Lash extensions are, in my experience, one of those things people think requires more effort than it does and in one specific area, considerably less effort than people think. If you're considering lash extensions at our Auckland North Shore studio, here's everything you need to know about aftercare.
The truth is that lash extension aftercare and caring for your lash extensions is straightforward once you understand why each step matters. This guide covers everything you need to know, from the first 24 hours through to your next infill.
The First 24 Hours: The Most Important Window
In the first 24 hours after your appointment, the adhesive is still curing. During this window, the bond is vulnerable to moisture and heat. I ask all clients to keep their lashes completely dry, no washing the face around the eye area, no steam rooms, no heavy exercise that would cause significant sweating around the face.
This single step has the biggest impact on retention. Clients who are careful in the first 24 hours consistently find their extensions last longer and hold better throughout the cycle.
Cleansing: The Step Most People Skip
This surprises many clients, but clean lashes last longer than dirty ones. Product buildup at the lash line from makeup, skincare, and daily life weakens the adhesive bond over time and creates an environment for bacteria, which can cause irritation and lash loss.
I recommend cleansing the lashes every second day using a gentle, oil-free lash cleanser and a soft cleansing brush. Apply the cleanser, brush gently through the lashes in a downward motion, then rinse with water and pat dry. Never rub.
If you wear eye makeup, remove it first with an oil-free micellar water on a cotton pad, working carefully around the lash line without dragging the extensions.
What to Avoid
•Oil-based products near the eyes
Oil breaks down the adhesive bond faster than anything else. Check the ingredients of your moisturiser, eye cream, makeup remover, and any serums applied near the eye area. Switch to oil-free alternatives during your lash extension cycle.
•Mascara
Standard mascara is not recommended on extensions. Waterproof formulas are particularly damaging as they require oil-based removers to take off. If you want more definition on your lower lashes, a non-waterproof, water-based mascara is acceptable — but extensions on their own should already be doing the work.
• Rubbing or pulling
This is the fastest way to damage both the extensions and the natural lashes underneath. If an extension feels uncomfortable or is sitting at an odd angle, come back and I'll look at it. Do not attempt to remove it yourself.
• Steam and heat
Saunas, steam rooms, and very hot showers soften the adhesive over time. Try to direct heat away from the face and limit exposure where possible.
• Sleeping face-down
Friction from pillowcases overnight can gradually pull at the extensions. A silk or satin pillowcase makes a significant difference, the smooth surface creates far less friction than cotton.
• Aftercare coating serum
This is one of the best things you can do to keep your natural lashes healthy between appointments. The Eye d'or Essence Gloss Coating Serum is a Japanese-made treatment that works as both a protective coating and a nourishing serum. Apply it in the morning to brush and set your extensions, or at night to repair and condition your lashes while you sleep. Think of it as a hair treatment, but for your lashes.
Products Worth Using
A lash sealant applied every few days adds a protective coating over the adhesive bond and can meaningfully extend retention. Ask me at your appointment and I can recommend one suited to your lash type.
A lash growth serum applied to the roots (not the extensions themselves) supports the health of your natural lashes in between appointments. Healthy natural lashes hold extensions better and shed less frequently.
When to Come Back
Most clients at En Beauty book their infill appointment at the time of their full set. I recommend every three weeks for optimum results. If you're coming up to three weeks and your lashes are still looking full, you may be able to stretch to four weeks. Beyond that, you risk losing enough natural lashes that a full new set becomes more practical.
If you notice significant gapping, or if an extension is irritating you, please don't wait for your scheduled appointment. Come in and I'll sort it.
