@thetiarawillis The moment you challenge people with arguments like that asking for details and nuances, their entire argument crumbles. Those arguments rely on broad quick statements without the opportunity for detailed review.

@NicHulscher Correlation is not causation.

@Cornfrmr 'I drive a lot. I never wear seatbelts. I haven't gotten into an accident yet. Maybe seatbelts are the problem.' 😑 n=1 reasoning.

@likebattleangel Retinoids remodel collagen over months, not overnight. Glad you stuck with it. Keep daily SPF or a lot of that progress fades in the sun.

@crownluvletter Sunscreen is one of the few real cancer prevention tools you can buy without a prescription. Looking younger happens to be a side effect that some people desire. Nothing wrong with that.

@MrPool_QQ Correlation is not causation. We find more skin cancer because screening got better, people live longer, and intentional tanning exploded. UV damages DNA and its not a conspiracy. Enough of this AI generated conspiracy slop.

@BobbyFreiler antibiotics are made in response to bacterial infections....which are natural. sunscreen was made to prevent skin cancer...also natural

@mind_and_beauty Genetics and age still drive most greying. Stress can play a role in some premature cases, but the copper cannibalism story is oversold. If it were the main cause, every high stress job would turn grey on a schedule. It does not.

@SamaHoole Melanoma rose for many reasons: better detection, aging populations, changing sun habits, and UV exposure. Rising sunscreen sales do not prove sunscreen causes melanoma any more than rising seatbelt use proves seatbelts cause crashes.

[Dr. Danny Guo | Dermatologist @drdannyguo]

@BGatesIsaPyscho Correlation ≠ causation. Skin cancer rose as detection, sun habits, and aging populations changed, not because SPF is carcinogenic. UV is the proven carcinogen. Wear the sunscreen.

No evidence that Ivermectin can cure skin cancer. Even if it smooths out the surface, doesn't mean the roots are gone. Mohs is a great idea.

Hot take: there needs to be more regulation on peptides categorically, like the stuff that people are injecting themselves with at home based on some social media personality's advice. Can't believe its a thing

[Dr. Danny Guo | Dermatologist @drdannyguo]

@nicknorwitz How are we normalizing self injecting unproven medications at home. The study was done in HIV patients who have visceral fat from antiretrovirals, not healthy individuals with abdominal fat.

@beyoumf Hello!

Acne is often treated with trends instead of science. In this video, I explain what actually causes acne including oil production, clogged pores, bacteria, and inflammation, and walk through an evidence based plan to treat breakouts and prevent scars.

Complicated skincare is often filled with trends instead of science. In this video, I break down a simple, evidence-based routine focused on cleansing, 2 serums, moisturizer, and sunscreen. No hacks, just what actually works.
