Day 40 after a lash appointment is an important checkpoint. If you still have extensions left, they may look lighter, more uneven, or less styled than during the first two weeks - and that is normal. Natural lashes shed continuously, and extensions leave with the natural lashes they are attached to. In Batumi, summer humidity, beach days, swimming, sunscreen, and travel plans can make a mature lash set feel especially unpredictable.
I created this day 40 lash aftercare checklist for my clients, tourists, expats, and anyone who is between appointments. The goal is not to make old extensions last forever. It is to keep your natural lashes clean, avoid unnecessary damage, and decide whether you need a fill, a removal, or a fresh set.
What day 40 lashes usually look like
By day 40, most clients have gone beyond the usual fill window. A few extensions may remain beautifully attached, while other areas can look sparse. You may notice more visible gaps, twists, lashes growing in different directions, or a style that no longer looks balanced.
This does not automatically mean your extensions were applied badly. Your natural lash cycle, skincare routine, sleep habits, and time spent in water all affect how a set changes. A humid Black Sea summer can also make you reach for more face mist, sunscreen, cleansing, or swimming - all good habits, but they require careful lash cleaning afterward.
At this point, I do not recommend trying to “save” the look with mascara, strip lashes over extensions, or extra glue. A day 40 set deserves gentle maintenance and an honest assessment.
Your day 40 lash aftercare checklist
Use this checklist in the morning or evening, with clean hands and good lighting:
- Look at both eyes from the front and side. Check whether one side has more gaps, twisting, or grown-out extensions.
- Clean your lash line with a lash-safe, oil-free cleanser or foam. Rinse carefully with water.
- Pat around the eye area dry with a clean, lint-free towel. Do not rub the extensions.
- When the lashes are fully dry, brush them gently from the middle to the tips with a clean spoolie.
- Check for any extension that is attached to a natural lash but has grown far away from the lash line. Do not pull it off.
- Notice comfort: lashes should not feel tight, pokey, sticky, or heavy.
- Decide whether the remaining coverage is suitable for a fill or whether a removal and new set would be more practical.
If you have redness, swelling, ongoing pain, or significant irritation around the eyes, stop using eye products around the area and seek advice from an appropriate healthcare professional. I do not diagnose eye conditions, but discomfort is never something to ignore.
Clean thoroughly, especially after Batumi beach days
Many people think water is the enemy of lash extensions. It is not. Clean water and a correct cleansing routine are part of good aftercare. What causes problems is leaving salt, sunscreen, sweat, makeup, or skin oil around the lash line.
After a walk along Batumi Boulevard, a day at the beach, or time by a hotel pool, wash your face as soon as it is convenient. Pay attention to the base of the extensions, where residue can collect. Use a soft brush made for lash cleansing if you have one, and rinse without pressing or scrubbing.
Sea salt can leave lashes feeling stiff when it dries. Pool water may also leave residue. A gentle wash, rinse, and careful dry is much better than trying to comb through dry, salty lashes. If you wear sunscreen close to the eyes, choose a formula you can apply carefully and cleanse off properly at the end of the day.

Products to use and products to pause
At day 40, it can be tempting to hide gaps with every product in your makeup bag. I recommend keeping your routine simple instead. Lash extensions generally look and feel better when the lash line is clean and free from oily residue.
Helpful choices
- Oil-free lash cleanser or gentle cleansing foam
- Clean spoolie brushes for light daily grooming
- Water-based eye makeup when you choose to wear it
- A clean pillowcase and a soft sleep mask that does not press on the lashes
Choices to avoid on an old set
- Waterproof mascara, especially at the roots
- Oil-based eye makeup remover around extensions
- Mechanical eyelash curlers
- DIY lash glue, cluster lashes, or strip lashes attached over extensions
- Picking, pulling, or trimming extensions at home
Do not use mascara to make a sparse set look full again. Removing mascara often needs more rubbing, and old extensions can tangle more easily. If your lashes need a dramatic refresh for a dinner, photos, or an event, booking the right service is safer than layering products.
