The verdict
A gentle, fragrance-free serum with five forms of hyaluronic acid that Reddit fans rely on for simple, non-sticky hydration.
Torriden DIVE IN Serum, also sold as the DIVE-IN Low Molecular Hyaluronic Acid Serum, is a water-light hydrating serum built on five forms of hyaluronic acid with panthenol and allantoin. Torriden cites a non-irritant patch test and moisture gains in small in-house studies, and its ingredient list includes no fragrance. Reddit users describe it as gentle, fast-absorbing and non-clogging under moisturizer. It hydrates rather than targets tone or lines, and some find the dropper leaves the last of the serum behind.

How it scored
Five factors, weighted for formulas. Here’s our working.
Beauty score out of 10. Brands can’t pay for placement — ever.
Reddit users consistently report gentle, effective hydration, but it is a hydrator with no actives for tone, texture or lines, so visible change is limited to plumper-feeling skin.
Five forms of hyaluronic acid plus panthenol, allantoin and a little ceramide NP in a fragrance-free base; the brand's moisture claims rest on small studies of about 20 people.
A light, fast-absorbing serum that users say sinks in quickly and layers under creams without stickiness, though one user complains the dropper never reaches the last of it.
$24 for 50 ml is reasonable for a hyaluronic acid serum, in line with other K-beauty hydrators and well below prestige versions.
Frequently recommended in r/AsianBeauty, r/KoreanBeauty and r/tretinoin as a gentle, sensitive-skin-friendly hydrator, with complaints focused on packaging rather than results.

4 verbatim quotes · 3 positive · 1 critical
For lightweight daytime hydration, I highly recommend Torriden Dive-In Low Molecule Hyaluronic Acid Serum. It’s super gentle, sinks in fast, and doesn't clog pores.
Or for a serum just for pure hydration, I’ve started the torriden dive in serum recently and that one is great too.
Serum/Toner that I really enjoy are the Torriden Dive in Serum/Toner. It’s very gentle and unlikely to cause skin reactions.
And Torriden Dive-In serum. The dropper never gets the last bit and it drives me nuts. Just make it a pump already
