SENSORYBarrier Strengthening
30,000 ppm Bifida Ferment Lysate fortifies the skin barrier, improves elasticity, and protects against environmental stressors.
Deep Hydration
Vitamin B5 (Panthenol) acts as a powerful humectant, drawing moisture into the skin and locking it in for long-lasting plumpness.
Soothing & Calming
Panthenol has proven anti-inflammatory properties that calm irritated, stressed, and reactive skin without irritation.

Niacinamide brightens skin tone and improves overall texture, while Bifida promotes healthy cell turnover for a luminous glow.
Safety & compatibility
SAFENo retinoids, salicylic acid, or hydroquinone present. However, contains added fragrance (parfum) which some practitioners advise avoiding during pregnancy. Consult your doctor.
Not safe. Contains Bifida Ferment Lysate (ferment), Cetearyl Olivate, Sorbitan Olivate (olive-derived fatty acid esters), and Polyglyceryl Laurates which can feed Malassezia yeast.
Rated 1/5 on the comedogenic scale. Lightweight watery formula with no heavy oils or pore-clogging waxes. Very unlikely to cause breakouts for most skin types.
Hypoallergenic tested. All ingredients are EWG Green Grade rated. Panthenol (irritancy score: 0) actively reduces irritation from other formula components.
Safe to layer with retinol, vitamin C, AHAs, and BHAs. No conflicting active ingredients. Pairs especially well with the Mary&May Vitamin C + Bifida Lotion.
Added fragrance (parfum) is listed near the end of the INCI list, suggesting a low concentration. Those with fragrance sensitivities should patch test first.
Ingredient breakdown
INGREDIENTSBifida Ferment Lysate 3% (30,000 ppm)Promising
A probiotic ingredient derived from fermented Bifidobacterium. Rich in amino acids, vitamins A, B, and C, it supports skin barrier repair, boosts elasticity, and helps protect against UV-induced damage. The same core ingredient used in premium serums like Estée Lauder Advanced Night Repair.
- Research: A study on 10% bacterial extract showed improved barrier function and decreased skin sensitivity in reactive skin types.
- Mechanism: Promotes DNA repair activity and provides protective benefits against UV-induced cellular damage.
- Concentration: At 3%, this is a meaningful dose for a toner, though lower than standalone bifida serums (typically 5-10%).
Panthenol (Vitamin B5) 0.1% (1,000 ppm)Proven
Pro-Vitamin B5 is a well-established humectant and skin soother. Originally discovered for its wound-healing properties in burn treatment, it draws moisture into the skin, reduces inflammation, and supports lipid production for a stronger barrier.
- Moisturizing: Attracts and retains water in the skin, providing long-lasting hydration without greasiness.
- Barrier repair: Stimulates lipid synthesis in the epidermis, strengthening the skin's natural protective layer.
- Anti-inflammatory: Clinically shown to reduce irritation caused by fragrance, preservatives, and chemical sunscreens in formulations.
Niacinamide (Vitamin B3) Undisclosed %Proven
A multi-functional skincare superstar with extensive clinical evidence. Works as a cell-communicating ingredient to brighten skin, minimize pores, control oil production, and improve uneven skin tone. Listed 5th in the INCI, suggesting a notable concentration.
- Brightening: Inhibits melanosome transfer to reduce hyperpigmentation and dark spots over time.
- Oil control: Regulates sebum production, making skin appear less oily without over-drying.
- Barrier support: Increases ceramide and fatty acid production in the stratum corneum.
Sodium Hyaluronate Undisclosed %Proven
A low-molecular-weight form of hyaluronic acid that penetrates deeper into the skin than regular HA. Can hold up to 1,000x its weight in water, providing intense hydration from within the skin layers.
- Hydration: Smaller molecular size allows deeper penetration and more effective moisture delivery than standard hyaluronic acid.
- Plumping: Reduces the appearance of fine lines by filling skin with moisture from the inside out.
Adenosine Undisclosed %Proven
A KFDA-approved anti-wrinkle ingredient commonly used in Korean skincare. Promotes collagen synthesis and has anti-inflammatory properties, supporting skin firmness and smoothness over time.
- Anti-aging: Stimulates collagen production and increases skin elasticity with consistent use.
- Soothing: Has anti-inflammatory benefits that complement the calming effects of panthenol.

How to use
HOW TO USECleanse Your Face
Start with clean skin. Use your preferred cleanser and gently pat your face dry, leaving it slightly damp for better absorption.
Dispense & Apply
Pump a moderate amount onto your palms or saturate a cotton pad. Gently pat or sweep across the face and neck, avoiding the eye area.
Pat Until Absorbed
Gently pat the toner into your skin until fully absorbed. The lightweight texture sinks in within seconds, leaving a dewy finish.
Optional: Toner Mask
For extra hydration, soak cotton pads with toner and place them on dehydrated areas for 5-10 minutes as a quick soothing mask.

