Pregnancy / Breastfeeding

No retinoids, BHA or hydroquinone, but tea tree is debated during pregnancy. Confirm with your OB/GYN first.

βœ…

πŸ”¬ Ingredient Breakdown

🌿 Houttuynia Cordata Extract 85% Promising

The star of the formula and the brand's signature ingredient. Houttuynia cordata (fish mint / heartleaf) is an East Asian plant traditionally used to detoxify and soothe, and replaces water as the base of this serum at 85%.

  • Actives: Rich in polyphenolic flavonoids such as quercetin, quercitrin, hyperoside and rutin.
  • Soothing: An in-vitro study found strong anti-allergic effects with potential to help calm conditions like eczema.
  • Use case: Antioxidant support that helps soothe redness and visibly refine the appearance of pores.
βœ…
Used at base concentration instead of water β€” far higher than typical "centella-style" soothing serums.

🦠 Melaleuca Alternifolia (Tea Tree) Extract 9.7% Proven

Sourced from Australian tea tree, this extract carries the plant's well-known antimicrobial reputation in a gentler, water-soluble form than tea tree essential oil.

  • Antibacterial: Tea tree is documented for antimicrobial and anti-acne activity against blemish-causing bacteria.
  • Purifying: Manufacturers cite soothing, antiseptic and pore-purifying benefits for the extract form.
  • Gentler form: Extract delivers active components at lower, less irritating levels than neat essential oil.
⚠️
Tea tree can sensitize very reactive skin β€” patch test first and discuss with a doctor if pregnant.

πŸ’§ Glycereth-26 & 1,2-Hexanediol Support Proven

The hydration and texture backbone of the formula. Glycereth-26 is a humectant/emollient that draws in moisture, while 1,2-Hexanediol hydrates and doubles as a gentle, low-irritation preservative booster.

  • Glycereth-26: Comedogenicity 0, irritancy 0 β€” lightweight moisture without grease.
  • 1,2-Hexanediol: Helps preserve the formula and improves skin feel.
  • Result: Keeps a botanical-heavy serum stable, watery and fast to absorb.

πŸ§ͺ Arginine, Carbomer, Ethylhexylglycerin & Caprylyl Glycol Base Proven

The functional supporting cast. Arginine is an amino acid that balances pH, Carbomer thickens the watery base into a light gel, and Ethylhexylglycerin + Caprylyl Glycol act as a mild, paraben-free preservative system that also conditions skin.

  • Arginine: Amino acid that helps neutralize the formula to a skin-friendly pH.
  • Carbomer: Gives the watery extract a smooth, spreadable gel texture.
  • Caprylyl Glycol: Humectant + preservative-booster, well tolerated by sensitive skin.

8 ingredients

Houttuynia Cordata Extract (85%), Melaleuca Alternifolia (Tea Tree) Extract (9.7%), Glycereth-26, 1,2-Hexanediol, Arginine, Carbomer, Ethylhexylglycerin, Caprylyl Glycol.

Apply after toner, at the essence/serum step, before heavier creams. Suitable for both AM and PM use; always finish with SPF in the morning.

πŸ“ How to Use

1

Cleanse & tone

Start with clean skin and your usual toner so the serum absorbs into a balanced surface.

2

Dispense a moderate amount

Use a few drops β€” enough to cover the face and neck without over-saturating.

3

Pat to absorb

Gently smooth and pat across the face and neck for even, fast absorption.

4

Seal & protect

Follow with moisturizer to lock in hydration. In the morning, finish with sunscreen.

πŸ‘€ Who Is It For?