Can you still swim, use a sauna, or wear makeup?
Yes, but day 40 is not the moment to be careless. Swimming is fine when you cleanse afterward. For sea and pool days, take a small cleanser or plan to wash your lashes once you return to your apartment or hotel. Do not leave saltwater, chlorine, sweat, and sunscreen on the lash line overnight.
Sauna and steam rooms may make lashes feel damp and can affect how a mature set sits, particularly if you use them frequently. Let the lashes dry naturally after heat and brush only when they are fully dry. Avoid pressing your face into a towel or rubbing your eyes after a steam session.
For makeup, keep eyeliner and shadow away from the extension bases where possible. Powder shadows are often easier to remove than thick cream formulas. If you are travelling with a small makeup bag, pack a lash-safe cleanser before you pack another mascara.
Fill, removal, or a new full set?
The right next appointment depends on how much coverage remains, the state of the grown-out extensions, and your natural lashes. At around day 40, a regular fill is not always the best option. If there are only a few extensions left or many have grown out, removal and a new set may give a cleaner, more comfortable result.
| What you see | What I usually recommend |
|---|---|
| Even coverage remains, with only moderate gaps | Send me a clear photo to check whether a longer fill is suitable. |
| Large gaps, uneven styling, or many grown-out extensions | Consider removal and a fresh full set. |
| Extensions feel uncomfortable, sticky, or tangled | Do not pull them; arrange a professional assessment or removal. |
| You are leaving Batumi soon | Keep them clean, avoid DIY fixes, and plan your next appointment at your destination if needed. |
Different styles also age differently. A classic set can look naturally soft as it sheds, while a fuller 2D, 3D, or mega volume set may show gaps more clearly once the fans have shed. If you are choosing your next look, you can compare options through my lash extension style information.
Common day 40 mistakes I see
The most common mistake is waiting too long and then trying to repair the set at home. I understand the reason: you may be busy, travelling, or hoping to get a few more days from your lashes. But a few remaining extensions are not a reason to start pulling, gluing, or cutting.
Another mistake is skipping cleansing because there are not many lashes left. The lash line still needs to be clean. Natural lashes, skin oil, makeup, and environmental residue do not disappear when extensions shed.
I also see clients brush too aggressively. A spoolie is for gentle alignment, not for forcing twisted or grown-out extensions back into place. If an extension is hanging low or rotating, leave it alone and let a professional remove it safely.
A simple routine until your appointment
Until you can book, keep your routine consistent:
- Clean the lash line once daily, and after swimming or heavy sweating.
- Dry gently and brush only after the lashes are dry.
- Sleep without crushing your face into the pillow when possible.
- Skip mascara, curlers, oils, and DIY additions.
- Take a clear photo in daylight if you are unsure whether you need a fill or removal.
If you are in Batumi for only a few days, message before you arrive or as soon as you know your schedule. Tourist weeks fill quickly in summer, and a photo helps me suggest the most realistic appointment length. You can also check my current lash extension prices before booking.
Conclusion
Day 40 lashes do not need panic or home repairs. Clean them well, protect your natural lashes, and be realistic about the coverage that remains. For many clients, this is the right time to plan a refresh rather than stretch the old set further.

FAQs
- Is day 40 too late for a lash fill?
It can be. If enough healthy, well-positioned extensions remain, a longer fill may be possible. If the set is very sparse or has many grown-out extensions, a removal and new set is usually a cleaner option.
- Can I remove a few loose-looking extensions myself?
No. An extension may still be attached to a natural lash even when it looks grown out. Pulling can remove or stress the natural lash. Leave it for professional removal.
- Does swimming in the Black Sea ruin lash extensions?
Swimming itself does not automatically ruin them. The important part is rinsing and cleansing away saltwater, sunscreen, sweat, and other residue afterward.
- Why do my extensions look uneven after several weeks?
Natural lashes do not all shed at the same time. As different natural lashes complete their own cycles, the extensions attached to them shed too. Sleeping position, skincare, and daily habits can also make one side look lighter.
