Your Aftercare Tips
Avoid Water for 24 Hours
Following your treatment, please avoid washing your face with hot water or getting your lashes wet for a minimum of 12–24 hours. Do not swim, use a bath steam or sauna, or undertake strenuous activities that may cause your eyes to come into contact with water.
No Mascara
Do not use regular or waterproof mascara. These products contain oily substances that cause the adhesive to weaken and, in turn, cause your eyelash extensions to fall off prematurely. Your extensions provide all the definition and length you need — mascara is unnecessary.
Avoid Oil-Based Products
Oil-based products — including makeup removers, cleansers, and moisturisers — break down the lash adhesive and shorten the life of your extensions significantly. Always choose oil-free formulas for any product used around the eye area.
Book Regular Infills
Lash extensions typically last up to 4 weeks. We recommend scheduling an infill every 2–3 weeks to keep your set looking full and fresh. Regular infills replace any lost extensions as natural lashes shed throughout their growth cycle.
Handle with Care
Avoid rubbing, touching, or pulling at your extensions. Rough handling causes premature shedding and can damage your natural lashes. When drying your face, gently pat — never rub — the eye area with a clean, soft towel.
Arrive Prepared
For the best results, arrive with clean, makeup-free lashes. Remove all eye makeup and contact lenses before your appointment. Avoid oil-based products around the eyes in the days prior, and do not curl your natural lashes beforehand.
What You Need to Know
How Long Do Extensions Last?
With proper aftercare, lash extensions last up to 4 weeks. Because natural lashes shed as part of their growth cycle, you will gradually lose extensions over time. Regular infills every 2–3 weeks keep your set consistently full and fresh.
Premium Materials, Safe Application
At I Heart Lashes, we use only the finest silk and mink lash extensions with medical-grade adhesive. Each extension is individually placed on a single isolated natural lash — never glued to the skin — ensuring a safe, comfortable result every time.

Aftercare FAQs
Can I wear eye makeup with lash extensions?
You can wear eye shadow and liner, but avoid mascara — especially waterproof formulas — and all oil-based products around the eye area. Use oil-free makeup removers and apply products carefully to avoid the lash line.
Why do I need to avoid water for 24 hours?
The lash adhesive needs time to fully cure after application. Exposure to water, steam, or humidity during this window can weaken the bond and cause premature shedding. Keeping lashes dry for 12–24 hours ensures the best possible retention.
What happens if I don’t get regular infills?
Without regular infills, extensions will shed as natural lashes go through their growth cycle. After 4–6 weeks without an infill the set may look patchy or sparse. Infills every 2–3 weeks keep the look consistently full.
Are lash extensions safe for my natural lashes?
Yes — when applied correctly by a trained professional, lash extensions are entirely safe. At I Heart Lashes, each extension is placed on a single isolated natural lash with medical-grade adhesive. Proper aftercare protects your natural lashes throughout.
