This is the routine I give people who have already read the theory, know their barrier is damaged, and want to be told exactly what to do on which day.
If you are not sure that is what you are dealing with, start with what a damaged skin barrier actually looks like first. Treating the wrong problem for four weeks is a waste of four weeks.
Why the face is different from the rest of the body
Facial skin is thinner, has more sebaceous glands, and gets exposed to far more product than anywhere else. It also gets the most sun, the most cleansing and the most friction. So a barrier routine for the face has to be gentler than one for hands or legs, and it has to survive daily sunscreen.
The other thing specific to the face: this is where people apply actives. Almost every damaged facial barrier I hear about was caused by a routine, not by weather. Weather makes it worse. Routine causes it.
Week 1: subtract
You are not adding a repair product this week. You are removing the cause.
Stop entirely: every acid, every retinoid, every vitamin C, every scrub, every cleansing brush, every clay mask, every sheet mask with fragrance.
Morning: rinse with lukewarm water. No cleanser. Hydrating toner on damp skin. Moisturiser. Sunscreen.
Evening: if you wore sunscreen, oil cleanse then a brief gentle second cleanse. If you did not, one gentle cleanse. Hydrating toner on damp skin. Moisturiser.
That is four products and it should stay four products.
What to expect: stinging should drop noticeably by day four or five. If it has not, your cleanser is almost certainly the problem. See the gentlest cleansers for a compromised barrier.
Week 2: rebuild lipids
Same routine. One change: the moisturiser does more work.
Apply it to skin that is still visibly damp, morning and night. If your skin is very dry, apply a second thin layer at night about ten minutes after the first. The SKIN1004 Probio-Cica Enrich Cream is what I reach for here most often, or the Anua Heartleaf 70% Intense Calming Cream if redness is the dominant symptom.
If you want one addition, make it a calming ampoule between toner and moisturiser: Anua Heartleaf 80% Soothing Ampoule or SKIN1004 Madagascar Centella Ampoule. Not both.
What to expect: redness begins to settle. Flaking may briefly look worse around day 9 to 11 as the surface turns over. That is normal and it passes.
Week 3: hold
This is the week people ruin. The skin looks fine. It is not finished.
Change nothing. Add nothing. If you must add something, one plain hydrating serum, and nothing else for the rest of the week.
What to expect: stinging gone, texture smoothing, redness mostly resolved. Underneath, lipid production is still normalising.
Week 4: test, then reintroduce one thing
The test: apply a plain hydrating toner and wait sixty seconds. Zero stinging, zero tingling, zero heat. If you get any of the three, you are not ready. Hold another two weeks.
If you pass, add back one active, at the lowest strength and frequency:
- A retinoid: twice a week, at night, applied after moisturiser rather than before for the first month. The SKIN1004 Centella Retinol 0.2 Boosting Shot is buffered with centella and is a sensible re-entry point.
- Or an acid: once a week, no more.
- Or a vitamin C: three mornings a week.
One of those. Not two. Hold at that frequency for two full weeks before increasing anything.
What goes wrong in week 4
- Adding two things because the skin looks good. The most common relapse by a wide margin.
- Going back to the original frequency. If you were using a retinoid nightly before, nightly is what broke it.
- Reintroducing the cleanser that caused the problem. If your old cleanser left your face squeaky, do not go back to it at all.
- Assuming winter will not undo it. If you are in Canada and it is between November and March, indoor humidity is doing real damage. A bedroom humidifier costs less than a serum and does more.
What if four weeks passes and nothing improves?
Then it probably is not a damaged barrier.
Persistent facial redness that flushes with heat, alcohol or spice, and comes with visible small blood vessels, points to rosacea. Redness with greasy flaking around the nose, eyebrows and hairline points to seborrhoeic dermatitis. Itchy, weepy, well-defined patches point to eczema. All three are medical, all three are treatable, and none of them will resolve with a cream from us.
Four weeks of a correct barrier routine with no change is a good reason to see a doctor rather than to buy something else.

Common questions
Can I wear makeup during the four weeks?
Yes. Remove it with an oil or balm followed by a brief gentle wash, rather than a foaming cleanser alone.
Should I stop sunscreen if it stings?
No. Change the sunscreen. Stinging usually comes from alcohol or fragrance in the formula, and there are plenty without either in Daily Protection.
Is four weeks always enough?
Four weeks gets most faces to looking normal. Full resilience is closer to six to eight. Badly damaged skin can take longer.
Can I use a sheet mask?
Fragrance-free and alcohol-free only, twice a week at most. Long wet contact can disrupt the barrier by itself.
What if the stinging comes back in week 5?
Drop the active you reintroduced, go back to the week 2 routine for fourteen days, then try again at half the frequency.
