of a second tier.” — Dr. Chan (14:05)
• Routine Recommendations: Prioritize cleanser, moisturizer, sunscreen. Add a retinoid. If all is well, consider AHA (like lactic/glycolic acid) before vitamin C. “I think vitamin C is overhyped while the old school, proven ingredients get neglected.” (15:12)
• Personal Choice: Dr. Chan and the hosts do not use vitamin C regularly, as they don’t see immediate benefits. If you try a bottle and see no results, “that’s information. That’s okay.” (16:45)

Notable Quotes

• On Vitamin C (14:05):
  “I honestly think it’s overrated... Focus on your skin barrier.”
• On Trying Products (16:45):
  “Try one bottle. If you notice no difference, put your effort elsewhere.”

6. Microbiome—What Do We Really Know?

• Microbiome is important but scientific understanding isn’t robust yet. Most microbiome marketing is “hard to say whether those things are musts.” Stick to basics, but “anec-data” (anecdotes treated as data) dominates places like TikTok; it’s not strong evidence. (20:14)
• Defining Anec-data:
  “It’s really when people use anecdotes as data – which I think is like all of TikTok.” — Dr. Chan (21:09)

7. Do Topicals Absorb? Navigating Confusion

• Penetration Depends: Whether an ingredient penetrates the skin varies widely by molecule. Most topicals don’t enter the bloodstream, but some proven exceptions (like sunscreen filters) exist. (23:54)
• Pregnancy vs. Breastfeeding: Dr. Chan busts myths, especially around retinoids during breastfeeding—trace amounts don’t harm infants (per data), but caution is warranted in pregnancy due to effects on fetal development. (25:29)

8. Sun Protection: Don’t Just Rely on SPF

• Takeaway: Use sunscreen as a last line of defense—sun-safe habits (avoiding midday sun, hats, shade) are even more effective and reliable. (27:26)
• Brands Dr. Chan Likes:
  • Korean sunscreens: Beauty of Joseon Aqua Relief (favorite), although not as much the US version (29:15)
  • EltaMD UV Clear (trusted finish) (29:47)
  • Drugstore gems: Aveeno, Neutrogena (30:31), Trader Joe’s Daily Facial Sunscreen as a Supergoop dupe (30:46)

9. Treating Skin of Color: Gaps & Improvements

• Education Matters: Diagnosis and treatment are complicated by lack of diversity in clinical training—diseases can look completely different on different skin tones.
• Progress: Textbooks are now diversifying images to address this (34:04).
• Quote: “One diagnosis can look 20 different ways... You may not feel as comfortable treating [certain conditions] if you didn’t train with skin of color.” — Dr. Chan

10. In-Office Treatments: Morpheus8 and the FDA Warning

• Perspective: Devices like Morpheus8 (radiofrequency/microneedling) aren’t inherently dangerous, but “operator error” at less-qualified clinics/spas is the bigger risk. Board certified dermatologists are best equipped for safe, effective use. (36:09)

11. Transdermal Patches & Skin Tech

• Potential: Excited about new delivery systems, but efficacy is molecule-dependent and must be proven—ideal would be head-to-head studies versus topical standards like retinoids. (37:44)
• Skeptical on Claims: Patches and cosmeceuticals that “skirt” drug vs. cosmetic regulations require strong evidence. (39:43)

12. Microneedling & At-home Devices

• Enhanced Penetration: In-office microneedling goes much deeper (to the point of drawing blood), and can enhance delivery of actives; at-home devices are less intense. Listen to your skin—if you have excessive irritation, it’s too much. (41:13)

Memorable Moments & Rapid Fire “De-Influence Me: Derm Edition” (42:33)

• Most Universally Unnecessary Product:
  • “First thought was vitamin C; second was sheet masks.” — Dr. Chan (42:47)
• $400 Serums—Worth It?
  • “Save your money and go get Botox.” — Dr. Chan (43:06)
• Eye Creams:
  • “For the average person, your facial moisturizer works around the eyes too.” (43:18)
• At-home Red Light Devices:
  • “It’s really time consuming. You have to be consistent. I know very few patients long-term consistent with red light.” (43:45)
• Most Overrated Skincare Ingredient:
  • “Can I say vitamin C again?” — Dr. Chan (44:20)
• Antioxidants:
  • “Vitamin C is a very good antioxidant... but it’s not miraculous.” (44:39)
