Hi ^^ For years now I’ve been really bothered by all the misinformation on the internet about skincare. So let’s put an end to that so that you can all have amazing skin for back to school! Here’s everything you ever wanted to know about skincare. Enjoy!

The very basics

READ THE INGREDIENT LIST: I don’t care if your moisturizer is $60, it most likely has the same awful ingredients as a drugstore one but with a fancier packaging and smell. Ingredients are what makes or breaks a product and not just the ‘miracle x ingredient’ advertised on the packaging, every other ingredient is just as important.

Ingredients are all the same, if it says grapeseed oil, you’re getting grapeseed oil, it’s not higher quality because the product is more expensive.

I know you’re going ‘ain’t nobody got time for that’ but PLEASE, make time for that. Just quickly scanning the ingredient list, you’ll be able to spot harmful ingredients and save your money.

The more towards the bottom an ingredient is, the less of that ingredient the product contains. Meaning if the product claims to have x ingredient but it’s towards the bottom, it’s as good as nothing.

USE SUNSCREEN. Yes, every day. Even if it’s cloudy. Even if you’re staying inside. @educatier made a wonderful post about it, but here are the main reasons why you should:

UVA rays go through windows and are present as long as the sun is out. They cause AGING and SKIN CANCER. UVB causes burning and tanning.

Acne is an inflammatory disease (discussed below). The sun causes inflammation. The sun WILL make your acne worse.

Acne scars are mostly inflammation and melanin. Sun rays will basically etch them onto your skin.

Any products you put on your face will be basically wasted. At the rate the sun damages your skin, no anti-oxidant, retinol, whatever can work fast enough to help your skin repair itself. If you want a visual annalogy, your skin cells are like construction workers, any products you put on are like machinery that helps them build. Sun rays are wrecking balls.

If you’re using retinoid, benzoyl peroxide or salycilic acid (discussed below), and not using sunscreen, you’re basically ageing yourself twice as fast.

The acid mantle

The acid mantle is a lipid layer that keeps your skin’s pH slightly acidic (around 4.5). Products that have a much higher/lower pH will compromise it. This will cause dehydration, slower repair rate (read: acne scars for longer) and make a general mess out of your skin.

Why irritation is so harmful

When a product irritates your skin, it stimulates the nerve endings under your skin. One of the consequences of this is that they send a signal to your oil glands to produce more oil (more acne, yay!). It’s also been shown to cause collagen breakdown

Some Tips On Organic Chemistry

When you’re looking at two compounds and wondering how they may react, pay attention to the carbons - if they are bonded to a halogen or something more electronegative than them, then they have a partial positive charge and they’re going to want anything that will give them more electrons (a.k.a. a nucleophillic attack). If they’re bonded to hydrogen, they have a partial negative charge and they become your nucleophile, which will want to give those electrons to something that’s lacking them. Once you get these basics down, mechanisms become much easier to memorize because you can see the logic in them and sometimes predict them.

Get the basic mechanisms ingrained in your brain. Think of SN1, SN2, E1 and E2 as your new multiplication table. Make flashcards about them and take them to class. Or put them at the back or front of your notebook. Just have them handy at all times.

Draw the final steps in 3D. ALWAYS. You can draw the mechanisms and the first steps in 2D because it will make it easier to understand, but never forget that you’re working with a 3D structure that can flipped (and attacked by nucleophiles) every which way. Also, if you don’t know the basic perspectives used in orgo (Fischer, Newmans, sawhorse, wedge-dash) please take half an hour to learn them. Mainly wedge-dash and Fischer, but Newman is very useful when deciding which position you should put your atoms in if you’re dealing with sin and anti.

Colors. If you’re one of those people who ONLY writes in black pen, awesome, keep using it for WRITING. For reactions though, you’re going to want options. you’ll need to differentiate between:

The molecules (same color for atoms and bonds, unless you want to finish your notes on your deathbed).

Your three types of arrows: electron flow, actual steps in the reaction (think intermediates) and steps you may take to make it clearer for you but that happen at the same time.

