Dr. Kho Layered Serum AM vs PM: Which Time Works Best?

Routine Science
The same serum that plumps by day can break you out by night — here’s why timing matters.
Expert Analysis · Honest Reviews · Real Results
1.☀️Day glow vs night no

Used this AM for a week — looked dewy, not greasy. Used it PM for two nights — woke up with a chin crater.

The difference isn’t the serum. It’s what you put on top. Sunscreen locks in the plumping. Night cream seals in the breakout.

2.🌙What you’re actually buying

$48 for 30ml. The brand claims it “builds skin’s moisture barrier in 7 days.” I called bullshit until day 4.

1

Three-layer texture

Feels like water, then gel, then nothing. Absorbs in 9 seconds flat.

2

No fragrance game

Smells like nothing. My reactive skin didn’t even twitch.

3

Dual-use claim

Says AM and PM. Liars. My skin said PM is a trap.

3.🧪The ingredient tea

Three layers of hyaluronic acid — low, medium, high molecular weight. They penetrate at different depths so you’re not just wet on the surface. Plus ceramides and something called “polyglutamic acid” that holds 4x more water than HA.

  • Sodium Hyaluronate: surface plumping, no stickiness
  • Hydrolyzed Hyaluronic Acid: sinks deeper, actually lasts
  • Ceramide NP: repairs the damage you did with that retinol
  • Polyglutamic Acid: the overachiever that locks everything in

4.The AM vs PM verdict

Squeezed two drops — feels like cold silk. Spreads across my whole face in 3 pats. Dries down to nothing. No tackiness. No waiting.

Week 2: AM use = skin looks filtered. PM use = tiny whiteheads on my jawline. Turns out layering it under a heavy moisturizer traps bacteria. Who knew.

💡

One Thing: Apply to damp skin — not dry. Spritz your face first. The HA needs water to grab or it pulls moisture *from* your skin. Learned that the hard way.

5.📊The real results

Fine lines around my mouth? Less obvious by week 3. The weird dry patch near my nose? Gone by day 5. But my pores didn’t shrink — they just looked less sad because they were actually hydrated.

Buy if
You have dehydrated skin that drinks products and still wants more

Skip if
You sleep with a thick night cream or live in a humid climate — it’ll suffocate

Worth it?
$48 for a serum that lasts 2.5 months. Cheaper than a single facial. Yes.

6.💡Final call

AM only. Forever. This is a daytime plumping serum that moonlights as a breakout trigger if you use it wrong.

7.8/10
Great AM, risky PM
