Mizon Hyaluronic Acid 100 Ampoule: AM or PM Application?

Routine Science
One hydrating serum works 24/7—but here’s why you should only use half of it at night.
Expert Analysis · Honest Reviews · Real Results
1.🌅Daytime is a trap

You don’t need this under sunscreen. I don’t care what the bottle says.

Using it in the AM just makes your moisturizer slide around like a greased pancake. Save the slip for night.

2.🌙What you’re actually buying

It’s a watery serum — 100ml for like $16. Mizon claims it “floods skin with moisture.” I call it a cheap thrill that actually works.

1

Three-drop rule

More than 3 drops = sticky face on your pillow. Don’t be greedy.

2

Damp skin only

Slap this on wet skin or it does nothing. I mean dripping wet.

3

Layer it last

Put this after toner, before anything heavy. It’s a water bomb, not a sealant.

3.🧪The ingredient shortlist

It’s basically 100% hyaluronic acid + water. No fragrance, no alcohol, no drama. But the molecule size matters — this uses low-molecular-weight HA so it actually sinks in instead of sitting on top like a plastic film.

  • Sodium Hyaluronate: Sucks moisture from the air into your skin
  • Hydrolyzed Hyaluronic Acid: Smaller molecules = deeper penetration
  • Water: Carrier. Not exciting. Necessary.
  • No fragrance: Won’t make you sneeze at 2AM

4.🕐How it actually feels

It’s basically water. No jelly, no slime. Absorbs in like 8 seconds if your face is damp. Two seconds if your face is dry and you’ll hate it.

Week two: I woke up with less crepe-y texture around my eyes. But my T-zone got a little oilier — turns out over-hydrating can trick your pores into party mode.

💡

One Thing: Mix one drop into your night cream. Spreads better, locks in moisture, zero stickiness.

5.💧The real results

My fine lines looked softer — not gone, just less pissed off. Did it change my life? No. Did it stop my skin from feeling like parchment by 3PM? Yes.
