What is the Revlite laser and how does it work?
Revlite is a Q-switched Nd:YAG laser system that was first developed by another manufacturer and is now associated with Cynosure.
Q-switched lasers release energy in nanosecond-range pulses. The short pulse is intended to break up target pigment particles through a mechanical shock rather than slow heating, and the body then clears the fragments gradually. The Nd:YAG medium can work at 1064 nm for deeper pigment and at 532 nm for more superficial brown pigment.
The defining feature of this class is that it targets coloured structures rather than heating the whole face like a general resurfacing device. Technical details such as extra wavelengths and spot-size options vary by model and version, so it is reasonable to ask which unit is used.
When is it considered?
It may be assessed for sun spots, some age spots, freckle-like brown marks and uneven skin tone; tattoo removal is a separate subject.
Q-switched Nd:YAG lasers have long been used in dermatology for superficial and mid-depth pigment problems and for tattoo removal. Some practitioners also use low-energy, repeated pulses with the aim of evening out skin tone. How much benefit any person gets varies, and expectations should stay realistic.
Importantly, not every mark is suitable for laser. Whether a brown lesion is melasma, post-inflammatory pigment, a mole or a precancerous lesion should be established first. A mark that is changing, growing or bleeding needs dermatological assessment before any laser treatment.
What does a session feel like?
A session is usually short; many people describe each pulse as a rubber band snap, and some feel mild stinging.
The skin is cleansed, eye protection is fitted and a topical numbing cream may be used. The laser is applied in small spots over the target area. Depending on the size of the area, the time ranges from a few minutes to about half an hour.
Afterwards there may be redness, mild swelling and temporary darkening or fine crusting of the spot. The crusts should be left to shed naturally. The number of sessions and intervals depend on the type and depth of the spot and on skin tone, and a single session is often not enough; results cannot be guaranteed.
What are the risks, and who may not be suitable?
Temporary redness, crusting, darkening or lightening of the spot can occur, and rarely burns or lasting colour change; the risk is higher on darker skin tones and on tanned skin.
Recent sun exposure or tanning, active infection or cold sores, pregnancy and breastfeeding, photosensitising medicines and isotretinoin use can change or postpone the plan. A tendency to keloid and conditions such as vitiligo are also considered. Tell the physician about every medicine and skincare product you use.
Managing side effects is the physician's responsibility. If there is unexpected pain, fluid-filled blisters, widespread redness or signs of infection, do not treat it yourself and contact the clinic.
How should aftercare and sun protection look?
Avoiding sun and using the moisturiser and sunscreen the physician recommends have a direct effect on healing and on the risk of new pigment.
After pigment lasers the skin can be more sensitive to the sun. Broad-spectrum high-protection sunscreen and physical shade matter during this period. The physician will say when sauna, pool and intense exercise can resume.
Spots can return if sun exposure and hormonal triggers continue. Protection and, where needed, skincare products are therefore at least as important as the laser itself for keeping results. See the laser aftercare page for more detail.
Frequently asked questions
Is Revlite used for melasma?
Melasma is delicate, and incorrect energy settings can darken it. Some physicians consider low-energy protocols, but suitability and alternatives are decided at consultation.
Can Revlite remove tattoos?
This laser class is used for tattoo removal; results depend on colour, ink depth and skin tone, and many sessions are usually required.
How many sessions are needed?
It depends on the type and depth of the spot. The physician plans according to the response after the first session; results are not guaranteed.
Does it hurt?
Discomfort varies by person and area. Brief stinging and warmth may be felt, and a topical numbing cream can be used if needed.
Can I return to normal life straight away?
Most people can, but redness, crusting and temporary darkening may appear. Discuss timing with the physician before an important event.
