Eyeliner PMU Guide: Lash Line vs. Winged Liner, Design by Eye Shape, Smudging and Healing

A lash-line fill and a drawn line are different procedures

A lash-line fill (filling between the lashes, often just called a "lash line") deposits color along the upper lash line and the bare skin between lashes so the lashes look fuller. Rather than a visible line when your eyes are open, it simply sharpens the outline of the eye, so the big advantage is that it doesn't look odd on no-makeup days. When a client says at the consultation, "I don't want it to be obvious that I've had eyeliner done," it usually ends up here.

A drawn line places a line of a set thickness on the skin above the lashes and extends a tail past the outer corner to change the direction of the eye. It clearly makes eyes look longer or offsets a droopy look, but in return it's fully exposed to design trends and to how eyelids change with age. A sharp wing done in your twenties can start to look bent a few years later as the eyelid droops slightly, and a tail like that isn't easy to remove.

That's why many artists recommend a step-by-step approach for first-timers: start with a lash-line fill, live with it for a few months, and add a line if you feel it isn't enough. You can always add a line later, but taking away a line that's already in requires laser or remover treatments.

• Lash-line fill: low visibility, natural look comes first, less noticeable if it blurs, typically lasts around one to two years
• Thin line (about 1 mm just above the lashes): a crisp, made-up look that defines the eye even without a tail
• Winged line: the biggest change to your look; the hardest to correct if the design goes wrong or the eyelid changes
• Lower line: makes the look heavier and carries a greater risk of blurring, so many studios don't recommend it or only do it in very limited cases

Design changes with your eyelid type and eye shape

With monolids, the eyelid skin often covers the line when the eyes are open. That makes it tempting to think the line has to be thick to show, but then a heavy line is fully exposed whenever you close your eyes or look down, leading to complaints that it "looks stamped on." For monolids, a mostly lash-line approach with a short tail that just peeks out when the eyes are open tends to be the safe choice. At the consultation, sketch it in pencil and check it with your eyes both open and closed.

With an inner (in-fold) double eyelid, the line sits inside the crease, so widening it can let color touch the fold and look smudged. A thin line hugging the lashes is often the right fit. With an outer (out-fold) double eyelid, the line is fully visible, so even a 0.5 mm difference in thickness changes the look. The safe order is to start one step thinner than you want and add thickness at the touch-up if needed.

Check the direction of the outer corner too. On downturned eyes, forcing the tail upward makes the line look kinked when the eyes close, so a gentler angle and shorter length look more natural. On eyes that already turn up, the tail should extend closer to horizontal so the look doesn't become too sharp. From your forties and fifties, when the eyelids begin to droop, getting definition from a lash-line fill and a thin line rather than a tail looks less awkward over the long run.

Pain and swelling: the swelling is more noticeable than with brows

With numbing cream applied, people often describe the pain as "stinging" or "my eyes keep watering." Many find the lash line more sensitive than the skin above it, and if your eyes water, the artist wipes them as they go. Around the eyes, the amount and placement of numbing cream is controlled so it doesn't get into the eye, and if your eyes start to sting or burn during the procedure, say so right away rather than putting up with it.

Swelling varies a lot by person, but it's typically worst from the evening of the procedure to the next morning and settles down over two to three days. People whose eyes tend to puff up in the morning, who slept poorly the night before, or who are around their period tend to swell more. It's best to avoid booking right before an important commitment, and if you're worried about work, many people prefer a Friday afternoon appointment.

Managing swelling generally means short, repeated cold compresses wrapped in clean gauze. Avoid putting ice directly on the skin or rubbing as if pressing on the eye. If after the procedure your eye hurts badly, your vision becomes blurry, there's pus-like discharge, or the swelling gets worse rather than better after three days, see an eye doctor first, not the studio.

Who must speak up before the procedure: contacts, eye conditions and eye surgery history

Eyeliner is done right next to the eye, so if any of the following applies to you, reconsider whether to have it done at all. Recommended waiting periods vary between clinics and artists, so treat this list as a way to flag "people who need to consult first," and follow your doctor's judgment on actual timing.

Contact lens wearers need to remove their lenses before coming in on the day, and are often told to wear glasses for several days to about a week afterward. Putting in and taking out lenses means your fingers pull on the eyelid, and bacteria can reach the healing area. If you currently have lash extensions or a lash perm, the extensions get in the way of the procedure, so have them removed in advance or adjust your schedule.

• Conjunctivitis, a stye or blepharitis, now or recurring recently: the rule is to postpone until symptoms have fully cleared
• Severe dry eye requiring frequent artificial tears: irritation may be worse after the procedure, so consulting an ophthalmologist is recommended
• After vision correction such as LASIK/LASEK, or cataract surgery: first confirm with your surgeon that your eyes have fully recovered
• After eyelid surgery such as double-eyelid surgery or ptosis correction: wait until the swelling has completely gone down and the crease has settled, or the design may end up off; the guidance is typically measured in months
• Undergoing treatment for intraocular pressure such as glaucoma, or using a lash serum (including prescription ingredients): tell your artist the product name and consult a doctor if needed
• Prone to keloids, taking medication that affects blood clotting, or pregnant or breastfeeding: often the procedure should be put on hold or requires a medical professional's judgment

Why blurring happens, and how to reduce it

Eyeliner blurring is when the edges of the line soften and the color appears to spread into the surrounding skin. It's often invisible right after the procedure and only shows gradually over months or years, so someone who was happy at the time later feels "the line has gotten thicker" or "it's gone dark all the way under my eye." Black pigment sometimes looks bluish over time, and this too is related to depth and blurring.

The causes fall broadly into four groups. First, eyelid skin is thin, so if the needle goes even slightly too deep, pigment ends up in a lower layer than intended. Second, going over the same spot repeatedly to get a dark result in one session increases skin trauma and gives the pigment room to spread. Third, rubbing your eyes during healing, or pressing on them often because of the swelling, pushes around pigment that's still settling. Fourth, skin that produces a lot of oil or eyelids that have lost elasticity tend to make the line look wider over time.

There isn't a lot the client can do, but there are definitely a few things: don't ask for it to be dark in the first session, accept that depth is built up at the touch-up, and think carefully about a lower line or a long tail. At the consultation, asking "How do you handle it if blurring develops?" and "Can I see eyeliner cases that are more than a year old?" are also good ways to gauge the artist's experience. Photos taken right after the procedure make it hard to judge the risk of blurring.

Healing timeline and when to wear makeup again

For the first two to three days you may see swelling and a little weeping, and between days three and seven fine flakes form and come off. The pattern of the color lightening once and then revealing its settled color over two to four weeks is similar to brows. The touch-up is usually done four to eight weeks after the first session, and the overall aftercare principles are the same as for any PMU procedure.

What you especially need to stick to with eyeliner is eye makeup. Eyeshadow, eyeliner and mascara touch the healing area directly, and removing them means rubbing during cleansing, so the general guidance is to skip them for at least one to two weeks. Products used close to the waterline, like mascara and eyeliner, carry a risk of bacterial contamination, so when you start again, a new product is better than one you've been using for a long time. Avoid scrubbing around the eyes with an oil cleanser or makeup remover until the color has finished settling.

Beyond that, it's best to stay away from saunas, bathhouses and swimming pools for around two weeks, and to hold off on eye masks and exfoliating eye products until healing is complete. In rare cases where iron oxide-based pigments were used, there are reports of the treated area feeling warm or tingling during an MRI scan, so if you need an MRI later, just let the imaging staff know about your eyeliner PMU beforehand.
