The appointment is the smaller half of the work. A resurfacing treatment creates a controlled injury and your skin spends the following week rebuilding — and what you apply during that week either supports the rebuild or interrupts it.
Below is what our advisors actually tell people, by treatment type. Your clinician's instructions always take precedence over anything here; this is the general shape.
The first 48 hours, whatever you had done
Cleanse with something that does nothing but cleanse. No acids, no scrubs, no brushes — a gentle non-foaming cleanser, lukewarm water, and a soft towel you pat rather than rub.
Then barrier support and nothing else. This is not the moment for actives, and it is absolutely not the moment to test whether your skin is ready for them.
Sunscreen from the morning after, without exception. Freshly resurfaced skin pigments easily, and post-inflammatory hyperpigmentation is far harder to correct than it is to avoid. A mineral SPF sits better on healing skin than a chemical one.
After a peel
Expect tightness for a day or two, then flaking around day three to five. Do not help it along. Picking or exfoliating peeling skin is the single most reliable way to turn a good peel into a patch of pigmentation that takes months to fade.
Keep it simple and occlusive: cleanse, barrier moisturiser, SPF. Restart actives when the flaking has finished entirely, usually day five to seven.
After microneedling or RF microneedling
Channels in the skin stay open for several hours, so the first night is the strictest part — only what your clinician gives you. From day two, barrier repair and hydration. A product built for compromised skin, like ZO's Redness Relief and Barrier Defense range, does more here than anything targeted.
Retinol comes back last, typically at a week. If you were mid-ramp, drop back one step rather than resuming where you left off.
After laser or IPL
Pigment lifts to the surface and darkens before it clears — that is the treatment working, not a reaction. It sheds over one to two weeks. Heat is the thing to avoid: no hot showers, no saunas, no strenuous exercise for the first 48 hours.
Sun exposure in the following month will undo the result, so this is the treatment where SPF discipline matters most. If you are treating pigmentation, our dark spots guide covers the maintenance routine that holds the result between sessions.
The mistake we see most
Not the aftercare itself — most people follow it carefully for the first three days. It is week two, when the skin looks good and everything gets restarted at once: the retinol, the acid, the vitamin C, the exfoliating cleanser. Reintroduce one product at a time, three or four days apart, and you will know which one caused a problem if one does.
If you want to understand a specific treatment before booking it, the Skinfolio Skin Journal covers the procedures themselves in detail. This side of things is about what happens after you leave.
