How it works
Medicube Red Acne Succinic Acid Peeling Serum is a serum built for the treatment step right after toner. Its ingredient list leads with Succinic Acid, Salicylic Acid, and Panthenol, so the formula's stated purpose lines up with what actually sits near the top of that list rather than with a single marketing ingredient buried further down. Succinic Acid does the most work here as a clarity, and the remaining actives round out the texture and finish rather than compete for attention. Placed as the treatment step right after toner, it is meant to be used AM/PM rather than swapped freely between steps. Because this is the Korean-market version of the Red Acne Succinic Acid Peeling Serum line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.

- The Korean-market Medicube formula for Red Acne Succinic Acid Peeling Serum, matching what Medicube sells in Korea rather than a US-reformulated line.
Key actives
Succinic AcidClarity
Succinic Acid sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for clarity: a mild acid chosen for blemish-prone skin, included to support a clearer-looking surface without the sharper sting of stronger exfoliating acids.
Salicylic AcidPore care
Salicylic Acid sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for pore care: a BHA that works inside the pore lining, included at a level meant for regular use on textured, congestion-prone skin.
PanthenolComfort
Panthenol sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for comfort: provitamin B5, a humectant and comfort ingredient that softens the finish and helps a formula feel less drying over repeated use.
AllantoinComfort
Allantoin sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for comfort: a comfort ingredient with a long safety record, added to keep the finish gentle on skin that is dealing with dryness or mild sensitivity.
Medicube Red Acne Succinic Acid Peeling Serum
What does the Red Acne Succinic Acid Peeling Serum actually contain?
Its ingredient list is led by Succinic Acid, 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 Acne Succinic Acid Peeling 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 Acne Succinic Acid Peeling Serum the same formula sold in Korea, or a US version?
This Red Acne Succinic Acid Peeling 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 Acne Succinic Acid Peeling 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 Acne Succinic Acid Peeling 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 40g 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 Acne Succinic Acid Peeling 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. Glycolic 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 glycolic 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.

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
BHAs like salicylic acid get really deep into the pores, whereas the water-soluble ones don't go as deep.
Samantha Stein, PA-CDermatology physician assistant, Cleveland Clinic Pantothenol is a common ingredient in skin care and hair products I recommend, particularly for people who are prone to dryness.

Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.
