1. | What makes a good eyelash serum?

A good eyelash serum does more than just nourish. It actively stimulates the growth phase of your eyelashes, strengthens the hair structure, and prevents premature loss. However, the quality varies greatly between brands.

At Syrene, we evaluate eyelash serums based on six criteria.

Criterion

What to look for

Goal: What does the serum aim to achieve: length, volume, color intensity, or all of the above?

Effectiveness: Is there a measurable effect within 4–8 weeks?

Safety: Is the product hypoallergenic and tested for sensitive eyes?

Ingredients: Does it contain proven active ingredients?

Ease of use: Simple, precise application and quick-drying formula.

Price/value: Is the ratio between effect, content, and price right?

2. | How do you know if an eyelash serum works?

With an eyelash serum, you can expect the following results:

  • Longer eyelashes
  • More volume
  • Darker eyelashes
  • Stronger eyelashes with more resilience

Effective serums show results with consistent use, usually within 4–8 weeks. It is useful to take a few photos at the beginning so that you can track the results. With Superlash, you receive an eyelash measurement card, which you can use to track your progress.

Superlash users notice a visible difference after an average of 4 weeks, with maximum hair growth around 12-16 weeks.

Promises of quick results can be risky. Some high-dose formulas produce rapid effects but increase the risk of side effects. They stress and strain the hair follicle and the skin around the eye. Therefore, choose a serum that is safe for both short- and long-term use.

3. | The best eyelash serum is transparent

The skin around your eyes is extremely thin and sensitive. Therefore, always choose a hypoallergenic eyelash serum.

Safety guidelines for the best choice:

  • Avoid serums with heavy oils (can affect extensions or lenses).
  • Choose a water-based formula with a controlled dosage.
  • Look for transparent ingredient lists, not vague "growth complexes" or peptides with a ™ without substantiation.

SuperLash is water-based and tested for daily use on sensitive eyes. The formula is free from perfume, parabens, and oils. This makes it safe for use with both eyelash extensions and contact lenses.

3.1 | Choose brands that are transparent about how their products work and their risks

Reliable brands share not only their results, but also their potential side effects.

Syrene and SuperLash believe in openness: every formula has been carefully tested, with clear communication about effectiveness, ingredients, and skin tolerance. Transparency creates trust, and that is the basis of true beauty.

4. | Which ingredients make the difference?

A good eyelash serum combines scientifically proven growth factors with nourishing ingredients.

The main ingredients:

Prostaglandin analogues
Extend the growth phase of the eyelash cycle, making eyelashes longer before they fall out.

Peptides
Strengthen the hair structure and stimulate keratin production.

Botanical extracts
Improve blood circulation and nourish the hair follicles.

Vitamins and antioxidants
Protect against breakage and enhance natural shine.

Why SuperLash stands out Ecuri SuperLash combines prostaglandin analogues, peptides, and growth factors in a carefully balanced dosage. The formula has been refined over several years for maximum effectiveness, safety, and long-lasting eyelash lift.

5. | How important is ease of use?

A serum only works if you continue to use it daily. Ease of use therefore determines its ultimate success.

Look for:

  • A thin, precise applicator that applies the right amount.
  • A quick-drying formula so it doesn't run into your eyes.
  • Enough content (at least 3 ml) to use consistently for 10–12 weeks.

6. | Is more expensive always better?

Not necessarily. The price of an eyelash serum means little without context. Pay more attention to ingredients, dosage, and independent evidence than to branding or packaging.

A serum with proven active ingredients such as prostaglandin analogues and peptides may work better than an expensive product with marketing claims. Value lies in effectiveness, not luxury.

A reliable serum is backed by transparency and positive experiences. Look for independent reviews and experiences from real users.

Superlash:

  • Countless positive reviews over the years on various websites
  • Independently tested on beauty platform WeAreEves: 250 women, average score 4.1 stars
