Nice!! I don't know much about that moisturizer but the rest looks good to me

Seems like the evidence is overwhelmingly in favor of sunscreen, the studies I've seen against it generally seem to not address the obvious confounder that people who tend to wear sunscreen more are also the ones who have a lifestyle that involves being in the sun a lot more.

I think it is pretty conclusive that sunscreen wearing will improve your skin complexion and smoothness in the long term (presumably the effect is not worth having if you never go outside in sunshine, obv).  Whether it has enough material effect to do anything to your risk of dying from malignant melonoma (which is pretty rare anyway), is more of an open question. It might not be a worthwhile trade-off for everyone.

  • I used to get breakouts maybe like once a month, sometimes with really stubborn/painful zits that would take quite a long time to disappear. Now I basically never get breakouts, I think I've had like 2 small zits since I started and they have disappeared quickly. I have not had any big painful ones.
  • My fine lines have been reduced, my skin looks and feels smoother and softer
  • I had some redness/discoloration in some areas which has been reduced a lot - no longer needs to be covered with makeup

Dermatica prompts you to send them photos every few months so they can check how your skin is reacting, but it's also convenient because you can look back and see the improvement.

Has anyone tried Visia skin analysis to get feedback loops on skinhealth? (they reveal WAY more than just pictures) The problem with camera images is that visible light doesn't capture fine lines or wrinkles. My skin SEEMS to look as perfect as that of a 12-year old on the outside, but there is some small amount of wrinkling under my eyes that a visia reveals (which is why this thread prompted me to finally get dermatica tretonin)  Collagen peptides also can help increase collagen synthesis and relieve fine lines (it's my biggest pet peeve b/c I can't stand ingesting animal products, and this is the only thing Bryan Johnson will ditch veganism for). And it's really irritating that there isn't more vegan collagen available.

Very helpful, thank you for the extra detail!

It says to reapply every two hours but I... do not do that 😅 I put it on in the morning and would reapply if I was spending time outside. I don't know how important the "every 2 hours" thing is

2O O
I believe it's 2 hours of sun exposure. So unless you are spending all day outside, you should only need to apply it once. I personally apply it once before going to work.

Oh nice! My retinoid formula and moisturizer have hyaluronic acid mixed in so it's hard for me to isolate its effects, but a lot of people seem to find it hugely beneficial

Answer by rosiecam*6721

I did a bunch of research on this a while ago, here are my high-level conclusions:

  • This video is worth watching: Ali Abdaal’s “My evidence-based skincare routine
  • Sunscreen and retinoids get you almost all the way there.
  • Sunscreen:
    • Wear it on your face everyday. 
    • Most sunscreen feels horrible and slimy (especially in the US where the FDA has not yet approved the superior formulas available in Europe and Asia). 
    • The best is Elta MD (UV Clear Tinted Face Sunscreen, SPF 46 Tinted Sunscreen with Zinc Oxide). It’s expensive, but it feels fine on your face,

What superior formulas available in Europe would you recommend?

What do you think is the strongest evidence on sunscreen? I've read mixed things on its effectiveness.

I watched this video and this is what I bought maximizing for cost/effectiveness, rate my stack: * Moisturizer * Retinol * Sunscreen

  Just wondering if you could expand on just what improvements you see? What features or criteria are you looking at and how you have been measuring the changes?

I feel *so* pedantic making this comment — please forgive me — but also:

CeraVe may have degraded in quality when they were purchased by L’Oréal and potentially changed the source of the fatty alcohols in their formulation. Fatty alcohols that have been sourced from coconut are more likely to cause skin irritation than those that have been sourced from palm. Plus, retinoids can actually push these fatty alcohols deeper into the pores for the ultimate backfire effect.

Weird side effect to beware for retinoids: they make dry eyes worse, and in my experience this can significantly decrease your quality of life, especially if it prevents you from sleeping well.

Regarding sunscreens, Hyal Reyouth Moist Sun by the Korean brand Dr. Ceuracle is the most cosmetically elegant sun essence I have ever tried. It boasts SPF 50+, PA++++, chemical filters (no white cast) and is very pleasant to the touch and smell, not at all a sensory nightmare.

