This article covers general skincare after cosmetic treatments such as chemical peels, microneedling and laser or light treatments. It doesn't replace the aftercare advice your practitioner gives you, and their instructions always come first.
A good treatment can leave skin looking fresher for weeks. The days straight afterwards are a different story: skin can feel tight, warm and oddly sensitive, and the temptation is to reach for everything on the shelf to help it along. Usually the opposite works better. Here's what is going on, and how to keep aftercare simple.
Why skin feels different after a treatment
Many aesthetic treatments work by disrupting the skin's surface on purpose. A chemical peel loosens the outer layers, microneedling creates tiny channels, and lasers and other energy-based devices deliver controlled heat. Skin then responds and renews. In the meantime, the barrier that normally holds moisture in and keeps irritants out isn't working at full strength.
That explains the familiar signs: tightness, a warm or flushed look, stinging from products that usually feel fine, and dryness or light peeling as the days go on. None of this means something has gone wrong. It means skin is busy, and needs you to make its job easier rather than harder.
What a recent expert review suggests
A 2025 expert review in Aesthetic Surgery Journal Open Forum (Goodman and colleagues) looked at skincare around energy-based treatments such as lasers. Its central point is simple: the more a treatment disrupts the skin barrier, the more care you need in choosing what goes on afterwards. As a general guide, it suggests:
- Pausing retinoids and exfoliating acids for roughly 4 to 12 days after a light treatment, and two to three weeks after a more intensive one.
- Skipping toners while skin is settling.
- Wearing a broad-spectrum sunscreen every day, before and after treatment.
- Choosing a moisturiser to match how skin feels: a hydrating cream after something light, and a richer, more cushioning one after something more intensive.
Treat those timings as a starting point, not a rule. Your practitioner knows exactly what was done and how deep it went, so their timing wins.
A simple aftercare routine
Morning
- Cleanse gently, or simply rinse with lukewarm water if your practitioner prefers. Pat dry rather than rubbing.
- Moisturise with something fragrance-free and soothing. Our Red Algae Calming Day Moisturiser is a silky, fragrance-free cream built on organic aloe, with red algae, jojoba and hyaluronic acid.
- Sunscreen, every day, even when it's grey. Freshly treated skin is more vulnerable to sun, and protecting it helps the result you paid for last.
Evening
- Cleanse gently again, with no scrubs, brushes or exfoliating pads.
- A comforting night cream. The Red Algae Calming Night Cream pairs mango butter and jojoba with multi-weight hyaluronic acid, and is fragrance-free. If skin is dry and flaky, the richer Cloudberry Velvet Night Cream, with cocoa and shea butters, is also fragrance-free.
What to leave out for now
- Retinoids, retinol and exfoliating acids (glycolic, lactic, salicylic), until your practitioner says otherwise.
- Scrubs, brushes and peeling masks. Let flaking skin come away on its own rather than picking or buffing it.
- Toners and anything with a strong tingle. If a product stings, rinse it off.
- Fragrance and essential oils, which are among the most common cosmetic irritants for reactive skin.
- Brand-new products. Freshly treated skin is a poor place to test something for the first time.
- Makeup, for as long as your practitioner advises.
Injectables are a little different
After injectables, most of the skin's surface stays intact, so there is less barrier to look after. The aftercare that matters is your practitioner's own instructions, with a simple, gentle routine around them.
Bringing your usual routine back
Once skin feels like itself again, with no tightness, stinging or peeling, start reintroducing your usual products one at a time, a few days apart, beginning with the gentlest. Leave retinoids and acids until last, and only once your practitioner is happy. Going slowly makes it easy to spot anything skin isn't ready for.
When to call your practitioner
Some redness and sensitivity is expected. Contact your practitioner straight away if you notice blistering, oozing or crusting, redness that spreads, or pain or swelling that gets worse rather than better.
In short
After a treatment, skin needs less, not more: a gentle cleanse, a soothing fragrance-free moisturiser, daily sunscreen, and patience while it settles. Follow your practitioner's aftercare first, and bring actives back slowly.
