You’ve probably got a tube of Retin-A or some generic tretinoin sitting in your bathroom cabinet right now. It’s the "gold standard" for acne and wrinkles, the one thing dermatologists actually agree on. But if you look at the fine print of where that discovery came from, things get dark fast. We’re talking about the Dr Kligman case study, a decades-long saga at Philadelphia’s Holmesburg Prison that honestly reads more like a horror movie than a medical breakthrough.
Dr. Albert Kligman was a giant in his field. He was brilliant, charismatic, and basically the father of modern cosmeceuticals. But he also looked at a room full of incarcerated men and saw what he called "acres of skin." Not people. Just surface area for testing.
The Reality of the Dr Kligman Case Study
For about 24 years, from 1951 to 1974, Holmesburg Prison wasn't just a place for detention; it was a massive, unregulated laboratory. Kligman wasn't just doing little "dab of cream" tests, either. He was running trials for the U.S. Army, the CIA, and giant pharmaceutical companies like Johnson & Johnson and Dow Chemical.
The variety of what they did is staggering.

- Pathogen Inoculation: They intentionally infected inmates with herpes simplex, staphylococcus, and various fungi.
- Chemical Warfare: Dow Chemical paid Kligman to test dioxin—the toxic ingredient in Agent Orange. He used doses hundreds of times higher than what the protocol called for.
- Skin Torture: They used acids that literally corroded skin to a leather-like texture. They even performed "anesthesia-free" surgeries to remove sweat glands for examination.
Kinda makes that nightly skincare routine feel a bit different, doesn't it?
Why the Inmates Said Yes
People always ask why anyone would agree to this. Honestly, it’s simple: money. In a place where a "good" job sweeping floors paid maybe 25 cents a day, Kligman was offering a dollar or two. To someone who’s broke and needs to buy soap or cigarettes from the commissary—or save up for bail—that’s a fortune.
It wasn't really "informed consent." It was "coerced survival." Most of these men, the majority of whom were Black, had no idea they were being injected with radioactive isotopes or carcinogens. They thought they were testing hair dye or skin moisturizer.

The Retin-A Connection
This is the part that hits home for most of us. Tretinoin (Retin-A) was essentially perfected at Holmesburg. Kligman used the inmates to find the right concentrations to treat acne without causing total skin failure. While he made millions in royalties and became a hero in the dermatology world, the men who actually "gave" their skin for the research got nothing but scars.
Actually, it's worse than that. Many survivors reported lifelong psychiatric issues, chronic rashes, and physical disfigurement. One survivor, Herbert Rice, talked about how he was given "foreign organisms" in pills that caused him to hallucinate so badly he ended up in solitary confinement.
The University of Pennsylvania eventually apologized in 2021. The City of Philadelphia followed suit in 2022. But apologies don't fix the fact that for twenty years, the medical establishment viewed these men as "cheaper than chimpanzees."

The Legacy We Live With
The Dr Kligman case study is the main reason we have such strict rules about experimenting on prisoners today. It led directly to the Belmont Report and federal regulations that treat prisoners as a "vulnerable population." It’s a messy legacy. On one hand, we have life-changing medications. On the other, we have a history built on the systematic exploitation of people who couldn't say no.
If you're looking for the "truth" behind your skincare, this is it. It’s not just science; it’s history, and it’s often ugly.
What you can do next:
- Educate yourself on medical ethics: Read Acres of Skin by Allen Hornblum. It’s the definitive account of what happened at Holmesburg.
- Support equitable research: Look into organizations like the Skin of Color Society which works to ensure dermatological research is inclusive and ethical.
- Check your brands: While most modern testing is strictly regulated, supporting companies that prioritize transparent and ethical sourcing is a small way to vote with your wallet.
