What is eyelash serum with prostaglandin?

Prostaglandin analogues are synthetic substances that mimic the natural prostaglandins in the body. They were originally used in the medical world, particularly in eye drops for glaucoma. While using these, users discovered an interesting side effect: their eyelashes grew longer and fuller. This led to the development of eyelash serums containing these ingredients to specifically stimulate eyelash growth.

How does eyelash serum with prostaglandin work?

The effect of eyelash serum with prostaglandin is based on prolonging the growth phase (anagen phase) of the eyelashes. Normally, eyelashes grow for a certain period of time before they fall out and make way for new hairs. Prostaglandin analogues prolong this growth phase, causing the eyelashes to grow for longer before they fall out. This results in longer, fuller and stronger eyelashes. They also stimulate the hair follicles and make the eyelash hairs darker, which can provide extra volume and density.

Are eyelash serums with prostaglandin safe?

A frequently asked question is whether an eyelash serum with prostaglandin is safe. In general, these serums are safe when used correctly. They have been dermatologically and ophthalmologically tested, which means that they are suitable for the sensitive skin around the eyes. Possible side effects, such as slight redness or irritation, are usually temporary and disappear as soon as use is discontinued. It is important to follow the instructions for use and not to apply the serum excessively.

3.1 | Possible side effects

Some people experience slight redness, dryness or tingling, usually with overuse or sensitivity. These reactions usually disappear on their own when use is discontinued.Therefore, always follow the instructions for use: one thin line along the upper lash line is sufficient. Here, 1 dip is enough for both eyes.

6. | When is an eyelash serum containing prostaglandin less suitable?

Be careful in the following situations:

  • If you have very sensitive eyes or allergies.
  • If you already use eye drops containing prostaglandin.
  • During pregnancy or breastfeeding, as a precaution.

What are the benefits of eyelash serum with prostaglandin?

  • Fast and visible results: The first effects are noticeable within 4 to 8 weeks.
  • Longer growth phase: lashes are given more time to grow before they fall out.
  • Thicker and fuller appearance: more hairs can remain in the growth phase at the same time and they are made darker.
  • Easy to use: applying only once a day to the lash line is sufficient.

Are there alternatives to prostaglandin?

For people who prefer to use an alternative, there are also prostaglandin-free eyelash serums. These often contain peptides, biotin and botanical extracts that nourish and strengthen the eyelashes. Although these serums are less powerful than prostaglandin analogues, they can still contribute to healthier and fuller eyelash growth.

5.1 | "It's hormones."

Incorrect. Prostaglandin analogues are not hormones, but synthetic compounds that resemble the body's own fatty acids. They mimic a local signaling mechanism but do not affect hormonal balance. There is no scientific evidence that cosmetic serums containing prostaglandin analogues have a systemic hormonal effect.

5.2 | "They can disrupt your hormone balance."

An understandable concern, but not based on fact. Cosmetic eyelash serums are applied locally along the lash line, not ingested or dripped into the eye as in medicinal applications. As a result, the active ingredient remains superficial and locally active. There is no indication that this application affects estrogen, progesterone or other hormonal systems.

5.3 | "They change your eye color."

This effect has only been observed with medical eye drops containing high concentrations of bimatoprost, applied daily to the eye. Cosmetic serums contain considerably lower doses and are not brought into direct contact with the iris. The risk of discoloration is thus practically eliminated.

5.4 | "Your eyelashes get used to it."

Incorrect. When you stop using them, your lashes return to their natural growth cycle, with no lasting changes.


In short: prostaglandin analogues are safe AND effective, if applied as intended.

7. | What are the alternatives?

Those who prefer an eyelash serum without hormones can choose from several formulas with natural, nurturing ingredients. These serums do not focus on stimulating new hair growth as prostaglandin analogues do , but rather on strengthening, protecting and nourishing existing eyelash hairs. They improve the condition of lashes, making them look healthier, fuller and shinier

7.1 | Peptides

Support the hair structure and help anchor lashes more firmly into the skin. They promote a healthy growth cycle, but do not stimulate additional hair growth.

7.2 | Biotin (Vitamin B7)

Nourishes eyelash hairs from within and prevents them from becoming brittle or fragile. Biotin contributes to stronger, more resilient lashes.

7.3 | Hyaluronic acid

Keeps lashes hydrated and supple, making them less likely to dry out or break off. It strengthens the hair's natural elasticity.

7.4 | Castor oil

Known for its nourishing and emollient properties. Castor oil coats each lash with a protective layer, contributing to a healthy, glossy appearance.


Although these ingredients have no hair growth-active effect, they provide a gentle, nurturing base for those who want to maintain healthy, natural lashes , without the use of hormonal or prostaglandin-like substances.

8. | Conclusion: Choose proven effectiveness with SuperLash

An eyelash serum containing prostaglandin is one of the most effective ways to achieve longer, fuller and stronger lashes, if carefully formulated and correctly applied.


SuperLash combines the power of prostaglandin analogues with a gentle, skin-friendly formula designed for daily use.
