Lash Lift Contraindications, Patch Testing and Safety

Course: Lash lift and brow lamination course from A to Z · Module 4 of 8

A technically perfect lift can still go wrong if it’s done on the wrong person or without the right precautions. This module covers lash lift contraindications (and those for brow lamination), how to run the consultation, the patch test, the client record card, workstation hygiene and – most importantly – protecting the eye and knowing what to do if something goes wrong.

Module objectives

Carry out a thorough, documented pre-treatment consultation.
Recognise when not to treat, and when to refer to a healthcare professional.
Understand what a patch test is for, and its limits.
Apply hygiene and eye-protection measures during the service.
Know how to respond if product gets into the eye.

The consultation

The California Board of Barbering and Cosmetology recommends discussing the process, expectations and aftercare with the client before the service. This is where you confirm that a lift or lamination is right for them and pick up any reason not to go ahead. A useful consultation covers at least the following:

Do you currently have any discomfort, infection, stye, conjunctivitis (pink eye) or inflammation of the eyes or eyelids?
Have you had eye or eyelid surgery recently (laser, cataract, blepharoplasty)?
Do you have chronic dry eye, blepharitis or another diagnosed eye condition?
Have you ever reacted to hair or lash dye, perms or other cosmetics?
Do you have eczema, dermatitis, rosacea or very sensitive skin in the area?
Do you use retinol or other exfoliating products around your eyes or brows?
Do you wear contact lenses? (They must come out before the service.)
Have you recently had a lift, lamination, tint or semi-permanent make-up in the area?
Are you pregnant or breastfeeding? Are you taking any medication?

As well as asking, look. The California Board says to examine the eye area for redness, swelling, irritation, recent permanent make-up and any other contraindications listed by the manufacturer and insurer – and not to perform the service if any are present.

Lash lift contraindications and precautions

There’s no single official, closed list – each manufacturer includes its own in the leaflet. The table below brings together the situations cited by health and professional sources. If in doubt, don’t treat, and suggest the client checks with their GP or optometrist/ophthalmologist.

Situation	What to do	Source
Active eye infection or inflammation: conjunctivitis, stye, blepharitis	Don’t treat. Refer to a healthcare professional	ReFocus Eye Health; Healthline
Visible redness, swelling or irritation in the area	Don’t treat	California Board
Recent permanent make-up in the area	Don’t treat	California Board
Recent eye or eyelid surgery	Don’t treat without medical clearance. One eye clinic suggests waiting 3 to 6 months	ReFocus Eye Health
Chronic dry eye	Caution; consider medical advice first	ReFocus Eye Health; Healthline
Known allergy to dyes (especially PPD) or perms	Extreme caution, particularly if tinting as well	ReFocus Eye Health
Sensitive skin, eczema, contact dermatitis, rosacea	May not be suitable; dermatology advice	Medical News Today
Retinol use around the eyes	Stop 3–5 days beforehand, especially before brow lamination	California Board
Pregnancy or breastfeeding	Some sources advise avoiding it as a precaution	ReFocus Eye Health

A case report in the Journal of Cosmetic Dermatology (Mangan and Imamoglu, 2021) describes preseptal cellulitis – an infection of the eyelid tissues – two days after a lash lift. The authors conclude that blepharitis or inflammation of the eyelid glands should be identified and treated before the procedure, eyelid hygiene maintained and proper sterilisation ensured. It’s described as a rare complication, but it shows why you never work on an inflamed eyelid.

The patch test

A patch (sensitivity) test aims to pick up a reaction to the products before the service. The California Board says to carry it out according to the manufacturer’s protocol, noting that patch tests are typically done 48–72 hours before the appointment. It also says to follow your insurer’s requirements and to refer the client to their doctor if any reaction occurs, whether from the test or the service itself.

Healthline describes applying a small amount to a discreet area such as the inner elbow and waiting two days. But it adds an important caveat: the eye area is usually far more sensitive than the rest of the body, so a clear patch test doesn’t guarantee there won’t be a reaction. Make sure the client understands this.

Organising the test, step by step

Check the leaflet: which products to test, where to apply them and how far in advance.
Check your liability insurer’s requirements too, including how often to repeat the test for regular clients.
Carry out the test following that protocol and tell the client which signs to watch for (itching, redness, swelling, blistering).
Record the date, time, product, batch number and test site on the record card and ask the client to sign it.
On the day, ask about the result and check the area. If there’s been a reaction, don’t treat, and recommend the client sees a healthcare professional.