Formal charges

The electrons that stay with its original atom and the ones that are given/shared, if you’re like me and you like your mechanisms to be spelled out.

This is not an excuse to go nuts with the coloring, 3 colors are enough. Personally, I use purple for molecules, electrons and reaction arrows, black for electron flow arrows and charges and light blue for clarification step arrows. Also optional but to denote a homolytic fission I usually write a blue line perpendicular to the bond. Similarly, if two atoms share one electron each, instead of just one them donating both electrons, I link said electrons with blue.

Remember to be consistent, otherwise you’ll end up like me, looking at your notes from the beginning of the semester and wondering if that dash is a bond or a -1 formal charge (to avoid this, preferably circle formal charges. Lol I never do this but I should).

Flashcards are so helpful! Write the reactants on one side and the mecanism and products on the other. Test yourself until you are one with the electrons.

If it’s a concerted mechanism, number the arrows. You’ll thank yourself a month from now.

Khanacademy. Khanacademy will save your butt when it comes to mechanisms. Chemwiki is likely to have anything that Khanacademy doesn’t. If it isn’t in either of those, Google images just became your new best friend. Books also tend to explain those nicely but I personally find them to be poorly structured and they usually include much more info than what you’ll actually be requiered to know. If you have the time to read two pages on a reaction though, by all means go for it.

Study in advance. Good luck studying for your final two days before if you don’t understand the mechanisms and you don’t have your material organized. Seriously, don’t do it. A week before the exam you could make those flashcards mentioned above. They’re a great way to review but it will be impossible if you are learning these things from scratch.

Get your hands on past tests. This goes for any subject but especially for orgo. Try to get a past test or at least ask an upper-classman who’s taken orgo with that professor. Does his/her tests focus on mechanisms? Retrosynthesis? Or does he/she give you the reactants and ask what the product is or what environment they should be in to obtain x? Ideally, you should be able to answer any of these if you know the material. However, if they focus on retrosynthesis, it may be a little tricky, so make sure to cater your study techniques to that.

You should also check out @colllegeruled’s Surviving Organic Chemistry, it’s super helpful and it has lots of resources (seriously, you introduced me to Khanacademy, I OWE YOU MY LIFE).

So, this is what I can offer so far. I hope it shines at least a faint light into the dark path that is organic chemistry.

University Tips (non-conventional)

If these help anyone, great!

Wear sports bras/bralettes to lectures instead of the ones with a buckle at the back. They tend to poke and prod your back after a while if you’re leaning back. Sports bras don’t.

Set your timetable as your phone background for the first few weeks. Use this method for no. 6 too if you can be bothered. 

Lay a towel on your bed a few days before your period is due. If you leak on a towel you can just wash it or throw it away. Easier than washing and changing the sheets.

When you’re in a lecture taking notes on a laptop remember to turn down the brightness on your screen, especially if the lecturer has dimmed the lights. Otherwise you’ll annoy others and drain your battery. 

Save your recordings at every given break instead of making one continuous one through pausing. Sometimes files are too large to save and you don’t want to risk losing the entire lecture recording. Save as you go along.

If you need to remember something (e.g. a library book, USB, locker key..) write it on a post-it note and stick it on your shoes before you sleep. Make sure they’re the shoes you intend to wear the next day!

Don’t shoot me: if you have left an assignment really late, stay up as long as you can completing it (yes, that means an all-nighter may be needed). Sleep as soon as you’ve handed it in. 

If you use tech in a lecture e.g. phone for recording or electronic notetaking on your laptop, then mess around with it before uni begins. Know what buttons to press and when, otherwise you’ll mess up your notes and annoy others, with your excessive clicking. 

Always, always, ALWAYS carry a plastic bag/carrier bag. You might need to make a trip to the library, drink may spill in your bag so you’ll need an alternative or you may not be able to dispose of a pad/tampon until you get back home. Seriously, just carry one.  

Find out where coursework/assignment are submitted within your first week on campus. Ask admin how the procedure works and make sure you know it inside out. 

I’ll update this list as things come to me. I hope it helps, this is all my opinion, sorry.
