Look closely at the ingredient list on any ZÉORA bottle and you'll find Melissa Officinalis Flower/Leaf/Stem Extract. That's lemon balm, and it's one of only a handful of botanicals that appear in all three steps of the ZÉORA Ritual: Clarus, Oktélia and Hydronéa.
Here's what lemon balm is, what published research says about it (and what it doesn't), and why we put it in every step.
What lemon balm is
Lemon balm (Melissa officinalis) is a leafy herb from the mint family, Lamiaceae, the same plant family as sage and marjoram. Crush a leaf between your fingers and you'll notice the soft lemony scent that gives it its common name. Its botanical name has a story of its own: melissa is the Greek word for honeybee, a nod to how much bees are drawn to its flowers.
On ZÉORA labels, the extract is listed as Melissa Officinalis Flower/Leaf/Stem Extract, meaning it is drawn from the flowering parts, leaves and stems of the plant.
What research says about lemon balm
Lemon balm has been studied far more as a tea and supplement than as a skincare ingredient, so it's worth being precise about what the skin research covers.
- An antioxidant-rich herb. In a 2021 study published in Molecules, researchers tested a water-based lemon balm extract in the lab, where it showed antioxidant activity. When they applied it to the skin of hairless mice, they measured better skin hydration and less transepidermal water loss, the water that evaporates out through the skin (Molecules, 2021). This was an animal and laboratory study, not a study on people.
- Preparation matters. A 2026 review of lemon balm research in the journal Plants points out that its reported effects depend strongly on how it is prepared. Polyphenol-rich extracts behave differently from the plant's essential oil, and differences in plant parts and extraction methods make studies hard to compare (Plants, 2026).
None of these studies tested ZÉORA products. They help explain why lemon balm is valued as a botanical, not how it performs in a finished formula on your skin.
Why lemon balm is in ZÉORA
ZÉORA began with a notebook from 1850, kept by a woman named Zéora on the Greek island of Samos. She had reactive, sensitive skin and studied the plants growing around her, keeping only what her skin accepted. Lemon balm is a familiar Mediterranean garden herb, and it sits naturally beside the other plants in her story.
It's one of the seven botanicals of our Samos Garden, alongside Greek-sourced yarrow, sage, damask rose, chamomile, green tea and marjoram. The same seven plants appear in every step, so lemon balm travels with you through the whole routine. We chose it to help skin look fresh and feel comfortable, and to support skin as it faces everyday environmental stress.
Where you'll find it
- Clarus, our gentle gel cleanser (100 ml).
- Oktélia, our lightweight serum (30 ml).
- Hydronéa, our replenishing cream (50 ml).
All three come together in The ZÉORA Ritual.
How to use the Ritual
- Clarus · Cleanse. Massage 1–2 pumps of Clarus onto damp skin for a few seconds, rinse lightly and pat dry.
- Oktélia · Calm. Apply 3 drops of Oktélia, one on the forehead and one on each cheek, and spread until absorbed.
- Hydronéa · Restore. Smooth Hydronéa evenly over clean skin to seal in hydration.
Use the routine morning and evening. Hydronéa does not contain SPF, so in the morning finish with a broad-spectrum sunscreen you already tolerate.
A note for sensitive skin
Hydronéa is our fragrance-free step. Clarus and Oktélia do contain fragrance, and every full ingredient list is on its product page, so you can check each one before you buy.
If your skin is sensitive, introduce one new product at a time and patch-test first. The American Academy of Dermatology explains how to test a skincare product before using it on your face.
