Review of settling on the "moisturizing on the outside, moist on the inside" hydrating item I always stock up on during Olive Young sales (ft. Torriden)

The weather has been so unpredictable lately that my skin has been feeling extremely dry from the inside, so I've been really worried.
I have typical dehydrated skin; it's shiny on the outside due to sebum, but feels tight and dry underneath.
No matter how thickly I applied a rich nourishing cream or moisturizing cream before going to bed, the effect was only temporary.
It was a vicious cycle where my face would turn red and dry again after I woke up and washed it the next morning.
Then, a friend advised me that for inner dryness, I absolutely must start by thoroughly replenishing moisture with an ampoule.
So, during the Olive Young sale, I bought the famous Torriden Dive In Low Molecular Hyaluronic Acid Serum with my own money.
When I first tested it on the back of my hand, I was honestly skeptical because the texture was too watery.
I had doubts, wondering, "Can such a lightweight formula really tackle my terrible internal dryness?"
However, right after washing my face, I gently wiped off the moisture, pumped this serum twice, and rolled it all over my face, and it was a whole new world.
It didn't feel like it was sitting on the surface of the skin at all; as soon as I applied it, it absorbed right in, just like a sponge soaking up water.
There was absolutely no stickiness or heaviness, yet surprisingly, I felt a firm, bouncy sensation as moisture was completely and thoroughly filled from deep within the skin.
It seems the claim that it absorbs deep into the skin well because it is low molecular weight hyaluronic acid was true.
I layered this serum about two times, patted it in to absorb, and then finished by applying a thin coating of Physiogel DMT Cream.
The morning after I changed my skincare routine and went to sleep, I looked in the mirror and was really surprised to see that my skin had become clearer.
The tightness I used to feel every morning has completely disappeared, and when I touch my skin, it feels chewy and bouncy like mochi.
Even when doing your makeup in the morning, if you lightly soak a sponge with this serum and pat on your foundation, your base will never cake.
It’s amazing that my makeup doesn’t crack or dry out even when I’m under the air conditioner or heater all day long.
It seems to have a slight soothing effect as well; the small bumps that used to pop up have subsided a lot, and my skin texture has become smooth.
It has become my holy grail product, to the point where I feel anxious if it isn't on my vanity, and I am already on my third bottle, scraping every last bit out of it.
While dermatological treatments are good, I think the most important thing is ultimately opening up the moisture pathways in the first step of your daily home care routine.
If you are someone who wants skin that is moist on the outside and moist on the inside, rather than crispy on the outside and moist on the inside like me, I highly recommend giving this a try.
If you also have a holy grail moisturizing product that you've settled on, I would be grateful if you could share the details in the comments!
