Laser resurfacing in London. Ablative and non-ablative approaches, skin type, downtime, and the questions that decide whether it is safe for you.
Laser resurfacing uses light absorbed by water in the skin to remove or heat tissue in a controlled way, prompting the surface to renew and the dermis to remodel. Ablative devices remove tissue and do more. Non-ablative devices heat without removing and need more sessions.
Conditions this treats
The cost of laser resurfacing in London depends on which laser, how much of it and how many passes. Price is driven by whether the treatment is ablative or non-ablative, the area covered, the number of sessions, whether a test patch and topical preparation are included, and the operator's training on that platform.
Cost follows the assessment rather than preceding it. What treatment costs sets out how a written quotation should be built, and the guide to choosing a skin clinic covers what an unusually low figure has normally had removed from it.
Laser resurfacing produces change that continues developing for three to six months after treatment as collagen remodels. A fractional ablative course commonly holds for several years, non-ablative treatment for a shorter period with sessions repeated. Sun exposure after treatment is what shortens the result most reliably.
A laser emits light at a single wavelength. Resurfacing devices use wavelengths absorbed strongly by water, which is abundant in skin, so the energy is deposited where it is aimed and converted to heat. Depending on the device and the settings, that heat either vaporises tissue or heats it without removing it.
Resurfacing is usually the most disruptive thing you will do to your skin, so it should sit at a sensible point in a plan rather than at the start of one. Skin that is actively inflamed, actively breaking out or actively pigmenting is skin that will heal unpredictably, and treating it produces the complications this page has spent several sections describing.
A reasonable order runs: settle any active skin disease first, medically if that is what it takes. Establish daily sun protection and, where appropriate, a retinoid, for several weeks. Treat pigmentation topically before treating it with light. Then resurface. Then maintain.
Spacing matters afterwards too. Convention is to leave around two weeks between resurfacing and injectable treatment in the same area, and considerably longer after ablative work. Facials, waxing, threading and abrasive products should be left alone for at least a fortnight, and often longer, and the practitioner should tell you when to restart each rather than leaving you to guess.
Finally, plan the maintenance before you book the treatment. A resurfacing result sits on skin that continues to age and continues to be exposed to ultraviolet light. Without daily protection and a reasonable routine, the improvement erodes, and the erosion is usually blamed on the laser rather than on the six months that followed it.
Laser resurfacing is safe when skin type is recorded, a test patch is performed and settings are chosen for that skin rather than for a protocol. The principal risks are post-inflammatory hyperpigmentation, prolonged redness, infection including cold sore reactivation, and scarring where energy or depth has been misjudged.
Melanin absorbs laser light. In darker skin there is more melanin in the epidermis to absorb energy that was intended for elsewhere, which raises the risk of burns and, far more commonly, of post-inflammatory hyperpigmentation.
That does not mean laser is unavailable in skin of colour. It means device selection, wavelength, density, energy and cooling all have to be adjusted, that treatment should be more conservative, that priming and post-treatment pigment management matter more, and that a test patch is essential rather than optional.
A small area treated at the intended settings, then reviewed after an appropriate interval, tells you how your skin responds before your whole face is committed. A clinic that declines to patch test, or offers to do it in the same appointment as full treatment, is not managing the main risk.
For skin of colour specifically, radiofrequency microneedling is frequently a better first choice because it disrupts the epidermis far less. See radiofrequency microneedling.
Expect a recorded skin type, a test patch and a plan for pigmentation before treatment is booked. On the day the area is numbed and treated in passes. Non-ablative downtime runs two to five days; fractional ablative treatment weeps, crusts and peels for five to fourteen days with strict aftercare.
This is where expectations most often fail, because recovery is routinely understated in marketing.
Plan for it properly. Take time off if the treatment warrants it. Arrange the appointment when you are not about to travel somewhere sunny, and expect to be strict about sun protection for months rather than weeks. See aftercare.
Choosing where to have laser resurfacing in London means checking the operator and the oversight, not the wavelength. Ask which device is used and why, whether your skin type is recorded and test patched, what training and medical supervision exist, how pigment complications are managed, and how the clinic handles a poor healing response.
The clinic guide covers verification of the last question in detail.
Laser resurfacing is not suitable during pregnancy, over active infection or an erupting cold sore, on tanned or recently sun-exposed skin, or after recent isotretinoin until the prescriber agrees an interval. Melasma is treated cautiously or not at all, and keloid-prone skin needs a test area and a careful discussion.

The same order every time, with the decision made at assessment rather than at the point of sale.
The skin is examined in consistent light and the finding is named before laser resurfacing is discussed as an answer to it. Skin type, medical history, medicines and the routine you are already using all change the plan.
For energy-based treatment, particularly in higher Fitzpatrick types, a test patch and a wait rather than a full treatment on a first visit.
The finding, the treatment, the number of sessions, the interval between them, what you use at home and what it costs, in writing.
Conservative settings first, escalated across a course on the basis of how your skin actually responded rather than on a fixed protocol. Afterwards, non-ablative: 2 to 5 days. Fractional ablative: 5 to 14 days.
Written aftercare covering sun protection, what to apply, what to stop and the signs that mean you telephone rather than wait.
Where the finding will not respond to this treatment, that is said plainly and the correct route is discussed instead of a compromise.
One to three for fractional ablative treatment, three to six for non-ablative, depending on the finding and the device.
It can be, with appropriate device selection, conservative settings and a test patch. Radiofrequency microneedling is often preferred because it spares the epidermis.
Two to five days for non-ablative, and seven to fourteen for fractional ablative with residual pink for weeks afterwards.
Aggressive laser can worsen melasma considerably. It is managed with topicals, strict sun protection and, where light is used at all, very cautious settings.
Numbing cream is standard and stronger anaesthesia may be used for ablative treatment. Afterwards the skin feels like severe sunburn for a day or two.
Outside periods of high sun exposure and when you are not about to travel somewhere bright. Ultraviolet exposure afterwards is what drives pigmentation.
Modestly at best. Resurfacing improves surface quality. Significant laxity needs a different conversation.
Treatment
Microneedling with heat added. More remodelling, more downtime, considerably more operator dependency.
