Pore_Laserβ„’ Complex

A patented blend of jasmine, willow bark and eggplant extracts that targets excess sebum and visibly minimizes the look of enlarged pores.

πŸ§ͺ

Triple-Acid Exfoliation

AHA (citric acid), BHA (betaine salicylate) and PHA (gluconolactone) gently dissolve dead skin and unclog pores without harsh scrubbing.

πŸ’§

Glass-Skin Hydration

Low-molecular hyaluronic acid, panthenol and allantoin deliver deep moisture, so skin stays plump and comfortable rather than stripped.

❄️

Cooling Sebum Control

Menthyl lactate and niacinamide leave a refreshing, cooling finish while helping to balance oil across the T-zone.

πŸ›‘οΈ Safety & Compatibility

⚠️
Pregnancy & Breastfeeding

Contains betaine salicylate, a BHA. Low-dose topical salicylates are generally considered low risk, but salicylic-acid derivatives are commonly flagged during pregnancy β€” check with your doctor first.

βœ…
Fungal-Acne (Malassezia) Safe

Independently verified as free from the fatty acids, esters, polysorbates and ferments that typically feed malassezia yeast.

⚠️
Layering With Other Actives

Plays well with hydrating serums and niacinamide. Avoid stacking with strong AHAs, retinol or vitamin C in the same routine to limit irritation.

β˜€οΈ
Sun Sensitivity

Exfoliating acids can increase sun sensitivity. Always follow with a broad-spectrum SPF in the morning.

πŸ”¬ Ingredient Breakdown

🌟 Niacinamide ~2% Proven

A multitasking form of vitamin B3 and one of the headline actives, sitting third on the ingredient list. It brightens dullness, supports the skin barrier and helps regulate oil, making it a natural fit for pore-prone skin.

  • Source: Dermatology research widely shows that 2–5% niacinamide can strengthen the barrier and reduce the appearance of sebum and pores.
  • Bonus: Pairs safely with the acids in this formula and rarely causes irritation.

🧴 Betaine Salicylate BHA Proven

A gentle, plant-derived salicylic-acid alternative. Being oil-soluble, it penetrates inside pores to dissolve sebum and loosen blackheads and whiteheads β€” the key to the toner's pore-clearing action.

  • Source: Salicylic-acid derivatives are well established for keratolytic (dead-skin-dissolving) and pore-decongesting benefits.
⚠️
As a BHA, it can be drying if over-used and is the reason this toner is flagged "caution" for pregnancy.

🫧 Gluconolactone PHA Proven

A polyhydroxy acid that exfoliates the very surface of the skin while also acting as a humectant. Its larger molecule makes it gentler and more hydrating than traditional AHAs β€” ideal for daily use and sensitive skin.

  • Source: PHAs are documented to exfoliate with less stinging and irritation than glycolic or lactic acid.

πŸ‹ Citric Acid AHA Promising

An alpha-hydroxy acid that provides light surface exfoliation and helps keep the formula at a skin-friendly pH so the other acids work effectively.

  • Source: AHAs help loosen dead surface cells, supporting smoother texture and a brighter look over time.

πŸ’§ Hydrolyzed Hyaluronic Acid <1% Proven

A low-molecular-weight form of hyaluronic acid able to settle into the upper layers of skin, where it binds water to counterbalance the exfoliating acids and keep skin plump.

  • Source: Smaller HA fragments are shown to hydrate beyond the very surface for a longer-lasting moisture cushion.

🌿 Panthenol ~1% Proven

Pro-vitamin B5, a soothing humectant that helps reduce water loss and calm any tightness that exfoliation might cause.

  • Source: Panthenol is well documented to support barrier repair and reduce trans-epidermal water loss.

🌼 Allantoin ~0.3% Proven

A classic calming and skin-conditioning agent that softens and soothes β€” a helpful buffer alongside the acid trio.

  • Source: Allantoin is recognized for its soothing, keratolytic and skin-protective properties.

🌱 Salix Alba (Willow) Bark Extract Plant Promising

A natural source of salicin that complements the BHA, reinforcing the formula's gentle pore-clearing and soothing profile. It is also part of the brand's Pore_Laserβ„’ complex.

  • Source: Willow bark has a long traditional and cosmetic history for blemish-prone and congested skin.

πŸ‘€ Who Is It For?

βœ… Perfect for you if:

  • Exfoliating acids require diligent daily SPF

❓ Frequently Asked Questions

Use with caution. The toner contains betaine salicylate, a BHA (salicylic-acid derivative). Low-concentration topical salicylates in leave-on products are generally considered low risk, but BHAs are commonly flagged during pregnancy, so we recommend checking with your OB/GYN or doctor before adding it to your routine.

Yes. It has been independently verified as fungal-acne (malassezia) safe, meaning it doesn't contain the fatty acids, problematic esters, polysorbates or fermented ingredients that typically feed malassezia yeast. As always, individual reactions vary, so patch testing is wise if you're prone to flare-ups.

This toner already contains mild AHA, BHA and PHA. You can comfortably pair it with hydrating serums, niacinamide and moisturizers. To avoid over-exfoliation and irritation, don't layer it with strong retinol, vitamin C or extra acid treatments in the same routine β€” alternate them across AM/PM or different days instead.

It shines on oily, combination and pore-conscious skin, and normal skin benefits too. Dry and sensitive skin can still use it, but should patch test, start a few times a week, and always follow with a richer moisturizer.

Skin typically feels smoother and refreshed after the first use. Oil control tends to improve within a week, and the brand's clinical testing reported visible pore and blackhead improvement at around the 2-week mark, with the glass-skin glow building over 4+ weeks of consistent use.

It's a first treatment step. Apply it straight after cleansing and before essences, serums and moisturizer. In the morning, always finish with sunscreen since the acids can increase sun sensitivity.

No. It's a lightweight, water-based, non-comedogenic formula (rating about 1/5) designed to clear and refine pores rather than clog them. The tiny amounts of plant oils sit very low on the ingredient list.

It has a 12-month PAO (Period After Opening). For best results and freshness, use it up within 12 months of opening and store it away from heat and direct sunlight.

4.5 out of 5

Verdict: The MediCube Zero Pore Toner is a standout daily exfoliating toner that delivers on its core promise β€” smoother texture, less visible oil and refined pores β€” backed by solid clinical data and a generous 250ml size at an accessible price. The triple AHAΒ·BHAΒ·PHA blend is gentle enough for frequent use yet effective, and the hyaluronic acid, panthenol and niacinamide keep skin hydrated rather than stripped. The cooling menthol finish and subtle plant-oil scent won't suit everyone, and very dry or highly sensitive skin should ease in slowly with diligent SPF. For oily, combination and pore-conscious skin, it's an easy, high-value addition to a K-beauty routine.

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 Β«promisesΒ» 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.

question
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.
