Acne isn't something you should live with ❌
We can fix it nearly 100% of the time with:

- Lifestyle
- Over the counter products
- Prescription creams
- Prescription tablets
- Procedures

I'll explain it all in this thread, so bookmark and work through these until you're clear! LIFESTYLE:

❌ Avoid whey protein, concentrated sugars and skimmed milk. These make acne flares worse.

❌ Minimize stress (easier said than done, I know). Travel is also a stressor.

✅ Focus on sleeping well (regulates stress) and eating a balanced diet high in antioxidants.

If you heard the latest @theallinpod and the sunscreen safety topic @friedberg raised surprised you, let me add some details as a dermatologist.

I'll explain the 2 types of sunscreen, their safety profiles, and also answer @chamath's Q ("do brown guys need sunscreen?") 👇🏼1/ There are 2 main classes of sunscreen - physical & chemical. Physical are made up of the organic blockers zinc and titanium which stay on the surface of your skin (don't absorb) and block UV rays. They're VERY safe (no skin irritation). But also thick, and you look like this...

Retinoids are the ONLY 'miracle' skincare ingredient.

They treat acne, pigmentation, scarring, fine lines/ wrinkles, and even have anti-cancer effect. But most people use them wrong, end up with irritated skin, and stop. Here's the RIGHT way to use them in your routine... 👇 1/ START LOW: topical retinoids are available in both over the counter and prescription strengths. Here's the order of strength:

OTC: retinol < retinal/retinaldehyde < adapalene 0.1%
Prescription: tretinoin 0.025% < tretinoin 0.05% < tretinoin 0.1% < tazarotene 0.1%

🙋🏽‍♂️ Dermatologist here! Let me tell you everything you need to know about male pattern hair loss in one tweet thread. We’ll cover causes, differential diagnoses, and treatment options. 🧵 1/ Causes: at the crux of male pattern hair loss is a substance called ‘DHT’ - a super potent form of testosterone which specifically affects DHT sensitive hair at the front, sides and crown of the scalp. This is why it’s these areas where male pattern hair loss first presents! 2/

💰 NFT projects are just money hungry founders, hiding behind claims of pious 'community-building', making false promises of future 'perks' their tokens will enable with no clear plan/ ability to achieve them. Now... announcing @ApeDocs, my NFT project...(no, seriously...) 1/ 🧵 😳The irony of ^ is not lost on me. Jokes aside though, I do think worthwhile NFT projects exist, they're just TINY in number. Those are ones I hope to emulate, BUT, I think it's VITALLY important that, first and foremost, those new to NFTs understand the scammers' playbook. 2/

💉 As a dermatologist, I think 95% of the truly scientific skincare tips that you should know can fit into one Tweet thread. All Instagram/YouTube/TikTok skincare education videos just repackage a few core principles with different dances/ brand names. Let me prove it... 🧵 1/ 🔤 Rule 1: Moisturize. At its core, the skin is a barrier that keeps the outside world out, and the inside world of your body in. If that barrier gets dry/cracked, local cells are unhappy and get inflamed = itchy/red. So, moisturize to keep barrier in tact. Pick products... 2/

💣 This one is going to be a mine-field... Here's why I decided to pursue a medical career in the US 🇺🇸 rather than the UK 🇬🇧. NOTE: this is not me saying what OTHER people should do, simply giving my own thinking. You are free to disagree, there's no 'right answer'. 🧵 1/ 🤩 New Experience: I'd spent the majority of my life in the UK, dad was a doctor, I went to a 'good school', got into a 'good uni', and became a doctor. Felt like if I stayed in UK, best case scenario, my life would just be on repeat, now through dad's eyes. Felt too safe. 2/

I went to one of the top 10 medical schools in the world (Imperial College London), got a 'distinction' in every exam, in every year, and scored in the top 1% on the #USMLE Step 1 when moving to the USA. Here's my 5 tips for how to study more effectively for exams... 🧵 1/ 🙅🏽‍♂️ 1) NEVER compare your study style with ANY other student. The #1 cause of anxiety and confusion amongst students is looking at those around them and being convinced that they're doing something wrong, or 'falling behind'. Every single year, there would be some students... 2/

💞 I've been married now for over 5 years, so I thought this might be a good time to share 5 tips that I think would be useful for those early on in a relationship, or those just planning ahead! (PS: my wife thankfully doesn't have Twitter, so I can dish the dirt...) 🧵 1/ 🙏🏼 1) It is ALWAYS a team effort. It may seem like there's some tasks that only one of you is doing e.g. taxes, bills, making social plans, decorating etc. But the only reason you can spend your time doing that task, is BECAUSE your partner is taking care of other stuff! 2/
