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 usually ends up running two products: something for the oil and something for the marks left behind. Mary&May combines both on a 93% Chaenomeles Sinensis base, the Korean Quince used in traditional medicine for its astringent and antimicrobial properties, with 2% Niacinamide alongside it. The Seoul brand builds on high concentrations and publishes its full ingredient breakdown.
Key Benefits
- Korean Quince at 93% regulates oil and bacteria together. Its polyphenols, organic acids, and saponins tighten and moderate sebum through astringent activity, while working against the bacteria involved in congestion. At 93% it is the base of the serum, not a note in it.
- Niacinamide at 2% fades marks without the flush. It blocks pigment transfer to the surface to work on post-breakout marks, supports ceramide production, and adds its own sebum regulation. At 2% it avoids the flushing that higher concentrations cause in some people.
- The quince polyphenols calm active redness. Their anti-inflammatory activity works on the redness around a breakout and the sensitivity that lingers afterwards, so the serum is useful at both stages.
Texture & Finish
Water-light and immediately absorbed, leaving no residue, film, or shine. It is light enough to use morning and evening on oily skin without adding to congestion.
Ideal For
- Skin types: Oily, combination, and breakout-prone skin.
- Skin concerns: Excess oil, congestion and breakouts, post-breakout marks, uneven tone, and redness.
- Best used by: Skin that is dealing with active breakouts and the marks from the last round at the same time.
FAQ
Q: How is this different from a Niacinamide-only brightening serum?
A: Niacinamide is doing the same work here that it does anywhere: pigment transfer and sebum. What changes is the base. Instead of water and humectants, it sits on 93% Korean Quince, which adds astringent oil control and antimicrobial activity that a Niacinamide serum has no way to provide. If your marks come from breakouts rather than sun, that combination is the relevant one.
Q: Is 2% Niacinamide too low to work?
A: No. Most published research on Niacinamide's effects on pigmentation and barrier function used 2% to 5%, and higher concentrations mainly increase the flushing and irritation rather than the benefit. 2% is a working dose, chosen for tolerability.
Q: Can I use it with acids or a retinoid?
A: Yes. Niacinamide sits comfortably with both, and the calming quince base can take some edge off a routine running acids or retinoids. Stack them thoughtfully rather than all in one evening.
Treating the breakout and the mark it leaves as one problem saves a step, and usually a fair amount of irritation.