How long does the Elta MD sunscreen last?

I live and die by hyaluronic acid. It doesn’t create permanent changes AFAIK but makes a massive difference for me day to day — plus or minus 5 years depending.

Thanks I appreciate that :) And I apologize if my comment about probability being weird came across as patronizing, it was meant to be a reflection on the difficulty I was having putting my model into words, not a comment on your understanding

Ok this confirms you haven't understood what I'm claiming. If I gave a list of predictions that were my true 50% confidence interval, they would look very similar to common wisdom because I'm not a superforecaster (unless I had private information about a topic, e.g. a prediction on my net worth at the end of the year or something). If I gave my true 50% confidence interval, I would be indifferent to which way I phrased it (in the same way that if I was to predict 10 coin tosses it doesn't matter whether I predict ten heads, ten tails, ...

Also, I apologize for the statement that I "understand you perfectly" a few posts back. It was stupid and I've edited it out.

1Rafael Harth
I'm arguing against this claim: I'm saying that it is harder to make a list where all predictions seem obviously false and have half of them come true than it is to make a list where half of all predictions seem obviously false and half seem obviously true and have half of them come true. That's the only thing I'm claiming is true. I know you've said other things and I haven't addressed them; that's because I wanted to get consensus on this thing before talking about anything else.
I hereby offer you 2000$ if you provide me with a list of this kind

Can you specify what you mean by 'of this kind', i.e. what are the criteria for predictions included on the list? Do you mean a series of predictions which give a narrow range?

1Rafael Harth
A list of predictions that all seem extremely unlikely to come true according to common wisdom.

I agree there is a difference between those lists if you are evaluating everything with respect to each prediction being 'true'. My point is that sometimes a 50% prediction is impressive when it turns out to be false, because everyone else would have put a higher percentage than 50% on it being true. The first list contains only statements that are impressive if evaluated as true, the second mixes ones that would be impressive if evaluated as true with those that are impressive if evaluated as false. If Tesla's stock ends up at $513, it feel... (read more)

1Rafael Harth
Well, now you've changed what you're arguing for. You initially said that it doesn't matter which way predictions are stated, and then you said that both lists are the same.

Thanks for the response!

I don't think there is any difference in those lists! Here's why:

The impressiveness of 50% predictions can only be evaluated with respect to common wisdom. If everyone thinks P is only 10% likely, and you give it 50%, and P turns out to be true, this is impressive because you gave it a surprisingly high percentage! But also if everyone says P is 90% likely, and P turns out to be false, this is also impressive because you gave it a surprisingly low percentage!

I think what you're suggesting is that people should always... (read more)

(Edit: deleted a line based on tone. Apologies.) Everything except your last two paragraphs argues that a single 50% prediction can be flipped, which I agree with. (Again: for every n predictions, there are 2n ways to phrase them and precisely 2 of them are maximally bold. If you have a single prediction, then 2n=2. There are only two ways, both are maximally bold and thus equally bold.) I have proposed a rule that dictates how they are phrased. If this rule is followed, it is not arbitrary how they are phrased. That's the point. Again, please consider the following list: * The price of a barrel of oil at the end of 2020 will be between $50.95 and $51.02 (50%) * Tesla's stock price at the end of the year 2020 is between 512$ and 514$ (50%) * ... You have said that there is no difference between both lists. But this is obviously untrue. I hereby offer you 2000$ if you provide me with a list of this kind and you manage to have, say, at least 10 predictions where between 40% and 60% come true. Would you offer me 2000$ if I presented you with a list of this kind: * The price of a barrel of oil at the end of 2020 will be between $50.95 and $51.02 (50%) * Tesla's stock price at the end of the year 2020 is below 512$ or above 514$ (50%) * ⋯ and between 40% and 60% come true? If so, I will PM you one immediately. I think you're stuck at the fact that a 50% prediction also predicts the negated statement with 50%, therefore you assume that the entire post must be false, and therefore you're not trying to understand the point the post is making. Right now, you're arguing for something that is obviously untrue. Everyone can make a list of the second kind, no-one can make a list of the first kind. Again, I'm so certain about this that I promise you 2000$ if you prove me wrong.

