Ingredient breakdown

INGREDIENTS

Chaenomeles Sinensis Fruit Extract 93%Promising

Also known as Chinese Quince. The hero base ingredient, replacing standard water in this formula. Naturally rich in Vitamin C, flavonoids, polyphenols and tannins.

  • Function: Antioxidant, brightening, smoothing.
  • Vitamin C content: Provides gentle, plant-derived ascorbic acid for added radiance.
  • Tannins: Contribute to a slightly astringent, pore-tightening feel.

Niacinamide (Vitamin B3) 2%Proven

The star active ingredient. One of the most well-researched skincare ingredients with multiple proven benefits.

  • Pigmentation: Blocks melanosome transfer from melanocytes to keratinocytes, reducing dark spots.
  • Sebum control: Studies show reduced sebum excretion at concentrations of 2% and above.
  • Barrier function: Stimulates ceramide synthesis, strengthening the skin barrier.
  • Tolerance: 2% is gentle enough for sensitive skin and niacinamide newbies.
The 2% concentration is intentionally lower than common 5–10% serums — gentler, less risk of irritation, ideal for daily layering.

Glycereth-26 HumectantProven

A glycerin-based humectant and emollient that draws moisture into the skin and gives the formula its smooth, slightly cushioned feel.

  • Comedogenicity: 0 — non-pore-clogging.
  • Irritancy: 0 — extremely gentle.

Arginine Amino AcidProven

A semi-essential amino acid that's a building block of collagen and a natural moisturizing factor (NMF) in skin.

  • Hydration: Acts as a humectant, attracting water to the upper skin layers.
  • Wound healing: May help support skin repair.
  • pH adjuster: Helps stabilize formula pH for skin compatibility.

1,2-Hexanediol + Caprylyl Glycol + Ethylhexylglycerin PreservationProven

A modern, alcohol-free preservation system that keeps the formula stable without harsh parabens.

  • 1,2-Hexanediol: Multifunctional — humectant, solvent and antimicrobial booster.
  • Caprylyl Glycol: Provides slip and skin conditioning while supporting preservation.
  • Ethylhexylglycerin: Boosts efficacy of other preservatives.

Carbomer TexturizerProven

A common gelling agent that gives the serum its light, slightly thickened gel consistency without adding any greasiness.

  • Inert: No biological activity, purely textural.
  • Non-irritating: Considered safe at the levels used in cosmetics.

8 ingredients

Chaenomeles Sinensis Fruit Extract (93%), Glycereth-26, Niacinamide (2%), 1,2-Hexanediol, Arginine, Carbomer, Ethylhexylglycerin, Caprylyl Glycol

Apply after toner/essence and before heavier creams. As a water-based gel serum, it should go on relatively bare, freshly cleansed skin so the actives can penetrate.

How to use

HOW TO USE
1

Cleanse & Tone

Start with a clean face. Apply your toner or hydrating essence first if you use one.

2

Dispense 3–4 Drops

Squeeze the dropper to release a pea-sized gel "blob" into your palm. The texture is gel-like rather than runny.

3

Press Into Skin

Pat gently across face and neck. Avoid rubbing — let the serum sink in for 30 seconds.

4

Lock With Moisturizer

Follow with your moisturizer. In the morning, always finish with broad-spectrum SPF 30+.

5

Use AM & PM

Suitable for daily twice-daily use. Consistent use over 4–8 weeks delivers the most visible brightening results.

06

Who is it for?

WHO

  • You have oily or combination skin and want sebum balance
  • You prefer minimalist, fragrance-free formulas

  • You expect dramatic results in under 2 weeks

  • You dislike gel-textured products or droppers
  • You have a known allergy to rose-family fruits (quince family)

Skin type compatibility

SKIN TYPES
Oily Skin
Excellent

Lightweight gel absorbs fast without adding shine. Niacinamide directly helps regulate sebum.

Dry Skin
Good

Provides light hydration via glycereth-26 and arginine, but you'll want a richer cream layered on top.

Combination
Excellent

Balances oily T-zone while still feeling comfortable on drier cheeks. Layers seamlessly.

Sensitive
Excellent

Only 8 ingredients, fragrance-free, alcohol-free. Low 2% niacinamide minimizes flushing risk.

Acne-Prone
Excellent

Non-comedogenic and fungal-acne safe. Niacinamide helps fade post-acne marks (PIE/PIH).

Mature Skin
Good

Solid maintenance brightener but pair with retinol or peptides for stronger anti-aging effects.

Frequently asked questions

FAQ

Yes. The serum contains no retinoids, salicylic acid, hydroquinone or chemical sunscreen filters — the actives most often flagged in pregnancy. Niacinamide is widely considered safe during pregnancy and breastfeeding by dermatologists, and Chinese Quince extract is a gentle plant ingredient. As always, run any new product past your OB-GYN if you're unsure.

Yes. The 8-ingredient formula contains no fatty acids, fatty alcohols, esters, polysorbates, oils or fermented ingredients that could feed malassezia yeast. It's a safe choice for those managing fungal acne / pityrosporum folliculitis.

Yes — niacinamide is one of the most cooperative actives in skincare. It pairs well with retinol (and may reduce its irritation), with most vitamin C forms, and with AHAs/BHAs. The classic concern about niacinamide + L-ascorbic acid forming "niacin" has been largely debunked by modern research. To minimize any chance of irritation, you can apply them at different times (e.g., vitamin C in the AM, niacinamide in the PM).

It's most ideal for oily, combination, sensitive and acne-prone skin thanks to its lightweight gel texture and sebum-balancing effects. Dry skin types can absolutely use it as a brightening layer, but should follow with a richer moisturizer for adequate hydration. Mature skin can benefit from the antioxidant quince extract but may want a stronger anti-aging companion product.

Hydration and a softer, smoother feel are noticeable almost immediately. Sebum balancing and refined-pore effects typically appear within 2–4 weeks. Visible brightening of dark spots and post-acne marks usually requires 6–8 weeks of consistent twice-daily use, since pigment turnover happens slowly. Niacinamide is a "slow and steady" ingredient — patience pays off.

After cleansing, toner and any watery essence, but before heavier serums, ampoules and moisturizer. As a gel-textured serum, it works best when applied to relatively bare skin so it can absorb properly. In the morning, always finish your routine with a broad-spectrum SPF 30 or higher — niacinamide helps fade pigmentation, but UV exposure is what causes it in the first place.

No — it has a 0/5 comedogenic rating. The formula is water-based with no oils, butters, waxes or other pore-clogging ingredients. In fact, niacinamide actively helps regulate sebum and may reduce the appearance of clogged pores over time.

The Period After Opening (PAO) is 12 months. Once opened, use within one year for maximum effectiveness of the niacinamide and quince extract. Store away from direct sunlight and excessive heat. If the color or smell changes noticeably, discontinue use.

— Skincarisma verdict
4.6 / 5 ★★★★★

Verdict: Mary & May's Niacinamide + Chaenomeles Sinensis Serum is one of the cleanest, most beginner-friendly niacinamide serums on the K-beauty market. The minimalist 8-ingredient formula, with 93% Chinese Quince extract replacing water, makes this a standout choice for sensitive, acne-prone, pregnant or fungal-acne-affected users who can't tolerate harsher actives. The 2% niacinamide is lower than competitors like The Ordinary or COSRX — that's a deliberate, gentle choice rather than a flaw. If you want fast, dramatic brightening, look elsewhere. If you want a safe, well-tolerated, long-haul brightener that plays nicely with everything in your routine, this is excellent value.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either.

lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
