The five states
Vulnerable+
Post-peel, bare
Nothing on your face. Barrier is temporarily more permeable from the acid — more open than a normal cleanse. Most reactive window.
Moisturize immediately. Don't go outside yet. Don't apply anything else active.
Vulnerable
Post-cleanse, bare
Clean face, nothing on it. Barrier is intact but completely unprotected. Normal starting point before any routine.
Apply your routine promptly. Fine to stay bare for a few minutes — not a crisis, just a prompt.
Active
Retinol or AHA working
An active is on and absorbing. Not protected — your skin is more reactive right now, not less.
Don't layer anything on top. Don't touch your face. Let it absorb fully before moisturizing.
Sealed
Moisturizer on, no SPF
Physical layer over your barrier. Wind, cold, minor contact — buffered. No actives working. Maintenance state.
You right now. Safe to go outside at night. Not protected against UV — that needs SPF.
Protected
Full AM routine + SPF
Actives applied, moisturizer on, SPF on top. UV defended. Barrier supported. Peak daytime state.
Holds through the day. Degrades by evening from sweat, touch, and UV exposure eating the SPF.
How long does protected last
Morning → noon
Peak protected. SPF intact. Actives absorbed and working.
Noon → 3pm
Still mostly protected indoors. SPF degrading with exposure.
3pm → evening
Sliding toward sealed. SPF mostly spent. Moisturizer residue still there.
Post-gym / night
Sealed at best. Cleanse and start your PM routine.

Tomorrow
Peel on Thursday creates a natural buffer — recovery on each side. Move peel day anywhere, keep one recovery night on each side.
Spot treatment — as needed, not routine
Dr. Dennis Gross Sulfur Spot Treatment
Apply directly to active breakouts only, after your main routine has absorbed (last step, or after moisturizer if your skin is reactive). Not a nightly all-over product. Safe on any night type — retinol, recovery, or peel — as long as it's a targeted dab, not a layer.
Avoid combining spot treatment with fresh peel skin if your barrier is compromised. On peel nights, skip it or wait 30+ min post-moisturizer.
Copper Peptides — compatibility rules
Retinol nights only — applied after retinol, before COSRX. Copper peptides are incompatible with direct acids (peel, glycolic toner) which degrade them on contact, and with vitamin C — the Filorga oil serum contains ascorbic acid, so copper peptides must go before it, not after.
Never in AM — Mela B3 and the Filorga oil's ascorbic acid are both a conflict. Never on peel or glycolic toner night — the acids will degrade the peptides before they can absorb.

Glycolic Toner — as a peel swap
Can replace the TO peel on weeks your skin feels more sensitive — same standalone night rules apply, nothing else active. It's milder (7% vs 30% AHA), no rinse, same recovery stack after.
Can also become a second exfoliation day (currently slotted Sunday) once you've had a few weeks on the TO peel alone. The TO peel is strong — adding a second exfoliation day too soon risks barrier damage. Get comfortable with the TO peel first.

Your specific scenarios
Gym + water rinse only
Water removes sweat and surface residue but doesn't strip your barrier. Moisturizer is partially still there underneath.
Sealed, degraded
Fine to leave if sleeping soon. Ideally do your full PM cleanse and routine after gym — water rinse is not a substitute for cleansing.
Gym + cleansing or baby wipes
Wipes strip more than water — especially baby wipes, which aren't pH-balanced for facial skin. More disruption, less residue left behind.
Closer to vulnerable
Worse than a water rinse if you're not doing a full routine after. If you are, doesn't matter — just a messier path to the same place.
Waking up with PM routine still on
Moisturizer has been sitting overnight — skin has been regenerating under it, but the layer is stale and spent. Not harmful, just inactive.
Sealed, stale
This is why you cleanse in the morning even though you washed at night. Clear the stale layer before applying fresh actives.
After peel → moisturized → nighttime walk
No UV at night so sun sensitivity isn't a factor. Barrier is temporarily more open, but moisturizer seals it. Wind is the only real concern.
Sealed — safe to go out
Wait 10–15 min after moisturizer before heading out. Cold wind on bare post-peel skin = bad. Moisturizer on post-peel skin = fine.
