----SKINCARE GUIDE----

“Sunscreens are like mayonnaise” is my new favourite quote 💜

[Kasey]

The thought of skin care products dissolving a container, while still being safe on my face, is one of those great examples of how very cool chemistry is.

I love how she takes difficult to understand science stuff and breaks it down for us. The analogies are my favorite part!!

Me buying spf 50 sunscreen because I know I be applying like SPF 25 of it on my skin.

One mistake I've found out, sadly from personal experience, applying body sunscreen at the beach and not at home. I will rush it and end up missing spots, applying somehow less and the end results are guaranteed sunburns at places that are hard to reach. Whenever I take my time and apply it at home (and with regular reapplication at the beach) I never have this problem.

If you leave sunscreen in your car in Phoenix during the summer, the bottle will disintegrate. So you won’t have the worry about reusing the sunscreen. Your only concern will be to clean the mess out of your car.

Michelle is my savior! I used to demonize certain ingredients like alcohol and fragrance, until there’s a day that i always find difficulties when it comes to buy or use skincare because all my skincare seems not safe. But now i realized that how i use, how i store it, and how the product is formulated can make a huge diffrent from product to product, and it make me more relax about my skincare routine! Not to mention, skin reaction to a product is world top secret!

Oh god I was doing my skincare routine while watching this, and as soon as you said "saving up the serums from your sheet masks" I stared at the packet sitting on my counter and threw it out LOL

An advice that might be useful to others: cleaning your bottles regularly! 😉
This might be obvious to some already, but making sure your products aren't exposed to sun, dust and airborne bacteria (in case you do your routine in the bathroom) is important to keep them safe.
Also, sometimes, when we are in a hurry, we also might use more than one product in a rush, and our sticky fingers transfer the bits of a product onto the bottle of another.
I try to clean my bottles with a wet cloth regularly and wash my hands before doing my skincare routine, and it's very useful.

The 2 Finger Rule for sunscreen is my favorite way to make sure I'm getting approximately the right amount on my face. What you do is dispense the sunscreen from your palm to the tip of your index and middle finger in a line, then apply all of it to your face. I measured it once and it was approximately the right amount or a little more, and I have very small hands. It is just the easiest way for me rather than remembering what a teaspoon looks like!

I have always been hyper-vigilant about using spatulas for pots of cream/product/etc. + washing my hands before touching my face. I feel like the pandemic has helped me say “I TOLD YOU SO!” To everyone who think I take it too far 🙃

[yeuxdessirenes]

I’m so glad you’re addressing that sheet masks aren’t meant to be used twice or more. I watched a medical esthetician here on YouTube say that it was fine and that the preservatives would be able to rebalance microbes after use a single use and to use them again, and I was shocked.

[cherryblossomings]

Wow this whole time I thought you were saying “nerdification” bell 🤭

[amlaaaa]

Here are my video suggestions:
1. Self-tanner - and what products and ingredients not to use with it.
2. How to DIY cushion foundation (in particular, can you directly mix foundation with sunscreen, serums, etc - what kind of products and ingredients can foundation be mixed with directly)
3. Are there ingredients that actually make your hair fuller, grow stronger/more (e.g. Ordinary's peptides for hair)

[roohana]

dropper on the face is so annoying. To be honest whenever I see an influencer do this I stop watching them. It just annoys me the worst way simply because it makes no sense and shows they're just another copy cat.

[stefano]

I keep all my skincare in my bedroom. Always hated the idea of moisture getting into jars etc, I'm glad to hear this wasn't just an irrational fear of mine! Thanks for the very informative video.

[RaynesX]

Yeah, nice try, you just want all the face fungi for yourself.

[SamMKKK]

“...including pigment drops.”
dermablend, after going around telling people you can mix their foundation with your spf: 👀

[oddlyuncommon]

Excellent as always! Thank you for the knowledge bomb! Mistakes I have made are over exfoliating, thinking that more must be better, too many new products introduced too quickly, and not using moisturizer on my oily-combo skin when I was much younger... teen products, moisturizer specifically, back in the late 80s sucked so much.

Re Travel Containers: If the product you use has silicone in it, you cannot put it in a silicone travel tube. Learned this one the hard way.

I tend to repackage things for convenience: buy a big bottle of hand sanitizer to refill my handbag sized bottle. Hand sanitizer seems pretty safe, but when refilling things like lotions, I try to run the bottle through the dishwasher, let it air dry, then rinse it with isopropyl alcohol and let it air dry again. I've not had any problems with products going bad or creating reactions, but maybe I've just been lucky.

It would be really nice if some sort of refill standards were created. Restaurants have a whole protocol for refilling their containers and containers for food storage are designed to be washed and reused safely. It seems like a similar set of rules would help keep everyone safe.
