Is it allergies?
Or is it dry eyes?

It can be difficult to differentiate between the two conditions. The good news is that there can be one all-round solution for both dry eye and allergy symptoms.

The symptoms can be similar

Both dry eyes and allergies can present similar symptoms, which are those of irritation (e.g.: burning, itching, tearing, foreign body sensation, etc.).

Nature's ingenuity to the rescue

Leveraging the intuition of nature, you can protect your eyes against allergens, reduce dehydration and irritation, and keep your tears from evaporating excessively. 

Ectoine and Sodium Hyaluronate are both natural substances that can help you find relief from both allergies and dry eyes

The all round drop for both dry eyes and allergy relief

HYLO-DUAL® combines the power of Sodium Hyaluronate and Ectoine to provide long-lasting relief of both dry eye and allergy symptoms.

This all-round drop relieves itching and burning, protects your eyes from allergens, and helps reduce the excessive evaporation of tears.

Ectoine: nature's answer to extreme environments

There are places on Planet Earth that are so extreme, that life should not be able to exist. But some microorganisms, called extremophiles, found a way to shield their bodies and thrive. 

Extremophiles "shield" themselves by forming extremolytes like Ectoine

The "shield"

Ectoine has a strong water-binding capacity. The water surrounding Ectoine is bound very compact, and forms a physiologic barrier.


This “shield” of Ectoine and water protects cell membranes from contact with allergenic substances and against inflammatory responses to environmental stress (such as dehydration, e.g. by hyperosmolar tears, UV radiation or airborne allergens).

When you thought there couldn't be more benefits

Additionally, Ectoine helps protect against the excessive evaporation of tears. Ectoine has a stabilizing effect on the lipid phase (oily layer) of the tear film.


The lipid layer is the outermost layer of our tears. Its function is to reduce the tears from evaporating. Ectoine helps increase its elasticity, causing it to spread evenly over the eye surface and protects against the excessive evaporation of tears.


A powerful combination

HYLO-DUAL® eye drops also contain Sodium Hyaluronate, the sodium salt of Hyaluronic Acid, which forms a regular, stable, and long-lasting lubricating film on the eye surface.


Together, Sodium Hyaluronate and Ectoine provide intensive, long-lasting lubrication of the ocular surface and protect against the evaporation of tears to relieve itching and burning caused by inflammation and allergies.