Client record card and consent

The record card is your evidence that the consultation took place and of what was applied. Include contact details, consultation answers, the patch test result, products and batch numbers used, processing times, notes, and the client’s signature confirming they agree to the service after receiving the information.

Bear in mind that allergies, eye conditions or pregnancy are data concerning health – a special category of personal data under Article 9 of the EU General Data Protection Regulation (GDPR; the UK has an equivalent). Store record cards securely, and if you’re unsure how to collect and keep them, check your national data protection authority’s guidance or ask a data protection professional.

Workstation and tool hygiene

Hands and gloves. Wash your hands before every service (California Board). Wear gloves – it’s a condition of use for thioglycolate lash lotions under Annex III of Regulation (EC) No 1223/2009.
Single-use items. Micro brushes, cotton buds and disposable wands – one set per client. Never put a used applicator back into a product.
Shields. Single-use, or – if the manufacturer allows reuse – cleaned and disinfected according to its protocol.
Surfaces and linen. Couch, pillow and work surface cleaned and disinfected between clients.
A clean treatment area. Gently remove make-up, dirt and oil before the service, without exfoliating products or techniques (California Board).
Local rules. Hygiene and licensing requirements for beauty businesses vary by country and region – check what applies where you work.

For disposables such as micro brushes and spoolies, see our accessories category; lash lift systems are in lamination.

Protecting the eye during the service

The US FDA reminds consumers that the eyelids are delicate and that an allergic reaction, irritation or other injury around the eye can be particularly troublesome. That’s why EU law makes “avoid contact with eyes” a condition of use for these lotions. In practice, the California Board recommends:

Confirming the client has removed their contact lenses before you start.
Reminding them to keep their eyes closed and avoid moving, talking and other distractions during the service.
Having sterile water or saline to hand in case the eyes need flushing.
Using only products formulated for lashes or brows, and removing and neutralising all product according to the manufacturer.

Add to that the minimum amount of product, applied with a micro brush and always as the manufacturer directs, and protection of the lower lashes with pads or tape (covered in Module 5).

If product gets into the eye

Stop the service immediately.
Remove contact lenses if present.
Flush the eye with plenty of clean water: the NHS advises running lots of water over the eyeball for at least 20 minutes, with a gentle flow.
Ask the client not to rub the eye.
Get medical help and take the product container with you, as the label can help with treatment (NHS). Severe pain, changes in vision, facial swelling or difficulty breathing are an emergency (ReFocus Eye Health) – call the emergency services (112 in the EU, 999 in the UK).
Record what happened on the client’s card.

In Spain, professional users of cosmetics such as beauty therapists can voluntarily report undesirable effects to the Spanish medicines agency (AEMPS) through its NotificaCS portal. If you work elsewhere, check your national cosmetovigilance or product safety reporting route.

Common mistakes

Skipping the consultation with regulars. Their health or medication may have changed.
Treating a clear patch test as a guarantee. The eyelid is more sensitive than the elbow.
Working on a red or irritated eye “because the client’s in a hurry”.
Not having saline ready before opening the lotions.
Letting the client talk or open their eyes while the lotions are processing.
Not keeping records. Without a card you can’t show what was done or fine-tune the next appointment.

Module summary

The consultation combines questions with a visual check; signs of infection or irritation mean no treatment.
Patch tests follow the manufacturer and insurer, typically 48–72 hours ahead, and are not an absolute guarantee.
The record card holds consultation, patch test, products, batches, timings and consent – and contains protected health data.
Gloves, disposables, lenses out, eyes closed and saline to hand are the basics.
If product gets in the eye: flush with plenty of water for at least 20 minutes and seek medical help.

Self-assessment

1. A client arrives with a reddened eyelid and says it’s “just hay fever”. What do you do?

You don’t treat. Visible redness, swelling or irritation are reasons not to go ahead, and you suggest they see a healthcare professional.

2. How far in advance should the patch test be done?

As the manufacturer specifies and your insurer requires. For reference, the California Board notes it’s typically 48–72 hours before the appointment.

3. Why doesn’t a clear patch test guarantee there’ll be no reaction?

Because the eye area is much more sensitive than the usual test site, such as the inner elbow.

4. Name three eye-protection measures the California Board recommends.

For example: confirming contact lenses are out, asking the client to keep their eyes closed without moving or talking, and having sterile water or saline ready for emergency flushing.

5. What do you do if lotion gets into the client’s eye?

Stop the service, remove any contact lenses, flush with plenty of water for at least 20 minutes, stop them rubbing it and get medical help, taking the product container with you.
