Scientific Analysis and Purchase Guide of Eyelash Growth Liquid

Long eyelashes can make eyes more vivid, but what should I do if my eyelashes are short, sparse or easy to fall off? Various eyelash growth liquids on the market claim to be "effective in 7 days" and "naturally thick", but are they really effective?
Yunmei will combine scientific basis + ingredient analysis to reveal the truth about eyelash growth serum for you and provide a safe purchase guide.

Is Eyelash Growth Serum Really Effective?
1. Scientific principle: eyelash growth cycle
Like hair, eyelashes have their own growth cycle:
Growth period (4-6 weeks): eyelashes grow actively.
Degeneration period (2-3 weeks): growth stops and hair follicles atrophy.
Resting period (3-4 months): eyelashes fall off and new eyelashes begin to grow.
The role of eyelash growth liquid: extend the growth period and activate dormant hair follicles through active ingredients to make eyelashes thicker and longer.

2. Which ingredients are really effective?
Peptide: Promotes keratin production and enhances eyelash toughness; mild, suitable for sensitive skin
Biotin: Improves hair health, but requires long-term use; oral administration is also effective
Plant extracts (ginseng, Polygonum multiflorum, etc.): nourish hair follicles, mild but slow to take effect, need to persist for three months;

 How to Choose Safe and Effective Eyelash Growth Liquid?
1. Look at the ingredients
Prioritize : peptides, biotin, plant essences (such as green tea extract).
Avoid: containing preservatives (phenoxyethanol), alcohol, hormone ingredients.

2. Brand qualifications
Choose a brand with "FDA certification" or "clinical test report".
Avoid three-no products, especially micro-businesses and low-priced "fast-acting" products, and choose products from professional and qualified manufacturers.

Correct Use Method & Precautions
1. Correct application method
Steps:
Clean the eyes to ensure that there is no makeup residue.
Use the brush head to lightly apply along the root of the eyelashes (similar to drawing eyeliner) to avoid getting into the eyes.
Use once a night for 8-12 weeks of continuous use to see results.

2. Possible side effects
Mild irritation, red blood streaks (recovery upon discontinuation of use).
Pigmentation around the eyes (more common with bimatoprost products).

Is Eyelash Growth Serum Worth Buying?
It is effective, but you need to choose the right ingredients: peptides and biotin are safer, and bimatoprost is more effective but requires caution.
Time to see results: Generally, changes can be seen in 4-8 weeks, and the best effect is 3 months.
Not suitable for everyone: People with sensitive skin and eye diseases are recommended to consult a doctor.

What to Consider When Customizing a Private lableEyelash Growth Serum?

As a precise repair-type beauty product, eyelash growth serum needs to balance safety, efficacy, and user experience. Combining its product characteristics with the entire customization process, nine core issues need to be addressed to create a competitive, market-demand-driven product:

1. Eyelash Growth Serum Price
The price of eyelash growth serum is concentrated on active ingredients, such as biotin, panthenol, and peptides. High-purity raw materials have a higher unit price. A gentle formula base is necessary to avoid irritating the eye area mucosa, requiring the use of medical-grade solvents. Packaging costs, such as light-proof dropper bottles and aseptic filling processes, also need to be considered. The cost per bottle must be calculated in advance to avoid pricing exceeding the target customer's affordability due to ingredient upgrades.

2. Eyelash Growth Serum Ingredients
Select ingredients based on core needs. For basic growth, choose biotin (strengthening eyelashes and reducing shedding) and panthenol (deeply nourishing and improving roughness). For advanced growth, choose peptides (such as myristoyl pentapeptide). 17. Stimulates hair follicle activity), plant extracts (such as ginseng and rosemary, gently promoting growth);

3. Product Types
Texture Type: Daily use: Choose a refreshing serum-like consistency, easily absorbed, non-sticky to eyelashes, suitable for use before makeup; Night Repair: Choose a thick serum-like consistency, containing high concentrations of nourishing ingredients, suitable for thick application before bed, will not affect sleep;
Function Type: Targeted needs – Fast Growth Formula: Contains high concentrations of peptides, suitable for those with sparse eyelashes; Strengthening and Repair Formula: Contains biotin + squalane, suitable for damaged eyelashes after perming and dyeing; Waterproof and Long-Lasting Formula: Contains film-forming agents, suitable for summer or those prone to sweating, prevents smudging when used with mascara.

