Held back

  • RetinolPaced: 2 nights a week to start
    Why

    2 nights a week to start. Steps to 3 nights around Dec 5 if you have kept up with it and your skin is settled.

  • Glycolic tonerSet aside: conflicts with Retinol
    Why

    Set aside. It conflicts with Retinol serum on the same night. Comes back once Retinol serum is settled, around Jan 2. Today asks first.

What happened
  • Nothing yet. Tap tonight's dot.

Steps up at 70 percent of scheduled nights done. Prescription retinoid: follow your prescriber's instructions. Corneo schedules the rest.

Check a pair

Retinol or retinal (retinoid) and Glycolic or lactic acid (AHA): Yes, but not on the same night.

Sunscreen every morning

Why

Retinol or retinal (retinoid) + Glycolic or lactic acid (AHA)

Yes, but not on the same night

Use them on different nights: a retinoid and an exfoliating acid on the same night is a reliable way to get irritated.

Corneo routine rules, H2

Retinoids and exfoliating acids make skin more sensitive to the sun: wear sunscreen every morning. (H1)
