Mary&May Niacinamide + Chaenomeles Sinensis Serum
Skin-Nomad's Take — At a Glance
- 93% Korean Quince with 2% Niacinamide
- Manages oil, brightens marks, and calms in one step
- Water-light, so it works twice a day on oily skin
Oily, breakout-prone skin normally ends up running two products at once, one for the shine and one for the marks the last breakout left behind. The Mary&May Niacinamide + Chaenomeles Sinensis Serum puts both jobs on a single base of 93% Korean Quince, the astringent fruit extract long used in Korean herbal medicine, with 2% Niacinamide working alongside it. The Seoul brand formulates at concentrations high enough that publishing the full breakdown works in its favour.
Key Benefits
- Korean Quince at 93% takes on oil and bacteria together: Its polyphenols, organic acids and saponins tighten the surface and moderate sebum through astringent activity, while working against the bacteria involved in congestion. At 93% the quince is the base of the serum, not a botanical note in it.
- At 2%, Niacinamide is doing three jobs at once: Niacinamide blocks the transfer of pigment up to the skin's surface, which is the mechanism that shifts post-breakout marks, and it raises ceramide production and moderates sebum alongside that. At 2% it manages all three without the flushing that higher doses set off in some people.
- Calming is built into the base rather than added on top: The quince polyphenols carry anti-inflammatory activity that reaches both the redness around a fresh breakout and the sensitivity left behind once it settles. That is why the serum stays useful at both ends of a breakout rather than only the loud end.
Texture & Finish
Water-light and absorbed almost on contact, with no residue, film or shine left behind. It is light enough for morning and evening use on oily skin without adding to congestion, and it disappears under everything layered over it.
Ideal For
- Skin types: Oily, combination, and breakout-prone skin, teenage skin included.
- Skin concerns: Excess oil, congestion and breakouts, post-breakout marks, uneven tone, and redness.
- Best used by: Skin that is handling a fresh breakout and the marks from the last round at the same time gets the most out of this serum.
FAQ
Q: How is this different from a Niacinamide-only brightening serum?
A: The Niacinamide is doing the same work here that it does anywhere, on pigment transfer and sebum. What changes is what it is sitting in. The Mary&May Niacinamide + Chaenomeles Sinensis Serum builds on 93% Korean Quince instead of water and hydrating agents, which adds astringent oil control and antimicrobial activity that a Niacinamide serum has no way to provide on its own.
Q: Is 2% Niacinamide too low to do anything?
A: No. Most of the published research on Niacinamide's effects on pigmentation and barrier function used concentrations between 2% and 5%, so this sits at the lower end of the evidenced range rather than below it. The number to watch on a Niacinamide serum is tolerability, not maximum strength.
Q: Can I use it alongside acids or a retinoid?
A: Yes. Niacinamide sits comfortably with both, and the calming quince base takes some of the edge off a routine that already runs acids or retinoids. Spread the stronger actives across different evenings rather than stacking them all into one.
Skin in the middle of a breakout is already irritated, which is the argument for a serum that calms while it works rather than one that trades comfort for speed.
