- Sensitive eyes or skin: TALIKA Lipocils Expert or LASHFOOD Phyto-Medic. Both are described by the brands as prostaglandin-free.
- Wearing lash extensions: an oil-free serum such as MW Lash Serum (฿1,999), plus a sealing gel such as PHENIX EYE (฿1,490).
- Thin eyebrows: RapidBrow (฿2,495), or MW Lash Serum / Nano Crysphere, which work on both lashes and brows.
- After a lash lift: Procare Eyelash & Eyebrow Keratin (฿990).
What causes thin lashes, lash shedding and sparse brows?
First work out whether the cause is natural lash biology or a habit that damages lashes, because the fixes differ. A lash grows an average of 0.12 mm per day, so it takes several weeks before new lashes are visible.
About biotin: a 2017 review found biotin helps hair and nails only in people who are actually deficient. Do not expect biotin alone to lengthen lashes; look at the full formula and how you use it.
The short natural lash cycle. Losing a few lashes a day is normal. Plucked lashes typically regrow in about 8 weeks.
Heavy extensions or forceful removal. Constant pulling can cause traction alopecia.
Rubbing eyes or harsh makeup removal. Especially with waterproof mascara, this breaks or pulls out lashes early.
Eyelid inflammation or general health. Demodex mites, allergies, thyroid problems or poor nutrition can thin lashes. See a doctor if shedding is unusually fast.

Lash serums follow two approaches. Growth-boosting formulas contain a prostaglandin-class ingredient that prolongs the lash growth phase. Conditioning formulas based on plants and peptides aim to make lashes stronger and more hydrated in a gentle way. Choose by your goal and your comfort level.
Products in this guide, by formula
- Growth-boosting: RapidLash and RapidBrow (the US formula label lists isopropyl cloprostenate)
- Plant and peptide, prostaglandin-free: Talika, LashFood and MW Lash Serum
- Conditioning: Nano Crysphere (10-Free)
What to know about growth-boosting formulas
- This ingredient class is related to glaucoma eye drops
- Some users report red eyes, irritation or darkening of the skin around the eyes
- A 2022 study in Aesthetic Surgery Journal examined periocular fat changes, and France's ANSES has warned about iris colour change
- Most effects improve after stopping. If you are interested, staff can explain how to use it.
Talk to a doctor before starting if you
- Are pregnant, breastfeeding or treated for an eye condition such as glaucoma
- Have dry eye, eyelid inflammation, a stye or recent eye-area surgery
- Have previously reacted to eye-area cosmetics
Tips for better results
- Apply a thin line at the upper lash line, never on the eyelid
- Use one product at a time so you can tell what works
- Take a photo before you start and compare every 4 weeks
- If you get redness, stinging or swelling, stop and see a doctor
How to use lash serum effectively and safely
Always follow each product's label. The general method is:
Cleanse and remove all makeup. Wait until skin is dry.
Apply a thin line at the upper lash line like eyeliner, from inner to outer corner. Keep it out of the eye.
Let it dry for 1–2 minutes before applying other skincare.
Use consistently for at least 8 weeks. Results vary from person to person.
Don't rub or pull your lashes. If you get redness, stinging or swelling, stop and see a doctor.

- NightApply lash serum at the upper lash line and brow serum along the brows

Frequently asked questions about lash and brow serums
Which eyelash serum is best?
It depends on your goal and your comfort with ingredients. For longer, more curled, darker lashes, try Talika Lipocils Expert or RapidLash. For sensitive skin, Talika and LashFood are described by the brands as prostaglandin-free. If you wear lash extensions, choose an oil-free serum such as MW Lash Serum. Use the filters in Choose by category.
How long does a lash growth serum take to work?
Most serums need 4–8 weeks of consistent use, because lashes grow about 0.12 mm per day and have a life cycle of roughly 90 days. Results vary from person to person.
Can a serum stop eyelash loss?
Shedding a few lashes is normal. A serum can help lashes look stronger but is not a treatment for disease. If loss is unusually heavy, or you have red, swollen, itchy lids or bald patches, see an eye doctor or dermatologist.
What is the difference between growth-boosting and conditioning lash serums?
Growth-boosting formulas contain a prostaglandin-class ingredient that prolongs the lash growth phase and have some reported side effects. Conditioning formulas based on plant extracts and peptides suit people who prefer a gentle, long-term routine. See more details.
How is a lash sealing gel different from a lash serum?
Serums are applied at the lash line and used over weeks to condition the lash. Sealing gels coat the lash itself to keep lashes in shape and protect against dust, sweat and oil. Use serum at night and gel in the morning before makeup.
How do I care for lashes after extensions or a lash lift?
Avoid rubbing or pulling lashes, brush them each morning, use a suitable coating gel or keratin, choose an oil-free serum if you wear extensions, and follow your technician's advice. Stop use and see a doctor if eyes become red, sore or swollen.
