Sulam eyeliner, lash lifts and lash tints: what can go wrong at the lash line, and what to do first

The lash line is a busy edge. It carries the eyelashes, the openings of the oil glands that keep your tears from evaporating, and the surface of the eye a few millimetres behind it. Anything done at that edge, whether a lash lift, a tint or sulam eyeliner (semi-permanent eyeliner), lands very close to the eye. Most people have these treatments without trouble. This piece explains what has been reported to go wrong, what to do first, and when to see a doctor. It is not a judgement on anyone who offers these services.

What can go wrong at the lash line after a lash lift, tint or sulam eyeliner?

The problems reported fall into four groups: irritation or allergy, infection, damage to the eye surface, and, with tattooed eyeliner, changes that stay in the lid for years. The evidence is thin for some of these, so I will say "reported" and not give you a percentage, because the studies do not support one.

Three things make this area unforgiving. The skin of the eyelid is thin. The meibomian glands, the oil glands lined up along the lid edge, open right at the lash line. And the cornea, the clear front window of the eye, is very sensitive, so a small amount of product or a tiny scratch is felt at once. For the wider picture of how lids and lashes go wrong, see my piece on allergic eyelid reactions.

Can a lash tint harm the eyes?

It can, and this is one of the few points where a regulator has been direct. The US Food and Drug Administration (FDA) states that permanent eyelash and eyebrow tints and dyes have been known to cause serious eye injuries, including blindness. It adds that the only colour additive it has provided for in these products is silver nitrate, in professional-use products only, limited to 4 percent in a gel, for no longer than 1 minute, and not for anyone under 16.

Two cautions. First, the FDA is the American regulator, and Malaysian rules are set by our own authorities, so I quote it for what it says about the eye, not as a statement of local law. Second, "serious injury" describes what has been reported, not what usually happens. The point is that a tint sits millimetres from a surface that cannot be replaced.

Tints can also cause an allergic reaction of the lid: itching, redness, swelling and a puffy, sore edge. If one lid swells suddenly, my guide to a suddenly swollen eyelid lists the signs that mean the same day.

Can a lash lift cause an eye infection?

Rarely, but it has been reported. A 2021 case report in the Journal of Cosmetic Dermatology describes a 55-year-old woman who developed swollen, red eyelids in both eyes two days after a cosmetic eyelash lift. Examination showed lid swelling, redness of the eye, chemosis (swelling of the clear tissue over the white of the eye) and mucopurulent discharge. She had no pain and full eye movement. The diagnosis was preseptal cellulitis, infection of the lid in front of the orbital septum, the thin sheet that separates the lid from the socket. Antibiotics by mouth and drops were given, and the signs settled in the first week.

This is one woman, so it tells you a complication is possible, not how often it happens. The authors' conclusions are practical: any blepharitis (inflamed, crusty lid margins) or meibomitis (inflamed oil glands) should be found and treated before the procedure, and lid hygiene and proper sterilisation of equipment matter during it. That is one reason I would want an eye with sore, crusty or recently infected lids to be settled first. Blepharitis is covered here.

If you have lash extensions or lash serums in mind, they are a separate subject, and Retreat's article on lash extensions and serums covers them, so I will not repeat it here.

What are the risks of sulam eyeliner and permanent eyeliner?

Tattooed eyeliner carries the general risks of any tattoo plus some that are specific to the lid. The FDA lists infection (from unsterile equipment or from contaminated ink), allergic reactions, granulomas (small nodules the body forms around pigment it treats as foreign), and keloids (scars that grow beyond their edges) in people prone to them. It also states that no colour additive is approved for injection into the skin.

The lid-specific risk was set out in a 2022 review by Serup in Current Problems in Dermatology: eyeliner tattooing is associated with special complications because of the delicate anatomy and its closeness to the eye, including the risk of meibomian gland damage. The same review lists early problems such as infection, particularly herpes simplex, and late ones such as colour change, pigment spreading into the surrounding skin, nodules, eye irritation and scarring. A 2026 review in the Turkish Journal of Ophthalmology, on dry eye after surgical and cosmetic procedures, names permanent eyeliner tattooing as a source of added risk, especially for people who already have meibomian gland dysfunction or weak tear function. These are reviews of what has been reported, and none gives a rate.

Why it matters: when those glands are lost or blocked, tears evaporate faster, and the eye can feel gritty, tired and watery. That overlaps with the eyelid margin cause of dry eye, and with the reasons eyes look and feel tired, in what makes eyes look tired.

Two more facts to know. The FDA says people with permanent eyeliner should tell the radiologist before an MRI, and that avoiding an MRI your doctor recommended is likely to carry greater risk than the tattoo. Removal is also difficult: the FDA says removing a tattoo is painstaking, usually takes several treatments, and complete removal without scarring may be impossible. For any question about removal, ask a suitably credentialed clinician who has examined your lids.

What should I do first if my eye or lid reacts?

Stop the product, do not apply anything more to that eye, and get the eye looked at if the irritation does not settle. That matches the FDA advice: if any eye cosmetic causes irritation, stop using it immediately, and if the irritation persists, see a doctor. The FDA also says to avoid eye cosmetics while the eye has an infection or the skin around it is inflamed, and to wait until the area has healed.

Beyond that, this is how I would sort the situation. Go the same day for pain in the eye, reduced or blurred vision, a very red eye, sensitivity to light, an eye that does not move fully, a lid that is hot, tender and swollen, or a fever. A stinging, itchy lid without those signs can be seen within a day or two. Please do not rub the eye, and do not try to dig out or scrub off tattoo pigment.

Going back to the person who did the treatment to tell them what happened is reasonable, as is asking what product was used. What they cannot do is examine the inside of your eye, and a doctor can.

How can I lower the risk before booking, in Shah Alam, Puchong or anywhere in the Klang Valley?

Choose a time when your eyes are well, and ask questions first. Wherever you are, from Shah Alam and Subang Jaya to Puchong and Kota Damansara, the checklist is the same:

• Do not book while you have a red, sore, crusty or recently infected lid, or an eye infection.
• Ask what product will be used and whether it is meant for the eye area.
• Ask about clean, single-use tools and hand hygiene, in line with the FDA eye cosmetic checklist, which stresses clean, single-use applicators and clean hands.
• If you have dry eye, blepharitis, a history of lid infections or allergies, or thin lashes from a medical cause, ask an eye doctor first. Lash loss has its own list of causes in eyelash and eyebrow loss in adults.
• Keep the name of the product and the date. It helps any doctor who sees you later.

For the full set of lid conditions, the eyelid conditions hub is the place to start. None of this is a reason to fear the lash line. It is a reason to treat it like the part of the eye it is.
