Empties Masterpost?

A habit I've picked up from my mother: dating the longevity of household items. Growing up as a kid I remember dates written in Sharpie across the tubes of toothpastes in our house. This is no different, but now I've come to wonder how long the products I've been using over and over last. What is the day/cost ratio and is it worth it? A bit slow to the game since I've been paying attention to skincare regimes for a while, but better late than never. 2019 is the year of dates.

1.  Missha Clear Toner 250 ml, $16 (sale of course).  1-22-19 to 7-15-19.
2.  SKII First Treatment Essence (7.8 oz/ 230 mL from duty free). 2-19-19 to 9-12-19.
3.  Estelle & Thild Biocalm Soothing Day Cream (50ml - used/free). 7-12-19 to 9-27-19.
4.  Goodal Natural Clear moist cleansing foam (150 ml, Club Clio Sale $10?$5?). 7-12-19 to 11-19-19. 
• This one lasted a really really long time considering both my sister and I were using it night and day.
5. Mizon All-in-One Snail Skin Repair Cream - 75ml Amazon - 9-28-19 to 11-20-19. 
• This jar hardly lasts me two months, and doesn't quite quench my skin. Even though it absorbs really well and I love how it has no scent, it's not enough and goes too quickly. On to the next one; haven't found my holy grail of moisturizers yet.
6. Mizon Black Snail Cream? I don't actually remember what moisturizer I used, but it was fine.
7. Beauty of Joseon Dynasty Cream 50ml- Amazon- 1-20-20 to 2-14-20
• Hardly lasted a month! Had to use because was in skin trouble because the Soo'Ae Soy Bomb lotion I was using didn't do anything (Club Cleo clearance for $5 and it's not worth my time at all, just skintertainment) and needed to help my skin out.. fast!
8. Elizavecca hyaluronic acid water drop cream 1.7 ounce, Amazon - 2-13-20 to 2-20-2020? Gosh that was fast. Didn't maintain a good enough record.
9. Used Soo'Ae soy bomb lotion, IT IS AWFUL, and makes my wrinkles worse. Dumped to use on my body instead of face. All Soo'Ae products have been awful to use and I will never buy such substandard quality products again.
10. Second jar of Goodal Young Barley Sparkling Gel Cream, gave it to my mom but she rather use the overly fragranced Neutrogena hydro moisture cream that burns my face when I put too much on.
11. Boscia Cactus Water Moisturizer 3.4 FL OZ 4-15-20 to 7-11-20 bought from Costco for $30. Goes on like Aloe, and takes a bit to sink in, but it wasn't bad and I bought another when I saw it on sale for $15. I like that this lasts me for just under 3 months. Which is more than I get out of most of my moisturizers. 
12. My Beauty Diary's Ultra Facial Cleanser. Bought a little 40g sample in Taiwan ages ago. Lasted me 4/15 to 7/15, which is amazing for a little thing. So much goes a long way, but I didn't like how much it foams because I felt like it was a bit harsh on my skin. Need that middle ground of feeling clean, but actually getting cleaned. Lasts a long time.
13. Missha Clear Toner 250 ml, (Amazon? Missha sale? I don't remember...) 12-22-19 to 9-5-20 wow that's a long time. This is my go-to toner. It's a part of the ferments line that is supposed to imitate SK-II's idea. It doesn't, but I do love this affordable toner that I usually get anywhere from $15-20, even though right now I only see it via Sokoglam and things for $28. Smells a little fermenty, feels like water, and I slap the stuff on my face. Honestly, I don't know what it is, but I do know that no other toners compare. I love this stuff, I am sad to see I'm rotating it out for a risk I bought at a Club Clio clearance. And there's this missing gap between toners, I don't even remember the last toner, but I wanted it out. I think it was Klairs's famous toner and it was unremarkable to me.
14. COSRX Hyaluronic Acid Hydra Power Essence 3.4 fl oz, 9/26/20-7/21/21

Wow I'm behind, definitely went through another bottle of SKII that's not mentioned on here. So, this is inaccurate.
