Retinol Night Serum

A night treatment built around encapsulated retinol, so it releases slowly instead of hitting your skin all at once. That's what keeps it from being harsh. Bioactive peptides and Swiss-derived stem cells go to work while you sleep, helping with fine lines and tone, while ectoin and squalane keep your barrier intact so you're not left red or flaky in the morning.

The standout here is acetyl tetrapeptide-2 paired with tripeptide-2, which supports collagen and helps skin recover overnight. It's the combination that sets this apart from a standard retinol. We recommend it to retinol lovers, but also to people who've had bad reactions in the past. The encapsulation method releases slowly, so it works for sensitive skin too, not just the people who've built up a tolerance.

WHY IT WORKS+
  • Slow-release retinol without the irritation
  • Supports firmness and collagen recovery overnight
  • Keeps the moisture barrier intact without morning redness or flaking
HOW TO USE+
Apply 2-3 pumps to clean skin, as part of your 5th step, each evening. Start 2–3 nights a week if new to retinol, building up as skin adjusts. Follow with moisturizer, if desired.

ACETYL TETRAPEPTIDE-2 & TRIPEPTIDE-2

The signaling peptide behind this formula activates receptors in skin's dermis, triggering the same pathway skin uses to build new collagen, supporting firmness from within, rather than sitting on the surface.

encapsulated retinolSlow-release format, less irritation than a standard retinol
ectoinBarrier defense that holds moisture under stress
squalaneLightweight, non-comedogenic lipid that mimics skin's own oils

FIND OUT MORE ABOUT THE NIGHT SERUM
WHERE DOES THIS FIT IN MY ROUTINE?+
Apply as the 5th step of your evening routine, after cleansing and exfoliation, before moisturizer (if desired). It's designed to work while you sleep.
IS IT SAFE FOR SENSITIVE SKIN?+
The encapsulated retinol releases slowly rather than all at once, which is designed to make it more tolerable for sensitive or reactive skin than a standard retinol. If you're new to retinol, start 2–3 nights a week.
CAN I USE IT WITH OTHER ACTIVES?+
We recommend not layering with additional retinoids or strong acids outside of the ÆONS line to avoid over-exfoliating. The actives in our numbered system were formulated to work together without causing reactivity.
HOW SOON WILL I SEE RESULTS?+
Most people notice a difference in texture and tone within a few weeks of consistent use; collagen-supporting benefits build over several weeks of nightly application.
