How it works
Succinic Acid is named on the ingredient panel on this serum. 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. On this panel it sits alongside Niacinamide, Salicylic Acid and Melia Azadirachta Leaf Extract. Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.

Key actives
Succinic Acid
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.
Niacinamide
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
Salicylic Acid
Salicylic Acid is a BHA, and the only common exfoliant that is oil soluble, so it can work inside a pore rather than only on the surface. It loosens the dead cells that block pores and is used for the look of congested, oily skin.
Melia Azadirachta Leaf 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.

What does the Red Succinic Acid Trace Serum actually contain?
Its ingredient list is led by Niacinamide, with the rest of the formula built to support that active rather than compete with it. We list the ingredients in the order the manufacturer prints them, so the ones near the top of the panel are doing the most work in the formula.
How do I use the Red Succinic Acid Trace Serum?
Use this serum as the treatment step right after toner. To apply, smooth or press onto cleansed, toned skin and follow with moisturizer. Keep it to AM/PM unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step. Give it a full bottle or box before judging the result, since most Korean routines are built for steady use rather than a single application.
Is the Red Succinic Acid Trace Serum the same formula sold in Korea, or a US version?
This Red Succinic Acid Trace Serum is the Korean-market formula, not a version reformulated for US shelves. It arrives with its original Korean-market barcode and batch code intact so the formula can be checked against the box on arrival.
Can I use the Red Succinic Acid Trace Serum with other actives in my routine?
Yes, as long as it is used in its own step, the treatment step right after toner, and not layered on top of a product doing the same job. Introduce any new step gradually over the first week or two and keep an eye on how the skin responds before adding a second new active alongside it.
Who is the Red Succinic Acid Trace Serum suited for?
It suits most skin types looking for treatment step right after toner rather than a single acute problem. It comes in a 30ml format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

How to use
- Use the Red Succinic Acid Trace Serum after toner and before moisturizer, in the evening.
- Three or four drops covers the whole face. Press it in with flat palms instead of rubbing it around.
- Toner first so the surface is damp, then this, then about a minute before your moisturizer goes over the top. Salicylic acid is the entry that puts this step in the evening rather than the morning.
- Start at two or three evenings a week and build up from there, because salicylic acid is on this list. Do not use it in the same routine as another resurfacing acid or a retinoid.
Worth knowing
- Introduce it two to three nights a week at first and watch how the skin responds before moving to nightly use.
- Pair it with a daily sunscreen step, since brightening and exfoliating actives can make skin more reactive to sun exposure.

BHAs like salicylic acid get really deep into the pores, whereas the water-soluble ones don't go as deep.
