Skin Side Out Episode 70 explores the connection between skin health, metabolism, aging, and longevity. Dr. Zain, Heather, and Courtney discuss how dermatology is moving toward a more comprehensive approach that considers what is happening inside the body, not just what appears on the skin.

The conversation covers regenerative medicine, collagen, GLP 1 medications, muscle loss, metabolic health, inflammation, lab testing, and how changes in the body can show up through the skin. They also discuss the importance of working with a primary care physician, being cautious with emerging treatments such as peptides and exosomes, and understanding the difference between promising treatments and those backed by strong evidence.

The episode wraps up with five pillars of healthy aging: sun protection, preserving muscle and bone, optimizing metabolic health, reducing inflammation and environmental damage, and using aesthetic treatments thoughtfully. They also emphasize sleep, mental health, healthy routines, and focusing on becoming the best version of yourself rather than trying to look like someone else.

Dr. Zain Husain hosts Heather and Courtney on Skin Side Out to discuss ideal fall and winter cosmetic treatments, focusing on pigment, vascular concerns, and anti-aging. They review options for pigment including IPL (with cautions for melasma and tanned skin), pigment-specific lasers, medium-depth TCA-based chemical peels like the Perfect Derma Peel, and non-ablative fractional lasers. For vascular issues such as redness and rosacea, they cover IPL, hemoglobin-targeting vascular lasers, a low-downtime laser facial using 1064/532, pulsed dye laser (PDL), and electrocautery for cherry angiomas. Anti-aging topics include microneedling and RF, non-invasive energy devices, non-ablative and ablative lasers (CO2 vs erbium), injectable biostimulators (Sculptra, Radiesse), neurotoxin, peels, hyaluronic acid fillers, PRP/PRFM, and hair restoration, plus laser hair removal as a good fall option.

Optimizing Fall Skin Treatments: Retinoids, Brightening Agents, Rosacea Care & Collagen Boosters | Skinside Out

Dr. Zain hosts Skinside Out with Heather and Courtney to discuss optimizing skincare and pre-treatments for fall procedures as weather shifts cooler and drier. They recommend a solid baseline regimen (vitamin C, retinoids, sunscreen) and adjuncts like growth factors, exosomes, and peptides to support recovery and collagen. For pigment concerns after summer sun, they cover hydroquinone (with breaks and dermatologist guidance), tranexamic acid, arbutin, kojic acid, azelaic acid, glycolic acid, and retinoids, plus options like oral tranexamic acid, glutathione, and antioxidant supplements including Inner Glow Age Defense with polypodium leucotomos. Sunscreen is emphasized, including Isdin Eryfotona Actinica. For redness/rosacea, they review sulfur products, ivermectin, azelaic acid, metronidazole, Rhofade for events, lasers (IPL, DermaV), and doxycycline. For texture and laxity, they highlight growth factor serums, ReQ, Plated, and exosomes, and discuss gentle peels (mandelic, glycolic) and PRX peel as low-downtime collagen stimulators, with guidance on pausing actives around procedures.

In this “Rate the Rave” episode of Skinside Out, Dr. Zain Hussain with Heather and Courtney score trendy skincare products from 1–10 and explain why. They rate snail mucin low as a nonessential hydrator, pimple patches as helpful mainly for preventing picking (with irritation risks from added actives), and Differin Gel as an accessible, tolerable starter acne treatment for teens. Medicube Pink PDRN Serum scores near zero due to concerns about buzzword marketing and unclear sourcing/amounts of PDRN. St. Ives Apricot Scrub is strongly discouraged for irritation and barrier damage. Hypochlorous spray rates high for gentle antimicrobial/anti-inflammatory use, while opinions vary on The Ordinary and SkinCeuticals C E Ferulic (cost, smell, irritation, oxidation). La Mer is rated low due to price, TNS Advanced Serum is moderately recommended, CeraVe Hydrating Cleanser is disliked, Vanicream is highly favored for gentleness, beef tallow is rejected, nose strips are rated poorly, slugging gets mixed reviews, and sunscreen is rated 10/10 with favorite picks shared.

Dr. Zain hosts Skinside Out with Heather and Courtney to share a back-to-school skincare survival guide for high school and college students. They emphasize keeping routines simple and realistic, avoiding starting many new products at once, and sticking to morning basics: gentle cleanser, moisturizer, and sunscreen. They discuss the importance of not sleeping in makeup, keeping hands off the face and not picking pimples, and showering or cleansing after heavy sweating to help prevent acne and folliculitis without over-scrubbing. They recommend cleaning items that touch the face (phones, headphones, helmets, computers) and not ignoring body skin issues like eczema, folliculitis, and tinea versicolor. They note stress can affect skin and suggest stress management strategies, ending with quick rules including sunscreen daily and that consistency beats complexity.

In this episode of Skinside Out, Dr. Zain Husain, Heather Murray, PA-C, and Courtney Carroll, LE, break down practical skincare tips for nearly every kind of trip, from beach vacations and mountain hikes to snowy destinations, city trips, and humid tropical environments. 

They cover sunscreen application and reapplication, sun-protective clothing, forgotten areas like the lips and tops of the feet, dry skin at altitude, bug protection, travel-sized skincare, hotel products, acne while traveling, and what essentials are worth keeping in your bag.

You’ll also hear why a “base tan” is really just sun damage, why snow can increase UV exposure, why you may want to bring your own cleanser and moisturizer, and why tweezers might be one of the most underrated items in your travel kit.

Whether you’re heading to the beach, the mountains, a city, or somewhere tropical, the goal is simple: prepare your skin for the environment before you get there.

In this episode of Skinside Out, Dr. Zain Husain, Heather, and Courtney break down the most common summer skin problems they see in the dermatology office, including poison ivy, contact dermatitis, phytophotodermatitis, folliculitis, sunburns, fungal infections, bug bites, tick bites, heat rash, and swimmer’s itch. 

They explain what these conditions can look like, what causes them, how they’re commonly treated, and when a rash or bite deserves professional attention.

You’ll also hear why limes and sunlight can cause a surprising skin reaction, why sitting in a wet bathing suit can lead to trouble, what a bull’s-eye rash may mean after a tick bite, and why not every suspected spider bite is actually a spider bite.

The goal isn’t to keep you indoors—it’s to help you enjoy summer while protecting your skin.

The team discusses collagen loss, thinning skin, rosacea, hormonal acne, hair thinning, dryness, pigmentation, enlarged pores, neck aging, and how declining estrogen impacts skin health. They also explain evidence-based skincare routines, hormone replacement therapy, topical estradiol, retinoids, chemical peels, microneedling, lasers, facials, growth factors, and lifestyle changes that can help you age confidently.

For many people, this is the decade when fine lines, collagen loss, pigmentation, adult acne, and early volume changes become noticeable. The good news? It's also the ideal time to prevent many of the signs of aging before they become much harder—and more expensive—to treat.

The team discusses collagen production, retinoids, vitamin C, sunscreen, Botox, fillers, Sculptra, microneedling, IPL, chemical peels, hormonal acne, GLP-1-related facial volume loss, and simple lifestyle changes that can help you maintain healthier skin for decades to come.

Whether you're just entering your 30s or already there, this episode provides practical, dermatologist-backed advice on building a skincare routine that works today while protecting your skin for the future.