βœ… Perfect for you if:

  • You have oily, combination or acne-prone skin
  • You deal with congested pores and frequent breakouts
  • You have sensitive, easily irritated or redness-prone skin
  • You prefer short, fragrance-free ingredient lists
  • You want a lightweight layer that won't feel heavy

❌ Consider alternatives if:

  • Your skin is very dry and needs rich, occlusive hydration
  • You're specifically chasing anti-aging or brightening actives
  • You have a known sensitivity to tea tree
  • You're pregnant and want to avoid tea tree entirely
  • You want a serum that doubles as your only moisturizer

βš–οΈ Pros & Cons

βœ… Praised

  • Calms irritation, redness and small painful bumps fast
  • Very high active concentration for the price
  • Lightweight, non-sticky and absorbs quickly
  • Short, fragrance-free, fungal-acne safe ingredient list
  • Great everyday value and gentle on sensitive skin

❌ Criticized

  • Small 30ml bottle runs out quickly
  • Natural tea tree note isn't truly "scent-free" for everyone
  • Greenish-yellow tint can look off-putting at first
  • Too light to be a standalone moisturizer for dry skin
  • Tea tree may not suit pregnancy or very reactive skin

~$12 Budget Pick

A near-single-ingredient houttuynia extract at a lower price and bigger size. No tea tree, so less of the antibacterial blemish angle, but excellent value for soothing.

Anua Heartleaf 80% Soothing Ampoule

Also houttuynia-led and soothing, with added hydrators like hyaluronic acid. Slightly richer and more hydrating, with no tea tree.

Centella instead of houttuynia for soothing reactive skin. Larger bottle and great for redness, but doesn't target acne bacteria the way tea tree does.

❓ Frequently Asked Questions

The formula contains no retinoids, salicylic acid, hydroquinone or chemical sunscreens, which is reassuring. However, tea tree is sometimes flagged for caution during pregnancy and breastfeeding. Because it makes up 9.7% of this serum, we recommend confirming with your OB/GYN or dermatologist before use.

Yes. The 8-ingredient formula has no fatty acids, esters, oils, polysorbates or fermented ingredients that typically feed malassezia. Houttuynia and tea tree are botanicals, and the supporting ingredients (glycereth-26, 1,2-hexanediol, arginine, carbomer, caprylyl glycol) are generally considered fungal-acne safe.

Yes, but space them out. This is a gentle soothing serum, so it layers well alongside hydrating actives like niacinamide and hyaluronic acid. With stronger actives such as retinol, vitamin C or AHA/BHA, alternate them (one AM, one PM, or on different days) to avoid stacking too much potential irritation at once.

It's best for oily, combination, acne-prone and sensitive or troubled skin that struggles with redness, congestion and breakouts. Dry skin can use it too but should layer a richer moisturizer on top, as the serum itself is lightweight.

Many users feel an immediate calming, refreshed effect. Visible reduction in redness and small bumps often appears within 1–2 weeks, with clearer pores and fewer breakouts typically developing over 4–6 weeks of consistent daily use. Results vary by skin type.

Use it at the serum/essence step β€” after cleansing and toner, and before heavier moisturizer. It can be applied morning and/or evening. In the morning, always finish with sunscreen as the final step.

No. It scores about 1 out of 5 on the comedogenic scale. The formula is oil-free and lightweight, and reviewers consistently describe it as non-clogging, making it a strong choice for acne-prone and congested skin.

Roughly 12 months after opening (12M PAO). Store it in a cool, dry place away from direct sunlight and keep the dropper sealed. Because it relies on a minimal, gentle preservative system, avoid contaminating the dropper with dirty fingers.

4.4 out of 5

Verdict: The Mary & May Houttuynia Cordata + Tea Tree Serum is a standout minimalist soothing serum that punches well above its price. With 85% houttuynia and 9.7% tea tree in just 8 fragrance-free, fungal-acne-safe ingredients, it's an excellent everyday pick for oily, combination and troubled skin that wants to calm redness and care for pores. The main trade-offs are the small 30ml size, a faint natural tea tree note, and a lightweight finish that dry skin will want to layer over. For sensitive, blemish-prone skin chasing clean, effective value, it's an easy recommendation β€” just patch test for tea tree and check with a doctor if pregnant.

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.

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. 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

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.
