1.🌙The AM Retino-No

Putting retinol on in the morning is like drinking espresso before bed. Technically possible, but deeply counterproductive.

Sunlight deactivates it. You’re literally wasting the product and irritating your skin for zero benefit.

2.🔬The Night Shift Serum

This is The Ordinary‘s Retinol 0.5% in Squalane. $7.80. The claim? Real results without the luxury markup.

1

Mid-Strength

0.5% is the sweet spot for beginners who’ve graduated from retinoids.

2

Squalane Base

An oil, but not a greasy one—it mimics your skin’s own moisture.

3

Dropper Bottle

You control every drop, which is key because you only need three.

3.⚠️What’s Actually In It

It’s a two-ingredient workhorse. The retinol speeds up cell turnover. The squalane locks in moisture to buffer the irritation.

  • Retinol 0.5%: The star player that tells your skin to renew itself
  • Squalane: A hydrating cushion that prevents the classic retinol peel
  • That’s it. Seriously.
  • No fragrance, no fluff.

4.The Feel of It

It feels like a light, silky oil. Absorbs in about 90 seconds—you’re not a greaseball all night.

Week 2, my skin got that weird tight-but-not-dry feeling. A sign it’s working. I doubled down on moisturizer.

💡

One Thing: Apply it *after* your moisturizer on damp skin. It buffers the intensity without diluting the effect.
5.🛌Waking Up Different

After a month, my pillowcase texture changed. Smoother. Skin looked blurred—like a subtle Instagram filter IRL. Blackheads? Gone. Deep wrinkles? Still there, but softer.
