AM vs PM: The Science of When to Use Retinol

Routine Science
Why dermatologists insist retinol belongs in your PM routine, not your morning one.
Expert Analysis · Honest Reviews · Real Results
1.🌙The Night Shift

Putting retinol on in the morning is like drinking coffee before bed. A total waste — and it might backfire.

Sunlight deactivates retinol’s potency. You’re using a weakened product, then going straight into UV exposure which increases irritation. It’s a double-whammy of pointless.

2.🔬The PM Protector

The Paula’s Choice Clinical 1% Retinol Treatment. $68. I needed a formula that wouldn’t make me peel like a snake.

1

Encapsulated Retinol

Releases slowly to cut the sting.

2

Soothing Peptides

Calms skin *while* the retinol works.

3

Airless Pump

Keeps the light- and air-sensitive ingredient fresh.

3.🧪What’s In The Bottle

It’s not *just* retinol. That would be harsh. The base is full of repair agents.

  • Retinol (1%): The gold-standard cell-communicating ingredient
  • Bakuchiol: Plant-based retinol-alternative that soothes
  • Peptides: Signal skin to produce more collagen
  • Licorice Root + Oat Extract: Calm redness on contact

4.The Feel of It

Feels like a silky moisturizer — not greasy, not sticky. Absorbs in 20 seconds. Zero residue.

Week 2: My skin was softer, but I got one tiny purge pimple. A sign it was actually working. It was gone in 3 days.

💡

One Thing: Apply it *over* your toner/essence on damp skin. It spreads easier, uses less product.

5.🛌Did It Deliver?

After 6 weeks: Pores look vacuumed. Fine lines above my lip are shallower. My rosacea didn’t flare — a miracle.
