Episode 40: Medicine's Biggest Misses: The Skin Treatments We Got Wrong

Dermatology has come a long way, but not every treatment from the past deserves a comeback. In this episode, Dr. Dustin Portela and PA Austin Lee take a fascinating look at some of the biggest blind spots in skin health and beauty, from mercury and arsenic in cosmetics to x-ray treatments for acne, sun lamps, coal tar therapies, and aggressive phenol peels.

They break down why these treatments were once accepted, what doctors and patients believed at the time, and how better evidence eventually revealed the risks. Along the way, they also touch on acne myths, outdated assumptions about hygiene and diet, the dangers of unregulated skin-lightening creams, and why some modern at-home beauty devices may become the next blind spot we look back on with regret.

But this episode is not just about the past. It is also about how good medicine actually works. Dustin and Austin talk about why evidence-based care matters, how science keeps evolving, and why the best providers stay humble, keep learning, and listen closely to their patients. They also explore how technology, research tools, ingredient transparency, and personalized skincare are helping modern dermatology move in a smarter and safer direction.

If you have ever wondered how medicine changes over time, why old advice falls apart, or what current trends may not age well, this episode is equal parts eye-opening, thoughtful, and incredibly relevant.

Product of the Week: AlphaRet from Skinbetter Science

AlphaRet is one of Dr. Portela and Austin's favorite retinoid products because it combines real results with a level of gentleness that is hard to find. It features retinoic acid along with lactic acid and glycolic acid to improve skin tone, texture, and signs of aging while staying more tolerable than many traditional retinoids.

It is one of the most popular products in their office and a longtime Skinbetter Science standout.