As has been noted, the impressiveness of the predictions has nothing to do with which way round they are stated; predicting P at 50% is exactly as impressive as predicting ¬P at 50% because they are literally the same. I think one only sounds more impressive when compared to the 'baseline' because our brains seem to be more attuned to predictions that sound surprisingly high, and we don't seem to notice ones that seem surprisingly low. I.e., we hear: 'there is a 40% chance that Joe Biden will be the democratic nominee' and som... (read more)

If that were true, then the list * The price of a barrel of oil at the end of 2020 will be between $50.95 and $51.02 (50%) * Tesla's stock price at the end of the year 2020 is between 512$ and 514$ (50%) * ⋯ (more extremely narrow 50% predictions) and the list * The price of a barrel of oil at the end of 2020 will be between $50.95 and $51.02 (50%) * Tesla's stock price at the end of the year 2020 is below 512$ or above 514$ (50%) * ⋯ (more extremely narrow 50% predictions where every other one is flipped) would be equally impressive if half of them came true. Unless you think that's the case, it immediately follows that the way predictions are stated matters for impressiveness. It doesn't matter in case of a single 50% prediction, because in that case, one of the phrasings follows the rule I propose, and the other follows the inverse of the rule, which is the other way to maximize boldness. As soon as you have two 50% predictions, there are four possible phrasings and only two of them maximize boldness. (And with n predictions, 2n possible phrasings and only 2 of them maximize boldness.) The person you're referring to left an addendum in a second comment (as a reply to the first) acknowledging that phrasing matters for evaluation.

I'm constantly experimenting with it! The downside of it being so flexible is that it can take a while to figure out the best system.

At the moment, everything goes into one database called 'Notes'. I enabled the 'Created at' and 'Edited at' properties. I also have multi-select properties for themes (e.g. rationality, productivity, economics, etc) and for type (e.g. random thought, blog idea, resource, article, tool, etc). I also have a checkbox property called 'processed' - and I filter the view of the table to... (read more)

Principles:

  1. Capture everything: Do not assume your brain will remember anything. Write it down ASAP. Use whatever will let you capture it quickest, whether that's pen and paper or a digital solution.
  2. Review and process: Make sure you actually look at the things you wrote down regularly and organize it. If it was an idea you need to act on (e.g. a topic for a blog post, or a reminder to look up a particular concept), add it to your task manager. If it was a thought for reference, add it to your 'second brain'/note-taking/archive system, and add

For recurring tasks, I use checkvist. You can embed your lists into Notion pages.
3Peter Kim
Do you mind sharing your Notion setup? I've been thinking about setting up a personal wiki with it, but I'm unsure of how to best structure it overall. I've just started a bare-bones system for planning and task management, but I'm still getting the hang of using Notion effectively.

There seems to be some evidence that a norm of helmet-wearing discourages people from cycling. When people don't wear helmets, they are taking on some personal risk, but by challenging the norm it could mean that more people take up cycling. This is likely to make cycling safer (fewer cars on the roads, drivers are more used to cyclists, safety in numbers at intersections etc), and so the need to wear a helmet is reduced.

I'd prefer to live in a world where more people cycle and helmets aren't (as) needed (like in European cities such as Berlin and Amsterdam), so I tend to feel grateful towards people who don't wear helmets.

This is great, I can see it being really helpful for me to consciously think about which of these I'm optimizing for (or am willing to sacrifice) when writing. I got confused by the introduction of the term 'density' in the section on trade-offs, as this isn't represented in the RAIN framework. Is density just a sub-consideration of accessibility or are you considering it in its own right?

3ozziegooen
Thanks, and good to hear! Density applies only to some situations; it just depends on how you look at things. It felt quite different from the other attributes. For instance, you could rate a document "per information content" according to the RAIN framework, in which you would essentially decouple it from density. Or you could rate it per "entire document", in which case the density would matter.

FWIW, there seems to be a trend in my corner of the AI safety community (CHAI) to move away from the term 'values' and towards the term 'preferences', I think for similar reasons.
