A tattoo on your ankle, a beauty mark on your upper lip, a birthmark on your back, or last weekend's mehndi still on your hands: none of these rule out laser hair removal. They do change how your technician works. Laser finds hair by its pigment, and anything else in the skin that carries pigment, such as tattoo ink, a dark mole or a henna stain, can absorb the same energy. That is why a careful technician maps these spots at your consultation, covers or skips them during treatment, and treats the skin around them. This guide explains what happens with each one, what you should mention before your first session, and when a spot deserves a doctor's look before any cosmetic treatment.

Why Pigment in the Skin Matters
Laser hair removal is based on a principle called selective photothermolysis. Light of a specific wavelength is absorbed by a specific target, in this case the melanin in your hair, and turns into heat. That heat damages the follicle while, ideally, leaving the skin around it unharmed.
The laser cannot tell the difference between melanin in a hair and other dark material that happens to sit in the same spot. Tattoo ink, a concentrated patch of melanin in a mole, or dye from henna can absorb the energy too. At best, that wastes energy. At worst, it overheats the skin and causes a burn, a blister or a lasting mark. Medical reviews of laser complications list burns and pigment changes among the main risks, and most are avoidable with the right technique.
The simple rule
If it is darker than your surrounding skin and it is not hair, your technician protects it. That usually means covering it, leaving a margin around it, or adjusting the settings nearby.
Tattoos
Hair removal lasers are not tattoo removal lasers, and they should never pass over tattoo ink. Dark ink in particular absorbs the energy strongly. The result can be a burn, blistering, and a tattoo that is blurred, faded or changed in colour.
How we handle tattoos
- ●We treat all the skin around the tattoo and leave a small margin untouched.
- ●Small tattoos may be covered during treatment so they are easy to avoid.
- ●Hair growing inside a tattoo cannot be lasered. Most clients simply shave or trim that patch.
- ●New tattoos must be fully healed before we treat the skin nearby.
A tattoo in the middle of a treatment area, such as the lower back, upper arm or ankle, does not stop you from treating the rest of the area. It just leaves a small untreated island.
Microblading, Lip Blush and Permanent Makeup
Cosmetic tattoos are common among our clients, especially microbladed brows and lip blush. The same rule applies: no laser over the pigment. Cosmetic tattoo pigments can react to laser energy and change colour, which is not something anyone wants on their face.
In practice, this rarely gets in the way. We do not laser eyebrows at all, so microblading is outside the treatment area. For upper lip laser with a lip liner or lip blush tattoo, your technician keeps a margin away from the border of the lip. If you are planning new permanent makeup, tell your artist that you are doing laser nearby, and let us know too.
Moles and Beauty Marks
Moles are clusters of pigment-producing cells, so darker moles absorb laser energy. We avoid them, often covering them during treatment. There is a second good reason to leave moles alone: you want them to stay easy to watch. Changes in a mole are one of the most important early warning signs of skin cancer, and a cosmetic treatment should never make that harder to see.
See a doctor before laser if a mole shows any of the ABCDEs
- ●Asymmetry: one half does not match the other.
- ●Border: irregular, scalloped or poorly defined edges.
- ●Colour: several colours, or uneven shades of brown, black, red, white or blue.
- ●Diameter: usually larger than a pencil eraser, though melanoma can be smaller.
- ●Evolving: changing in size, shape or colour, or itching or bleeding.
This checklist comes from the American Academy of Dermatology. If we notice a spot that looks unusual during your consultation, we will skip it and suggest you have it checked. We are not diagnosing anything. We are just being careful.
Hair growing out of a mole is very common, especially on the face. Laser cannot treat it safely because the mole sits right over the follicle. Trim it close to the skin. If you want it gone for good, a doctor can assess the mole and discuss removal.
Birthmarks, Freckles and Sun Spots
Pigmented birthmarks
Flat brown birthmarks (such as café-au-lait spots) and blue-grey birthmarks hold extra pigment. We treat around them, not over them.