4. Packaging Design

Practicality Design: Prioritize narrow-tipped dropper bottles for precise dosage control and to prevent spillage around the eyes; soft silicone brush heads are recommended to avoid pulling on eyelashes; avoid wide-mouthed bottles as they are prone to contamination and oxidation, increasing the risk of bacterial infection; large-capacity bottles can feature a pump dispenser with a resealable cap for both hygiene and convenience.

Light Protection Design: Active ingredients, such as peptides and plant extracts, are easily degraded by light; therefore, the bottle should be made of opaque materials such as brown glass or light-blocking PET, or paired with a light-proof outer box to extend the product's shelf life.

5. Transportation

Sea Freight: Suitable for large quantities and non-urgent orders; low cost but long delivery time (15-45 days). Bottles must be wrapped in shock-absorbing foam to prevent breakage during transport.

Air Freight: Suitable for small trial orders and urgent replenishment; fast delivery time (3-7 days). Simplified packaging (e.g., removing excess outer boxes) is necessary to control weight. The outer box should be marked "Fragile" and "Protect from Light" to remind the logistics company to handle with care.

Land Transportation: Suitable for short-distance delivery within China or neighboring countries (e.g., self-delivery for cross-border e-commerce), with moderate delivery time (1-5 days). Regular express delivery is available.

6. Compliance

Ingredient Compliance: Complies with target market regulations for eye care products (e.g., China GB/T 35914-2018 "Cosmetic Safety Technical Specifications", EU EC 1223/2009), and does not use prohibited growth-promoting ingredients (e.g., minoxidil, limited to pharmaceutical use only, prohibited from addition to cosmetics); imported ingredients require customs declarations and quality inspection reports.

Label Compliance: Packaging must include warnings such as "for eye use only" and "avoid contact with eyes." The ingredient list must be ordered according to INCI standards. Exported products must also include foreign language instructions (e.g., English usage instructions, contraindications); if claims of "growth" or "strengthening" effects are made, third-party efficacy testing reports (e.g., data on changes in eyelash length and density) must be provided.

7. Brand Positioning

Target Customer Matching: For pregnant women and those with sensitive skin, we offer a gentle formula that is fragrance-free, preservative-free, and non-irritating; for beauty enthusiasts, we offer a 2-in-1 eyelash growth and base product.

Differentiated Highlights: We design exclusive selling points, such as customized brush heads (with thin and wide heads to suit different eyelash distributions), customized fragrances (adding light woody and floral notes to enhance the user experience), and eco-friendly packaging (biodegradable bottle + replaceable refills to attract environmentally conscious customers).

8. User Experience

Brush Head Fit: The brush head length and firmness must conform to the curvature of the lash line – a short brush head is suitable for fine lashes at the inner and outer corners of the eyes, while a long brush head is suitable for the middle of the lashes; a soft silicone brush head is gentler than a hard plastic brush head, reducing pulling on the lashes.

9. After-Sales Service

Sample Testing: A small sample will be provided before customization, offering a 7-day trial pack to test lash irritation, drying speed, and ease of use. The formula will be adjusted based on feedback (e.g., reducing ingredient concentration, optimizing brush head design).

After-Sales Support: Usage instructions will be provided, such as applying once in the morning and once in the evening, avoiding the eyelid mucosa. For leakage or packaging damage during transportation, unconditional reshipment is promised. User feedback on lash growth will be collected for subsequent formula optimization, and bulk customization discounts will be offered to long-term clients.
