Key actives
Rosmarinus Officinalis (Rosemary) Leaf Extractplant extract
Rosemary Leaf Extract carries rosmarinic and carnosic acids, both effective antioxidants. It is often there to keep the oils in a formula from going rancid. It is the entry this serum is named after, and the list carries it.
Succinic Acidactive
Succinic Acid is a small organic acid used for the look of blemish-prone skin and as a pH adjuster. It is far milder than an AHA at the levels used here. It is named eleventh on this serum's list, alongside Rosmarinus Officinalis (Rosemary) Leaf Extract.
Allantoinactive
Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. The panel names it twentieth on this serum's list, beside Rosmarinus Officinalis (Rosemary) Leaf Extract.
Lactic Acidexfoliant
Lactic Acid is a larger AHA than glycolic, so it works nearer the surface and is easier on skin, and it is a humectant as well as an exfoliant. It is the AHA of choice for dry skin. It is named second on this serum's list, alongside Rosmarinus Officinalis (Rosemary) Leaf Extract.
Melia Azadirachta Leaf Extractplant extract
Melia Azadirachta is neem. Its leaf and flower extracts are long-standing Ayurvedic ingredients, and Korean formulas use them in products aimed at the look of congested, blemish-prone skin. It is named fourteenth on this serum's list, alongside Rosmarinus Officinalis (Rosemary) Leaf Extract.
How to use
- Apply a small amount to cleansed, toned skin, pat in gently, then follow with a moisturizer.
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Rosmarinus Officinalis (Rosemary) Leaf Extract and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Rosmarinus Officinalis (Rosemary) Leaf Extract and all. We match this serum to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Rosmarinus Officinalis (Rosemary) Leaf Extract?
Succinic Acid, Allantoin and Lactic Acid. The order they are printed in on this serum's panel is the order on the box, so you can see where Rosmarinus Officinalis (Rosemary) Leaf Extract sits relative to them. Further down the same panel: Melia Azadirachta Leaf Extract, Hydrolyzed Gardenia Florida Extract and Hydrolyzed Malt Extract.

How it works
The Rosemary AHA Night Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The plant extract it is built around is Rosmarinus Officinalis (Rosemary) Leaf Extract, named ninth on its own ingredient list. The same list carries Succinic Acid, Allantoin and Lactic Acid, so the plant extract is not the only thing on it worth naming. How much of the Rosmarinus Officinalis (Rosemary) Leaf Extract stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum KAINE sells in Korea, Rosmarinus Officinalis (Rosemary) Leaf Extract and all.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Rosmarinus Officinalis (Rosemary) Leaf Extract on the list.
- Lactic Acid on this list makes this serum an exfoliating step, so do not stack it with another one on the same night.
