Post-Treatment Skin

Many aesthetic treatments work by deliberately disrupting the skin's surface. A chemical peel loosens the outer layers, microneedling makes tiny channels, and lasers and other energy-based devices deliver controlled heat. The aim is for skin to respond and renew, but for a while afterwards the barrier that normally keeps moisture in and irritants out is not working at full strength. That is why skin can feel tight, warm and unusually reactive, even to products it normally tolerates.

A 2025 expert review in Aesthetic Surgery Journal Open Forum makes the point simply: the more a treatment disrupts the skin barrier, the more care is needed 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, and wearing a broad-spectrum sunscreen every day.

In practice, aftercare is mostly about subtraction. A gentle cleanser, a soothing, fragrance-free moisturiser and daily sun protection cover most of what skin needs in the first days. Hydrating ingredients such as hyaluronic acid and aloe help skin feel comfortable, while richer creams with plant oils and butters cushion dry, flaky patches. Actives, scrubs and new products can wait until skin feels like itself again.

Injectables are a little different, because most of the skin's surface stays intact. The aftercare that matters there is your practitioner's own instructions, and a simple routine around them.

Whatever the treatment, your practitioner's aftercare advice comes first, including their timing for reintroducing actives. If you notice blistering, oozing, spreading redness, or pain or swelling that gets worse rather than better, contact them straight away.
