Quick answer
How do I shop by ingredient?
Pick the page that matches your problem. For a dry, gritty surface, start with hyaluronic acid drops. For crusty, red, or irritated lids, start with hypochlorous acid for the eyelids. For longer-term support from the inside, read the omega-3s guide. Each guide explains the ingredient and shows the products that use it.

The active ingredient is what does the job
Two products can look similar on the shelf and work very differently, because the active ingredient is what does the job. Knowing whether a drop is built on hyaluronic acid, a lipid, or something else helps you match it to your type of dryness, and it explains why a lid rinse and an eye drop are not interchangeable.

Dry Eye Rescue Tip
Dry eyes and crusty lids usually need both
If your eyes are dry and your lids are also crusty or red, you likely need both: a hyaluronic acid drop for the surface and a hypochlorous acid rinse for the lids. They work on different problems, so using one does not replace the other.

What does shopping by ingredient mean?
It means choosing a product by its key active ingredient and what that ingredient does, rather than by brand. Each ingredient page explains the science and shows the products that use it.
Which ingredient is right for me?
It depends on your dryness. Hyaluronic acid holds moisture on the eye for daily dryness, while hypochlorous acid cleans the lids when blepharitis or lid issues are part of the picture.
Can I use more than one?
Yes. Many people use a hyaluronic acid drop for the eye surface and a hypochlorous acid rinse for the lids, since they do different jobs.
Are these ingredients safe?
Both have a strong safety record when used as directed. Follow the product label, and ask your eye doctor if you have an eye condition or wear contacts.
Do you have more ingredients coming?
Yes. This is a growing area, and more ingredient guides will be added over time, starting with lipids. Omega-3s now have their own guide.
Is shopping by ingredient a replacement for a diagnosis?
No. It helps you understand your options, but persistent symptoms should be evaluated by an eye care professional who can identify the cause.
Where do I start if I am not sure?
If your eyes feel dry and gritty, start with hyaluronic acid drops. If your lids are crusty, red, or irritated, start with hypochlorous acid for the lids.