- Your skin barrier feels compromised, tight, or reactive

Skin type compatibility
SKIN TYPESGlycerin, panthenol, hyaluronic acid, and bifida work together to deliver multi-layer hydration. Layer generously for maximum benefit.
Hypoallergenic tested with all EWG Green Grade ingredients. Panthenol soothes irritation. Slight caution due to added fragrance — patch test recommended.
Watery formula balances well across different face zones. Hydrates dry patches without making the T-zone oily or greasy.
Lightweight texture absorbs fast without greasiness. Niacinamide helps regulate sebum. Dewy finish may feel too moist for very oily types.
Low comedogenic rating (1/5) is favorable, but not fungal acne safe. Contains ferments and fatty acid esters. Good for non-fungal acne types.

Store in a cool, dry place away from direct sunlight. The brown glass bottle helps protect the bifida ferment lysate from light degradation.
Brown glass pump bottle — protects light-sensitive ingredients, hygienic dispensing, made with eco-conscious recycled paper and soybean oil ink.
Yes, under 100ml TSA limit at 120ml — just barely over. Glass bottle adds weight and fragility risk. Consider decanting into a travel container.
Frequently asked questions
FAQThis toner does not contain retinoids, salicylic acid, hydroquinone, or chemical sunscreens — the major ingredients to avoid during pregnancy. However, it does contain added fragrance (parfum), which some healthcare providers recommend avoiding during pregnancy and breastfeeding as a precaution. If you are pregnant or nursing, consult your OB-GYN or dermatologist before use.
No, this toner is not fungal acne safe. It contains several ingredients that can feed Malassezia yeast: Bifida Ferment Lysate (a fermented ingredient), Cetearyl Olivate and Sorbitan Olivate (olive-derived fatty acid esters), and Polyglyceryl-10/4 Laurate (lauric acid esters). If you struggle with fungal acne, consider the Anua Heartleaf 77% Soothing Toner or SKIN1004 Centella Toning Toner as alternatives.
Yes, this toner is compatible with retinol, vitamin C, AHAs, and BHAs. It contains no conflicting actives. In fact, the hydrating and soothing properties of panthenol and bifida make it an excellent prep step before applying stronger actives, helping to buffer potential irritation. Mary&May themselves recommend pairing it with their Vitamin C + Bifida Lotion for optimal synergy.
This toner is best suited for dry, dehydrated, sensitive, and combination skin types. It excels at providing hydration and barrier support. Oily skin types can also enjoy it thanks to its lightweight, non-greasy texture. However, those with active fungal acne should choose a different product due to the fermented ingredients.
Hydration is immediate from the first use — your skin will feel plumper and more comfortable. Barrier repair and soothing effects typically become noticeable within 2-3 weeks. Visible improvements in skin texture, brightness, and elasticity generally appear after 4-6 weeks of consistent morning and evening use.
Apply this toner as step 2 in your routine, immediately after cleansing and before essences, serums, and moisturizers. Use it both morning and evening. Apply to palms or a cotton pad and gently pat across the face and neck. You can also use it as a toner mask by soaking cotton pads for 5-10 minutes on dehydrated areas.
This toner has a low comedogenic rating of 1 out of 5. The watery, lightweight formula contains no heavy oils or pore-clogging waxes. The main ingredients — water, glycerin, bifida, panthenol, and niacinamide — are all non-comedogenic. It is very unlikely to cause breakouts for most skin types, though individual reactions can always vary.
The Period After Opening (PAO) is 12 months. Store it in a cool, dry place away from direct sunlight to maintain potency. The brown glass pump bottle helps protect the light-sensitive bifida ferment lysate from degradation. With twice-daily use, the 120ml bottle typically lasts 6-8 weeks.
Verdict: The Mary&May Vitamin B5 + Bifida Toner is a solid, budget-friendly K-beauty toner that delivers on its hydration and barrier-strengthening promises. The 3% Bifida Ferment Lysate and multi-layered hydrating ingredients (glycerin, panthenol, niacinamide, hyaluronic acid) create a genuinely effective formula at a competitive price. It is best suited for dry, sensitive, and combination skin types seeking a lightweight, fast-absorbing toner. The main drawbacks are the added fragrance (unexpected for a sensitive-skin product), the relatively low Vitamin B5 concentration at 0.1%, and the smaller 120ml bottle size compared to competitors. Not recommended for fungal acne-prone skin due to fermented ingredients.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.

Quick Product Notes
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.
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. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
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.
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.