Red or purple birthmarks
Vascular birthmarks, like port-wine stains, are made of blood vessels rather than pigment, but they still react to some wavelengths. Tell us about them, and check with your doctor if they are large or have been treated before.
Freckles and sun spots
Scattered light freckles do not usually stop treatment, but dense or dark patches may be avoided or treated with adjusted settings. They can look temporarily darker after a session. Our GentleMax Pro is used for hair removal only, so this is not a treatment for sun spots. If pigmentation is your concern, see our hyperpigmentation options.
Henna, Self-Tanner and Scars
Mehndi and henna. This one comes up constantly in wedding and festival season. Henna stains the top layer of skin a deep orange-brown, which adds pigment exactly where the laser works. Wait until the stain has fully faded before lasering that area. If you have a wedding or Eid or Diwali coming up, plan your arm and hand sessions before your mehndi night, or pause them until afterwards. Our Diwali glow prep guide has a full timeline. Be especially cautious with “black henna”, which often contains a dye that can cause serious skin reactions on its own.
Self-tanner and spray tans. Same principle. Let it wear off completely before a session, and do not apply it between sessions on treated areas.
Scars and keloids. Flat, healed scars are usually fine to treat around. If you have a history of keloids or raised scars, tell your technician so they can patch test carefully and keep settings conservative.
What to Tell Your Technician
At your consultation, your technician looks over the areas you want treated and notes anything to avoid. It helps if you mention:
- ●Any tattoos in or near the area, including new or healing ones.
- ●Microblading, lip blush, eyeliner tattoos or other permanent makeup.
- ●Moles you are keeping an eye on, and any that have changed.
- ●Recent henna, self-tanner or sun exposure.
- ●A history of keloids, cold sores (for face treatments) or reactions to past laser.
None of this is unusual, and none of it is likely to stop you from getting treatment. It just helps us do it safely. For the rest of your preparation, read our step-by-step prep guide.

Frequently Asked Questions
Can you do laser hair removal over a tattoo?
+
No. Tattoo ink absorbs laser energy much like hair does, so lasering over a tattoo can burn the skin and damage or change the tattoo. We treat the skin around your tattoo and leave a small margin untouched. Hair growing inside the tattoo can be shaved or trimmed instead.
Can I get laser if I have a lot of moles?
+
Yes. Your technician avoids or covers moles and treats the skin around them. Dark moles hold a lot of pigment and would absorb energy meant for the hair. Leaving them untouched also means they stay easy for you and your doctor to monitor.
Can hair growing out of a mole be removed with laser?
+
Not safely with laser, because the mole sits right on top of the follicle. You can trim the hair close to the skin. If you want the mole or its hair removed permanently, talk to your doctor or a dermatologist, who can assess the mole first.
I have microblading or lip blush. Can I still get face laser?
+
Usually, yes, with care. We do not laser the eyebrows, so microblading is not in the treatment area. For lip blush or lip liner tattoos, your technician keeps a margin away from the pigmented border when treating the upper lip. Laser energy can change the colour of cosmetic tattoo pigment, so always tell us about any permanent makeup.
How long after a new tattoo can I get laser nearby?
+
Wait until the tattoo has fully healed, with no scabbing, peeling or tenderness, before having laser on the surrounding skin. For most tattoos that is at least four to six weeks. Your tattoo artist's aftercare advice comes first.
Can I have laser after mehndi or henna?
+
Wait until the stain has completely faded. Henna colours the top layer of skin, which can absorb laser energy and raise the risk of irritation or uneven results. Plan laser sessions before your mehndi, or after the colour is gone.
Should I get my moles checked before laser?
+
If you have any mole that is new, changing, itchy, bleeding or looks different from your others, see a doctor before your laser session. The American Academy of Dermatology's ABCDE checklist is a helpful guide. Laser hair removal does not treat moles, and we will not treat over a spot that looks concerning.
